The invention provides a rubber sealing gasket for a gearbox oil pan, which mainly comprises a framework and rubber, wherein the framework is composed of a metal framework and a lining, the rubber is prepared from acrylate rubber (ACM) and ethylene Acrylate (AEM), the metal framework can be ST12, and the lining can be made of No. 20 steel.
In addition, the invention also provides rubber for the rubber sealing gasket for the gearbox oil pan, which comprises the following components in parts by weight: 30-80 parts of ACM, 20-70 parts of AEM, 40-70 parts of carbon black, 2-15 parts of white carbon black, 0.5-2 parts of stearic acid, 1-3 parts of anti-aging agent, 2-4 parts of processing aid, 0.5-2 parts of anti-scorching agent, 4-10 parts of plasticizer, 0.5-4 parts of paraffin oil, 1-2 parts of vulcanizing agent and 1.5-3 parts of accelerator.
The invention also provides a corresponding manufacturing method, which mainly combines the metal framework and the bush together in advance through interference fit, phosphorizes, and coats the special adhesive for acrylate glue.
And vulcanizing the rubber in the step 2 and the skeleton after treatment in the step 3 in a corresponding mold on a vulcanizing machine for 6-10 minutes to prepare the rubber sealing gasket for the oil pan of the gearbox.
The invention has the beneficial effects that by means of the technical scheme, the invention has the following advantages:
1. the rubber is combined by ACM and AEM, so that the oiliness resistance of the automatic transmission of the ACM rubber is improved, and the tensile strength and the tear strength are improved.
2. The addition of the white carbon black improves the tearing strength of the rubber and reduces the high-temperature stress damage of the gasket (shown in figure 2).
3. The addition of the paraffin oil improves the extraction property of the auxiliary agent which is easy to extract in the rubber material, and reduces the phenomenon of blooming.
