Powder treating agent as well as synthesis method and use method thereof

The invention discloses a powder treating agent, the molecular formula of the powder treating agent is as follows: in the formula, n is equal to 1-8, R1 is one of 2-ethylhexyl ether, butyl ether and fatty alcohol-polyoxyethylene ether, R2 is one of 2-ethylhexyl ether, butyl ether and fatty alcohol-polyoxyethylene ether, R3 is one of methyl, methoxyl and ethoxyl, and R4 is one of methoxyl and ethoxyl. According to the technical scheme, after the powder treating agent is used, the compatibility of powder and silicone rubber base rubber becomes good; moreover, within a certain range, the adding amount of the powder treating agent is continuously increased, and the bonding force between the powder and the silicone rubber-based adhesive is gradually enhanced. 本发明公开了一种粉体处理剂，所述粉体处理剂的分子式如下，式中，n=1~8，R1为2-乙基己基醚基、丁基醚、脂肪醇聚氧乙烯醚中的一种，R2为2-乙基己基醚基、丁基醚、脂肪醇聚氧乙烯醚中的一种，R3为甲基、甲氧基、乙氧基中的一种，R4为甲氧基或乙氧基中的一种。本技术方案中，在使用该粉体处理剂后，粉体与硅橡胶基胶的相容性变好；并且，在一定范围内，不断提高粉体处理剂的加入量，粉体与硅橡胶基胶的粘接力逐渐增强。
