Abstract

The invention discloses a PVC resin engineering plastic material preparation process and application thereof. The method comprises the steps that polyvinyl chloride resins and water-based acrylic resins are mixed and dried in an air-blowing dryer, and then dried mixtures are added into an internal mixer; neopentyl glycol diacrylate, hydroxypropylmethyl cellulose and nanometer antimony trioxide areadded for banburying, smelted products are added to a reactor still for reaction and then added to a twin-screw extruder for extrusion granulation, and plastic masterbatches are obtained through cooling and pelletion: finally, the plastic masterbatches are dried and ground into powder, and the powder is added in a mixing mill with ethyl acetate solution for mixing to obtain a finished material through film blowing of a single-screw film blower. The prepared engineering plastic material has high mechanical strength and good insulation performance, and has a good application prospect in the preparation of plastic valves and pipe fitting products.

Description

technical field [0001] The invention relates to the technical field of plastic materials, in particular to a preparation process and application of a PVC resin engineering plastic material. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Pipes are mainly used for water supply system piping, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation in housing construction. In construction engineering, pipes and valves need to be installed and used together, and they are an inseparable set of components. [0003] Traditional valves and pipes are mainly made of metal materials. When metal materials meet the mechanical strength, there are often problems such as heavy weight, easy corrosion, and hea...
