A kind of high-strength PVC pipe and its processing technology

Abstract

The invention discloses a high-strength PVC (polyvinyl chloride) pipe material. The high-strength PVC pipe material comprises a PVC layer, a bonding layer and a carbon fiber cloth layer; the carbon fiber cloth layer wraps the outer part of the PVC layer through the bonding layer; a plurality of reinforced connecting grooves are formed in the surface of the outer side of the PVC layer; four reinforced ribs are horizontally arranged on the inner side of the PVC layer; the PVC layer comprises the following raw material componentsincluding, by weight,30-35 parts of PVC resin, 15-20 parts of chlorinated polyethylene, 10-15 parts of ethylene-propylene rubber, 5-8 parts of acetylene-propylene copolymer, 2-4 parts of a stabilizer, 8-12 parts of filler and 1-3 parts of beta-cyclodextrin. Through the reinforced ribs, the internal supporting strength of the PVC pipe is enhanced and use in actual life is facilitated; and through the carbon fiber cloth layer, the carbon fiber cloth layer has high strength, low density and small thickness, does not increase the self-weight of a reinforcing component and the section size, is suitable for various structure types and greatly enhances the external supporting strength of the PVC pipe.

Description

technical field [0001] The invention relates to the field of PVC pipes, in particular to a high-strength PVC pipe and its processing technology. Background technique [0002] The main component of PVC is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is Back-coated adhesive; it is made of polyvinyl chloride resin, stabilizer, lubricant, etc. and then extruded by hot pressing method. It is the earliest plastic pipe that has been developed and applied; PVC-U pipe has strong corrosion resistance and is easy to bond , low price, hard texture, but due to the leakage of PVC-U monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45°C. Plastic pipes are used for drainage, waste water, chemicals, heating fluid and cooling fluid , food, ultrapure...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-strength PVC pipe and its processing technology. In order to overcome the above-mentioned existing PVC pipe, which is not as flexible as other plastic pipes, has poor thermal stability and impact resistance, it is easy to use whether it is hard or soft PVC. It produces brittleness, its own strength is still insufficient during use, and it is prone to damage technical problems during use
