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 (in electrophoresis and other Paint Drying Oven, being heating and curing) usually.Behind the car door stiffening web gluing, during through enamelling processes such as cleanings, phosphatization, electrophoresis, anti-vibration rubber can along with the car door entry with water outlet crimp and deformation, glue-applying point is less than phenomenons such as outflow, landings.After the baking, anti-vibration rubber does not have crack performance, plays good cohesive action.Domestic present like product is relatively poor in the flexibility of enamelling processes such as cleaning, phosphatization, electrophoresis, is easy to occur degumming phenomenon.
2,, will increase the demand of high-quality anti-vibration rubber along with automobile product develops to environmental protection and energy saving, safety and comfort, lightweight, low cost, long lifetime and nuisanceless direction.Volatile organic compounds, softening agent, thinner and other auxiliary agents, deleterious filler etc. all can exist the latency to human body or environmental pollution in various degree, need when products production, to evade 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, like plasticizer phthalic acid dioctyl ester and thermo-stabilizer lead salts stablizer.And the enterprise of most domestic production tackiness agent still uses DOP and lead salts stablizer; Like the patent No. is that used softening agent is exactly a DOP in 200710072656.4 prescriptions, and thermo-stabilizer is dibasic lead stearate or tribasic Malaysia lead plumbate.
3, the used filler of most domestic manufacturing enterprise is an 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.Like used a kind of filler in the patent No. 200710072656.4 prescriptions is exactly ordinary calcium carbonate, does not also use calcium sulfate crystal whiskers.
Summary of the invention
The present invention be directed to the defective that 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 for this reason does, a kind of enhancing anti-vibration rubber with servo-actuated property, and it is characterized in that: its composition comprises:

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 impeller, evenly the back is for use 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 impeller, 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), enamelling processes such as cleaning, phosphatization, electrophoresis are had no detrimentally affect, car door and stiffening web gluing position serviceability rate are more than 98%.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, generally Diazolidinyl Urea is perhaps not allergic, to the strict control of the material of forbidding in the Industrial products.
