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), paracril is cut into bulk with bale splitter, is placed in mill and carries out the thin-pass discharging after 5 times of plasticating, and place 8 ~ 12h;
(2), the sizing material after thin-pass is plasticated is placed in to 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 to mix, carry out mixing 10min;
(3), the rubber unvulcanizate completing after mixing is sent into mill slice, slice thickness 10 ~ 13mm, size 45cm * 65cm, more than then placing 10h;
(4), step (3) is sent into mill again from mill film out, and add sulphur and dicumyl peroxide to carry out slice after refining;
(5), the film after step (4) refining is carried out to the first one-step forming of Air Rubber Capsule;
(6), by step (5) just the Air Rubber Capsule of one-step forming be placed in the die cavity of Air Rubber Capsule mould and carry out moulding, and it is 150 ℃ by the temperature of vulcanizing press control moulding, pressure is 10Mpa, and the time is 120 min, and the cooling rear 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-anilino phenyl) maleimide.
Wherein, in described paracril, the content of vinyl cyanide is 42%, adopts the paracril of JSR220S model.
Beneficial effect: it is main body sizing material that Air Rubber Capsule of the present invention adopts paracril, 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, can activate sulphur 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 the high low temperature sulfidation of sizing material, improve the anti tear of sizing material, anti-mechanical property and the chemical properties such as fatigue of circumnutating 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, thereby increase the plasticity of sizing material.Solid coumarone resin contributes to carbon black dispersion and can improve sizing material to extrude 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, the corrosion that effectively protective hot, oxygen and copper manganese poisonous metal cause Air Rubber Capsule, 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, after the two combination, can improve physical strength and the elasticity of sizing material, and can improve the processing characteristics of sizing material, and give the properties such as goods abrasion performance, tear-resistant, heat-resisting, cold-resistant, oil resistant, extend the work-ing life of Air Rubber Capsule.Adopting sulphur and dicumyl peroxide is vulcanizing agent, so that sizing material has excellent snappiness, high strength and ageing-resistant cold tolerance.
