Abstract

The invention discloses a continuous carbon fiber winding composite reinforced MPP electric power pipe and a preparation method thereof. The continuous carbon fiber winding composite reinforced MPP electric power pipe comprises an inner pipe, an insulating layer, an outer pipe and a carbon fiber layer, the insulating layer is arranged between the inner pipe and the outer pipe, the outer surface of the outer pipe is wrapped by the carbon fiber layer, and the outer pipe is prepared from, by weight, , 60-80 parts of isotactic polypropylene resin, 5-10 parts of block copolymerized polypropylene, 3-5 parts of olefin block copolymerized elastomer OBC, 0.5-2 parts of heat-resistant insulating orange master batch and 10-20 parts of ultra-high molecular weight polyethylene resin. The inner pipe is prepared from, by weight, 50-65 parts of modified polypropylene, 3-4 parts of a compatilizer, 2-3 parts of a stabilizer and 1.5-3 parts of a flame retardant, the inner pipe is obtained through extrusion of an extruder, the outer layer of the inner pipe is coated with waterproof glue so that the insulating layer can be bonded, the outer surface of the insulating layer is covered with the outer pipe, the carbon fiber layer is wound on the surface of the outer pipe through a carbon fiber winding machine, and a finished product is obtained.

Description

technical field [0001] The invention relates to the technical field of electric power pipes, in particular to a continuous carbon fiber winding composite reinforced MPP electric power pipe and a preparation method thereof. Background technique [0002] Carbon fiber refers to high-strength and high-modulus fibers with a carbon content of more than 90%. The excellent material is a special fiber composed of carbon elements. Carbon fiber has the characteristics of high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance. The shape is fibrous, soft, and can be processed into various fabrics. Axis preferred orientation, so it has high strength and modulus along the fiber axis direction. In addition, the density of carbon fiber is small, so the specific strength and specific modulus are high; the main use of carbon fiber is as a reinforcing material and resin, metal, ceramics and carbon. and other composites to manufa...
