Problems solved by technology

PVC pipes have the advantages of acid resistance, alkali resistance, corrosion resistance, and high strength. However, the impact resistance of PVC pipes produced by major manufacturers is not good, especially in the plasticization process of PVC products. The dispersion and processing fluidity of PVC melt have always been a problem

Abstract

The invention discloses a formula of an impact-resistant PVC (Polyvinyl Chloride) tubular product. The formula comprises the following components in parts by weight: 25-40 parts of ASA (Acrylonitrile Styrene Acrylate copolymer) resin, 3-5 parts of a lubricant, 5-10 parts of PE (Polyethylene) wax, 4-8 parts of ultrathin light calcium carbonate, 3-6 parts of a flame retardant, 5-10 parts of titanium pigment, 7-12 parts of titanium dioxide and 3-5 parts of magnesium hydroxide. The formula is further optimized, so that the dispersion of inorganic filler is accelerated in the processing process of the PVC tubular product to improve the fluidity of the PVC melt, the tensile strength and the breaking elongation can be further enhanced, and the deficiency that a polyethylene product is good in toughness and low in hardness when chlorinated polyethylene is used is solved.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to an impact-resistant PVC pipe formula. Background technique [0002] The main component of PVC pipe is polyvinyl chloride, and plasticizers, anti-aging agents and other auxiliary materials are added to increase its heat resistance, toughness, ductility, etc. PVC is a well-loved, popular and widely used synthetic material in the world today. PVC pipe is a mature pipe, mainly used in water supply and drainage projects. PVC pipes have the advantages of acid resistance, alkali resistance, corrosion resistance, and high strength. However, the impact resistance of PVC pipes produced by major manufacturers is not good, especially in the plasticization process of PVC products. The dispersion and processing fluidity of PVC melt has always been a difficult problem. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be sol...
