Titanate coupling agent is a new product after silane coupling agent. It is mainly used to solve the problem of lack of coupling effect of silane coupling agent on thermoplastics such as polyolefin. It was first developed by a chemical company in the 1970s. With the passage of time, the types of titanate coupling agents developed and recognized by more and more people. At present, it is widely used in electronics, automobiles, construction, plastics, rubber, coatings, inks, etc.

       Like the silane coupling agent, the titanate coupling agent is also a compatibilizer that can build a molecular bridge between the inorganic filler and the polymer interface, but unlike the silane coupling agent, the titanate coupling agent The agent is a coupling agent derived from titanium atoms. Compared with the silane coupling agent, there are mainly the following two differences:

       1. The inorganic end of the silane coupling agent is more suitable for fillers containing silicon or water, while the titanate coupling agent is more suitable for calcium carbonate, barium sulfate, carbon black and other fillers, especially calcium carbonate, which are used in plastics and thermoplastic elastomers. There are many applications in calcium carbonate, so the appearance of titanate coupling agent is of great significance to the application of calcium carbonate;

       2. The organic end of the silane coupling agent is easier to react with thermosetting resins, while the titanate coupling agent tends to be connected with thermoplastics.

       Therefore, in summary, titanate coupling agent is more suitable for thermoplastic resin and inorganic mineral powder filler system. Appropriate use can significantly improve the mechanical properties and processing rheological properties of highly filled resins. 0.5%~2%. It is of great assistance to achieve high filling and low cost. In rubber and elastomers, titanate coupling agent can also play a role in improving the reinforcing effect of fillers on the mixed rubber, reducing Mooney viscosity, improving processing performance; improving the wear resistance, tear strength and resistance of rubber. Aging ability, improve surface finish and gloss of finished products, etc.
