Embodiment 1

[0031] Lay a 0.1mm thick polyester fiber cloth on the test bench, evenly brush the water-based epoxy resin with a ratio of 1:20 on the fiber cloth, and dry it at room temperature for 30 minutes. Brush evenly with resorcinol-formaldehyde-latex (RFL adhesive) and dry for 2 minutes. Put the fiber cloth coated with glue flat on the preformed tooling, press it through the pressure plate, and then lightly lock it with the hexagon socket head screw and the compression spring, so that it has tightness in the vertical direction and can be tight in the horizontal and vertical directions. The amount of displacement, and then apply the vertical compression force through the pressure head tooling, so that the fiber cloth skeleton material has the specific "several" shape of the sealing template.

[0032] Gently move the formed skeleton material into a mold with a preheating temperature of 80°C, and then pre-embed a 0.05mm thick film, apply a pressure of 2000MPa through the vulcanizing mach...

Abstract

The invention provides a fiber reinforced rubber sealing diaphragm forming method and equipment thereof, and belongs to the technical field of rubber sealing diaphragm forming, and the method comprises the following steps: S1, uniformly infiltrating polyester fiber cloth with an adhesive, uniformly roll-coating the polyester fiber cloth on framework material fiber cloth, and naturally drying at room temperature; s2, a clamping device is arranged on the forming tool, so that the polyester fiber cloth has certain tightness in the horizontal direction and has displacement in the vertical direction, the clamping cloth is kept in the specific shape of the sealing template through a pressure head tool, and multiple times of forming are achieved; and S3, pre-burying the formed diaphragm framework material and the rubber sheet in a cavity, pre-pressing and forming through the pressure of a vulcanizing machine, then replacing a mold insert to enable the sealing template to be free of a clip, and then vulcanizing and forming. By designing the sealing membrane for reinforcing the fiber cloth, the sealing membrane can well bear medium pressure, wear resistance and mechanical dynamics performance.

Description

technical field [0001] The invention relates to the technical field of forming a rubber sealing diaphragm, in particular to a method and equipment for forming a fiber-reinforced rubber sealing diaphragm. Background technique [0002] Fiber-reinforced rubber composites are widely favored by researchers in the industry due to their unique mechanical and dynamic properties. Fiber materials have high specific strength, high toughness and good fatigue resistance, but have disadvantages such as low modulus and low shrinkage. The fiber polymer-based composite material for rubber reinforcement not only has excellent wettability and ductility of fiber materials, but also has more excellent strength properties, wear resistance and heat resistance properties, and is widely used in tires, conveyor belts, hoses and Seals and other fields. [0003] As a reinforcing material, fiber cloth has stronger compactness and higher structural order than fibers. Therefore, compared with fiber rei...
