Preparation method of auxiliary for plastic pipe processing

Abstract

The invention provides a preparation method of an auxiliary for plastic pipe processing. The auxiliary is prepared from raw materials in parts by weight as follows: 2-6 parts of talcum powder, 1-3 parts of a lubricating agent, 0.8-2.5 parts of modified chitosan, 0.6-1.2 parts of alginate, 0.3-0.8 parts of sodium fluoride, 10-20 parts of zinc plated carbon black, 4-7 parts of sodium carbonate, 6-8parts of vinisol, 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 preparation method has beneficial effects as follows: the auxiliary for plastic pipe processing has good heat resistance and weather fastness and can effectively delay plastic aging, production cost is saved, and wide application is facilitated.

Description

Technical field [0001] The invention relates to a preparation method of an auxiliary agent for plastic pipe processing. Background technique [0002] Plastic products are one of the world’s five major general-purpose plastics. In recent years, with the rapid development of my country’s national economy, plastic products have grown at an annual rate of more than 20%. By 2005, the annual output of plastic products has reached 7.5 million tons. It is predicted that In 2007, the demand for plastic products will exceed 20 million tons. Plastic pipe is a universal plastic with a wide range of uses, and it has an irreplaceable position with other materials in the fields of chemical building materials, chemical anti-corrosion and daily-use products. The melt ductility of plastic pipes is poor, which can easily lead to melt fracture; the melt of plastic pipes relax slowly, which can easily lead to rough, dull and shark skin on the surface of the product. Therefore, it is often necessary ...
