The invention provides functionalized rubber, a functionalized rubber nano composite material as well as a preparation method and application of the functionalized rubber nano composite material. The functionalized rubber is obtained by carrying out click reaction on a sulfydryl reagent and rubber containing double bonds in the presence of a side reaction inhibitor, and the obtained functionalized rubber and a rubber additive are mixed and vulcanized to obtain the functionalized rubber nano composite material. According to the method, the defects that in the rubber functionalization process, many side reactions exist, the click reaction is difficult to control and the like are overcome, the side reactions such as carbon-carbon crosslinking in the reaction process are effectively inhibited, the click rate is increased, the prepared high-performance functionalized rubber is low in Mooney viscosity and good in processability, and the method is easy to operate and easy to apply and popularize.

    本发明提供了一种官能化橡胶、官能化橡胶纳米复合材料及其制备方法和应用。官能化橡胶由巯基试剂和含有双键的橡胶在副反应抑制剂的存在下发生点击反应得到,将得到的官能化橡胶与橡胶助剂混炼后硫化得到所述官能化橡胶纳米复合材料。本发明解决了在橡胶官能化过程中存在的副反应多、点击反应难以控制等缺点,有效地抑制了反应过程中发生的碳碳交联等副反应,提高了点击率,制得的高性能官能化橡胶的门尼粘度低,加工性能好,且方法操作简单,易于推广应用。
