Problems solved by technology

[0003] At present, the piston seals of domestic automatic transmissions mainly rely on imports, and the products come from companies such as KACO in Germany, Federal-Mogul in the United States or NOK in Japan, but the prices are very high
However, due to the high requirements for the material of the automatic transmission piston sealing ring, such as good mechanical strength, stiffness, heat aging resistance, compression set resistance, cold resistance, oil resistance and wear resistance, etc., domestic production basically blank

Abstract

The invention relates to the field of rubber technology, and particularly relates to a rubber material for an oil seal of an automatic transmission. The rubber material comprises the following raw materials in parts by weight: 100 parts of rubber raw material AEM, 1-2 parts of stearic acid, 1-2 parts of anti-aging agent 445, 5-10 parts of plasticizer TP-759, 3-4 parts of accelerant, 1-2 parts of vulcanizing agent Diak1-1, 5-15 parts of gaseous white carbon black, 70-85 parts of fast extruding furnace black, 1-2 parts of VAM (Vinyl Acetate Monomer) and 0.3-0.6 part of 18D. The rubber material has the beneficial effects that the rubber material has excellent mechanical strength, high rigidity, good heat resistance and aging-resistance properties, and excellent compression and permanent deformation resistance properties; the oil resistance property and wear resistance property can be enhanced; the rubber material has a large high and low temperature resistance range, so that the oil seal product of the automatic transmission can be used for a long time under the environment of -40 DEG C to 160 DEG C and the service life of the oil seal of the automatic transmission can be greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber material for an automatic transmission oil seal. Background technique [0002] With the growth of automobile demand and the increase of the loading ratio of automatic transmission, the demand for automatic transmission is growing rapidly. Therefore, as the core sealing technology of automatic transmission, the piston sealing ring of automatic transmission must also maintain a high-speed growth in demand. [0003] At present, the piston seals of domestic automatic transmissions mainly rely on imports. The products come from companies such as KACO in Germany, Federal-Mogul in the United States or NOK in Japan, but the prices are very high. However, due to the high requirements for the material of the automatic transmission piston sealing ring, such as good mechanical strength, stiffness, heat aging resistance, compression set resistance, cold resistance, oil resistance and...
