Abstract
The invention discloses an aging resistant O-shaped ring composite rubber. The aging resistant O-shaped ring composite rubber is prepared from following raw materials, by weight, 0.1 to 2 parts of stearic acid, 10 to 20 parts of sisal fiber, 1 to 2 parts of aluminium hydroxide, 0.1 to 0.2 part of peanut oil, 10 to 20 parts of waste tread rubber, 3 to 5 parts of borax, 1 to 2 parts of magnesium oxide, 1 to 2 parts of magnesium carbonate, 2 to 3 parts of Trioctyl trimellitate, 1.5 to 3 parts of vulcanizing agent PDM, 1 to 2 parts of promoter TE, 50 to 73 parts of natural rubber, 2 to 4 parts of butadiene-styrene rubber, and 35 to 40 parts of a modified filling material. The aging resistant O-shaped ring composite rubber is excellent in aging resistance, is friendly to the environment, and is nontoxic. Waste tread rubber is taken as a raw material, so that waste is changed into valuables.
Description
Technical field
The present invention relates to field of rubber materials, is exactly a kind of ageing-resistant composite rubber of O type circle.
Background technology
O RunddichtringO O type circle (O-rings) is that a kind of cross section is circular rubber seal, because its cross section is O type, therefore be called O RunddichtringO, is also O type circle.Start to appear in the middle of the 19th century, with it, make at that time the sealing element of steamer cylinder.
O RunddichtringO is applicable to be contained in various mechanical means, in the temperature, pressure of regulation and different liquids and gases medium, under static or kinestate, seals.On lathe, boats and ships, automobile, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, building machinery, mining machinery, petroleum machinery, plastics machinery, agricultural machine and all kinds of instrument, widely applying various types of sealing elements.O RunddichtringO is mainly used in static seal and reciprocating movement sealing.While being used for rotatablely moving sealing, only limit to low speed rotary seal.O RunddichtringO is generally arranged in the groove that cylindrical or inner circle upper section are rectangle and seals.O RunddichtringO still plays excellent sealing, cushioning effect at environment such as oil resistant, soda acid, mill, chemical erosions.Therefore, O RunddichtringO is most popular a kind of sealing member in hydraulic and pneumatic transmission system.
Summary of the invention
The object of the present invention is to provide a kind of ageing-resistant composite rubber of O type circle.
Above-mentioned purpose realizes by following scheme:
A kind of ageing-resistant composite rubber of O type circle, it is characterized in that: it is to be made by the raw material of following weight parts: stearic acid 0.1-2, sisal fibers 10-20, aluminium hydroxide 1-2, peanut oil 0.1-0.2, discarded tread rubber 10-20, borax 3-5, magnesium oxide 1-2, magnesiumcarbonate 1-2, trioctyl trimellitate 2-3, vulcanizing agent PDM 1.5-3, acceterator TE 1-2, natural rubber 50-73, butadiene-styrene rubber 2-4, modified filler 35-40;
