Problems solved by technology

[0004] It is a common practice in this field to install a layer of corrosion-resistant material on the outer surface of a new material pipeline. However, due to technical limitations, the strength of this corrosion-resistant material in this field cannot reach the standard, and the service life is not very long. Meet the requirements that pipelines in this field need to meet

Abstract

The invention provides a preparation method of an anti-corrosion pipe material. The method comprises the following steps of a, mixing polyvinyl chloride resin, nitrile rubber and polybutylene resin; feeding the mixture into a mixing machine for mixing; obtaining a first material; b, mixing the first material with modified glass fiber, silicon dioxide and compatilizers; guiding the mixture into a stirring machine; performing high-speed stirring; then, adding semi-refined paraffin wax, asbestos powder and antioxidants; performing uniform mixing; then, performing ultrasonic wave processing to obtain a second material; c, mixing modified nanometer carbon fiber and auxiliary filling materials; feeding the mixture into a ball mill for grinding and stirring to obtain a third material; d, mixing the first material, the third material, a toughening agent, a mildew preventive and a lubricating agent into a single-screw extruding machine; performing extrusion to obtain a pre-finished product; e,guiding the pre-finished product into a mold; performing heating and pressurization; then, performing molding and shaping. The prepared pipeline material has the characteristics of good impact performance, good anti-corrosion performance and high pressure-resistant intensity.

Description

technical field [0001] The invention belongs to the technical field of pipeline materials, and in particular relates to a preparation method of corrosion-resistant pipeline materials. Background technique [0002] Pipes have a wide range of uses. Most of the existing pipes are processed from a single material. The pipes need to bear a certain pressure during use. The pipes are laid at the bottom of the ground. If they are damaged, it will be troublesome to replace them. The traditional pipes are easy to structure inside and block the pipes. , especially for water pipes, bacteria are easy to breed inside the pipe fittings, which affects the quality of water and also corrodes the pipes. [0003] The corrosion resistance of existing pipeline materials is not high, and corrosion-resistant materials are used in various fields such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electric power, military industry, etc. The...
