摘要
以聚乙烯醇类高分子偶联剂作改性剂，对陶土、粉煤灰和硫酸铝渣等无机填料进行改性，制成新型橡胶补强剂。讨论了新型补强剂中偶联剂及三乙醇胺用量对橡胶力学性能的影响。试验结果表明，填料与高分子偶联剂和三乙醇胺用量之比为１：（０．５—１．０）：（０．００５—０．０１０）时，胶料的力学性能最佳。与炭黑的对比试验结果表明，所研制的几种新型补强剂均可替代通用炭黑应用于橡胶制品。
The new rubber reinforcing agents were made by the modification of inorganic fillers, such as clay, coal powder and aluminum sulfate residue with polyvinyl alcohol coupling agent. The effect of the levels of the coupling agent and triethanolamine used in the new reinforcing agents on the mechanical properties of the compounds was discussed. The test results showed that the optimum mechanical properties could be obtained with the filler/coupling agent/triethanolamine ratio of 1: (0. 5-1. 0): (0. 005-0. 010).The test of comparison to carbon blacks showed that the developed new reinforcing agents might replace the general-purpose carbon blacks in rubber products.
