Description
Technical field
The present invention relates to a kind of rubber technology field, relate in particular to a kind of automatic gear-box oil sealing elastomeric material.
Background technology
Along with automobile demand amount growth and the raising of automatic transmission entrucking ratio, the demand rapid growth of automatic transmission.Therefore, automatic gear-box piston ring is as the core packing technique of automatic transmission, and its demand also must keep rapid growth.
At present, the piston packing of domestic automatic transmission mainly relies on import, and product, from the NOKDeng company of German KACO, U.S. Federal-Mogul or Japan, but brings a high price.And because automatic gear-box piston ring is very high to the requirement of its material, as needs have good physical strength, rigidity, heat aging property, incompressible tension set performance, winter hardiness, oil resistance and wear resisting property etc., it is blank that domestic production substantially also belongs to.Therefore the exploitation of automatic gear-box piston packing loop material is extremely urgent.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of automatic gear-box oil sealing elastomeric material is provided.This elastomeric material is functional, long service life.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of automatic gear-box oil sealing elastomeric material, is comprised of the raw material of following weight:
On the basis of technique scheme, the raw material being preferably by following weight forms: the rubber raw materials AEM of 100 parts, the stearic acid of 1.5 parts, the softening agent TP-759 of 445,7 parts, the anti-aging agent of 1.5 parts, the vulkacit D OTG of 3.5 parts, the vulcanizing agent Diak1# of 1.5 parts, the gas-phase silica of 10 parts, the fast extrusion carbon black of 75 parts, the VAM of 1 part, the 18D of 0.4 part.
Elastomeric material of the present invention makes by ordinary method.
The AEM rubber raw materials that the present invention uses, when guaranteeing low temperature, selects oil resistance to improve and the higher trade mark of mooney viscosity, and sizing material has higher physical strength and good processing characteristics like this.
The present invention adopts rate accelerating material(RAM) TP-759, fabulous improvement the resistance to low temperature of material.
The present invention is added with gas-phase silica, can obviously improve automatic transmission fluid and be enclosed in the tear resistance in to-and-fro movement.
The present invention adopts amine curing agents sulfuration, incompressible tension set excellent property.
Elastomeric material of the present invention has excellent physical strength, higher rigidity, good heat aging property and good incompressible tension set performance, improve oil resistance and wear resisting property, filled up the blank of elastomeric material for domestic wheel box oil sealing, good high low temperature resistance range, can make automatic transmission fluid envelope product meet life-time service under-40 ℃～160 ℃ environment, the work-ing life of greatly having improved automatic gear-box oil sealing.
