High-strength anti-aging underground communication pipe and preparation method thereof

Abstract

The invention discloses a high-strength anti-aging underground communication pipe and a preparation method thereof.The high-strength anti-aging underground communication pipe is prepared from, by mass, 180-220 parts of polypropylene, 20-24 parts of corn starch, 16-20 parts of PPG-n castorate, 14-18 parts of polyvinyl alcohol, 20-24 parts of dimethyl phthalate, 16-20 parts of cobalt acetylacetonate, 14-18 parts of butyl carbitol acet, 16-20 parts of graphite fiber, 14-18 parts of paraffin oil, 20-24 parts of polymethyl acrylate, 16-20 parts of zirconium oxide, 16-20 parts of boron carbide, 14-18 parts of zinc oxide, 20-24 parts of montmorillonoid, 16-20 parts of 1,4-dyhydroxyl sulfanilic acid, 14-18 parts of antimony pentafluoride, 20-24 parts of sodium antimonite, 16-20 parts of furan resin, 14-18 parts of Pulullan, 20-24 parts of sorbitol, 14-18 parts of tetramethrin, 20-24 parts of stearoylbenzoylmethane and 16-20 parts of aluminum dihydrogen phosphate.

Description

technical field [0001] The invention relates to the field of pipe production, in particular to a high-strength anti-aging buried communication pipe and a preparation method thereof. Background technique [0002] Compared with PE pipes, PVC pipes have better tensile and compressive strength, excellent corrosion resistance and lower price. They are suitable as communication pipes, but they are prone to brittleness during use, which affects their service life. In order to ensure the permanence of the toughness of PVC pipes, PVC pipes need to be modified. If only a certain type of elastomer or a certain type of rigid body is used for toughening, it will cause an imbalance in the performance indicators of toughness, stiffness, and elastic modulus. Therefore, it is manufactured It is the main technical problem at present to maintain high strength while resisting impact and cracking, and to have good corrosion resistance. Contents of the invention [0003] The purpose of the pre...
