For achieving the above object, technical scheme of the present invention is: oil resistant Air Rubber Capsule, count by weight, it consists of: 15 ~ 25 parts of paracrils, 0.5 ~ 1.5 part of zinc oxide, 0.1 ~ 0.5 part of stearic acid, 0.1 ~ 0.5 part of altax, 0.1 ~ 0.3 part of accelerant CZ, 1 ~ 3 part of dioctyl phthalate (DOP), 0.5 ~ 1.5 part of coumarone indene resin, 0.1 ~ 0.2 part of antioxidant D MBPPD, 0.1 ~ 0.2 part of antioxidant MB, 0.1 ~ 0.3 part of antioxidant H B-5,3 ~ 6 parts of spray carbon blacks, 1 ~ 3 part of white carbon black, 0.2 ~ 0.4 part of sulphur and 0.1 ~ 0.2 part of dicumyl peroxide.
The preparation method of described oil resistant Air Rubber Capsule, comprises the steps:
(1), by paracril bale splitter be cut into bulk, be placed in mill and carry out thin-pass and to plasticate discharging after 5 times, and place 8 ~ 12h;
(2), the sizing material after plasticating through thin-pass is placed in Banbury mixer, and add zinc oxide, stearic acid, altax, accelerant CZ, dioctyl phthalate (DOP), coumarone indene resin, antioxidant D MBPPD, antioxidant MB, antioxidant H B-5, spray carbon black and white carbon black and mix, carry out mixing 10min;
(3), by complete mixing after rubber unvulcanizate send into mill slice, slice thickness 10 ~ 13mm, size 45cm × 65cm, then place more than 10h;
(4), by step (3) again send into mill from mill film out, and add sulphur and dicumyl peroxide and carry out slice after refining;
(5), the film after step (4) refining is carried out the first one-step forming of Air Rubber Capsule;
(6) carry out shaping in the die cavity, the Air Rubber Capsule of the first one-step forming of step (5) being placed in Air Rubber Capsule mould, and to control shaping temperature with vulcanizing press be 150 DEG C, pressure is 10Mpa, and the time is 120min, and after cooling, namely the demoulding obtains oil resistant Air Rubber Capsule finished product.
Wherein, described altax, its chemical name is: 2,2'-dithio-bis-benzothiazole; Accelerant CZ, its chemical name is: N-cyclohexyl-2-benzothiazole sulfonamide; Antioxidant D MBPPD, its chemical name is: N-(1,3-dimethylbutyl)-N'-diphenyl-para-phenylene diamine or N-(1-methyl isopentyl)-N'-diphenyl-para-phenylene diamine; Antioxidant MB, its chemical name is: 2-mercaptobenzimidazole; Antioxidant H B-5, its chemical name is: N-(4-aniiinophenyl) maleimide.
Wherein, in described paracril, the content of vinyl cyanide is 42%, adopts the paracril of JSR220S model.
Beneficial effect: Air Rubber Capsule of the present invention adopts paracril to be main body sizing material, and dioctyl phthalate (DOP) and coumarone indene resin are softening agent, and spray carbon black and white carbon black are reinforcing filler, and sulphur and dicumyl peroxide are vulcanizing agent.Wherein, zinc oxide forms zinc soap under stearic acid coordinates, and makes it to be easy to be dissolved in sizing material, and form a kind of binding substances with altax and accelerant CZ, make promotor more active, in addition, sulphur can be activated and form very strong vulcanizing agent, improve vulcanized rubber glue and connect density and heat aging property.Altax and accelerant CZ use, can continue to improve cross-linking density in sizing material high/low temperature sulfidation, improves the anti tear of sizing material, anti-circumnutate mechanical property and the chemical property such as tired simultaneously.Adopt dioctyl phthalate (DOP) to increase the distance of rubber molecule interchain, reduce intermolecular reactive force, and produce lubrication, make easily to slide between molecular chain, thus increase the plasticity of sizing material.Solid coumarone resin contributes to carbon black dispersion and can improve sizing material extruding the processing performances such as calendering and tackiness, and energy dissolution of sulphur is uniformly dispersed and prevents incipient scorch, can also improve physical and mechanical properties and the ageing resistance of cross-linked rubber.Antioxidant D MBPPD and antioxidant MB use, can the effectively corrosion that causes Air Rubber Capsule of protective hot, oxygen and copper manganese poisonous metal, and antioxidant H B-5 has the effect of anti-old heat-resisting media-resistant corrosion.Spray carbon black and white carbon black are also used, the two can improve physical strength and the elasticity of sizing material after combining, and the processing characteristics of sizing material can be improved, give goods abrasion performance, tear-resistant, heat-resisting, cold-resistant, resistance to wet goods property, extend the work-ing life of Air Rubber Capsule.Adopt sulphur and dicumyl peroxide to be vulcanizing agent, to make sizing material, there is excellent snappiness, high strength and Ageing-resistant cold-resistant performance.
