Problems solved by technology

[0002] The hose of PVC pipe is high in quality and low in price. It is currently recognized as the most widely used outdoor water pipe. However, the hose made of existing PVC hose has some defects, such as long-term exposure to wind and sun, aging Fast, the current way to overcome this defect is to add antioxidants and ultraviolet absorbers, but the added substances are relatively expensive, resulting in higher production costs for PVC hoses

Abstract

The invention discloses a PVC (polyvinyl chloride) tube formula which comprises the following components in parts by weight: 40-60 parts of PVC resin, 2-3 parts of plasticizer, 15-20 parts of calcium carbonate, 1-5 parts of epoxy soybean oil, 3-5 parts of hexamethylphosphoramide, 5-10 parts of impact modifier, 2-8 parts of zinc oxide and 0.5-1 part of paraffin. The added hexamethylphosphoramide can greatly improve the oxidation resistance of a PVC tube and is low in cost, thereby being suitable for popularization and application. Compared with the prior art, the PVC tube prepared from the formula has the characteristics of high strength and high toughness, is high in impact resistance and low in price of product components, and has great market competitiveness.

Description

technical field [0001] The invention relates to a PVC pipe material formula. Background technique [0002] The hose of PVC pipe is high in quality and low in price. It is currently recognized as the most widely used outdoor water pipe. However, the hose made of existing PVC hose has some defects, such as long-term exposure to wind and sun, aging Fast, the current way to overcome this defect is to add antioxidants and ultraviolet absorbers, but the added substances are relatively expensive, resulting in higher production costs for PVC hoses. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a PVC pipe formula with low cost, anti-aging and equal emphasis on strength and impact resistance. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a PVC pipe formulation, which consists of the following...
