Problems solved by technology

PVC products often use small-molecule plasticizers, such as dioctyl phthalate, liquid paraffin, epoxy soybean oil, etc. Small-molecule plasticizers are more likely to dissolve, volatilize, and migrate during processing and long-term use of such products , not only pollute the environment, but also degrade the performance of the product and lose its use value
For example, when PVC leather is used for the shelter of SUV cars, it will become sticky and make abnormal noise under high temperature explosion, which will affect the use.

Abstract

The invention relates to a high anti-adhesion coating material and a high heat-resistant anti-adhesion PVC product, belonging to the technical field of polymer materials. The high anti-adhesive coating material for PVC of the present invention includes the following components in parts by weight: 0.3-0.6 parts of acrylate copolymer, 0.2-0.3 parts of water-soluble polyurethane, 0.05-0.2 parts of wax emulsion, fluorine-silicon modified nano 0.2 to 0.4 parts of particles, 0.2 to 0.4 parts of polyacrylamide, 0.15 to 0.3 parts of polyethylene glycol, and 0.4 to 1 part of solvent; the high anti-adhesive coating material of the present invention can effectively inhibit growth when applied to soft PVC products. The plasticizer migrates, and the coated PVC product does not blister or peel.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a high anti-adhesive coating material and a high heat-resistant anti-adhesive PVC product. Background technique [0002] PVC is a polymer polymerized by vinyl chloride monomer (VCM) in peroxides, azo compounds and other initiators; or under the action of light and heat according to the mechanism of free radical polymerization. It is widely used. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. Polyvinyl chloride (PVC) artificial leather is a kind of leather-like plastic product obtained by laminating a mixture of PVC resin, plasticizer and other additives with the base cloth by calendering and other methods. The appearance of PVC artificial leather is similar to that of natural leather. It ha...
