Problems solved by technology

[0002] In the rubber industry, zinc methacrylate (ZDMA) or zinc acrylate (ZDA) is used as a co-crosslinking agent with excellent dynamic properties, reinforcement properties, and good adhesion properties, and is used in various peroxide-induced cross-linked rubber systems. However, these two materials have a certain degree of decomposition in the air environment as a medium-strong acid and weak-base salt, and are a powder with a pungent smell, and have a certain degree of self-aggregation, Hygroscopicity and storage risk, there are big problems in the use of industrial hygiene and environmental protection

Abstract

The invention relates to a stabilized and gelatinized zinc methacrylate or zinc acrylate. The formula comprises the following materials in parts by weight: 70-80 parts of zinc methacrylate (ZDMA) or zinc acrylate (ZDA), 10-19 parts of basic gel (at least one of ethylene-propylene methylene copolymer and polyethylene-vinyl acetate rubber), 1-3 parts of internal releasing agent, 1-5 parts of hydroquinone or aminophenol crosslinking inhibitor and 0.01-13 parts of plasticizer; the internal releasing agent is selected from fatty acid salt, aliphatic ester, fatty acyl amide or mixture thereof; the plasticizer is selected from polyester plasticizer or high-viscosity paroline and low-melting-point polyethylene wax.

Description

technical field [0001] The invention relates to the preparation of rubber additives, especially the stabilized and colloidal zinc methacrylate or zinc acrylate which is suitable for a wide range of rubber types by using low-polarity inert carrier binary ethylene propylene rubber, and the use of high The heat-resistant and oil-resistant inert carrier polyethylene-vinyl acetate rubber prepares the preparation process and formula of stabilized and colloidal zinc methacrylate or zinc acrylate in formulas that require high heat and oil resistance. Background technique [0002] In the rubber industry, zinc methacrylate (ZDMA) or zinc acrylate (ZDA) is used as a co-crosslinking agent with excellent dynamic properties, reinforcement properties, and good adhesion properties, and is used in various peroxide-induced cross-linked rubber systems. However, these two materials have a certain degree of decomposition in the air environment as a medium-strong acid and weak-base salt, and are ...
