What is a titanate coupling agent? I have been introducing some commonly used titanium ester coupling agents to you before. Some friends may have heard of titanium ester coupling agents once, but they still don't know what they are. Today, the editor of Jianyi Chemical will explain what titanium ester coupling agents are
Titanium ester coupling agent is a coupling agent developed by Kenlich Petrochemical Company in the late 1970s in the United States. For thermoplastic polymers and dry fillers, there is a good coupling effect. The general formula is ROO (4-n) Ti (OX-R)’Y)n(n=2，3)
RO - is a hydrolyzable short chain alkoxy group that can react with surface hydroxyl groups of inorganic substances to achieve chemical coupling; OX - can be a carboxyl group, alkoxy group, sulfonic acid group, phosphate group, etc. These functional groups are important and determine the special functions of titanium acid esters, such as the sulfonic acid group imparting a certain degree of thixotropy to organic compounds; Pyrophosphoryloxy has flame retardant, rust proof, and adhesive enhancing properties; Phosphinoxy groups can provide antioxidant and flame retardant properties, so by selecting OX -, titanium esters can combine coupling and other special properties; R&'-' is a long carbon bond alkyl group, which is relatively soft and can bend and entangle with organic polymers, improving the compatibility between organic and inorganic substances and enhancing the impact strength of materials; Y is a hydroxyl, amino, epoxy, or double bond containing group that is attached to the end of the titanium ester molecule and can react chemically with organic compounds to bind together.
And it is generally applied in some common industries, such as;
In the plastic industry, fillers can be activated to increase filling volume, reduce resin usage, lower product costs, improve processing performance, increase product gloss, and improve quality.
In the rubber industry, the filler modification can play a reinforcing role, reduce the amount of rubber and antioxidant, improve the wear resistance and anti-aging ability of products, and significantly improve their luster.
In the paint industry, the amount of pigment filler can be increased, the dispersibility can be improved, it has anti settling effect, anti foaming effect, and the strength of the paint film can be improved. The color is bright, and it also has drying characteristics. It can reduce the baking temperature and shorten the baking time for baking paint
Wait, there are also some titanium ester coupling agents that can be applied in other industries, which can be said to have played a huge role in the industrial development of our society
