Embodiment 1

[0019] Attached below figure 1 The extruded silicone rubber hose with carbon fiber as reinforcement layer and its manufacturing process will be described in detail.

[0020] A manufacturing process of silicone rubber extruded rubber hose with carbon fiber as a reinforced layer, comprising the following steps: extruding a layer of inner rubber layer 2 on a mold core 1 of required size; performing surface treatment on carbon fiber cloth 3 to improve its surface polarity The content of the group; weave or wind the surface-treated carbon fiber cloth 3 as a reinforcement layer on the inner rubber layer 2; extrude a layer of outer rubber layer 4 on the carbon fiber cloth 3, and wrap it on the surface of the carbon fiber cloth 3; molding After completion, the obtained rubber hose is vulcanized to obtain a finished product, wherein the inner rubber layer and the outer rubber layer include silicone rubber. Preferably, according to different requirements, this composite mode can be imp...

Embodiment 2

[0025] This embodiment provides a preferred technical process for bonding carbon fiber cloth 3 to silicone rubber. The surface of the carbon fiber cloth 3 is treated through a certain process, so that it has good bonding performance and adhesion strength with the silicone rubber. Because the carbon fiber cloth 3 without surface treatment has a small content of carbonyl, carbonyl and other polar groups on the surface, which is not conducive to bonding with the matrix material, its surface is chemically inert, and is not easy to infiltrate or chemically react with the matrix material. Therefore, in order to realize the load transfer between rubber and fiber, give full play to the reinforcing effect of carbon fiber, and improve the mechanical properties and temperature resistance of composite materials, the surface of carbon fiber must be treated. Preferably, the specific treatment process of this embodiment is as follows: firstly, with NH 4 HCO 3 As an electrolyte, a current (...

Abstract

The invention discloses a manufacturing technique of a silicon rubber extrusion rubber tube utilizing a carbon fiber as a reinforcement layer, which comprises the following steps of: extruding an inner rubber layer on a mould core with required dimension; performing surface treatment on the carbon fiber cloth to improve the content of a surface polar group thereof; weaving or winding the carbon fiber cloth with treated surface on the inner rubber layer as the reinforcement layer; extruding an outer rubber layer on the carbon fiber cloth to wrap the surface of the carbon fiber cloth; vulcanizing the obtained rubber tube after the forming procedure to obtain a finished product, wherein the inner rubber layer and the outer rubber layer comprise silicon rubber. According to the invention, the carbon fiber cloth is used as the reinforcement layer to manufacture the silicon rubber coated rubber tube, thereby not only solving the problems of low strength and bad pressure resistance of the current silicon rubber tube, but also improving the temperature resistance of the silicon rubber tube and playing the temperature and pressure resistance of the silicon rubber to the utmost. The rubber tube produced in the invention can be applied in such fields with high pressure and temperature resistance demands as high power diesel engines and generators, etc.

Description

technical field [0001] The invention relates to a silicone rubber extruded 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] Existing silicone rubber extruded hoses generally have the problem of low pressure resistance. Due to the low tensile strength and constant elongation strength of silicone rubber itself, 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 utiliz...
