Change zinc, 2 ~ 4 parts of vulcanizing agents, 1 ~ 3 part of antioxidant.
It is preferred that, by the material composition of following parts by weight：
53 parts of nitrile rubbers, 32 parts of butadiene-styrene rubber, 18 parts of silica flours, 23 parts of attapulgite modified, 9 parts of zinc oxide, 3 parts of vulcanizing agents, 2
Part antioxidant.
Further, the granular size of the silica flour is 400 ~ 450 mesh.
Further, the attapulgite modified preparation method comprises the following steps：
（1）It is 1 ~ 2h of calcination processing under conditions of 1000 ~ 1100 DEG C that attapulgite first is put into temperature, after the completion of take out standby
With；
（2）By step（1）Attapulgite after processing is put into 1 ~ 1.5h of immersion treatment in modification liquid, after the completion of filter out it is dry
It is dry to weighing；Each composition and its correspondence parts by weight are in described modification liquid：25 ~ 30 portions of acetic anhydrides, 5 ~ 8 portions of lemons
Acid, 2 ~ 4 parts of rare earths, 8 ~ 11 parts of ethylene glycol, 180 ~ 200 parts of water.
Further, step（2）Described in immersion treatment when heating keep modification liquid temperature be 70 ~ 75 DEG C.
Further, step（2）Described in drying process temperature be 80 ~ 85 DEG C.
The present invention has advantages below compared with prior art：
The present invention has carried out rational adjustment to each constituent of rubber seal and arranged in pairs or groups, and effectively improving to coordinate each other makes
Effect, wherein attapulgite are now more to be filled in rubber matrix with the effect such as suspending agent, binding agent, can effectively improve rubber
Glue overall intensity, heatproof, corrosion resistant, stability etc., but there is when high temperature, low temperature, external force are excessive and in rubber into
Point the phenomenon of glass of coming off is produced, so as to have impact on overall use quality and life-span, this present invention is carried out to attapulgite
Special modification, specifically carries out grafting acetylation process with the acetic acid anhydride component in modification liquid to its surface,
The activity of attapulgite is improved well, its bond strength between rubber matrix and remaining composition, Jin Ergai is enhanced
It has been apt to the use quality of entirety.Under the common mating reaction of each composition, rubber seal produced by the present invention has good
High temperature resistant, low temperature resistant, wear-resisting, corrosion resistant, impact resistance characteristic, integrated quality are good, and service life can extend more than 35%, great popularization
Value and the market competitiveness.
