Abstract

A masterbatch of a bending-resistant highly pressure-bearing corrugated tube and a preparing method thereof are disclosed. The masterbatch comprises polybutylene resin, PA66 resin, biogas mud, butylmercaptooxo stannane, chitosan, tributyl phosphate, polyacrylonitrile, molybdenum sulfide, polyaluminium chloride, triethyl acetyl citrate, tantalum powder, white charcoal powder, oxidized polyethylene wax, a titanate coupling agent KR-38S, zinc stearate and maleic anhydride according to weight parts. The ring rigidity of the corrugated tube prepared from the masterbatch is 13.5-14.6 KN/m2, the bending strength of the corrugated tube is 27-34 MPa, the corrugated tube after a flattening deformation test is free of cracks, and the corrugated tube has excellent comprehensive performance, and improves performance disadvantages of traditional corrugated tube materials.

Description

Technical field [0001] The invention belongs to the technical field of materials, and specifically relates to a bend-resistant high-pressure-bearing corrugated pipe master batch and a preparation method thereof. Background technique [0002] The bellows is a cylindrical thin-walled elastic shell with transverse corrugations, which has the functions of conversion, compensation, connection and energy storage. Compared with pipes made of the same material, corrugated pipes have the advantages of light weight, beautiful appearance, durability, low cost, and good elasticity. They play an irreplaceable role in the fields of medium transmission, power threading, machine tools, and home appliances. [0003] The materials of traditional corrugated pipes are mainly PE, PP or PA, and the performance of corrugated pipes made of different materials is not the same. As the application range of corrugated pipes becomes wider and wider, the performance requirements of corrugated pipes are getting...
