Environment-friendly PVC hose material

Abstract

The invention provides an environment-friendly PVC hose material. The material is prepared from the following components in parts by weight: 40-80 parts of polyvinyl chloride (PVC) resin, 10-15 parts of thermoplastic polyurethane elastomer, 10-20 parts of stearic acid, 4-5 parts of carboxymethyl cellulose, 2-4 parts of methyl tertiary-butyl ether, 0.4-0.6 part of triolamine phosphate, 4-5 parts of iodine tincture, 2-4 parts of lithopone, 10-20 parts of polycarbonate and 2-4 parts of nano-calcium carbonate. According to the material, the thermoplastic polyurethane elastomer, plasticizer, thermal stabilizer, antistatic agent and flame retardant are added into the PVC resin, so that the low-temperature resistance, flexibility, electrostatic resistance and flame retardance of the PVC hose can be improved, and the prepared PVC composite hose has good comprehensive performance, cannot be easily aged, and can be applied to storage and use processes of low-temperature oil, gas or liquid.

Description

technical field [0001] The invention relates to an environment-friendly PVC hose material. Background technique [0002] Polyvinyl chloride (PVC) is light yellow translucent and shiny. Transparency is better than polyethylene and polystyrene, worse than polystyrene [0003] Ethylene, depending on the amount of additives, can be divided into soft and hard PVC. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene, but lower than that of polypropylene, and whitening will appear at the inflection point. . The performance of polyvinyl chloride is relatively stable, it is not easy to be corroded by acid and alkali, and it is relatively resistant to heat; it has the advantages of flame retardancy, high chemical resistance, high mechanical strength and electrical insulation performance. [0004] Polyvinyl chloride (PVC) is used to manufacture various soft and hard pipes, and is widely used in industry, a...

Problems solved by technology

[0006] Vinyl hoses, commonly used PVC hoses, have poor low temperature resistance, high brittleness, low toughness, poor aging resistance, low safety performance, inconvenient transportation and installation, high production costs, and cannot meet the requirements of production and life.

In the prior art, a combination house of nano-calcium carbonate modified spirally wound PVC hose for sanitary ware and its preparation method are mentioned, but the soft hose made of this material

[0007] The heat resistance of the tube is better, but the low temperature resistance is poor
