The invention provides functionalized rubber, a preparation method of the functionalized rubber, a composite material of the functionalized rubber and application of the composite material. The functionalized rubber is prepared by uniformly mixing raw materials including rubber and a polyfunctional group sulfydryl reagent and carrying out heat treatment; the molar ratio of the polyfunctional group sulfydryl reagent to rubber double bonds is (0.01-0.9): 1; according to the preparation method of the functionalized rubber, the functionalized rubber in the chain is prepared by adopting a solid-phase functionalization method, a solvent does not need to be added, the operation is simple, the cost is low, post-treatment is not needed, and the defects that the cost is high, the pollution is heavy, the process is complex and the like when rubber functionalization modification is carried out in a solution are overcome.

    本发明提供了一种官能化橡胶及其制备方法和其复合材料及应用。所述官能化橡胶由包括橡胶、多官能团巯基试剂在内的原料混合均匀,经热处理后制备而得;所述多官能团巯基试剂与橡胶双键的摩尔比为(0.01~0.9):1;本发明的官能化橡胶的制备方法,采用固相官能化的方法制备链中官能化橡胶,无需加入溶剂,操作简单,成本低廉,无需后处理,解决了在溶液中进行橡胶官能化改性,存在的成本高、污染重、工艺复杂等缺点。
