Problems solved by technology

The brake master cylinder has the function of converting the mechanical energy input from the outside into hydraulic energy, and then makes the hydraulic energy output to the brake wheel cylinder through the pipeline. It is the core component of the brake device to achieve the purpose of braking. Therefore, the brake master The sealing ring of the oil inlet of the cylinder is subjected to huge oil pressure. Once defects such as expansion, contraction or rupture appear, it will directly lead to brake failure and threaten the lives of drivers and passengers.
However, at present, the rubber parts for brake master cylinders of domestic passenger cars all rely on imports, resulting in high automobile manufacturing costs and seriously restricting the development of the domestic automobile industry. The problem that the mold is easy to crack, the performance is very unstable

Abstract

The invention discloses an oil inlet sealing ring material for a vehicle brake master cylinder and a process thereof for manufacturing a sealing ring. The material is prepared from the following components in part by weight: 80 to 120 parts of ethylene propylene rubber, 4 to 6 parts of active agent, 1 to 3 parts of lubricant, 2 to 4 parts of acid-base balance agent, 1 to 3 parts of age resistor, 2 to 4 parts of sulfurizing agent and 25 to 35 parts of inorganic filler; then the components are subjected to the processes, namely mixing and molding, primary sulfurizing, punching and edge removingand secondary sulfurizing to obtain the oil inlet sealing ring material product with high strength, low compression deformation, tear resistance, resistance to braking fluid corrosion, resistance to low and high temperatures and excellent performance for the vehicle brake master cylinder; and the production efficiency and the product percent of pass are high, and the product can completely substitute similar imported products.

Description

technical field [0001] The invention relates to an oil inlet sealing ring, in particular to an oil inlet sealing ring material for an automobile brake master cylinder and a process for manufacturing the sealing ring. Background technique [0002] The braking device is a device that slows down the moving car or stops it within the shortest distance as required, so that the car can maximize its high-speed driving performance under the premise of ensuring safety. It also has the function of maintaining a certain speed when the car goes downhill and The function of ensuring that the car can reliably stop on the slope without slipping is closely related to driving safety. The brake master cylinder has the function of converting the mechanical energy input from the outside into hydraulic energy, and then makes the hydraulic energy output to the brake wheel cylinder through the pipeline. It is the core component of the brake device to achieve the purpose of braking. Therefore, the ...
