Abstract
The invention relates to the technical field of rubber materials, and specifically relates to a silicone rubber composition. The silicone rubber composition is composed of the following components in parts by weight: 60 to 70 parts of raw rubber of methyl phenyl vinyl silicone rubber, 2 to 4 parts of silicon dioxide, 4 to 6 parts of supplement, 1.5 to 3 parts of hydroxy silicone oil, 1.5 to 2 parts of hydrogen-containing silicone oil, 2 to 6 parts of foaming agent, and 2 to 5 parts of catalyst. The invention aims to provide a silicone rubber composition having the advantages of low production cost, reasonable formula, and stable properties.
Description
Technical field
The present invention relates to the technical field of elastomeric material, specifically a kind of rubber composition.
Background technology
Silicon rubber, as a kind of specialty elastomer, belongs to synthetic rubber.Silicon rubber is widely used in electrical equipment, field of motor vehicles, building field, medical field, field of food industry and other various fields as weathering resistance, electrical property, low compression deformation, thermotolerance and winter hardiness because of its excellent properties.Silicon rubber has the following advantages: have the excellent properties such as high-low temperature resistant, electric insulation, resistance to ozone, radiation hardness, difficult combustion, hydrophobic, corrosion-resistant, nonpoisonous and tasteless and physiological inertia.But due to the expensive raw material price of existing silicon rubber, make its production cost very high, limit further application.
Summary of the invention
The object of this invention is to provide a kind of low production cost, formula is reasonable, the rubber composition of stable performance.
The technical solution used in the present invention is, a kind of rubber composition, is made up of by weight following component: methyl phenyl vinyl silicone rubber rubber 60-70 part, silicon-dioxide 2-4 part, supplement 4-6 part, hydroxy silicon oil 1.5-3 part, containing hydrogen silicone oil 1.5-2 part, whipping agent 2-6 part, catalyzer 2-5 part.
Say further, described supplement are white carbon blacks.
Say further, described hydroxy silicon oil is low polymerization degree α, alpha, omega-dihydroxy polymethyl siloxane.
Say further, described white carbon black is precipitated silica.
Advantage of the present invention is low production cost, and rationally, starting material are easy to get formula, oil-resistant high-temperature, stable performance.
