Abstract

The invention relates to an ultrahigh molecular polyethylene composite material in the technical field of engineering plastics, in particular to a circular nanometer composite material and a production method thereof. The production method comprises the following steps of: fully mixing ultrahigh molecular polyethylene, conductive carbon black, a red phosphorus flame retardant agent, graphite powder, boron carbide and molybdenum disulfide according to weight ratios of 100:1.6-2.4:8-12:1.8-2.2:0.8-1.2:1.0-2.0, heating, drying, processing the materials into nanometer-shaped particles, placing the nanometer-shaped particles into a mould, rising temperature to be 200 DEG C and forming; and then cooling, increasing pressure to 30 Mpa, maintaining the pressure for 1h-2h, and demoulding and trimming after decompression; the circular nanometer composite material of the invention is a novel lining board synthetic material and has the advantages of high cost performance, wide applicable scope, very high wear-resisting property, excellent lubricity, impact resistance, low frictional coefficients and good flame retarding and antistatic performance; and the production method has the advantages of scientific formulation, strict process and wide market prospect.

Description

technical field [0001] The invention relates to an ultrahigh molecular polyethylene composite material in the technical field of engineering plastics, and relates to a ring-nano composite material and a production method thereof. Background technique [0002] Ultra-high molecular weight polyethylene wear-resistant liner has low density, light weight, and a density between 1.0 and 1.1. It is an ideal product for plastic to replace steel, and has achieved good results in the application of silo lining boards and special-shaped parts in steel, electric power, coal, cement and other industries. With the development of society, polymer lining boards cannot meet the requirements of special industries in many aspects, are not strong in high temperature resistance, have no flame retardancy and antistatic properties, and the above-mentioned lining boards are no longer suitable for use in many fields. The preparation technology of ring-nano composite liner perfectly combines the rigi...
