High-hardness plastic tube

Abstract

A disclosed high-hardness plastic tube is prepared from the following raw materials in parts by weight: 30-60 parts of polyvinyl chloride resin, 6-10 parts of aluminium hydroxide, 6-11 parts of bisphenol A phosphite, 6-9 parts of flint clay powder, 5-9 parts of graphite powder, 6-9 parts of polytetrafluoroethylene wax, 4-8 parts of bamboo charcoal powder, 5-10 parts of N,N-diethylaniline, 2-5 parts of triclocarban, 4-12 parts of disodium methylenebisnaphthalenesulphonate, 5-8 parts of calcium phosphate, and 3-5 parts of polyethylene glycol fatty acid ester. The provided high-hardness plastic tube possesses relatively high hardness and tensile strength, is resistant to high temperature, is not easy to combust, and is excellent in impact strength, wear resistance, ring stiffness and other performances, high in comprehensive performance and good in stability.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-hardness plastic pipe. Background technique [0002] The structure of PVC reinforced hose is generally: inner layer, fiber reinforced interlayer, and outer layer. The characteristics of this reinforced hose are: good pressure resistance, strong tensile strength, good corrosion resistance, small quality, and low price. The cost performance is generally better than that of pure PVC hoses, fire hoses, etc. It is widely used in fields such as farmland irrigation and the transportation of fluid media in the food industry. However, the research work on the formulation design of inner and outer pipes has not been satisfactory for a long time , the performance in its mechanical properties or other aspects is not very good. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to ...
