Problems solved by technology

However, at present, ordinary polyethylene hoses still have great shortcomings in wear resistance, and often cannot meet the needs of long-term use when used in some environments involving frequent wear and tear, which also gives polyethylene hoses further development. Development has brought no small constraints

Embodiment 1

[0023] (1) Mix 85% by weight of nitric acid solution and glacial acetic acid in a ratio of 1:25, and stir evenly. Add 55 parts of high-density polyethylene and 36 parts of polyvinyl butyral ester to 1000 parts of the above-prepared mixed solution. In a constant temperature water bath at 80°C, ultrasonically oscillate at a power of 150W for 80 minutes, add 10 times the weight of the system to dilute deionized water, keep it warm and stand still. After the solution is stratified, the supernatant is discarded and the precipitate is pumped. Filter cake is obtained after filtration;

Abstract

The invention discloses a preparation method of a plastic flexible pipe material with strong wear resistance. The method comprises the steps: performing ultrasound and separation on high density polyethylene and polyvinyl butyral in mixed acid; treating hydroxyethyl cellulose by sulphuric acid and performing ultrasound and dilution on the treated hydroxyethyl cellulose with ethyl 3-ethoxypropionate and nano carbon sol; mixing magnesium hydroxide with calcium bisulfate and adding acrylic acid, methyl trichlorosilane and stannic maleate in batches; mixing products and dewatering and curing to obtain primary blank; modifying tris(nonyl phenyl) phosphate and polyglycerol ricinoleate to obtain a modified treatment mixture; finally, smelting the primary blank and the modified treatment mixture,stirring with perlite micropowder and dewatering, extruding and cooling to obtain a finished-product plastic flexible pipe material. The prepared plastic flexible pipe material with the strong wear resistance has excellent wear resistance and a good application prospect in the flexible pipe manufacturing industry.

Description

Technical field [0001] The invention relates to the technical field of hose manufacturing, in particular to a method for preparing a plastic hose material with strong wear resistance. Background technique [0002] Because plastic hoses have the advantages of corrosion resistance, non-leakage, anti-scaling, long service life, etc., market applications and application fields are growing rapidly. At present, the consumer market for plastic hoses at home and abroad is mainly divided into four application areas: daily consumption and health care, hydraulic transmission systems in industry, automobile manufacturing and maintenance, and water conservancy projects. As far as the varieties of plastic hoses are concerned, the polyethylene market is currently growing the fastest, and it is becoming the second largest variety of plastic hoses after polyvinyl chloride. The main reasons for the rapid growth of polyethylene plastic hoses are: polyethylene hoses have very good poly-softness, an...
