Problems solved by technology

[0006] However, the inorganic anti-wear agent as a dispersed phase is divided into the continuous phase of the matrix resin, and the area of ​​the matrix resin on the stressed section is smaller than that of the pure matrix resin material, so the tensile strength of the filling system generally decreases; when the dispersed phase filler When it is a rigid particle, because it cannot be deformed under stress, it cannot terminate cracks or produce silver crazes to absorb impact energy, which often leads to a decrease in the toughness of the filling system

Abstract

The invention discloses a composition for producing an oil-free lubrication engineering machinery sliding block. The composition comprises amide monomer, abrasion-resistant agents, flexibilizer, catalyst and activating agents, wherein the abrasion-resistant agents are selected from one or mixer of PTFE(Polytetrafluoroethylene) micro powder, grease, graphene, melamine urea complex and organic silicone powder. The oil-free lubrication engineering machinery sliding block produced by the composition greatly increases abrasion resistance on the basis of ensuring the mechanical property of materials, and has wide application prospect.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a composition for preparing an oil-free lubrication engineering machinery module. The present invention also relates to an oil-free lubricating construction machinery module prepared from the composition. Background technique [0002] In the construction machinery industry, cast nylon sliders are widely used, but ordinary nylon is often difficult to meet some special technical requirements, and its dimensional stability and wear resistance are not good when the load is heavy. With the development of the construction machinery industry, the requirements for lightweight equipment are getting higher and higher, and the application range of cast nylon in the construction machinery industry is also becoming wider and wider. Cast nylon material has high mechanical strength and toughness, and has the advantages of light weight and low friction coefficient. It has been widely used i...
