Silicon rubber wrapped rubber tube using carbon fiber as reinforcing layer and manufacture process thereof

Abstract

The invention relates to a manufacture process of a silicon rubber wrapped rubber tube using carbon fiber as a reinforcing layer. The manufacture process comprises the following steps that: surface treatment is carried out on carbon fiber cloth, and the surface polar group content of the carbon fiber cloth is improved; an inner rubber layer is wound on a mold core in the required dimension; the carbon fiber cloth subjected to the surface treatment is used as the reinforcing layer to be wrapped on the inner rubber layer; an outer rubber layer is wrapped and wound on the surface of the carbon fiber cloth, and a rubber tube is formed; the rubber tube is vulcanized, and finished products are obtained, wherein the inner rubber layer and the outer rubber layer comprise silicon rubber. The carbon fiber cloth is used as the reinforcing layer for manufacturing the silicon rubber wrapped rubber tube, the problems of low intensity and poor pressure resistance capability of the existing rubber tube are solved, in addition, the problem of low temperature resistance performance of the silicon rubber tube using traditional materials such as polyester fiber or glass fiber and the like as the rubber reinforcing layer is solved, and the temperature resistance and pressure resistance performance of the silicon rubber is exerted to the maximum degree. The rubber tube produced by the manufacture process can be applied to the fields of high-power diesel engines, generators and the like with high pressure resistance and temperature resistance requirements.

Description

technical field [0001] The invention relates to a silicone rubber-coated rubber hose with carbon fiber as a reinforced layer and its manufacturing process. It has a new skeleton material and manufacturing process, and has the effects of high temperature resistance, low temperature resistance and pressure resistance. Background technique [0002] The existing silicone rubber-covered hose generally has the problem of low pressure resistance. Because the tensile strength and constant elongation strength of silicone rubber itself is low, it cannot meet the pressure resistance requirements in many occasions. In addition, most of the existing silicone rubber skeleton materials use polyester fibers or glass fibers, among which polyester fibers have low heat resistance, low strength, and are not resistant to acids and alkalis with high concentrations, while glass fibers have poor flex resistance and low density. Therefore, the application range of silicone rubber cannot be fully uti...
