Abstract
The invention relates to a modified oil-resistant fluorosilicone rubber gasket comprising the following components: 170 parts of methyl vinyl silicone rubber, 50 parts of methyl vinyl trifluoropropyl silicone rubber, 7 parts of fumed silica, 3 parts of diphenyl benzoate, 5 parts of methyl-2,2-dithienyl glycolate and 2 parts of naphthenic oil. A rubber pinching pipe further comprises 2 parts of anti-aging agent and 1 part of triallyl isocyanurate. By implementation of the modified oil-resistant fluorosilicone rubber gasket, the oil resistance of silicone rubber is effectively improved, and the formula of the modified oil-resistant fluorosilicone rubber gasket can partially replace fluorosilicone rubber and can be used for oil-resistant occasions.
Description
Technical field
The present invention relates to a kind of rubber item, especially a kind of modification oil resistant trifluoropropyl siloxane pad.
Background technology
Silicon rubber has excellent resistant of high or low temperature, ozone resistance, chemerosiveness resistent and electric property, and therefore, silicon rubber, in all respects of national economy, is especially widely used in automobile industry.But because silicon rubber itself is not good to the anti-patience of non-polar oil, this has just limited the range of application of silicon rubber greatly, and along with the raising of people's environmental consciousness, motor vehicle emission, fuel oil infiltration etc. has all been proposed to more and more higher requirement, traditional silicon rubber has been difficult to meet these requirements.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of modification oil resistant trifluoropropyl siloxane pad.
For solving the problems of the technologies described above, modification oil resistant trifluoropropyl siloxane pad of the present invention, comprises following component, 170 parts of methyl vinyl silicone rubbers, 50 parts, methyl ethylene trifluoro propyl silicon rubber, 7 parts of thermal silicas, 3 parts of dibenzoates, 5 parts of 2,2-dithienyl methyl glycolate, 2 parts of naphthenic oils.
Described rubber clamp also comprises 2 parts, anti-aging agent.
Described rubber clamp also comprises 1 part of triallyl isocyanurate.
Enforcement of the present invention has effectively improved the oil resistance of silicon rubber, this formula can partly replace trifluoropropyl siloxane for oil resistant occasion, simultaneously, owing to containing silicon rubber and trifluoropropyl siloxane composition in sizing material simultaneously, for oil resistant, have relatively high expectations, must use the occasion of trifluoropropyl siloxane, this formula can be used as the middle layer of trifluoropropyl siloxane and silicon rubber, both are bonded together, form trifluoropropyl siloxane and silicon rubber composite structure.
