Problems solved by technology

However, at present, the rubber parts for brake master cylinders of domestic passenger cars all rely on imports, resulting in high automobile manufacturing costs, which seriously restricts the development of the domestic automobile industry. The mold is easy to crack and degumming will occur in the 150□ brake fluid, and the performance is very unstable

Embodiment 1

[0029] (1) Inner skeleton preprocessing:

[0030] Skeleton material: free-cutting steel;

[0031] Surface treatment: shot blasting, phosphating;

[0032] Adhesive ratio: Adhesive CH411 and diluent S220 are mixed according to 2:1;

[0033] Spraying method: Put the frame tightly and orderly on the special protective rod (the protective rod is self-made, it is made of steel wire, the length is 1 meter, and the diameter is the same as the inner diameter of the frame), and then use a spray gun to evenly spray the diluted The adhesive is sprayed on the outer surface of the skeleton;

[0034] Drying: The skeleton after spraying the adhesive is sent to the drying tunnel, and dried at 140°C to 150°C for 8 to 10 minutes;

[0035] Packaging: Put the dried skeleton in a clean plastic bag, label it, put it in a desiccant, and store it in the warehouse for later use;

[0036] (2) Prepare raw materials according to the following parts by weight: 80-120 ethylene-propylene rubber, 6-10 imp...

Abstract

The invention discloses a center valve sealing ring material for a brake master cylinder of a car and a process for manufacturing the sealing ring. The material is manufactured by 80-120 parts of ethylene propylene rubbers, 6-10 parts of activating agents, 1-3 parts of lubricating agents, 2-4 parts of acid-base equilibrium agents and 1-3 parts of vulcanizing agents by weight through the processesof mixing, molding, vulcanizing and trimming. The manufactured sealing ring product has high strength, low compression, tear resistance, excellent resistance to various oil corrosion and high / low temperature and high production efficiency and product percent of pass and can absolutely replace the imported products of the same kind.

Description

technical field [0001] The invention relates to a center valve seal ring for a car brake master cylinder, in particular to a material for a center valve seal ring for a car brake master cylinder and a process for manufacturing the seal ring. Background technique [0002] The car brake master cylinder uses the principle of incompressibility of liquid to convert the mechanical pressure on the pedal of the driver into hydraulic pressure, which is transmitted to the brakes of the four wheels to slow down or stop the car, so it plays an extremely important role in the braking system. important role. The central valve sealing ring for the car brake master cylinder is one of the key rubber parts in the car brake master cylinder. It is located on the piston, and through its control in the braking state, it can cut off the passage of the brake chamber and the liquid supply chamber. ; In the state of brake release, through its control, the brake fluid can be compensated to the brake ...
