PVC (polyvinyl chloride) hose

Abstract

The invention discloses a PVC (polyvinyl chloride) hose which is prepared from the following components in parts by weight: 30-60 parts of PVC resin, 2-5 parts of polytrimethylene terephthalate, 0.1-0.3 part of glyoxal, 1-3 parts of panthenol, 1-2 parts of chlorhexidine cycloacetate, 0.5-0.7 part of saccharomycetin, 2-5 parts of organic silicon compounded rubber, 10-15 parts of styrene-butadiene rubber, 1-3 parts of carbon black and 1-2 parts of paraffin. The silicon carbide whisker used in the high-toughness PVC hose can effectively reinforce the internal structure of the hose, and enhances the mechanical strength and toughness of the hose. In addition, the aging resistance of the hose is enhanced; and the lubricant can enable the material to be more uniform, enhances the extrusive lubricating smoothness, and has the action of reinforcing the internal structure in the production process. The prepared PVC hose has the characteristics of high toughness and high mechanical strength.

Description

Technical field [0001] The invention involves a PVC hose. [0002] Background technique [0003] Polyvinyl chloride tube, also known as PVC tube, is a pipe made of armoplastic polymer aggregated by chloroly chloride monomer.Materials made by mixed, pressure -extended, vacuum -sucking and other processes.PVC tube has strong resistance to corrosion capacity, easy to bond, and PVC has strong resistance to oxidants, reducing agents and strong acids.However, it can be corroded by concentrated sulfuric acid, concentrated nitric acid, and is not applicable to contact with aromatherapy and chlorine chloride.However, the PVC tube, especially the UPVC tube, has poor heat resistance, and decreased the tensile strength of the environment above 60 ° C. The impact strength of the hard polyethyl chloride plastic drainage pipe in low temperature environments is reduced.During transportation, installation and use, it is prone to crispy damage; in addition, the PVC tube has poor performance.

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 their 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
