To rubber industry character, vulcanization time blossoms to raise the bottleneck of rubber industry productivity, restricted rubber industry to use the rapid development of the domain. As all sorts of thermoplastic the ceaseless maturity of elastomer technology, make people can'ts help suspecting, whether one day, thermoplastic the substitute that stretch experience becomes tall stretch balata, and the arena that makes balata exits the history? The change that brings possibly to new technology we dare be not broken below crooked today theory, but, from the point of current market, rubber industry not only did not shrink back evidence, show unusually tenacious outbreak instead force. Accompanying the rapid development of the market, balata processing technique matures ceaselessly, especially the ceaseless maturity of fast vulcanization technology is making up for balata balata before vulcanization time is long wait for inadequacy. In balata vulcanization process, temperature, pressure and time are the element of 3 joint action. Because balata overheat can send green coke to burn, state of the demote below function, how to realize high temperature vulcanization, shorten then the focal point that vulcanization time makes different business research and development. Improve vulcanizing system to take seriously in order to accelerate vulcanization process for increasing manufacturer place. Each auxiliary company rolls out corresponding fast vulcanization accelerant actively also with market of race to control. What manufacturer of special introduction part develops the article is new-style the auxiliary product that quickens vulcanization. Limited company of chemical industry of sea of Beijing of Shanghai of DTDC of new-style vulcanizing agent is China the earliest, also be these days is the oldest not dissolve sex is sulfureous manufacturing company. In recent years, the company is being finished not while development of sulfureous new technology and enlarge of vulcanizing agent DTDM produce dissolve sex, analyse the current situation of international vulcanization technology and development trend, positive research and development shows the product of forward position of acting vulcanization technology. The DTDC of new-style vulcanizing agent that this company develops will enter the market before long. Because DTDC of new-style vulcanizing agent does not arise in vulcanization process inferior saltpetre amine and get international attention fully, be considered as vulcanizing agent DTDM and the optimal substitute of 2 vulcanization or Mu of 6 vulcanization Qiu Lan. The intermediate that because vulcanizing agent DTDM and product of Qiu Lan Mu are below vulcanization temperature,splitting decomposition releases relic of amine radical element (base 2 armour amine base, 2 ethylamine base, 2 fourth amine base, amine of 2 the fifth of the ten Heavenly Stem base etc) , generation sends cancerous sex inferior saltpetre amine material, because DTDM of this vulcanizing agent is mixed,the production of product of Qiu Lan Mu and application are organized the limit that reachs environmental code and warning by Euramerican country, government, international. Be in especially in May 2003, publish in the European Union " strategy of prospective chemical policy " the has the effect that cause cancer chemical that DTDM of vulcanizing agent of white paper lieutenant general and product of Qiu Lan Mu include deadline to fall into disuse. In recent years international balata person of the same trade is opposite basis of limited company of chemical industry of Shanghai Beijing sea the noxiousness of vulcanizing agent DTDM and the research positive result that its affect to the environment, developing the substitute of vulcanizing agent DTDM. Current, already entered environmental experiment phase to the development of vulcanizing agent DTDC, will put in the market before long. Vulcanizing agent DTDC submits white crystallization form, melting point is 120~122 ℃ , mark of active sulfur quality is more than 0.

19. Replace vulcanizing agent DTDM with the quantity such as its, need not change the recipe of sizing material and technology. As identical as vulcanizing agent DTDM, vulcanizing agent DTDC is OK all or the part replaces sulfureous composition effective or half effective vulcanizing system. Because vulcanizing agent DTDC is below general vulcanization condition,can release sulfur of sex of yield results in work, as sulfureous as what join odd sulfur key and double sulfur key are formed between balata element, structure of network of vulcanization of this kind of balata can gift the hear resistance with vulcanization admirable glue, compression shrinks gender and Gao Dingshen stress. Vulcanizing agent DTDC still is had not gush frost, anxious burn the characteristic with rapid rate of safe, vulcanization, it is the optimal vulcanizing agent of the products of large model rubber such as tire, heat-resisting rubber products, wholesome rubber products and chromatic rubber products. Vulcuren new-style vulcanizing agent wants the rubber products vulcanization massiness, not be an easy thing. Because the diathermancy of balata is poorer, to make the area of balata interior quickly complete vulcanization, normally need heats for long to just can come true. That is to say the surface of balata material will be excessive vulcanization, be in possibly product interior is decomposed before complete vulcanization. The vulcanization that balata issues in microtherm is a feasible method, although this method is gentler, but take time is longer, and wasteful also. Place of career of the balata that do obeisance to ear passes long-term ceaseless research, development goes vulcanizing agent Vulcuren in order to solve problem of high temperature vulcanization. Raise vulcanization temperature, and won't cause rubber products heating for long below decompose, because this shortened,make a process and improve productivity. When balata vulcanization, stretch experience turns into to make coupling form steadily by line structure, form the tall flexibility with exceedingly good balata thereby can. But the thermal stability of structure of this kind of cross-linking