Abstract

The invention discloses a preparation method of a high elasticity plastic hose. The preparation method comprises the following steps: mixing molybdenum disulfide, strontium titanate, zinc dialkyl dithiophosphate and distilled water and heating the mixture, and adding triphenyl phosphite to insulate and stirring the mixture to obtain a primary mixed solution; mixing and stirring polypropylene, a thermoplastic polyurethane elastomer, glycerol tristearate and polyethylene terephthalate at a high temperature to obtain a primary reaction material; adding polyimide fibers into the primary mixed solution to be uniformly mixed and then adding paraffin for ultrasonic dispersion to obtain a secondary mixed solution; and then mixing the primary reaction material with the secondary mixed solution in vacuum, then jointly adding the vacuum mixed blank, a stabilizer, a plasticizer and an anti-static agent into a granulator to be granulated, then inputting the mixture into a charging barrel of the extruder, inputting the mixture which is extruded by the extruder into an injection molding machine for injection molding to obtain a product plastic hose. The prepared high elasticity plastic hose is high in elastic deformation resistance, and has a good application prospect in water supply and sewerage works.

Description

technical field [0001] The invention relates to the technical field of plastic hose manufacturing, in particular to a preparation method of a high-elasticity plastic hose. Background technique [0002] Plastic pipes have the advantages of light weight, high strength, simple manufacturing methods, low economic cost, convenient processing and use, corrosion resistance, and long life. The main application pipe. As an important part of the field of new chemical materials, the research and development of modified plastic pipes has become one of the key scientific and technological fields. In the past, in the plastic hose market, the main materials used were polyvinyl chloride resin and rubber materials. With the development of plastic technology and processing equipment, polyethylene (PE), thermoplastic elastomer (TPES), thermoplastic polyurethane (TPUS), Thermoplastic polyolefin (TPOS) and thermoplastic alloy material (TPVS) appear in large quantities in the plastic hose marke...
