Abstract

The invention provides a wear-resistant heat-resistant polyolefin composite material and a preparation method thereof. The wear-resistant heat-resistant polyolefin composite material is prepared from,by mass, 100 parts of a resin matrix, 5-45 parts of diatomaceous earth, 0.1-0.5 part of a coupling agent, 0.1-0.5 part of an antioxidant, 0.2-1 part of a heat stabilizer and 0.2-1 part of a lubricant. The prepared polyolefin composite material has the advantages of wear resistance, heat resistance, dimensional stability and the like and is endowed with certain functionality on the basis of the modification of traditional engineering plastic. In addition, the equipment and process required for preparing the composite material are simple, and large-scale production can be directly achieved.

Description

technical field [0001] The invention provides a wear-resistant and heat-resistant polyolefin composite material and a preparation method thereof, belonging to the field of modification of engineering plastics. Background technique [0002] Polyolefin materials, as the most commonly used engineering plastics, are increasingly in special demand in end applications. Blending modification is one of the commonly used modification methods for polyolefin materials. Usually, a certain substance is used as the modified material to endow the polyolefin matrix material with certain special characteristics through the process of melting, blending and dispersion. [0003] At present, the modification work of polyolefin materials has certain deficiencies in terms of material wear resistance and heat resistance, especially for the application of functional parts, the demand for wear resistance is particularly strong. In addition, polyolefin-modified composite materials still have shortcom...
