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 ...
