The Development Status and Application of Borate Coupling Agent

The borate coupling agent is a new-style coupling agent. Compared with traditional coupling agents, it has many new features. Boric acid ester coupling agent, which centers on boron atom, can be applied to surface modification of inorganic fillers containing boron and improve the compatibility of inorganic filler containing boron and polymer. It possesses the boron-oxygen skeleton,which can present great physical sorption ca- pacity to borate whisker. In terms of modification borate whisker,boric aeid ester coupling agent has a good modification effect. In recent years, do- mestic institutions have gained great progress in the synthesis and application of boric acid ester coupling agent, which is mainly used for the preparation of composite materials. The development status of borate coupling agent and the application in composite material at the present time is summarized. Further more, the application prospect of borate coupling agent is introduced.
