Abstract

The invention discloses a lightweight high-strength carbon fiber graphene plastic pipe. The plastic pipe is prepared by the following raw materials by weight: 80-90 parts of polyvinyl chloride, 10-20parts of carbon fiber, 15-20 parts of carbon fiber intercalated graphene composite material, 8-12 parts of modified calcium carbonate, 0.5-1 part of acrylate, 0.8-1.5 parts of zinc stearate, 1-2 partsof antioxidant, 0.8-1.5 parts of lubricant and 0.5-1 part of stabilizer. The plastic pipe is formed by preparation of the carbon fiber; preparation of the carbon fiber intercalated graphene compositematerial; material mixing and extrusion molding. The preparation process is reasonable in design, simple, practical, not only suitable for large-scale industrial production of the plastic pipe, but also capable of ensuring high-performance quality of the plastic pipe, thereby being widely applicable to the fields of water supply and drainage systems, heating pipeline systems and gas transportation systems.

Description

technical field [0001] The invention relates to the field of plastic pipes, in particular to a lightweight and high-strength carbon fiber graphene plastic pipe. Background technique [0002] Plastic pipes are generally made of synthetic resin, that is, polyester, added with stabilizers, lubricants, plasticizers, etc., and extruded in a pipe making machine by a "plastic" method. Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, plastic pipes are light in weight, have good corrosion resistance, save metal materials, and have low economic costs. The smooth inner wall of plastic pipes reduces the resistance of fluid delivery. It has the advantages of convenient transportation and long service life. Therefore, plastic pipes have attracted the attention of pipeline engineering, and plastic pipes have become the main pipe materials used in the fields of urban construction, building water supply and drainage, urban electrical transmiss...
