Market report of titanate coupling agent
Release Date:
2021-11-22
Titanate coupling agent is a coupling agent developed by Kenledge Petrochemical Company in the late 1970 s. For thermoplastic polymers and dry fillers, there is a good coupling effect; This kind of coupling agent can be expressed by the general formula: ROO(4-n)T(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; 0X-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-specific thixotropy; Pyrophosphoryloxy group has flame retardant and rust prevention, and enhances adhesion. Phosphoryloxy group can provide anti-oxidation, flame resistance, etc., so through the selection of 0X-, 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. Application in the plastic industry, can make the filler get activation treatment, so as to improve the filling, salty resin, reduce the cost of products, while improving the processing performance, increase the product gloss, improve the quality.
1. Application
Applied in the rubber industry, the filler modification can play a reinforcing role, can reduce the use of rubber and antioxidant, improve the wear resistance and aging resistance of the product, and 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.
Application in the paper industry, the dispersion of calcium carbonate or talc powder is improved, the loss is greatly reduced, and its filling is improved. Charge, enhance paper strength, improve paper printing performance, etc.
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 improving its filling, increasing the magnetic density and significantly improving the magnetic signal.
In short, due to the special structure of titanium, it has a variety of unique functions. At present, all countries in the world are actively carrying out research on the application of titanium. Titanium is the fourth metal element in the earth's crust, and China is rich in reserves. In addition to carrying out titanium alloy research in China, there are titanium chemistry. Only the study of organic titanium coupling agent has nearly 20 scientific research units and colleges and universities. The development and application of organic titanium compounds is the current international development direction, its application range is broad, the effect is significant, which is of great significance to the development of China's chemical industry and improve the quality of your factory products, reduce costs and improve efficiency.
Tetravalent elements are the best molecular builders, such as tetravalent titanium carbon, which forms the basis of life. The same titanium chemistry shows that tetravalent titanium allows chemists to synthesize titanates of various molecular types as coupling agents, which in addition to providing good coupling for different fillers and polymer systems, also show a variety of other functions. The molecule of titanate coupling agent can be divided into six functional regions, which play their respective roles in the coupling mechanism.
