Abstract

The invention relates to a polyvinyl chloride-based compatilizer, which is prepared from the following raw material ingredients including PTMEG sodium modified polyvinyl chloride, modified stearyl chloride, hexanedioic acid, hydroxyl silicone oil, polyoxyethylene polyoxypropylene segmented copolymers, dichlorophosphite pentaerythritol ester diisodecyl and magnesium stearate, wherein the PTMEG sodium modified polyvinyl chloride is prepared from polyvinyl chloride, PTMEG sodium, isopropanol and dimethylformamide through reaction; the PTMEG sodium is prepared from PTMEG, sodium phenate, ethyl alcohol and dimethylformamide through reaction. The polyvinyl chloride-based compatilizer has the effects of improving the material compatibility and the mechanical intensity.

Description

technical field [0001] The invention relates to a polyvinyl chloride-based compatibilizer and a preparation method thereof. Background technique [0002] At present, plastic compatibilizers have defects such as poor compatibility with plastics and poor dispersibility. Polyvinyl chloride is one of the commonly used plastic products. Using polyvinyl chloride as the base resin, a compatibilizer for plastics with excellent compatibility and dispersion is prepared. [0003] The invention uses sodium polytetrahydrofuran ether glycolate modified polyvinyl chloride, modified stearyl chloride, adipic acid, hydroxyl silicone oil, polyoxyethylene polyoxypropylene block copolymer to prepare a polyvinyl chloride-based compatibilizer, the method The prepared polyvinyl chloride-based compatibilizer can improve the compatibility and mechanical strength of materials. Contents of the invention [0004] The purpose of the invention is to provide a preparation method of a polyvinyl chloride...
