Abstract
The invention discloses a preparation technology of environmental friendly silicone rubber, and relates to the field of the preparation technology of silicone rubber. The preparation technology comprises four processing steps: preparation of masterbatch, preparation of a mixture A, microwave vulcanization and finishing a product. The preparation technology of the environmental friendly silicone rubber has the advantages that the processing flow is simple and convenient, the produced product is good in quality and high in abradability, the production cost is saved, the price of raw materials is low, the performance is good, the clean use and environment protection can be realized, and the needs of the majority of users can be met; the environmental friendly silicone rubber has good mechanical property, no emissions of pollutants and heat when the environmental friendly silicone rubber is prepared, has the characteristic of green environmental protection, and the preparation rate is more than 98%.
Description
Technical field
The present invention relates to the preparing technical field of rubber, be specifically related to a kind of preparation technology of environment-friendly silicon rubber.
Background technology
Growing and universal along with automobile, automobile associated components have also been obtained significant progress.As isolation compartment and extraneous major parts, the effect of weather strip for automobile is also remarkable all the more.Usually require that sealed strip has good sound insulation, dust-proof, vibration damping and sealing property, in prior art, weather strip for automobile generally adopts Ethylene Propylene Terpolymer rubber (EPDM) to be made, Ethylene Propylene Terpolymer rubber (EPDM) has excellent weather resistance and outstanding processing characteristics, be made into its good seal performance after sealed strip, excellent mechanical.But because Ethylene Propylene Terpolymer rubber (EPDM) gasket structure is closely knit, therefore usually become closely knit glue sealed strip, sound insulation and the effectiveness in vibration suppression of closely knit glue sealed strip are not good yet.In order to improve sound insulation and the damping property of weather strip for automobile, closely knit glue and gelatin sponge are combined into one by external employing, obtain compound sealing strip, this compound sealing strip has good sound insulation and effectiveness in vibration suppression, good airproof performance simultaneously, silicon rubber is the silicone elastomer occurred in a kind of sixties, and it at room temperature can solidify on the spot without the need to heating or pressurization, is just widely used does seal gum use once appearance.Meanwhile, silicon rubber also has excellent insulativity, weathering resistance, moistureproofness, shock resistance, crushing resistance and physiological inertia, is widely used in the fields such as building, automobile, electronics, chemical industry, machinery, aerospace, medicine equipment.But containing a large amount of C and H in silicon rubber, this causes silicon rubber easy firing, its fire prevention, high temperature resistant, anti-creeping poor performance.Above-mentioned defect greatly limit the use range of silicon rubber, simultaneously that rubber will be gone to possess physicochemical property is good for prior art, there is the feature of the very strong aspect such as heat-resisting, water-fast, corrosion-resistant, ageing-resistant, so in the production process of rubber product, the requirement of its process production techniques is higher, but the preparation method of existing rubber is comparatively complicated, produce seriously polluted and preparation rate is lower.
Summary of the invention
It is wide that problem to be solved by this invention is to provide a kind of industrial use, environmental friendliness, long-lived a kind of environment-friendly silicon rubber.
To achieve these goals, the present invention technical scheme of taking is the preparation technology of a kind of environment-friendly silicon rubber provided.Comprise the steps:
(1) preparation of rubber master batch: the mixture containing Ethylene Propylene Terpolymer rubber 5-7 part, polyoxyethylene glycol 10-13 part, vulcanizing agent 6-9 part, tenderizer 14-18 part and weighting agent 4-5 part is carried out mixing, obtains rubber master batch.
(2) preparation of mixture A: add vitrified color sand 60-80%, clear aqueous emulsion 8-15%, thickening material 6-12%, auxiliary agent 5-10% in stirrer, carries out smashing and stirring, obtains mixture A.
(3) microwave vulcanization: by described rubber master batch, mixture A, α, alpha, omega-dihydroxy polydimethyl siloxane 12-15 part and the mixing of low viscous silicone oil 25-30 part, after stirring, row's bubble, then carries out microwave vulcanization.
(4) finished product: again stirred at 25 DEG C by the mixture after microwave vulcanization, be then cooled to room temperature, obtains required a kind of environment-friendly silicon rubber.
Preferably, the flash-point of described step (1) polyoxyethylene glycol is 165-180 DEG C.
Preferably, the churning time of described step (2) is 45-50min, and whipping temp is 20-25 DEG C.
Beneficial effect of the present invention: a kind of environment-friendly silicon rubber work flow of the present invention is simple and convenient, the good product quality produced and fastness to rubbing strong, save production cost, and low in raw material price, performance is good, clean environment firendly, meet the demand of users, the good mechanical performance of this kind of rubber, when preparing it, there is no the discharge of pollutent and heat, there is the feature of environmental protection, and preparation rate reaches more than 98%.
Embodiment
The technique means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
Embodiment 1:
(1) preparation of rubber master batch: the mixture containing Ethylene Propylene Terpolymer rubber 6 parts, polyoxyethylene glycol 12 parts, vulcanizing agent 8 parts, tenderizer 16 parts and weighting agent 5 parts is carried out mixing, obtains rubber master batch.
(2) preparation of mixture A: add vitrified color sand 70%, clear aqueous emulsion 10%, thickening material 12%, auxiliary agent 8% in stirrer, carries out smashing and stirring, obtains mixture A.
(3) microwave vulcanization: by described rubber master batch, mixture A, α, alpha, omega-dihydroxy polydimethyl siloxane 13 parts and low viscous silicone oil 28 parts mixing, after stirring, row's bubble, then carries out microwave vulcanization.
(4) finished product: again stirred at 25 DEG C by the mixture after microwave vulcanization, be then cooled to room temperature, obtains required a kind of environment-friendly silicon rubber.
