Abstract
The invention provides automobile paste high-expansion vibration-reduction and sound-insulation rubber and a manufacturing process thereof. Butadiene rubber, EVA, liquid butyronitrile, rubber oil, epoxy resin, polyisobutene, nano activated calcium carbonate, a foaming agent, sulfur, an accelerating agent, a rust inhibitor, a vulcanizing agent, a plasticizer and a tackifier are selected and used, and a pressure kneader is used for mixing the dispersed materials. The rubber is spread on corresponding parts of steel plates in an automobile body welding workshop by a glue spreading pump; the rubber passes through a painting shop after automobile body welding, is heated with an electrophoretic paint drying line to foam to fill up an entire cavity, and achieves the effects of vibration reduction, sound insulation, dust separation and dust prevention.
Description
Technical field
The present invention relates to the automotive material technical field, re-entrant portion for the two block plates formation of three columns of automobile, or between ceiling outside plate and stiffening web, also can be used in vehicle body due to the position, gap produced between the rear inner and outer plates of welding, relate in particular to automobile paste high expansion shock-absorption sound-insulation glue and manufacture craft thereof.
Background technology
Car industry is in order to pursue the automobile of peace and quiet, comfortable, environmental protection, will cut off the noise that all re-entrant portions of vehicle body bring, the noise and the dust that bring from outside air of A, B, a C3 column particularly, these cavitys and column again can not be in the workshop shutoff that is welded, when vehicle body was crossed pre-treatment and electrophoresis line body, liquid will be from these cavity inflow and outflows, if shutoff after having crossed pre-treatment and electrophoresis line body, cavity is soldered, and material can't be put into cavity.The past people require lower to the car load comfortableness, a lot of cars do not focus on processing this problem, and along with the raising that client requires car comfort, car load factory more and more pays close attention to this problem.At present, automobile industry designer is widely used two kinds, the first is expansive niggerhead material after heating, and the second is the paste material of two components, although this bi-material can have certain effect, but defect is separately arranged respectively, the first material is bulk material, and the technique more complicated is not easy to automatic production and automated construction, and the quality guaranteed period is shorter, is unfavorable for long-distance transport and uses.The second material is two-component materials, needs special preparation of construction, and cost is higher, and Flame Retardancy is poor, is unfavorable for that big area is used on automobile.How just can overcome the above problems, and just can construction operation with common gluing pump in auto vendor.
Summary of the invention
In order to overcome the problem of prior art, the invention provides automobile paste high expansion shock-absorption sound-insulation glue and manufacture craft thereof, the smooth gluing of the enough common gluing pumps of energy, rate of expansion reaches the standard-required of current bulk material, reduce production cost and construction cost, overcome the disadvantage of this bi-material of current automobile industry use.
Technical scheme of the present invention is: automobile paste high expansion shock-absorption sound-insulation glue and manufacture craft thereof, select cis-1,4-polybutadiene rubber, EVA, nitrile (HTBN), rubber oil, epoxy resin, polyisobutene, nm-class active calcium carbonate, whipping agent, sulphur, promotor, rust-preventive agent, vulcanizing agent, softening agent, tackifier to use the pressurization kneader, the blending dispersion material is below the weight ratio of this material:
Manufacturing process steps is as follows: the first step: proportioning was put in Banbury mixer to banburying 10 minutes by cis-1,4-polybutadiene rubber and EVA, puts into rubber oil minutes for three times, make it softening, material mixing is even, without small-particle;
Second step: the material mixed is put in kneader, added nitrile (HTBN), mediated 10 minutes in kneader, then drop into nm-class active calcium carbonate, mediated 5 minutes, divide and slowly put into polyisobutene 3 times, guarantee that kneading process is without fine particle;
The 3rd step: when the kneader temperature is reduced to below 40 ℃, add whipping agent, sulphur, promotor, rust-preventive agent, vulcanizing agent, add softening agent to mediate evenly after mixing;
The 4th step: the viscosity according to product, add tackifier, adjust viscosity, viscosity is adjusted to 1000-1600 ten thousand CP (0.5RPM);
The 5th step: then vacuum 1 hour is packaged into the specification quantity of regulation.
The invention has the beneficial effects as follows: be convenient to the automatic production of auto vendor, the material phenomenon of not trickling, and can meet the performance requriements of the overseas assembling of domestic production.
Embodiment
Automobile paste high expansion shock-absorption sound-insulation glue and manufacture craft thereof, by cis-1,4-polybutadiene rubber, EVA, nitrile (HTBN), rubber oil, epoxy resin, polyisobutene, nm-class active calcium carbonate, whipping agent, sulphur, promotor, rust-preventive agent, vulcanizing agent, softening agent, tackifier, use the pressurization kneader, the blending dispersion material is below the weight ratio of this material:
Manufacturing process steps is as follows: the first step: proportioning was put in Banbury mixer to banburying 10 minutes by cis-1,4-polybutadiene rubber and EVA, puts into rubber oil minutes for three times, make it softening, material mixing is even, without small-particle;
Second step: the material mixed is put in kneader, added nitrile (HTBN), mediated 10 minutes in kneader, then drop into nm-class active calcium carbonate, mediated 5 minutes, divide and slowly put into polyisobutene 3 times, guarantee that kneading process is without fine particle;
The 3rd step: when the kneader temperature is reduced to below 40 ℃, add whipping agent, sulphur, promotor, rust-preventive agent, vulcanizing agent, add softening agent to mediate evenly after mixing;
The 4th step: the viscosity according to product, add tackifier, adjust viscosity, viscosity is adjusted to 1000-1600 ten thousand CP (0.5RPM);
The 5th step: then vacuum 1 hour is packaged into the specification quantity of regulation.
Corresponding site at car body welding shop steel plate is smeared this material with gluing pump, and after car body welding, along with the electrophoresis baking finish line, the post-foaming that is heated, fill full whole cavity through painting hall, plays vibration damping, dust-separation, dustproof effect.The present invention adds rust-preventive agent, guarantee on the rear adhesive surface of material foaming not get rusty phenomenon, the use of nano modified material and softening agent by good operability, make the paste material be convenient to smear, difficult drop-off again after smearing, and high rate of expansion reaches the standard-required of current bulk material, production cost and construction cost have been reduced.
