Abstract

The invention relates to a strength reinforced and antifriction ultrahigh molecular weight polyethylene composite material. The composite material comprises ultrahigh molecular weight polyethylene and superfine inorganic powder. The composite material adopts the coupling agent processed superfine inorganic powder for filling, and is prepared through solid phase grafting technology, thereby obviously improving the compatibility of components and functionally modifying the surface of the composite material. The solid phase grafting technology has little solvent consumption, simple production equipment, convenience for the industrialized production, and good development prospect.

Description

A reinforced anti-friction ultra-high molecular weight polyethylene composite material technical field The invention relates to the polymer composite material industry in the field of chemical industry, in particular to an ultra-high molecular weight polyethylene composite material and a preparation method thereof. Background technique Ultra-high molecular weight polyethylene (hereinafter referred to as UHMWPE) is a polyethylene with a viscosity average molecular weight of more than 1.5 million. It is a type of polyethylene with incomparable wear resistance, impact resistance and low temperature resistance, etc. Engineering thermoplastics with excellent properties. But it also has its own inherent defects, such as low heat distortion temperature, poor surface hardness, poor abrasive wear and fatigue wear resistance, large dimensional shrinkage, etc. In many aspects, it cannot meet the actual needs of customers. Therefore, it is necessary to use new technology to modify UH...
