Abstract
The invention belongs to the field of rubber compositions, and in particular relates to a silicon rubber composition which is prepared from the following components in parts by weight: 60-80 parts of organic silicon raw rubber, 20-25 parts of linear polysiloxane, 8-12 parts of 2-methyl-4-ethyl heptane, 4-6 parts of diepoxypropane ethylether, 1-3 parts of carborundum and 1-3 parts of ceramic powder. Due to adoption of the organic silicon raw rubber, the ceramic powder and the like, the tension resistance and the anti-tear property of rubber are improved, the demand on silicon rubber with high mechanical property in a specific environment can be met, and the silicon rubber composition is simple in component and the raw materials are cheap and easily available.
Description
Technical field
The invention belongs to field of rubber composition, particularly relate to a kind of rubber composition.
Background technology
In numerous synthetic rubber, silicon rubber is outstanding person wherein.It has tasteless nontoxic, is not afraid of high temperature and the feature resisting severe cold, and " keeping cool ", " remaining calm " when 300 degrees Celsius and subzero 90 degrees Celsius, still do not lose original intensity and elasticity.Silicon rubber also has good electrical insulating property, oxytolerant resistance to deterioration, fast light resistance to deterioration and mildew resistance, chemical stability etc.But the mechanical propertys such as the tensile strength of existing rubber composition and tearing toughness are poor, can not meet the demand of specific environment.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, a kind of rubber composition possessing good mechanical properties is provided.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of rubber composition, its component is counted by weight: organosilicon rubber 60 ~ 80 parts, linear polysiloxane 20 ~ 25 parts, 2-methyl-4-ethyl heptane 8 ~ 12 parts, diepoxy propane ethyl ether 4 ~ 6 parts, 1 ~ 3 part, silicon carbide and 1 ~ 3 part, porcelain powder.
Further, a kind of rubber composition, its component is counted by weight: organosilicon rubber 70 ~ 80 parts, linear polysiloxane 23 ~ 25 parts, 2-methyl-4-ethyl heptane 10 ~ 12 parts, diepoxy propane ethyl ether 4 ~ 6 parts, 1 ~ 3 part, silicon carbide and 1 ~ 3 part, porcelain powder.
Further, a kind of rubber composition, its component is counted by weight: organosilicon rubber 75 parts, linear polysiloxane 24 parts, 2-methyl-4-ethyl heptane 10 parts, diepoxy propane ethyl ether 5 parts, 2 parts, silicon carbide and 2 parts, porcelain powder.
The invention has the beneficial effects as follows: the present invention adopts organosilicon rubber, porcelain powder etc. to strengthen tensile strength and the tearing toughness of rubber, meets the demand of specific environment to high-mechanical property silicon rubber; Moiety of the present invention is simple, and cheaper starting materials is easy to get.