is not special good, they can fall in high temperature because of be being exposed for a long time and decompose. This kind of changeover reacts the vulcanization of the balata that can make volume larger fails, and make its physics and chemistry deterioration. What differ with this is, below vulcanization temperature, vulcuren can be formed bridge peculiarly key, in the thermal stability with have better essentially, replace a share accordingly with Vulcuren sulfureous, apparent ground reduced changeover reaction. Make the balata product with larger volume at present, for example the balata solid tyre of project car or wide conveyer belt, because use Vulcuren, can make the production of rubber products is compared fast and more economy. In addition, the content sex of the product, for example wearability, fight Zhang Jiang is spent and fight the Dou Kewei such as tear strength to hold in very high level. PckacilTBzTD chemical name is 2 vulcanization 4 base Qiu Lan Mu, the Qiu Lan Mu that is new development of company of Er of Yi of You Ni collect kind accelerant, can replace TMTD(4 methylic Mu of 2 vulcanization Qiu Lan) , one vulcanization of TMTM(Mu of 4 methylic Qiu Lan) , TETD(2 vulcanization 4 Yi Jiqiu orchid Mu) , treatment security is better, have than TMTD longer anxious burn time, the fast vulcanization that can serve as natural balata, fourth balata and butadiene styrene rubber advocate accelerant or aid accelerant, also use at depressor of PVC balata vulcanization sometimes. TBzTD element amount is large, melting point is high, decompose not easily, reason does not arise inferior saltpetre amine; Its vulcanization speed a bit under TMTD, sex of other other people and TMTD are almost identical, already became the Qiu Lan Mu that has development latent capacity extremely at present kind vulcanization accelerant new breed. SantocureTBBS chemical name is butyl of N- father's younger brother - 2- benzene and accelerant of amine of Zun second sulphur, it is the accelerant of second sulphur amine with a kind of very good function, you Mengshan company development. When in using glue to plant with its in balata of natural balata, butadiene styrene rubber, butadiene, be being used, have vulcanization speed to measure advanced characteristic quickly with the model. Can be used alone commonly or use together with a few accelerant; When be used in tire and industrial rubber products, need to deserve to use zinc oxide and tristearin acid, mu of usable also Qiu Lan, 2 sulfur are acting amine of salt of amino formic acid, aldehyde, guanidine kind accelerant and acidity material activation. TBBS is raw material synthesis with fourth amine of father's younger brother and accelerant M, nonexistent inferior saltpetre amine causes cancerous problem, it is the accelerant breed of global dominant, consumption occupies the 35% above of global accelerant consumption. China also has partial enterprise to have miniature production, but restrict as a result of what suffer fourth amine of raw material father's younger brother, fail mass production and application, but its serve as environmental protection efficient new-style foreground of development of accelerant of second sulphur amine is very good. SantocureTBSI chemical name is butyl of N- father's younger brother double - 2- benzene and accelerant of amine of Zun second sulphur, you Mengshan company development, very safe below operation temperature, do not arise cause cancer inferior saltpetre amine. Compare with TBBS photograph, TBSI has an element to estimate big, melting point tall 30 ℃ above, thermal stability is can good, anxious burn time rate of long, vulcanization is rapid wait for an advantage, normally as common as antiscorching agent CTP, can replace TBBS completely. Additional, TBSI still has the stability that treat water, easily keep in storage; In vulcanization when natural glue, can raise balata apparently fight vulcanization to return former sex; The performance with the good performance in received compound is stuck in balata and steel wire. TBSI can be used at balata of natural balata, the fifth of the ten Heavenly Stem of butadiene styrene rubber, butadiene rubber, different to wait, apply to the furnace law carbon black with stronger basicity to mix refine sizing material and antagonism to return the thick products with former very high demand especially, active is more than the accelerant such as the CBS that uses extensively at present, NOBS. Muti_function accelerant TiBTM chemical name is N, n, n'- vulcanization Mu of Qiu Lan of 4 different butyl, by the United States solid opposes li of rare company development, be a kind to have accelerant of second sulphur amine already help accelerant action, what have antiscorching agent effect again is muti_function accelerant. In SBR/BR sizing material, when TiBTM and CTP are used with TBBS and CBS respectively, two kinds of antiscorching agent are right anxious burn defer action identical; But TiBTM still can accelerate vulcanization rate apparently, and the effect that CTP did not accelerate vulcanization, can cause vulcanization speed to drop sometimes even. The experiment makes clear, in the synthetic rubber system of SBR/BR and so on, tiBTM can be developed at the same time antiscorching agent and aid accelerant two kinds of functions. But in natural balata, of TiBTM prevent anxious effect to compare CTP difference apparently, tiBTM basically uses as aid accelerant; But TiBTM can increase natural balata fight vulcanization to return former sex, increase vulcanization temperature, change sulfureous dosage and join white carbon black to won't affect TiBTM to prevent anxious the effect that burn and accelerates vulcanization rate, and do not have bad influence to the physical function of vulcanized rubber. Improving manufacturing efficiency ceaselessly will be one of changeless themes in all sorts of technology competition. In all sorts of technologies of balata treatment and balata auxiliary, while the accelerant technology that quickens vulcanization is promoting rubber industry and development of its processing technique, will become each auxiliary supplier to continue the key of research and development.
