Problems solved by technology

[0002] PVC pipe hoses are high in quality and low in price, and are currently recognized as the most widely used outdoor water pipes. However, there are some defects in the hoses made of existing PVC hoses, such as long-term exposure to wind and sun outdoors, aging is relatively 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 pipe formula. The PVC pipe formula consists of the following components in parts by weight: 40-50 parts of PVC resin, 2-4 parts of stearoylbenzoylmethane, 5-12 parts of high-polymer ester calcium, 2-5 parts of epoxidized soybean oil, 3-6 parts of tribasic lead sulfate, 5-12 parts of an impact-resistant agent, 2-8 parts of zinc oxide, and 1-2 parts of paraffin. The PVCpipe formula provided by the invention has the advantages that the added hexamethylphosphoric triamide can not only greatly improve the oxidation resistance of a PVC pipe, but also has low cost, andis suitable for popularization and application. Compared with the prior art, the PVC pipe prepared according to the formula provided by the invention has the characteristics of high strength and hightoughness, and is strong in impact resistance, low in product component price, and strong in market competitiveness.

Description

technical field [0001] The invention relates to a PVC pipe formulation. Background technique [0002] PVC pipe hoses are high in quality and low in price, and are currently recognized as the most widely used outdoor water pipes. However, there are some defects in the hoses made of existing PVC hoses, such as long-term exposure to wind and sun outdoors, aging is relatively 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 formula, which is com...
