Abstract
The invention relates to an adhesive for bonding an EVA (ethylene vinyl acetate) foam material with a PU (polyurethane) film, as well as a preparation method and an application thereof. The adhesive is a polyurethane adhesive, and the polyurethane adhesive is prepared from the following raw materials in content by weight: 20-30% of polyester polyol, 10-15% of polyether polyol, 5-10% of diisocyanate, 1-3% of chain extender, and 50-60% of solvent. The adhesive provided by the invention is good in bonding property with the weakly-polar EVA foam material and the polar PU film, thus effectively bonding the weakly-polar EVA foam material with the polar PU film together; the adhesive is high in peel strength, simple in bonding process, and capable of being used by replacing a hot-melt adhesive and reducing the production cost in case of being applied to bonding the EVA foam material with the polar PU film.
Description
Technical field
The present invention relates to a kind of tackiness agent, be specifically related to the film adhered tackiness agent and preparation method thereof of using of a kind of eva foam material and PU.
Background technology
Known eva foam material is that polarity is lower by ethylene-vinyl acetate co-polymer foamed preparation, and PU(urethane) film belongs to high polar material, both strong difficulties of interface bonding.In the prior art, mainly adopt hot melt adhesive to bond the two, realizing the applying of the two, yet the hot melt adhesive cost is higher.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provides a kind of alternative hot melt adhesive to realize eva foam material and PU film bonding and lower-cost tackiness agent.
The present invention also will provide a kind of preparation method of described tackiness agent simultaneously.
For solving the problems of the technologies described above, a kind of technical scheme that the present invention takes is:
The film adhered tackiness agent of using of a kind of eva foam material and PU, this tackiness agent is polyurethane binder, in weight content, the composition of raw materials of described polyurethane binder is as follows: polyester polyol 20%～30%; Polyether glycol 10%～15%; Vulcabond 5%～10%; Chainextender 1%～3%; Solvent 50%～60%.
Preferably, described polyester polyol is polycarbonate diol, the combination of one or more in any diprotic acid in the diacid of selecting oneself, sebacic acid, dodecanedioic acid, the Thapsic acid and the polyester polyol that is selected from any diol reaction preparation in butyleneglycol, hexylene glycol, decanediol and the dodecanediol.The number-average molecular weight of polyester polyol is generally between 2000～6000.
Preferably, described polyether glycol is PTMG, and its number-average molecular weight is generally between 3000～6000.
Preferably, described vulcabond is for being selected from 4,4 '-'-diphenylmethane diisocyanate, tolylene diisocyanate, isoflurane chalcone diisocyanate, 4, the combination of one or more in 4 '-dicyclohexyl methyl hydride, two isocyanic acids.
Preferably, described chainextender is for being selected from one or more the combination in decanediol, dodecanediol, cyclohexane diol and 1,3 butyleneglycol.
According to the present invention, described solvent is preferably at least two kinds the combination that is selected from dimethyl formamide, toluene, dimethylbenzene, chloroform and the ethylene dichloride.
The another technical scheme that the present invention takes is: a kind of above-mentioned eva foam material and the film adhered preparation method with tackiness agent of PU, as follows: the pure and mild polyether glycol of polyester polyols that in reactor, adds formula ratio, the solvent of 30%～55% formula ratio, the chainextender of 90%～98% formula ratio, after stirring, the vulcabond that adds formula ratio, be warming up to 75～80 ℃, increase along with reaction system viscosity, the solvent that adds 30%～40% formula ratio several times, 25 ℃ of following viscosity to 60～150Pa.s of regulation system, add remaining solvent and remaining chainextender then, the cooling and stir after, packing namely gets the film adhered tackiness agent of using of described eva foam material and PU.
The present invention also is particularly related to above-mentioned eva foam material and the film adhered purposes of closing eva foam material and PU film for stickup with tackiness agent of PU.
Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
Between tackiness agent provided by the invention and low-pole eva foam material and the polarity PU film good cohesiveness is arranged all, thereby the two effectively can be bonded together, this adhesive application is when the bonding of eva foam material and polarity PU film, the stripping strength height, bonding process is simple, alternative thermosol uses, and reduces production costs.
