Automobile high-temperature silicon disulfide rubber sizing material and technology of preparing thereof

Technical field

The present invention relates to a kind of synthetic silastic material, relate to a kind of automobile high-temperature silicon disulfide rubber sizing material and technology of preparing thereof specifically.

Background technology

Synthetic silicon rubber is since last century, the forties developed successfully, and the development through seven more than ten years is perfect, now to have become in asynthetic rubber's extended familys a very important glue type.Because synthetic silicon rubber has good chemical stability and physiology inert, and kindliness is good, shape the features such as easy, make silicon rubber product have the technical characteristics such as excellent high temperature resistant, resistance to oil immersion, resistance to ozone, methanol tolerant, antifatigue, shock resistance, anti-aging, preventing deformation, high insulation, become a kind of and apply basic functional materials very widely.

China has been global maximum synthetic silicone rubber applications state now, along with scientific and technological level constantly promotes and development of the national economy sustainable and stable development, Application Areas, the quality requirements of synthetic silicon rubber product and all need will have larger expansion by quantity.Automotive industry is China's most important synthetic silicone rubber applications field, according to the preliminary statistics, existing more than 550 silicon rubber product on current automobile, use silicon rubber gross weight average each up to about 18kg; Particularly in the component such as petrol-feed pump valve seal, ignition cable, spark plug boot, heat radiation flexible pipe, gasket seal needing the special technique characteristics such as resistance to oil immersion, resistance to ethanol, high insulation, high temperature resistant, shock-resistant, antifatigue, synthetic silicon rubber is all best preferred raw materials.But because the artificial silastic elastomer industry of China is started late, throughput and state of the art limited, domestic production supply quantity only can meet about 60% of the actual expense in market, insufficient section or take from the processing of foreign procurement automobile specified silicone rubber compounds, or directly the trolley part abroad produced of import is supporting.Automobile silicon rubber product has the features such as specification is less, structural shape is complicated, and require higher to technical characteristics such as resistance to oil immersion, high temperature resistant, antifatigue, high life, therefore very strict to the material-structure performance requriements such as steady chemical structure, mechanical-physical technical feature, process for processing kindliness of the synthetic silicone rubber compounds making automobile silicon rubber product.Owing to limiting by the aspect such as technical capacity, working condition, China still can not produce automobile specified synthetic silicone rubber compounds in enormous quantities at present; The general synthetic silicone rubber compounds now used, the material-structure performance deficiencies such as molecular weight distribution ratio is wider because existing, low molecular weight volatile part content is comparatively large, multipolymer terminal hydroxy group quantity is more, make the capability and performance problems such as the long-standing chemical stability of automobile silicon rubber product is poor, mechanical and physical performance is shorter compared with work-ing life in low and high temperature environment, be not solved all the time.Therefore, develop and a kind ofly can adapt to material-structure feature such as automotive industry special having molecular weight and molecualr weight distribution appropriateness, volatile content are lower, multipolymer terminal hydroxy group comparatively small amt etc., have that chemical stability is high, mechanical-physical technical feature is strong, process for processing plasticity-kindliness is good, particularly can in envrionment temperature, work-ing life is longer more than 350 DEG C high-temperature silicon disulfide rubber sizing material, be the important topic of the artificial silastic elastomer technical field of current China.

The present invention is is conscientiously researching and analysing on China's artificial silastic elastomer technical field Shortcomings and weakness basis, form in novel material core key technology in group material structure component proportioning, fabricating technology highway route design, special technology equipment configurations etc. targetedly, take multinomial innovative technology measure, form a kind of innovation technology of preparing manufacturing out automobile high-temperature silicon disulfide rubber sizing material.

Summary of the invention

The technical problem that quasi-solution of the present invention is determined:

The present invention is directed to deficiency and the weakness of the artificial silastic elastomer sizing material technical field existence of current China, by expecting structure component proportioning in group, fabricating technology highway route design, the novel material core key technology aspects such as special technology equipment configurations, take multinomial Innovation project technical measures targetedly, solve China's automobile silicone rubber compounds wider because there is molecular weight distribution ratio, volatile content is larger, multipolymer terminal hydroxy group quantity is more waits material-structure performance deficiency, cause the chemical stability of automobile silicon rubber product poor, mechanical and physical performance is lower, envrionment temperature shorter grade in work-ing life more than 250 DEG C capability and performance technical problem.

The technical scheme that technical solution problem of the present invention is taked:

The technical problem that the present invention solves, pre-to realize by the following technical programs: research and design goes out choice for use and in matrix material, adds the compounding aid materials such as appropriate ratio crosslinking catalyst, end-blocking conditioning agent, heat-resisting Synergist S-421 95, strengthening agent, formation group material structure component proportion technique unit, be set using mixing mixed dehydration still and carry out intimate mixing rectifying and dewatering, copolymerization reactor is used to carry out high-temperature stirring copolymerzation with cross-linking, use negative pressure remover to carry out the washing of negative pressure spray silk to remove, the technology of preparing unit using continuous extruder to carry out that cooled dehydrated is extruded continuously etc. to work continuously, manufacture out one and there is molecular weight and molecualr weight distribution appropriateness, volatile content is lower, the material-structure features such as multipolymer terminal hydroxy group comparatively small amt, there is chemical stability high, mechanical-physical technical feature is strong, process for processing plasticity-kindliness is good, can in envrionment temperature, work-ing life is longer more than 350 DEG C automobile high-temperature silicon disulfide rubber sizing material, form a kind of automobile high-temperature silicon disulfide rubber sizing material technology of preparing.

Described group material structure component proportion technique unit, be according to manufacturing automobile high-temperature silicon disulfide rubber sizing material needs, formation matrix material system and compounding aid system science of carrying out selected to the technique preparation process determining to organize material structure component and consumption proportion.
