Problems solved by technology

[0002] At present, the existing PVC pipes include hard and soft pipes, and soft pipes are widely used. However, due to natural factors such as wind and sun, their anti-oxidation and aging properties are worse than PVC hard pipes, and they are not resistant to high pressure. , so the service life of the PVC hose is greatly reduced, which hinders the actual application

Abstract

The invention discloses a high-pressure PVC (Poly Vinyl Chloride) hose material. The hose material consists of the following components in parts by weight: 70-80 parts of polrvinyl chloride resin, 1-2 parts of a plasticizer, 10-20 parts of stearic acid, 3-5 parts of hexamethylphosphoramide, 1-2 parts of an anti-ultraviolet agent, 2-3 parts of powdered butyronitrile and 2-8 parts of zinc oxide. Through the addition of the hexamethylphosphoramide, the antioxidant property of the PVC tubular product is greatly enhanced; and the added powdered butyronitrile is used as a PVC property enhancer, so that the property of the tubular product is obviously enhanced, the tubular product has high strength, the pressure-resistant property is enhanced, the tubular product is especially suitable for a low-temperature environment and the cost is low.

Description

technical field [0001] The invention relates to a high-pressure PVC hose material. Background technique [0002] At present, the existing PVC pipes include hard and soft pipes, and soft pipes are widely used. However, due to natural factors such as wind and sun, their anti-oxidation and aging properties are worse than PVC hard pipes, and they are not resistant to high pressure. , so the service life of the PVC hose is greatly reduced, hindering the actual application. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a PVC material formula with low cost, good anti-aging effect and high pressure resistance. [0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a high-pressure PVC hose material, which consists of the following components by weight: [0005] Polyvinyl chloride resin 70~80; [0006] Plast...
