Problems solved by technology

Usually, a double-roller rubber mixing machine is used for preparation. Due to the shearing action of the rubber mixing machine, after the carbon fiber is cut, its erosion resistance performance decreases. With the development of technology, the material is required to have better erosion resistance and can be produced. The accuracy of the material size needs to be further improved

Abstract

A carbon fiber / phenolic-nitrile rubber material and a preparation method thereof belong to the field of rubber composite material preparation. The material is prepared from the following components by weight: 50-55% of carbon fiber, 18-25% of phenolic aldehyde and 22.5-30% of nitrile rubber. The carbon fiber is weaved by a weft knitting process, and presents double back texture. The density of the material is 1.38 g / cm<3>. The preparation method is as below: calculating the amount of carbon fiber by equation, weaving by using carbon fiber, weighing the knitted fabric, determining the amount of phenolic and nitrile rubber according to the density, dissolving nitrile rubber and phenol, adding carbon fiber for gumming, and then drying to obtain the desired material. The carbon fiber / phenolic-nitrile rubber material provided by the invention can significantly improve the resistance to erosion, and has high ductility.

Description

technical field [0001] The invention belongs to the field of rubber composite material preparation, and in particular relates to a carbon fiber / phenolic-acrylonitrile-butadiene rubber material and a preparation method thereof. Background technique [0002] Carbon fiber / phenolic-nitrile rubber material is a carbon fiber-reinforced modified phenolic rubber-based composite material, which is an anti-scour layer material for engines. Usually, a double-roll rubber mixing machine is used for preparation. Due to the shearing action of the rubber mixing machine, after the carbon fiber is cut, its erosion resistance performance decreases. With the development of technology, the material is required to have better erosion resistance and can be produced. The accuracy of material size needs to be further improved. Contents of the invention [0003] The invention provides a carbon fiber / phenolic-acrylonitrile-butadiene rubber material and a preparation method thereof, so as to...
