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.
