Formula of anti-coking polyvinylidene fluoride

Abstract

The invention discloses a formula of anti-coking polyvinylidene fluoride. The formula comprises modified polyvinylidene fluoride, an anti-coking agent, a cross-linking agent and a solubilizer, wherein the anti-coking agent is o-phthalic anhydride, the cross-linking agent is di-t-butyl peroxide, and the solubilizer is polysorbate and fatty acid ethoxylate; and the modified polyvinylidene fluoride accounts for 40%-50%, the o-phthalic anhydride accounts for 13%-17%, the di-t-butyl peroxide accounts for 11%-14%, the polysorbate accounts for 17%-18%, and the fatty acid ethoxylate accounts for 8%-11%. The prepared anti-coking polyvinylidene fluoride has the advantages of excellent dielectric property, impact resistance, high chemical stability and high using temperature.

Description

technical field [0001] The invention relates to a plastic formulation, in particular to a formulation of anti-focusing vinylidene fluoride. Background technique [0002] Polyvinylidene fluoride is a novel fluorocarbon resin with high mechanical strength and wear resistance, good weather resistance and thermal stability, and outstanding corrosion resistance, so it is a must in the chemical industry The raw materials used are irreplaceable by any metal. Polyvinylidene fluoride is widely used. It has good piezoelectricity, radiation resistance, and good thermal stability. Therefore, it is widely used in the electronics industry and transformer manufacturing. It is also widely used. Used in aerospace, military field, seawater desalination, metallurgy, wire and cable, electrical components, machinery manufacturing and other fields. [0003] However, there are still some deficiencies in meeting the requirements of mechanical parts in some special fields. As we all know, steel is ...

Problems solved by technology

[0003]However, there are still some deficiencies in meeting the requirements of mechanical parts in some special fields. As we all know, steel is a necessary material for manufacturing machinery, but it is used Strong acids, alkalis, salts, and polar solvents in the chemical industry cannot be used. However, the materials that have plagued this area for a long time have not been well developed. Some materials are available but difficult to process and cannot be used repeatedly. Therefore, in The strong corrosion chemical industry costs a lot of money every year, and the effectiveness, performance, and service life cannot meet the requirements. It is imperative to solve the research and development of special materials in this area, so that the flower industry can achieve stable and long-term development. Therefore, many companies come to find I came to Suzhou Teflon Company to research and develop high-strength, corrosion-resistant, crack-resistant and non-deformable fluoroplastic high-performance materials. Fortunately, Teflon Company is one of the earliest companies in China to develop high-performance fluoroplastics. The scientific and technological field of a material has achieved good development and breakthroughs, stabilized the quality of products, and has long-term cooperation with many companies, and has been affirmed by them, thereby deepening better development. In addition, the new The product is still in continuous research and development and trial production

[0004] The first company in China to produce magnetic drive pumps is an example. In the past, unmodified polyvinylidene fluoride was mainly used in pump valves, but its It can't meet the requirements, it can't be solved in terms of high pressure, high temperature and corrosion resistance
