Abstract

The invention discloses a wear-resistant, high-strength and light-weight poly (ether-ether-ketone) composite material. The poly (ether-ether-ketone) composite material comprises the following raw materials in parts by weight: 71-83 parts by weight of poly (ether-ether-ketone) resin, 5-10 parts by weight of suspension polytetrafluoroethylene resin, 7-12 parts by weight of carbon fiber powder and 5-7 parts by weight of aluminum oxide powder, as well as a silane coupling agent with the adding quantity of 0.8-1.5% of the weight of the aluminum oxide powder. The poly (ether-ether-ketone) composite material disclosed by the invention has the performance characteristics of wear resistance, high strength, self-lubrication, light weight, corrosion resistance and the like, is used for replacing a hard alloy and a metal framework to assemble a novel sliding bearing, effectively reduces the cost and weight of a bearing product (the weight is reduced by 30%) under the situation of meeting the requirements for service life, and can obviously reduce the power consumption and noise of a pump and achieve the purposes of saving energy and reducing consumption.

Description

1. Technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a wear-resistant, high-strength, light-weight polyetheretherketone composite material, which is used as a wear-resistant material in a novel sliding bearing instead of hard alloy. 2. Background technology [0002] At present, the sliding bearings used in multistage centrifugal pumps are assembled with cemented carbide as the wear-resistant material embedded on the metal frame, with long service life and relatively stable performance. However, due to the high price of cemented carbide, the sliding bearing is used as an auxiliary bearing in the multistage centrifugal pump, and the quantity is large, so the cost of bearing accessories is too high, and the density of cemented carbide is high, which increases the weight of the equipment and reduces the pump power. The consumption and noise are also significantly increased. In the current situation of energy saving and...

Problems solved by technology

However, due to the high price of cemented carbide, the sliding bearing is also used as an auxiliary bearing in a multistage centrifugal pump, and the number is large, so the cost of bearing accessories is too high, and the density of cemented carbide is high, which increases the weight of the equipment and reduces the pump power. The consumption and noise are also significantly increased. Under the current requirement of saving energy and reducing consumption and further reducing the cost of pump products, there is an urgent need for a wear-resistant, high-strength, light-weight new material to replace cemented carbide, and to make sliding pumps that meet the requirements of use. Bearing products

[0003] The polyether ether ketone composite material with ordinary formula has the characteristics of high strength, self-lubrication, and low density, which can meet the basic performance requirements of multi-stage centrifugal pump sliding bearings, and the density is one tenth of that of cemented carbide materials, which can effectively reduce The weight of the accessories and related costs of the equipment, but its poor particle wear resistance and limited service life in media containing fine sand and other solid particles limit its application in the field of multistage centrifugal pumps
