PVC hose

Abstract

The invention discloses a PVC hose. The hose is prepared from the following components in parts by weight: 30-60 parts of PVC resin, 1-3 parts of chlorhexidine hydrochloride, 1-2 parts of lauryl alcohol polyoxyethylene ether, 0.4-0.6 part of turpentine, 2-5 parts of organic silicone rubber masterbatch, 10-15 parts of butadiene styrene rubber, 1-3 parts of carbon black and 1-2 parts of paraffin. The high-toughness PVC hose is prepared from silicon carbide whiskers, so that the internal structure of the hose can be effectively reinforced, and the mechanical strength and toughness among hoses can be improved. Furthermore, the aging resistance of the hose can be improved; and by means of a lubricant, the material can be uniform in the production process, the extrusion smoothness can be improved, and the effect of reinforcing the internal structure can be achieved. The prepared PVC hose has the characteristics of high toughness and high mechanical strength.

Description

technical field [0001] The invention relates to a PVC 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, and the impact strength of hard polyvinyl chloride plastic drain...

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 hard 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
