Embodiment 1

[0016] According to the proportion by weight, its composition is: 25 parts of anti-corrosion and wear-resistant polyvinyl chloride particles with a particle size of 2 mm, and 75 parts of ceramic particles with a particle size of 0.5 mm. Stir and mix the two uniformly and heat to 160 degrees Celsius. At this time, the mixture is in a semi-melted state, heated and put into the mold, and pressed on a press for 8 minutes to form a ceramic plastic wear-resistant and anti-corrosive composite pipe.

Embodiment 2

[0018] According to the proportion by weight, its composition is: 15 parts of anti-corrosion and wear-resistant PTFE particles with a particle size of 3 mm, and 50 parts of ceramic particles with a particle size of 5 mm. Stir and mix the two evenly and heat to 180 degrees Celsius At this time, the mixture is in a semi-melted state, heated and put into the mold, and pressed on the press for 10 minutes to form a ceramic plastic wear-resistant and anti-corrosive composite pipe.

Embodiment 3

[0020] According to the proportion by weight, its composition is: 72 parts of 5 micron ceramic particles, 25 parts of liquid polyurethane rubber, mix the two evenly, then add 3 parts of diphenylmethane diisocyanate curing agent to the mixture, and further stir Mix uniformly, cast and mold, heat to 150 degrees Celsius, heat preservation for 2 hours to make ceramic rubber wear-resistant and anticorrosive composite pipe.

Abstract

The invention provides a ceramic polymer-material wear-resistant anticorrosion composite pipe and a manufacturing method thereof. The composition proportioned in portion by weight of the composite pipe is 10 to 50 portions of polymer material and 30 to 90 portions of ceramic particles. The polymer material and the ceramic particles are mixed well, heated to between 50 and 250 DEG C and prepared into the ceramic polymer-material wear-resistant anticorrosion composite pipe. The polymer material is a mixture of one or two types of anticorrosion plastics or rubber. The invention solves the deficiency that single-material and steel-plastic delivery pipelines in the prior art cannot meet the requirements of bearing certain pressure and wear and resisting strong corrosion. The invention has the advantages of utilizing the high hardness, good corrosion resistance and wear resistance of ceramics and the good corrosion resistance, good toughness and impact resistance of plastics or rubber to manufacture the pipelines with ceramic-plastic, ceramic-rubber and ceramic-rubber-plastic composite materials so as to ensure that the pipelines have good wear-corrosion resistance and good toughness andimpact resistance, thereby greatly reducing use cost and ensuring more extensive use.

Description

Technical field [0001] The invention relates to a ceramic polymer composite material, a tubular product and a forming method thereof, in particular to a ceramic rubber, ceramic plastic and ceramic rubber-plastic wear-resistant and anticorrosive composite pipe and a manufacturing method thereof. Background technique [0002] In industries such as mining, metallurgy, building materials, coal, electric power, and environmental protection, the transportation of materials is carried out long-distance and powerfully through pipelines. The conveying pipe not only bears considerable pressure, but also suffers from severe abrasion. The conveyed materials are often highly corrosive. A single-material pipe cannot meet the requirements, and a composite pipe must be used. At present, composite pipes are mainly divided into two categories: steel-plastic composite pipes and bimetallic pipes. Steel-plastic pipes are not corrosion-resistant, and bimetallic pipes have better wear-resistance perfo...
