Abstract

The invention discloses a film material with high hydrolysis resistance. Films are prepared from raw materials in parts by weight of 70-80 parts of polyvinyl chloride resin, 40-50 parts of epoxy resin and 10-15 parts of diethyl phthalate, and also comprise 1-3 parts of an antioxidant, 4-6 parts of a nanoscale filler, 2-4 parts of a compatilizer and 3-5 parts of a stabilizing agent. The film material disclosed by the invention has the beneficial effects that the epoxy resin and the diethyl phthalate which are added can effectively enable the hydrolysis resistance of the films to be improved, and besides, other substances are added, so that the stability of the films can be improved, and the service life can be prolonged.

Description

technical field [0001] The invention relates to a film material, in particular to a film material with high hydrolysis. Background technique [0002] Thermoplastic elastomers are more and more widely used due to their excellent elongation at break, resilience, wear resistance, weather resistance and superior processing and molding methods compared to cast polyurethane. In particular, due to the rapid development of the polyurethane industry, the production capacity of raw material manufacturers has been continuously expanded, and the cost has been continuously reduced, thereby promoting the application and development of new rounds of polyurethane products. However, the hydrolytic stability of existing thermoplastic elastomers is poor. The reason for the poor hydrolytic stability of thermoplastic elastomers is that after water penetrates into the elastomer, it reacts chemically with the groups in the thermoplastic elastomer, resulting in chemical degradation, the chemical c...
