Problems solved by technology

[0002] Double-wall corrugated pipe is a new type of pipe with a corrugated outer wall and a smooth inner wall. It has been widely used in sewage discharge in municipal engineering. The material for making double-wall corrugated pipes is mainly polyvinyl chloride (PVC) and high-density Polyethylene (HDPE), and HDPE double-wall corrugated pipes are widely used due to their good corrosion resistance and surface structure. At present, HDPE double-wall corrugated pipes should not be too thick for installation convenience and cost reduction, but With the increase of the diameter of the double-wall corrugated pipe, its ring stiffness and other properties continue to decline, so the risk of use is greater. If the material ratio of the HDPE double-wall corrugated pipe can be optimized so that the material has better mechanical properties To effectively solve such problems, we provide an enhanced HDPE double-wall corrugated pipe and its preparation method

Abstract

The invention discloses a formula of a reinforced HDPE double-wall corrugated pipe. The formula comprises, by weight, 280 parts of high density polyethylene, 80 parts of chopped glass fibers, 8 parts of elastomer, 12 parts of phenolic resin, 30 parts of wood powder, 8 parts of a coupling agent, 10 parts of calcium carbonate, 10 parts of nanometer silicon oxide, 1 part of an antioxidant, 26 parts of methylsilicone oil and 4 parts of a lubricant. A manufacturing method of the reinforced HDPE double-wall corrugated pipe comprises the following steps: wood powder processing, plasticizing treatment, batch mixing, granulation and compression molding. The reinforced HDPE double-wall corrugated pipe has the advantages of good rigidity and strength, low creep deformation ratio and good impact performance, so the use amount of materials is effectively reduced on the premise of guaranteeing the use performances of the pipe, thereby the cost is saved, and the pipe has very high practical values.
