Abstract

The invention discloses a wear-resisting high-temperature-resistant high molecular material formula. The material is prepared from the following raw materials in parts by weight: 100 parts of ultra high molecular weight polyethylene, 2 to 3 parts of graphene, 3 to 4 parts of talcum powder, 1 to 2 parts of glass beads, 2 to 5 parts of silicon dioxide and 4 to 5 parts of accessory ingredient. According to the formula provided by the invention, the raw materials including the graphene, the talcum powder, the glass beads, the silicon dioxide and the like are used for performing reinforcing and modifying treatment on the ultra high molecular weight polyethylene to improve the mechanical performance of the same, the prepared material does not only have the own excellent performance of the ultra high molecular weight polyethylene, and the indexes of hardness, toughness, high-temperature resistance, wear resistance and the like of the prepared material are all improved, devices for a pump and a valve made from the modified ultra high molecular weight polyethylene material are long in service life and safe and reliable in fireproof performance.

Description

technical field [0001] The invention relates to a formula, in particular to a wear-resistant and high-temperature-resistant polymer material formula. Background technique [0002] Ultra-high molecular weight polyethylene material has excellent performance characteristics such as super wear resistance, self-lubrication, relatively high strength, stable chemical properties, and strong anti-aging performance. It is mainly used as a diaphragm, seal, and sealing friction pair in pump valves. However, in the actual application process, ultra-high molecular weight polyethylene materials have shortcomings such as large linear expansion coefficient, poor dimensional stability, poor thermal conductivity, easy cold flow, and difficult molding, which make them defective during use. Seriously affect the performance of pumps and valves. Ultra-high molecular weight polyethylene is a high-molecular compound, which is difficult to process, and has super wear resistance, self-lubrication, hig...
