Abstract
The invention provides a kind of hot printing adhesive for leather full wiped film, comprise by weight: vibrin 10-30, chloroprene rubber resin 5-15, tackifying resin 1-5, mineral filler 2-10, organic mixed solvent 50-80.This gum has excellent bond performance to aluminium lamination and transfer vector leather, the paper etc. of full commentaries on classics film; Blanching Yin Wendu is lower, and hot pressing temperature is in the time of 90 ℃, and tackiness agent promptly has well softening adhesive property; Used solvent polarity a little less than, only used ketones solvent seldom, aluminium lamination and pigmented layer are not had corrosion substantially.
Description
Technical field
The present invention relates to tackiness agent, belong to the organic polymer heat-activatable adhesive, specifically is a kind of hot printing adhesive for leather full wiped film and preparation method thereof.
Background technology
Leather total transfer film is the leather bronzing pad pasting again, is the abbreviation of leather with the gold stamping pad pasting of entire transformation or comprehensive gold stamping pad pasting of transcription.The full film that changes has six layers of structure, is respectively the PET film, parting agent, protective layer, pigmented layer, aluminium coated and gum layer (as shown in Figure 1).
Leather total transfer film carries out heat posted by heating and pressurizing and synthetic leather, PU skin and corium and closes, the PET film of while stripper surface, thus make coating or pattern on the PET film all transfer to leather surface.Full commentaries on classics film and leather hot pressing are compounded to form the transfer skin, shift skin as an emerging product in the leather, are widely used in a plurality of fields such as footwear material, case and bag, clothing.The development in recent years impetus is swift and violent, is to continue the trend of selling well on market.
Shift skin and compare with common leather, it has the distinctive metalluster sense that common leather changes colour and do not had by padding.Its gloss vividness, wear resistance, and anti-solvent corrosion all improves a lot.
At present, change the used blanching seal gum of film entirely, mainly have the problem of two aspects:
1, its softening temperature is higher, and generally all about 120 ℃, use temperature requires 130 ℃ even higher.So high use temperature has just been brought some problems thus: for example the pigmented layer reaction is not to talk about very completely, and its temperature tolerance is just poor so.If the too high meeting of use temperature impels the host of pigmented layer and solidifying agent further to participate in reaction, the urethane of protective layer also can soften mobile simultaneously.Thereby cause the softening migration of aluminium lamination.The glossiness of full commentaries on classics film is reduced greatly, even cause serious loss of gloss phenomenon.Whole volume film is all scrapped, caused loss greatly and waste.
2, because its main resin is a urethane resin.Urethane resin is difficult with dissolving, so urethane resin all is the strong polar solvents that form with pimelinketone, butanone and the collocation of a spot of butyl ester.When gum coating, the solvent in the tackiness agent is easy to the infiltrate aluminium coated, and corrodes the coating of pigmented layer and protective layer, thereby causes the loose colour of full commentaries on classics film color and grow dim, and seriously influences the surface effect that shifts skin.
Summary of the invention
It is lower to the purpose of this invention is to provide a kind of use temperature, hot printing adhesive for leather full wiped film that solvent polarity is more weak and bond properties is excellent and preparation method thereof.
Hot printing adhesive for leather full wiped film provided by the invention, meter comprises by weight: vibrin 10-30, chloroprene rubber resin 5-15, tackifying resin 1-5, mineral filler 2-10, organic mixed solvent 50-80.
Described vibrin is a saturated polyester resin.It is a kind of spherical particle of colourless or white grain of rice size, weight-average molecular weight 18000-25000, about 80 ℃ of softening temperatures, OH value 1-4mgKOH/g.
Described chloroprene rubber resin, outward appearance are creamy white to beige or light brown sheet or block, weight-average molecular weight 80000-120000, about 80 ℃ of softening temperatures.
Described tackifying resin is selected from a kind of in oil tackifying resin, Gum Rosin and the terpenes tackifying resin, preferred terpenes tackifying resin.Its outward appearance is little yellow sheet or blocks of solid particle, acid number 1.0-4.0mgKOH/g, saponification value 1.0-5.0mgKOH/g, iodine number 40-75, toluene insolubles≤0.05%.
Described mineral filler is selected from one or both in talcum powder, lime carbonate, barium sulfate, kaolin and the titanium dioxide, the mixture of preferred titanium dioxide and lime carbonate, and the ratio of titanium dioxide and lime carbonate is 1/1-2/1.
Described organic mixed solvent is selected from pimelinketone, butanone, dimethylbenzene, toluene, butylacetate, ethyl acetate and alcoholic solvent, the mixed solvent of preferred butanone, butylacetate and toluene, and their weight ratio is butanone/butyl ester/toluene=3/4/3.This mixed solvent is solvent adhesive resin fully both, can not cause too big corrosion to the figure layer of full commentaries on classics film front again.
The preparation method of hot printing adhesive for leather full wiped film provided by the invention may further comprise the steps:
(1) in reactor, adds butanone and butylacetate in proportion, stir, be warmed up to 60 ℃;
(2) add vibrin, chloroprene rubber resin and terpenes tackifying resin successively, be incubated 60 ℃ and stir and to dissolve fully to resin in two hours;
(3) and then add mineral filler, be stirred to and be uniformly dispersed;
(4) add toluene solution at last, stir, the leather that makes the 30%-50% solids content is lowered the temperature discharging, packing with the full film blanching seal gum that changes.
Compared with prior art, hot printing adhesive for leather full wiped film of the present invention has the following advantages:
1, aluminium lamination and transfer vector leather, the paper etc. to full commentaries on classics film have excellent bond performance;
2, blanching Yin Wendu is lower, and hot pressing temperature is in the time of 90 ℃, and tackiness agent promptly has well softening adhesive property;
3, used solvent polarity a little less than, only used ketones solvent seldom, aluminium lamination and pigmented layer are not had corrosion substantially.
