PVC preparation process for wire plastic particles

Abstract

The invention discloses a PVC preparation process for wire plastic particles. The preparation process includes the following materials: by weight, 50-150 parts of PVC resin, 10-15 parts of a thermal stabilizer, 30-60 parts of epoxy resin, 30-60 parts of thermoplastic polyester, 5 parts of a foaming agent, 10 parts of a toughening agent, 2 parts of an antioxidant, 1 part of a lubricant and 10-30 parts of vinyl chloride resin. The thermal stabilizer includes, by weight, 10-30 parts of organic zinc compound, 2-10 parts of organic tin compound, 20-40 parts of phthalates, 10-30 parts of alkyl esters, 10-30 parts of phosphite ester, 5-20 parts of chloro-methoxy fat diethylene glycol dinitrate, 1-5 parts of phenol and 2-8 parts of 2-ethylhexanol. The toughening agent includes a mixture of methylmethacrylate-butadiene and styrenic terpolymer (MBS), and the antioxidant is 2,6-tertiary butyl-4 methylphenol. The wire plastic particles prepared by the process are obviously superior to common PVCplastic granules on the market, have good heat resistance and high temperature resistance, high insulation capacity, high aging resistance and good toughness, and are suitable for wider electric wireindustry.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a PVC preparation process for wire plastic particles. Background technique [0002] At present, the plastic industry is widely used in all walks of life. For the common wire PVC plastic particles on the market, most of them lack good high temperature and high heat resistance, low ductility, low level of insulation ability, and are easy to age, so they can only be used as relatively low-level products. Copper wires are outsourced, and the application force of the special wire plastic coating is insufficient. Contents of the invention [0003] The object of the present invention is to provide a PVC preparation process for wire plastic granules, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A PVC preparation process for wire plastic granules,...
