Description
Technical field
The invention belongs to rubber processing techniques field, and in particular to a kind of wearability seal rubber.
Background technology
The main function of seal is to prevent leakage, and it can play the gap for sealing faying face, and cut-out leakage channel reaches
Prevent the purpose of leakage.But automobile or machinery seal, it is desirable to sealing property of sealing component is good, safe and reliable, long lifespan, and
And have higher heat-resisting and anti-wear performance simultaneously, damage caused by reduce it in mechanical movement, confirm that it keeps for a long time
Function affect.And mainly based on natural rubber, used preparation raw material is processed into close seal rapidoprint at present
Sealing, it is usually poor in anti-wear performance, it is difficult to reach seal requirement.
The content of the invention
The problem of present invention is existing：For automobile or the seal of mechanical field, itself and Mechanical Contact have larger rub
Wipe, for a long time using sealing part abrasion can be caused, cause the reduction of its sealing effectiveness, its feature declines；And at present with natural rubber
Glue is the seal mainly to process raw material, and its anti-wear performance is poor, it is impossible to keeps the security performance of seal.To solve above-mentioned ask
Topic, the invention provides a kind of wearability seal rubber.
The present invention is achieved by the following technical solutions：
A kind of wear-resisting type seal rubber, it is respectively configured to sub-prime gauge part and is：
Natural rubber 400-500 parts, nitrile rubber 40-60 parts, poly- allene siloxanes 20-30 parts, zinc chloride 8-10 parts, tristearin
Sour 5-7 parts, carbon black 7-9 parts, paraffin 6-9 parts, titanium oxide 3-5 parts, aminodithioformic acid 7-10 parts, vulcanization hexichol thiazole 4-6
Part.
A kind of wear-resisting type seal rubber, comprises the following steps：
（1）Mixing：Natural rubber, nitrile rubber etc. are heated to 220-230 DEG C, constant temperature keeps 1-2h；（2）Plasticate, be kneaded：Will
Step（1）Gained colloid is through plasticating, mixed refining process；
（3）Shaping：By step（2）Seal is made in obtained rubber after extrusion forming；
（4）Vulcanization：By seal after vulcanizing treatment finished product seal.
Step（4）Described vulcanizing treatment, its temperature are 85-89 DEG C, and sulfur dioxide volumetric concentration is 53%-56%.
Further, it is made up of the composition of following quality meter part：
470 parts of natural rubber, 56 parts of nitrile rubber, 27 parts of poly- allene siloxanes, 9.6 parts of zinc chloride, 6.7 parts of stearic acid, charcoal
Black 8.3 parts, 7.8 parts of paraffin, 4.5 parts of titanium oxide, 9.4 parts of aminodithioformic acid, 5.8 parts of vulcanization hexichol thiazole.
The present invention has advantages below compared with prior art：Pass through the rubber seal that rubber formulation composition of the present invention is made
Glue, there is higher anti-wear performance, and it is high in resistance to elevated temperatures, and shrinkage factor is small.
