Abstract
The invention discloses oil resistant rubber, belonging to the technical field of rubber for automobile oil cylinder sealing. The oil resistant rubber is prepared from the following components in parts by weight: 35-46 parts of styrene-isoprene-butadiene rubber, 20-30 parts of isoprene-butadiene rubber, 20-26 parts of polyhexamethylene biguanide hydrochloride, 8-12 parts of zinc oxide, 5-8 parts of dithiodimorpholine, 2-4 parts of stearic acid, 1-5 parts of isobutyltriethoxysilicon, 5-8 parts of ethyl carbamate and 1-5 parts of sodium pyrosulfite. The oil resistant rubber is prepared by mainly compounding two types of conjugated diene rubber and then adopting the following auxiliary components: 26 parts of polyhexamethylene biguanide hydrochloride, zinc oxide, dithiodimorpholine, stearic acid, isobutyltriethoxysilicon, ethyl carbamate and sodium pyrosulfite, so that the oil resistance of the oil resistant rubber can be effectively improved.
Description
Technical field
The present invention relates to automobile oil cylinder sealing field of rubber technology, particularly relate to a kind of oil resisting rubber.
Background technology
Along with the development of auto manufacturing technology, the performance requriements of people to each parts of automobile is also more and more higher, particularly about the oil resistance requirement of automobile oil cylinder sealing rubber.At present, although existing oil resisting rubber product category is various, but the problem of ubiquity oil-proofness poor performance.
Summary of the invention
The invention provides a kind of oil resisting rubber, this oil resisting rubber oil-proofness is good, can solve the problem that existing oil resisting rubber product also exists oil-proofness poor performance.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
It is made up of the component of following weight part:
Styrene isoprene butadiene rubber (SIBR) 35 parts ~ 46 parts, isoprene-butadiene rubber 20 parts ~ 30 parts, hexamethylene 20 parts ~ 26 parts, 8 parts ~ 12 parts, zinc oxide, dimorpholinyl disulfide 5 parts ~ 8 parts, stearic acid 2 parts ~ 4 parts, isobutyl-triethoxysilicane 1 part ~ 5 parts, urethanum 5 parts ~ 8 parts and Sodium Pyrosulfite 1 part ~ 5 parts.
In technique scheme, technical scheme is more specifically: styrene isoprene butadiene rubber (SIBR) 35 parts, isoprene-butadiene rubber 20 parts, hexamethylene 26 parts, 12 parts, zinc oxide, dimorpholinyl disulfide 7 parts, stearic acid 3 parts, isobutyl-triethoxysilicane 1 part, urethanum 8 parts and Sodium Pyrosulfite 3 parts.
Further, styrene isoprene butadiene rubber (SIBR) 46 parts, isoprene-butadiene rubber 30 parts, hexamethylene 26 parts, 8 parts, zinc oxide, dimorpholinyl disulfide 5 parts, stearic acid 4 parts, isobutyl-triethoxysilicane 5 parts, urethanum 6 parts and Sodium Pyrosulfite 5 parts.
Further, styrene isoprene butadiene rubber (SIBR) 40 parts, isoprene-butadiene rubber 25 parts, hexamethylene 22 parts, 10 parts, zinc oxide, dimorpholinyl disulfide 8 parts, stearic acid 2 parts, isobutyl-triethoxysilicane 3 parts, urethanum 5 parts and Sodium Pyrosulfite 1 part.
Owing to adopting technique scheme, the beneficial effect that the present invention obtains is:
The present invention mainly selects two kinds of conjugated diene rubbers composite, then is equipped with hexamethylene 26 parts, zinc oxide, dimorpholinyl disulfide, stearic acid, isobutyl-triethoxysilicane, urethanum and Sodium Pyrosulfite make oil resisting rubber together, can effectively improve its oil resistance.
