Description
Technical field
The present invention relates to chemical material field, specifically is a kind of enhancing anti-vibration rubber with servo-actuated property and preparation method thereof.
Background technology
1, strengthens outside plate and the isolation between the stiffening web and bonding that anti-vibration rubber is mainly used in arrangements for automotive doors, engine shield, luggage-boot lid.Strengthen in the structure of automobile, sealing is antirust, vibration and noise reducing, heat insulation noise reduction, firm locking, internal and external ornament, and simplified manufacturing technique, alleviate aspect such as tare play a part special.Anti-vibration rubber and pasta steel plate have good tack, anti-vibration rubber can fully extend and flexible during stickup, the tackiness agent of pasting on the vehicle-body outer panel face of back does not have separation phenomenon, need not to set up specially the equipment of being heating and curing (being heating and curing in electrophoresis and other Paint Drying Oven) usually.Behind the car door stiffening web gluing, during through enamelling processes such as cleanings, phosphatization, electrophoresis, anti-vibration rubber can the deformation along with car door entry and water outlet crimp, phenomenons such as not outflow of glue-applying point, landing.After the baking, anti-vibration rubber does not have crack performance, plays good cohesive action.Domestic present like product is relatively poor in the adaptability of enamelling processes such as cleaning, phosphatization, electrophoresis, is easy to occur degumming phenomenon.
2, along with automobile product develops to environmental protection and energy saving, safety and comfort, lightweight, low cost, long lifetime and nuisanceless direction, will increase the demand of high-quality anti-vibration rubber.Volatile organic compounds, softening agent, thinner and other auxiliary agents, harmful filler etc. all can exist the latency to human body or environmental pollution in various degree, need evade when products production these objectionable impuritiess.The well-known automobile production of more external of being correlated with enterprise has the hazardness material that clearly regulation is arranged to out of use, as plasticizer phthalic acid dioctyl ester and thermo-stabilizer lead salts stablizer.And domestic most of enterprise that produces tackiness agent still uses dioctyl phthalate (DOP) and lead salts stablizer, as the patent No. be 200710072656.4 the prescription in used softening agent be exactly dioctyl phthalate (DOP), thermo-stabilizer is dibasic lead stearate or tribasic Malaysia lead plumbate.
3, the used filler of domestic most of manufacturing enterprise is ordinary calcium carbonate with low cost, and it is compared with modified nano calcium carbonate, and is all inferior a lot of aspect hydrophobicity, flowability, dispersiveness and oil-absorption(number).Evident difference can appear in the product that application ordinary calcium carbonate and nano-calcium carbonate make, and contains higher application property, the relatively poor phenomenons such as (having solvent to separate out) of package stability of influencing of product viscosity of ordinary calcium carbonate.The filler that adds calcium sulfate crystal whiskers can significantly improve intensity, the resistance to elevated temperatures of product.Be exactly ordinary calcium carbonate as used a kind of filler in the patent No. 200710072656.4 prescription, also do not use calcium sulfate crystal whiskers.
Summary of the invention
The present invention be directed to the defective that the above-mentioned background technology exists and improve, enhancing anti-vibration rubber that a kind of environment-friendly type has servo-actuated property and preparation method thereof is provided.
Technical scheme of the present invention is for this reason, a kind of enhancing anti-vibration rubber with servo-actuated property, and it is characterized in that: its composition comprises:

Pigment 0.2～2.5%
Wherein the modified vinyl resin is bisphenol type Vinylite or phenolic aldehyde epoxy type vinyl ester resin.
Thermoplastic resin is polyvinyl resin or polyvinyl chloride (PVC) RESINS.
Toughner is unsaturated end group response type liquid acrylonitrile butadiene rubber, and its model is ETBN-EP.
Thinner is a-vinyl toluene or Rocryl 410.
Softening agent is epoxy ester series, alkyl sulfonates, as the epoxy soybean wet goods.
Coupling agent is the r-aminopropyl triethoxysilane.
Solidifying agent is methylethyl ketone peroxide.
Promotor is cobalt naphthenate.
Filler is modified nano calcium carbonate, active micro silicon powder, calcium sulfate crystal whiskers, calcium oxide or its composition.
Thermo-stabilizer is mixed metal stabilizer, organotin stabilizer.
Whipping agent is azo-compound, sulfonyl hydrazines compound, as AC whipping agent etc.
Pigment is colour carbon black.
A kind of preparation method with enhancing anti-vibration rubber of servo-actuated property, it is characterized in that: this method may further comprise the steps:
1) 20～35% modified vinyl resins, 10～30% thermoplastic resins, 4～35% softening agent, 0.5～6% thinner and 1～12% toughner are stirred 30min～60min in homogenizer, evenly the back is stand-by to mixing of materials.
2) above-mentioned 1) add 2～6% solidifying agent, 1～5% promotor, 0.4～5.5% coupling agent, 1～6% thermo-stabilizer, 0.5～5% whipping agent, 15～35% fillers and 0.2～2.5% pigment in the material that mixes and add stirring 30～90min in the homogenizer, even to mixing of materials.
3) with above-mentioned 2) material that mixes crosses twice of three-roll grinder or three times, discharging, packing.
Beneficial effect:
Enhancing anti-vibration rubber with servo-actuated property of the present invention has good application property, the mechanical pump that can be used on the weld car line is carried, anti-vibration rubber and pasta steel plate have good tack and servo-actuated property, usually need not to set up specially the equipment of being heating and curing (in electrophoresis and other Paint Drying Oven, being heating and curing), without any detrimentally affect, car door and stiffening web gluing position serviceability rate are more than 98% to enamelling processes such as cleaning, phosphatization, electrophoresis.The room temperature storage phase can reach more than half a year, and after long-term storage or the long period transportation, even the parts of coating anti-vibration rubber are toasted, the tackiness agent on the vehicle-body outer panel can not peeled off, and bounding force significantly reduces and metamorphism, and the surface can not deform yet.
Enhancing anti-vibration rubber with servo-actuated property of the present invention has the feature of environmental protection, does not have peculiar smell and toxicity, if tackiness agent touches skin, general Diazolidinyl Urea or allergic not is to the strict control of the material of forbidding in the Industrial products.
