Problems solved by technology

[0006] In order to solve the unsatisfactory performance of the existing plastics used to prepare pipes in terms of corrosion resistance and heat resistance, it is used in the discharge and transportation of acid and alkali liquids, the hot gas transportation of heating pipelines and the transportation of agricultural irrigation pipelines in various industrial devices Among them, it is easy to be affected by corrosion and thermal oxidation, which leads to a faster aging of the pipeline, and it is very easy to leak after long-term use. However, the pipeline is usually distributed underground, and the replacement of the pipeline is cumbersome and has a long cycle. Corrosion-resistant and heat-resistant modified plastic with good chemical resistance and high temperature resistance prepared for special pipes

Description

technical field [0001] The invention relates to the field of plastics, in particular to a corrosion-resistant and heat-resistant modified plastic with good chemical reagent resistance and high temperature resistance, which is used in the preparation of special pipelines, and a preparation process thereof. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. [0003] However, the existing plastics used to prepare pipes ar...
