Abstract

The invention relates to the technical field of PE drainage pipes, and discloses a novel PE drainage pipe and production equipment thereof. The novel PE drainage pipe is prepared from the following raw materials in parts by weight: 60-90 parts of high-density polyethylene, 70-95 parts of low-density polyethylene, 3.5-4 parts of white carbon black, 3-7 parts of calcium carbonate, 3-6 parts of nano kaolin, 0.9-1.3 parts of polyacrylamide, 1.2-2.4 parts of a flame retardant, 4-14 parts of zinc oxide, 2-5 parts of an anti-aging agent and 7-10 parts of an antioxidant. According to the novel PE drainage pipe and the production equipment thereof provided by the invention, the flame retardant, the anti-aging agent and the antioxidant are added, so that the antioxidant, flame-retardant and aging-resistant effects are improved, and the PE drainage pipe can be used for a long time; by arranging an electromagnetic heater, energy is saved compared with an old resistance ring; the energy is saved during production.

Description

technical field [0001] The invention relates to the field of PE drainage pipes, in particular to a novel PE drainage pipe and production equipment thereof. Background technique [0002] PE is polyethylene. Generally, the application range of PE pipe water supply pipes is below 40°C, and cannot be used for hot water delivery pipes. PE pipe is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial chemicals. Certain classes of chemicals can cause chemical corrosion, such as corrosive oxidizers (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The drainage pipe is a new type of permeable drainage plastic pipe with a corrugated appearance formed by adding other additives to polyethylene. The permeable corrugated pipe is made by punching holes in the g...
