Improved type hosepipe

Abstract

The invention discloses an improved type hosepipe prepared from the following raw materials in parts by weight: 25-50 parts of polyvinyl chloride resin, 3-6 parts of 1-hydroxyethyl-2-heptadecenylimidazoline, 5-10 parts of polyvinyl butyral ester, 3-6 parts of precipitated barium sulfate, 1-3 parts of triclosan, 2-5 parts of polyoxyethylene alkyl phenyl ether, 2-5 parts of benzotriazole, 4-8 parts of o-phthalic anhydride, 2-7 parts of antimony trioxide, 8-16 parts of polycarbonate, 2-4 parts of nano calcium carbonate, 3-7 parts of calcium aluminate, and 3-6 parts of citric acid. The invention provides the wear-resistant aging-resistant improved type hosepipe having the advantages of excellent stability, excellent heat resistance, strong impact resistance and obvious reinforcing and toughening effects, and enabling low temperature resistance, flexibility and electrostatic resistance to meet low temperature transport.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an improved hose. Background technique [0002] Polyvinyl chloride pipe, also known as PVC pipe, is a pipe made of thermoplastic polymer polymerized by vinyl chloride monomer. It uses polyvinyl chloride resin as the main raw material, and adds an appropriate amount of anti-aging agent, modifier, etc. It is a material made by kneading, calendering, vacuum blister and other processes. PVC pipe has strong corrosion resistance and is easy to bond. PVC has strong resistance to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons. However, PVC pipes, especially UPVC pipes, have poor heat resistance, and their tensile strength decreases in environments above 60°C...

AI Technical Summary

Problems solved by technology

However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.

However, PVC pipes, especially UPVC pipes, have poor heat resistance, and the tensile strength decreases in environments above 60°C, and the impact strength of rigid PVC plastic drainage pipes decreases in low temperature environments.

In the process of transportation, installation and use, it is prone to brittle failure; in addition, the performance of PVC pipes to withstand impact is also poor
