Problems solved by technology

[0004] Although polycarbonate is superior in various properties, various problems will appear in the process of use after preparation and molding. Therefore, adding various auxiliary components to polycarbonate to further improve its performance is an important measure in actual production. Polycarbonate After carbonic acid ester is prepared into plastic pipes, in the process of application in various fields, it is easy to be limited by the use time and the use environment, causing the plastic pipes to crack, which seriously affects the service life of plastic pipes. Therefore, it is the current stage to improve the crack resistance of plastic pipes. An important research and development direction

Abstract

The invention provides an anti-cracking plastic pipe and a preparation method thereof and relates to the technical field of plastic pipe processing. The anti-cracking plastic pipe is prepared from thefollowing raw materials: polycarbonate, phenolic resin, low density polyethylene, dodecanedioic acid diester, bisphenol A cyanate ester, o-chlorophenyl isocyanatecarbon, carbon fiber, nano silicon dioxide, ethyl cellulose, a compatilizer, diphenyl methane diisocyanate, hexamethyl phosphoryl triamine, a composite antioxidant, epoxy ethane, castor oil, a plasticizer and gamma-aminoethyl aminopropyltrimethoxysilane. The preparation method mainly comprises steps of base material mixing, raw material pretreatment, auxiliary material treatment, booster mixing, mixing and forming, and the like. Byadopting the anti-cracking plastic pipe, defects of the prior art can be overcome, the anti-oxidation performance of the plastic pipe can be improved, the plastic pipe can be prevented from cold and heat cracking, the mechanical properties of the plastic pipe can be improved, and the service life of the plastic pipe can be prolonged.

Description

technical field [0001] The invention relates to the technical field of plastic pipe processing, in particular to a crack-resistant plastic pipe and a preparation method thereof. Background technique [0002] Polycarbonate is a resin material with good insulation, good extensibility, chemical corrosion resistance, high temperature resistance, severe cold resistance, flame retardancy and impact resistance. It is the most commonly used general engineering plastic in daily life. [0003] Usually, polycarbonate is prepared into plastic tubes and used in various decorative craft container industries such as transparent grease guns, bird feeders, wine cannons (draft beer machines), cup removers, as well as traffic batons (hand-held induction lights), garden lights, Lawn lamps, LED fluorescent lamps, cabinet lamps, landscape lamps, work lighting and other lighting and lighting industries are also widely used in various industrial transparent protection tube industries such as wire t...
