Problems solved by technology

Although SAN polymers can greatly reduce the melt viscosity of PVC and improve its fluidity, but due to poor compatibility with PVC, the mechanical properties of the product will suffer a large loss.
There is a large difference in processing temperature between TPU, PA and PVC; rare earth polyesters, liquid crystal polymers, hyperbranched polyesters and other raw and auxiliary materials are scarce, the production process is complicated, the manufacturing is difficult, and the product cost is high, so it is difficult to use on a large scale in the PVC industry

Abstract

The invention discloses a high-impact and high-flow polyvinyl chloride material and preparation method thereof. The material has good high-low temperature impact resistance and excellent processing fluidity, and is a composite material which takes the polyvinyl ethylene as the base material and is blended and modified. The material is specifically prepared from the following components in parts byweight: 100 parts of polyvinyl chloride resin, 2-5 parts of heat stabilizer, 1-3 parts of lubricant, 0.5-2.5 parts of processing auxiliary, and 5-20 parts of composite impact modifier. The polyvinylchloride modified material provided by the invention can be used for preparing various pieces through an injection molding way, the traditional ABS material with expensive price is replaced, and the polyvinyl chloride material can be used for wine external package and decorative materials with an electroplating demand.

Description

technical field [0001] The invention belongs to the field of polyvinyl chloride polymer materials, and in particular relates to a high-impact high-fluidity polyvinyl chloride material and a preparation method thereof. Background technique [0002] Since the molecular structure of polyvinyl chloride contains chlorine atoms with extremely strong electronegativity, it will cause structural defects, poor thermal stability, poor fluidity, poor impact resistance, and difficult processing. It is about 130 °C without adding stabilizers. It will decompose, and the notched impact strength at room temperature is only 2-3KJ / m 2 , and can not meet the actual needs, therefore, at the beginning of the birth of PVC, people are determined to solve its impact resistance, fluidity and other issues. [0003] The rigid and high-flow PVC patents we are concerned about generally achieve impact resistance and high fluidity through two methods. On the one hand, alloy materials are added, such as MB...
