Abstract

The invention discloses a PVC plastic pipe fitting prepared from the following raw materials in parts by weight: 30-50 parts of ASA resin, 9-15 parts of a thermoplastic polyurethane elastomer, 7-14 parts of butyl acrylate, 7-14 parts of magnesium hydroxide, 22-42 parts of polyvinyl chloride resin, 11-16 parts of nitrile rubber powder, 10-16 parts of crosslinked starch, 8-16 parts of attapulgite, 9-14 parts of silicon carbide whisker and 6-9 parts of a lubricant. The PVC plastic pipe fitting provided by the invention has the advantages of high toughness, high rate of elongation, good anti-aging effect, high strength, low cost and good corrosion and high-temperature resisting effects.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a PVC plastic pipe fitting. Background technique [0002] At present, PVC pipes are widely used in water supply, construction, drainage, sewage, chemical and other technical fields because of their strong corrosion resistance, high strength, and good rigidity. However, due to the poor wear resistance of PVC pipes and the inability to use them in high-temperature environments, the use of PVC pipes is largely restricted. In the prior art, there are PVC pipes with high-temperature-resistant components, but the high-temperature resistance effect is relatively low. Difference. In recent years, flame-retardant PVC pipes have emerged and are widely used in various fields. The non-halogenation of flame retardants has become the mainstream of the flame retardant industry, and inorganic flame retardants such as aluminum hydroxide and magnesium hydroxide have developed rapidly....
