Abstract

The invention discloses a corrosion-resisting pipe for conveying chemicals. The corrosion-resisting pipe is characterized by consisting of the following raw materials in parts by weight: 84-90 parts of pvc (poly vinyl chloride) resin, 6-10 parts of furfural resin, 3-4 parts of diisononyl phthalate, 10-12 parts of acrylonitrile-butadiene-styrene copolymers, 1-2 parts of sodium silicoaluminate, 2-3 parts of bentonite, 2-3 parts of carbon fibers, 0.7-1 part of stannous octoate, 1-2 parts of 1-hydroxyethyl-2-oleic imidazoline, 2-3 parts of oxidized polyethylene wax, and 8-15 parts of composite fillers. The corrosion-resisting pipe has excellent resistance to acid, alkali and corrosion and is not affected by moisture and soil acidity and alkalinity, so that the corrosion-resisting pipe does not need any anticorrosion treatment during pipeline laying.
