Abstract

The invention relates to a PVC plastic processing aid. The PVC plastic processing aid is prepared from the following raw materials in parts by weight: 2-6 parts of talcum powder, 1-3 parts of a lubricant, 0.8-2.5 parts of modified chitosan, 0.6-1.2 parts of alginate, 0.3-0.8 part of sodium fluoride, 10-20 parts of galvanized carbon black, 4-7 parts of sodium carbonate, 6-8 parts of ternary vinyl chloride-vinyl acetate resin, 20-35 parts of deionized water, 10-16 parts of butyl acrylate, 2-3 parts of pentaerythritol triacrylate, 2-4 parts of polystyrene, 0.5-1.5 parts of maleic anhydride, 1-3 parts of glycerin and 6-9 parts of zinc stearate. The PVC plastic processing aid has the beneficial effects that the heat resistance and the weather resistance are very good, the aging of the plastic can be effectively delayed, the production cost is saved, and the PVC plastic processing aid is suitable for being widely applied.

Description

technical field [0001] The invention relates to a PVC plastic processing aid. Background technique [0002] PVC is one of the five general-purpose plastics in the world. In recent years, with the rapid development of my country's national economy, PVC products have grown at a rate of more than 20% every year. By 2005, the annual output of PVC has reached 7.5 million tons. It is predicted that by 2007 PVC demand will exceed 10 million tons. Polyvinyl chloride (PVC) is a general-purpose plastic with a wide range of uses. It has an irreplaceable position in the fields of chemical building materials, chemical anti-corrosion and daily products. The ductility of PVC melt is poor, which can easily lead to melt breakage; PVC melt can relax slowly, which can easily lead to rough, dull and shark skin on the surface of the product. Therefore, it is often necessary to add processing aids during PVC processing to improve the above-mentioned defects of its melt. Processing aids are main...
