Abstract
The invention discloses an ozone-proof rubber. The ozone-proof rubber is prepared from the following raw materials in parts by weight: 130-140 parts of fluororubber, 6-8 parts of toluene diisocyanate, 15-20 parts of magnesium oxide, 3-5 parts of calcium hydroxide, 0.8-1.5 parts of fluorinated wax, 5-7 parts of carbon black, 1-3 parts of siloxane, 10-15 parts of toluene diisocyanate, 5-10 parts of dicumyl peroxide, 2-6 parts of polyvinyl alcohol, 0.2-1.0 part of anti-aging agent, 7-12 parts of trialuminum tetraoxide and 3-5 parts of methoxy hydrogen peroxide. The ozone-proof rubber can be used for overcoming the defects of the prior art, and is capable of retarding the reaction of ozone in the air with the rubber, and therefore, the service life of the rubber can be increased, the application range of the rubber products is greatly expanded and then the rubber products can be applied to relatively severe environments, and consequently, the competiveness of an enterprise can be improved.
Description
Technical field
The present invention relates to rubber technology field, belong to a kind of anti-ozone rubber.
Background technology
Rubber item is easily aging is because contain ozone in atmosphere, because ozone is more active than central enterprise, so it is more much harder than oxygen to the invasion and attack of the especially undersaturated rubber of rubber.
It is reported, undersaturated rubber is easy to be oxidized with ozone, and external appearance characteristic and thermo-oxidative ageing after ozonize are different, ozonize is to carry out on the surface of rubber item, it is process from outward appearance to inner essence, and rubber and ozone can generate the argenteous dura mater of one deck (approximately 10nm is thick) when reacting, under static condition, this tunic can stop ozone to contact with rubber deep layer.Make film be full of cracks as long as no external force, rubber will no longer continue ozonize.If the rubber of ozonize is stretched or makes it produce dynamic deformation, will there is be full of cracks in the ozonize film of generation, expose new rubber surface and can react with ozone again, and this makes crackle continue to increase.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of anti-ozone rubber is provided, made by the raw material of following weight part: 135 parts of viton, 7 parts of toluene di-iso-cyanide esters, 18 parts, magnesium oxide, 4 parts, calcium hydroxide, 1 part, fluorine wax, 6 parts of carbon blacks, 2 parts of siloxanes, 12 parts of toluene di-iso-cyanide esters, 8 parts of dicumyl peroxides, 4 parts of polyvinyl alcohol, the consumption of anti-aging agent is 0.5 part, 10 parts of miniums, 4 parts of compositions of methoxyl group hydroperoxide.
The present invention adopts following technical scheme to achieve these goals:
A kind of anti-ozone rubber, is made up of the raw material of following weight part: viton 130-140 part, toluene di-iso-cyanide ester 6-8 part, magnesium oxide 15-20 part, calcium hydroxide 3-5 part, fluorine wax 0.8-1.5 part, carbon black 5-7 part, siloxanes 1-3 part, toluene di-iso-cyanide ester 10-15 part, dicumyl peroxide 5-10 part, polyvinyl alcohol 2-6 part, the consumption of anti-aging agent is 0.2～1.0 part, minium 7-12 part, methoxyl group hydroperoxide 3-5 part.
Preferred: 135 parts of viton, 7 parts of toluene di-iso-cyanide esters, 18 parts, magnesium oxide, 4 parts, calcium hydroxide, 1 part, fluorine wax, 6 parts of carbon blacks, 2 parts of siloxanes, 12 parts of toluene di-iso-cyanide esters, 8 parts of dicumyl peroxides, 4 parts of polyvinyl alcohol, the consumption of anti-aging agent is 0.5 part, 10 parts of miniums, 4 parts of methoxyl group hydroperoxides.
In preferred anti-ozone rubber, also contain resin 20-30 part.
Compared with the prior art, beneficial effect of the present invention is as follows:
Anti-ozone rubber of the present invention, ozone and rubber reaction in can slow down air, from increasing the work-ing life of rubber, have improved the use range of rubber item greatly, is applied in some relatively rugged environments, improves the competitive power of enterprise.
Embodiment
Below in conjunction with embodiment, the invention will be further described, but the present invention is not limited only to these examples, under the prerequisite for departing from aim of the present invention, within any improvement of doing all drops on protection scope of the present invention.
Embodiment:
A kind of anti-ozone rubber, is made up of the raw material of following weight part: 135 parts of viton, 7 parts of toluene di-iso-cyanide esters, 18 parts, magnesium oxide, 4 parts, calcium hydroxide, 1 part, fluorine wax, 6 parts of carbon blacks, 2 parts of siloxanes, 12 parts of toluene di-iso-cyanide esters, 8 parts of dicumyl peroxides, 4 parts of polyvinyl alcohol, the consumption of anti-aging agent is 0.5 part, 10 parts of miniums, 4 parts of methoxyl group hydroperoxides.
