This invention discloses a kind of silicone coupling reagent that contains thiocarbamate unit and its preparation method, that is, mercaptoalkylsilane and alkyl monoisocyanate react with each other at a mole ratio of 1:1 in organic solvent with the existence of tertiary amine catalyst. The mixture is then vacuum distilled to obtain a silicone coupling reagent that has one thiocarbamate unit and six alkoxyls. This method has the advantages of simple technique flow, high yield and high practicability. The sulphur-containing silicone coupling reagent based on this invention has good thermo stability and considerable coupling effect. It is a good substitution of conventional silicone coupling reagent and can be used in fumed silica-containing rubber so as to promote the comprehensive properties of vulcanized rubber. |
