Abstract

The invention provides a special composite ACR foaming regulator for a PVC shoe material, and relates to the technical field of ACR foaming regulators. The special composite ACR foaming regulator forthe PVC shoe material comprises the following components in parts by weight: 50-70 parts of methacrylate; 1020 parts of acrylic acid esters; 10-20 parts of styrene; 5-10 parts of acrylonitrile; 5-10 parts of a microsphere foaming agent; 0.3-0.8 part of a lubricating agent; and 0.3-0.8 part of a lubricating agent. The foaming regulator is prepared from the following raw materials in parts by weight: 50 parts of methacrylate, 15 parts of acrylate, 15 parts of styrene, 8 parts of acrylonitrile, 8 parts of microsphere foaming agent, 0.5 part of a lubricating agent and 3.5 parts of a heat-resistantmodifier. By blending the composite foaming regulator, the product can satisfy the requirements of the PVC shoe material for strength and flowability, can enhance the foaming ratio and thermal agingresistance, solves the problem of surface foaming of the PVC shoe material, and enhances the overall quality of the PVC shoe material.

Description

technical field [0001] The invention relates to the technical field of ACR foaming regulators, in particular to a special compound ACR foaming regulator for PVC shoe materials. Background technique [0002] Polyvinyl chloride, referred to as PVC (Polyvinyl chloride), is a vinyl chloride monomer (vinyl chloridemonomer, referred to as VCM) in peroxides, azo compounds and other initiators; or under the action of light and heat, it can be polymerized according to the mechanism of free radical polymerization. made polymer. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin; PVC is a white powder with an amorphous structure, a small degree of branching, a relative density of about 1.4, a glass transition temperature of 77~90°C, and begins to decompose at about 170°C , poor stability to light and heat, above 100 ℃ or after long-term sunlight exposure, it will decompose to produce hydrogen chloride, and further autocatalytic...
