Titanate coupling agent series application
Release Date:
2021-06-08
Titanate coupling agent series:Titanate coupling agent is a coupling agent developed by Kenledge Petrochemical Company in the late 1970 s. For thermoplastic polymers and dry fillers, it has good coupling effect. This kind of coupling agent can be expressed by the general formula: ROO(4-n)Ti(OX-R 'Y)n (n = 2,3); Where RO-is a hydrolyzable short chain alkoxy group that can react with hydroxyl groups on the surface of inorganic substances to achieve the purpose of chemical coupling; OX-can be carboxyl group, alkoxy group, sulfonic acid group, phosphorus group, etc, these groups are very important and determine the special functions of titanate, such as sulfonic acid group giving organic matter certain thixotropy; Pyrophosphoryl oxy group has flame retardant, rust-proof and adhesion-enhancing properties. Phosphoryl oxy group can provide anti-oxidation, flame resistance, etc., so through the selection of OX-, titanate can have both coupling and other special properties. R'-is a long carbon bond group, which is relatively soft, it can be bent and entangled with organic polymers, so that the compatibility of organic and inorganic substances is improved, and the impact strength of the material is improved; Y is hydroxyl, amino, epoxy or double-bond-containing groups, etc. These groups are connected at the end of titanate molecules and can be combined with organic substances through chemical reactions. Applied in the plastics industry, the filler can be activated, thereby increasing the amount of filling, reducing the amount of resin, reducing the cost of products, while improving processing performance, increasing the gloss of the product, and improving the quality.
Application in the rubber industry, the filler modification can play a reinforcing role, can reduce the amount of rubber and antioxidant dosage, improve the wear resistance and aging resistance of the product, its gloss has also been significantly improved.
Application in the coating industry, can increase the amount of pigment filler, dispersion performance is improved, with anti-settling effect, can prevent hair, paint film strength is improved, bright color, but also has the characteristics of drying, baking paint can also reduce the baking temperature and shorten the baking time.
Application in the pigment industry, can make the pigment dispersion has been significantly improved. Can shorten the grinding dispersion time, so that the product color bright.
Applied in the paper industry, the dispersion of calcium carbonate or talc powder is improved, the loss is greatly reduced, and the filling amount is increased, the strength of the paper is enhanced, and the printing performance of the paper is improved.
Applied in the oilfield industry, it can improve the gelling performance of fracturing fluid, heat resistance temperature, downhole depth and permeability, and has a significant effect on improving oil recovery.
Applied in the magnetic material industry, the dispersion of magnetic powder has been significantly improved, and the affinity with the base or carrier has been enhanced, thus increasing the filling amount, increasing the magnetic density and significantly improving the magnetic signal.
