Composite high-temperature resistant PVC (polyvinyl chloride) pipe fitting

Abstract

The invention discloses a composite high-temperature resistant PVC (polyvinyl chloride) pipe fitting, which consists of the following components in parts by weight: 20 to 40 parts of PVC resin, 5 to 10 parts of plasticizing agent, 10 to 20 parts of calcium carbonate, 5 to 10 parts of epoxidized soybean oil, 3 to 5 parts of vegetable oil acid, 5 to 8 parts of impact resistant agent, 6 to 12 parts of diethylene glycol, 2 to 8 parts of tetrabutyl orthotitanate and 3 to 5 parts of paraffin. According to the composite high-temperature resistant PVC pipe fitting, due to the addition of the tetrabutyl orthotitanate, the oxidation resistance of the PVC pipe fitting can be greatly improved, and the PVC pipe fitting is low in cost and suitable for popularization and application; compared with the prior art, the PVC pipe fitting manufactured according to the formula has the characteristics of strong strength and high toughness, is high in impact resistance and low in component cost, and has high market competitiveness.

Description

[0001] technical field [0002] The invention relates to a PVC pipe fitting made of composite high temperature resistant material. Background technique [0003] 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 [0004] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a PVC pipe fitting made of composite high-temperature-resistant material with low cost, anti-aging, and equal emphasis on strength and impact resistance. [0005] In order to solve the above-mentioned technical problems, the techn...
