Problems solved by technology

Polyvinyl chloride hose is made of polyvinyl chloride (PVC) resin. Pure polyvinyl chloride (PVC) resin belongs to a class of strong polar polymers. Its intermolecular force is relatively large, which leads to the softening temperature and melting temperature of PVC. The temperature is high, generally need 160-210 ℃ to process; the substituted chlorine group contained in the PVC molecule is easy to cause the dehydrochlorination reaction of PVC resin
At the same time, PVC hoses still have certain defects in high temperature resistance and oil resistance.

Abstract

The invention discloses a preparation method of a polyvinyl chloride hose. The polyvinyl chloride hose is prepared from 90-110 parts of polyvinyl chloride resin, 8-15 parts of dioctyl phthalate, 35-45 parts of tritolyl phosphate, 1-3 parts of lead stearate, 1-3 parts of calcium stearate, 0.1-0.5 part of stearic acid, 35-45 parts of nitrile rubber, 3-5 parts of modifier, 2-5 parts of tribasic lead sulfate, 1-3 parts of chlorinated paraffin, 1-3 parts of polyethylene wax, 2-5 parts of chlorinated polyethylene and 3-8 parts of light calcium carbonate. The preparation method of the polyvinyl chloride hose comprises the following steps: adding the heat stabilizer, plasticizer, lubricant, modifier and filler into the polyvinyl chloride resin, and carrying out high-speed mixing, granulation, extrusion, cooling for setting, drawing, cutting and detection to prepare the polyvinyl chloride hose. The polyvinyl chloride hose has the characteristics of high temperature resistance, favorable oil resistance, aging resistance, high strength, high toughness, corrosion resistance, long service life and favorable flame retardancy.

Description

technical field [0001] The invention relates to the technical field of PVC pipe production, in particular to a preparation method of a polyvinyl chloride hose. Background technique [0002] As one of the products of scientific and technological development, PVC pipes are readily available in daily life. PVC pipes have the characteristics of light weight, corrosion resistance, high compressive strength, safety and convenience. Polyvinyl chloride hose is made of polyvinyl chloride (PVC) resin. Pure polyvinyl chloride (PVC) resin belongs to a class of strong polar polymers. Its intermolecular force is relatively large, which leads to the softening temperature and melting temperature of PVC. The temperature is relatively high, and generally requires 160-210°C to process; the substituted chlorine groups contained in PVC molecules can easily lead to dehydrochlorination of PVC resin.
