Description
Technical field
The present invention relates to chemical field, refer to a kind of automobile interior exterior decorations Environmental-friendhot hot melt adhesive especially, the invention allows for a kind of preparation method of automobile interior exterior decorations Environmental-friendhot hot melt adhesive.
Background technology
Automobile interior exterior decorations Environmental-friendhot hot melt adhesive now used is all silicoorganic compound, epoxies and PUR substantially.Organosilicon uses dimethyl siloxane, with carry out blended through the white carbon black of hydrophobic treatment or other filler, through coupling agent and pyroprocessing, then linking agent and catalyzer etc. is added, linking agent hydrolysis after running into the moisture in air, then with in system there is crosslinking reaction, solidify to form elastomerics.PUR is free isocyano, with the reaction of moisture crosslinking curing in air, or the isocyanic ester of resting form after heat treated with moisture crosslinking curing, and form elastomerics.Epoxies is that epoxy group(ing) is through catalyzer ring-opening polymerization.
Silicone based room temperature curing type RTV, reservoir must sealed storage be forbidden and air or contact with moisture, and reservoir temperature needs lower, in order to avoid cause degraded.Its solidification is: carry out crosslinking curing from outside to inside after contact wetting, set time is about 5mm/24H(25 DEG C, 50%RH), its set time is long, winter or low its curing speed of place of northern temperature slower, release small molecules in solidification process, produce peculiar smell, cause colloid in solidification process to shrink, and its cured glue body intensity and cohesiveness all very limited, resistance to acids and bases is poor, and oil-proofness is also very poor, is therefore used in automotive field and there is significantly restriction.Epoxies solidification also needs the long period, and after its solidification, hardness is very high, easily aging, flavescence.In automobile use procedure, running into vibrations, being easy to because there is no elasticity cause colloid or zero device destruction.Like being also run into air moisture solidification, therefore also there is the problem of reservoir in PUR roughly the same RTV comparing class.Its curing speed is slower, and required time is longer, but its solidification intensity and cohesiveness will well much than RTV.Because PUR exists free isocyano before solidifying completely, comparatively large to harm, so need many European Union member countries all to limit the use of PUR.
Summary of the invention
The present invention proposes a kind of automobile interior exterior decorations Environmental-friendhot hot melt adhesive, and product has higher cohesive strength, elongation at break.Product reservoir is convenient, and construction is simple, and ageing-resistant, uv-resistance is good.Product health environment-friendly is the automobile glue that a over-all properties is very excellent.
Another object of the present invention also proposed a kind of preparation method of automobile interior exterior decorations Environmental-friendhot hot melt adhesive, and it has the resistance to deterioration of excellent cohesive strength, high temperature resistance and excellence to the component of automobile or motorcycle or being bonded and sealed of inside and outside ornaments.
Technical scheme of the present invention is achieved in that a kind of automobile interior exterior decorations Environmental-friendhot hot melt adhesive, comprises component (1), (2), (3), (4), (5), (6), (7).
Component (1) is thermoplastic elastomer, and weight part is 10-60 part, comprises SIS, SEP, SBS, SEBS, EVA, NBR.SIS is vinylbenzene, and isoprene copolymer obtains, and is segmented copolymer, and SEP is its hydrogenated products.SBS is vinylbenzene, and butadiene copolymer obtains, and is also segmented copolymer, and SEBS is its hydrogenated products.Different according to its hard functional group cinnamic ratio difference, as more larger in cinnamic ratio, elongation is less, and hardness is larger.And SBS and SEBS is generally large than the hardness of SEP and SIS, elongation is little.Their performance is also star-like with it, and linear structure is relevant, and hub-and-spoke configuration is larger than the hardness of linear structure, and elongation is low.Nitrile rubber is obtained by divinyl and copolymerization of acrylonitrile, and in like manner the ratio of hard functional group propylene cyanogen is more larger, and elongation is less, and hardness is larger.EVA is also that the identical acrylic acid ratio of reason Li Ying functional group is more larger, and elongation is less, and hardness is larger.SIS, SEP, SBS, SEBS manufacturer You Tai rubber Polymer Company, Ke Teng Polymer Company, Desco Polymer Company, Kuraray company, Sinopec Ba Ling petro-chemical corporation, ENI elastomerics company etc.The product of these companies has their own characteristics each, but difference is not very large on the whole, and the Shi Tai rubber Polymer Company that domestic use is maximum, Ke Teng Polymer Company, Sinopec Ba Ling petro-chemical corporation.The present invention uses Tai Xiang Polymer Company, the rubber of Ke Teng Polymer Company.In NBR to be nitrile rubber be a kind of synthetic rubber paracril obtained by divinyl and acrylonitrile compolymer, acrylonitrile content has 43 ~ 46%, 36 ~ 42%, 31 ~ 35%, 25 ~ 30%, 18 ~ 24% etc. five kinds.Acrylonitrile content is more, and oil-proofness is better, but winter hardiness then corresponding decline.EVA is ethene, vinyl acetate copolymer, is most widely used in hot melt adhesive, that consumption is maximum one, is commonly used to packaging industry, and this thermosol has excellent cementing property, flexibility, heating flow and dispeling cold property etc.
Component (2) is tackifying resin, weight part is 10-50 part, and the resin types of use is more, but considers based on softening temperature, the present invention uses softening temperature higher: resol, Gum Rosin, terpine resin, petroleum resin, monomer resin, bituminous resins, the one in coumarone indene resin or several arbitrarily, is less than No. 6 looks according to the selection of environment for use look.
Component (3) is filling powder, weight part is 0-20 part, comprising: white carbon black, calcium carbonate, silicon powder, talcum powder, barium sulfate, metal oxide, a kind of or several arbitrarily in nanometer polytetrafluoroethylcomposite powder, according to the difference of hot melt adhesive service requirements in the car, different filler can be selected: as needs rub resistance can select polytetrafluoroethylene powder, need heat conduction to select metal oxide etc.
Component (4) is thinner, weight part is 0-20 part, according to use and the construction temperature of product, selects different thinners, the present invention selects higher, with a kind of or several arbitrarily in the organic solvent of the good blending of thermoplastic elastomer, white mineral oil, mineral oil, mineral oil.
Component (5) is softening agent, and weight part is 0-20 part, is selected from silicone oil, paraffin, clorafin, calcium sulfate a kind of or several arbitrarily, softening agent plays and reduces construction temperature and bonding in whole product, improve processibility, but the softening temperature of product can not be reduced, affect the temperature of thermal failure.
Component (6) is antioxidant, and weight part is 0.01-3 part, the present invention selects 1076 of higher melt, 1010,168, a kind of or several arbitrarily in BHT.
Component (7) is UV absorption agent, and weight part is 0.01-3 part, UV absorption agent, selects in UV-333, UV-292, UV-348, UV-531, UV-944 a kind of or several arbitrarily.
