Composition Analysis of Titanate Coupling Agent and Its Mechanism and Application Method

Composition Analysis of Titanate Coupling Agent and Its Mechanism and Application Method

Titanate coupling agent is a kind of novel chemical additive which has developed rapidly in the past ten years and is widely used in many production fields. Common titanate coupling agents include monoalkoxy fatty acid type, phosphate ester type, chelate type and ligand type. The application of titanate coupling agent opens up a new way for inorganic filling of polymer synthetic materials. Inorganic substances treated with titanate coupling agent are hydrophilic and organic, it is widely used in polyolefin resins and synthetic rubber and other polymer materials; the titanate coupling agent added to the polymer can improve the impact strength of the material, the amount of filler can reach more than 50%, and will not occur phase separation. Carbon black activated with titanate coupling agent, SiO2, CaCO3, metal oxide added to thermoplastics and rubber, can reduce the system viscosity, improve toughness and mechanical properties. Kan

Titanate coupling agent, an all-round coupling agent

Titanate coupling agent, an all-round coupling agent

Titanate coupling agent first appeared in the 1970 s. In December 1974, Kenrich Petrochemical Company of the United States reported a new type of coupling agent, which has a good coupling effect on many dry powders. Since then, inorganic filled polyolefin composite materials with titanate coupling agent have been published. In recent years, a series of titanate coupling agents developed by Kenrich companies in the United States have been widely used. Carbon black activated with titanate coupling agent, SiO2, CaCO3, metal oxides added to thermoplastics and rubber can reduce the system viscosity, improve toughness and mechanical properties.
