Abstract

The invention discloses a preparation method of an anti-radiation plastic hose material. The preparation method comprises the steps that low density polyethylene and melamine formaldehyde resin are subjected to ultrasonic treatment and separated in mixed acid, hydroxyethyl cellulose is subjected to ultrasonic treatment and diluted with ammonium ethoxylated alkyl sulfate and hexamethylcyclotrisiloxane after being treated through sulphuric acid, cobalt carboxy-boro aceglate and sodium hexametaphosphate are mixed, then acrylic acid, tetramethoxysilane and maleic anhydride grafted polyethylene areadded in batches, the product is mixed, dewatered and solidified, a preliminary blank is obtained, pentaerythritol stearate and phenolic resin are modified to obtain a modified mixture, finally the preliminary blank and the modified mixture are stirred, dehydrated, extruded and cooled with perlite micropowder after being subjected to banburying, and the finished product of plastic hose material is obtained. The bending strength and the tensile strength retention rate of the prepared anti-radiation plastic hose material are high after the anti-radiation plastic hose material is radiated, and the anti-radiation plastic hose material has the good application prospect in the hose manufacturing industry.

Description

technical field [0001] The invention relates to the technical field of hose manufacture, in particular to a preparation method of a radiation-proof plastic hose material. Background technique [0002] Because of its high mechanical strength, plastic hoses are not easily corroded by acids and alkalis, and are widely used in water pipes, gas pipes, etc., and are also used in the medical field. 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 market as a new generation of materials. The processing performance of these new materials is more superior, showing good substitution. At present, some high-performance thermoplastic elastomers and nyl...
