Abstract
A method for preparing a rubber material by using a vulcanization system relates to the field of rubber production. The method comprises the following steps: placing ethylene propylene rubber in an internal mixer, plasticating at 120-140DEG C for 60-80s, adding an antioxidant mixture, mixing at 120-140DEG C for 30-40s, adding carbon black, calcium carbonate, paraffin oil and polyethylene wax, carrying out internal mixing for 60-120s to obtain first stage rubber, placing the first stage rubber in an open mixer, adding CZ, PZ, a vulcanizing agent benzoyl peroxide and a fire retardant ammonium polyphosphate ester, carrying out open mixing at 55-70DEG C until the section is uniform in order to obtain second stage rubber, molding the second stage rubber, and vulcanizing the molded second stage rubber in a vulcanization machine at 170-185DEG C for 8-10min to obtain a product. The sulfur donator vulcanization system is adopted to vulcanize the ethylene propylene rubber, so the method allows the use amount of sulfur to be small, and causes no blooming phenomenon.
Description
Technical field
The present invention relates to rubber and manufacture field.
Background technology
The preparation method of current rubber packing material adopts second third glue to be basic rubber raw material, with a certain amount of carbon black, and calcium carbonate, protective agent, promotor, dispersion agent, sulfur vulcanizing agent, the cooperations such as fire retardant, through banburying, open refining, the sulfuration process of sulphur-promotor vulcanization system is prepared from.
The vulcanization system adopted due to second third glue is sulphur-promotor vulcanization system, and this kind of vulcanization system is using sulphur as vulcanizing agent, and sulphur is the basic reason causing bloom phenomenon, in sulfidation, this kind of method requires to use a large amount of sulphur, is difficult to hold to sulfur consumption, when sulfur consumption is greater than saturated and supersaturation solubleness, sulphur is in meta and unsteady state, and this is that temperature reduction can cause occurring bloom phenomenon on elastomeric material surface.
Summary of the invention
The object of this invention is to provide a kind of method adopting vulcanization system to prepare elastomeric material, thoroughly solve the bloom problem that sulfuration scheme causes, prevent rubber packing material from occurring bloom quality problems.
In order to achieve the above object, taked technical scheme is:
A kind of method adopting vulcanization system to prepare elastomeric material, adopt following parts by weight of raw materials: 9 parts, second third glue, carbon black 10 ~ 13 parts, 3 ~ 4 parts, calcium carbonate, tenderizer paraffin oil 9 ~ 10 parts, 5 ~ 12 parts, anti-aging agent mixture, 0.15 ~ 0.3 part, polyethylene of dispersing agent wax, N-cyclohexyl-2-benzothiazole sulfonamide 0.15 ~ 0.3 part, ziram 0.05 ~ 0.1 part, vulcanizing agent benzoyl peroxide 0.05 ~ 0.1 part, fire retardant gathers 0.15 ~ 0.3 part, phosphorus ammonium fat;
Second third glue is placed in Banbury mixer plasticate 60 ~ 80 seconds, then anti-aging agent mixture is added mixing 30 ~ 40 seconds, add carbon black, calcium carbonate, paraffin oil, polyethylene wax banburying obtains one section of glue for 60 ~ 120 seconds, plasticate and control at 120 ~ 140 DEG C with melting temperature, one section of glue is placed in mill, add N-cyclohexyl-2-benzothiazole sulfonamide, ziram and vulcanizing agent benzoyl peroxide and fire retardant gather phosphorus ammonium fat, refining is opened even to section at 55 ~ 70 DEG C, obtain two sections of glue, by after two sections of gum formings on vulcanizer 170 ~ 185 DEG C of sulfurations within 8 ~ 10 minutes, obtain product.
Above-described anti-aging agent mixture is the mixture of zinc oxide, hard acid fat, polyoxyethylene glycol, and its weight part is: 0.5 ~ 1 part, zinc oxide, 0.1 ~ 0.3 part, hard acid fat, polyoxyethylene glycol 0.1 ~ 0.3 part.
The effect that the present invention reaches is: carry out sulfuration owing to have employed sulfur donor vulcanization system to second third glue, and this kind of method requires few to the consumption of sulphur, there will not be bloom phenomenon.
