Abstract
The invention discloses a transfer-film leather material polishing-free surface treatment method. The method is characterized by: firstly preparing a surface treatment agent according to the following formula, by weight, taking 8-12% of a polyurethane adhesive with a solid content of 10-50%, 0-35% of dimethylformamide, 0-10% of cyclohexanone, 0-60% of ethyl acetate, 0-3% of dimethyl carbonate, 0-3% of methylal, 0-1% of fumed silica, 0-1% of resin able to inhibit plasticizer migration, and 25-60% of a curing agent or vulcanizing agent, subjecting all the raw materials to high-speed dispersion mixing according to the formula ratio; and then brushing a to-be-adhered surface of the transfer-film leather material with the surface treatment agent evenly, conducting drying or airing, and brushing an adhesive. The method provided by the invention has the advantages of simple structure and convenient blending, and has good popularization value.
Description
Technical field
The present invention relates to a kind of transfer-coating leather processing technology field, relate to a kind of transfer-coating leather material more specifically and exempt from surface treatment method of polishing.
Background technology
At present, the transfer-coating leather majority used both at home and abroad is formed with the double-layer fur of ox, pig first layer lether, polyurethane film-forming migration technique.Commercially available transfer-coating leather has hundreds of kind decorative pattern, color is many, lines is true to nature, kishke feel is strong, some is also furnished with luminous effect, both there is the water absorbability of corium, ventilation property and dimensional stability, there is again water-repellancy and the wear resistance of PU leatheroid, with other people fabricate-leather, the maximum difference of synthetic leather is its embryo skin is synthesized by corium fabric and natural emulsion, no matter from grammes per square metre and sense organ closest to corium, therefore various leatherware case and bag are widely used in, stationery photograph album, skin spelled by family property sofa, artificial leather automobile cushion, jewel case and process gift box, footwear material processing and other fields, cheap corium substitute products.But, in general transfer-coating leather is all the use of special oiliness brightening agent, and the coating and decorating material of transfer-coating leather itself is more special, small molecules softening agent in general brightening agent can move on transfer-coating leather, cause brightening agent decorative layer hardening, one bending will embrittlement, when bonding with other materials, the not resistance to neat solvent of Chang Yin, self force of cohesion are not enough, cause being separated between polyurethane film with embryo skin and inharmonious, need to increase technique for grinding before bonding, or to do over again benefit glue for defective goods, cause the increase of waste of human resource and goods cost.
Summary of the invention
Object of the present invention is exactly deficiency in order to solve prior art and provide can change by sticky material surface conditions, and strengthen tackiness agent to the adsorptive power of material surface, surface treatment method of polishing exempted from by the transfer-coating leather material improving adhesive effect.
The present invention adopts following technical solution to realize above-mentioned purpose: surface treatment method of polishing exempted from by a kind of transfer-coating leather material, it is characterized in that, first following formulated surface treatment agent is used, get polyurethane adhesive 8-12%, dimethyl formamide 0-35% that solid content is 10-50%, pimelinketone 0-10%, ethyl acetate 0-60%, methylcarbonate 0-3%, methylal 0-3%, gas-phase silica 0-1%, the resin 0-1% that softening agent can be suppressed to divide a word with a hyphen at the end of a line, solidifying agent or vulcanizing agent 25-60% by weight percentage, each raw material is pressed the mixing of formula ratio high speed dispersion; Then to be bonded of transfer-coating leather material evenly to be brushed with described surface treatment agent and after drying or drying, brushing adhesive stick.
Further illustrating as such scheme, this polyurethane adhesive is solvent-borne type or emulsion-type, and polyurethane content is wherein not less than 10% and not higher than 50%.
Described solidifying agent is isocyanate hardener, and in isocyanate hardener, isocyanates solid content is not less than 5%.
Described vulcanizing agent is inorganic or organically, or inorganic composite with organic vulcanizing agent; Described inorganic sulfur agent comprises Sulfur, sulfur monochloride, selenium, tellurium, and described organic sulfurizing agent comprises the promotor of sulfur-bearing, organo-peroxide, quinone oximes compound, polysulphide polymer, urethanum, maleimide derivatives.
Described transfer-coating leather material refers to not to be needed through polishing operation before upper glue, but glue rear surface film there will be localized disruption on directly, surface film can only be glued the general name of a kind of leather got off after laminating, include but not limited to transfer-coating leather, overlay film leather, multiple film leather.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
The present invention adopts before brushing adhesive stick at the surface treatment agent that the even brushing one deck of to be bonded of transfer-coating leather material is special, instead of traditional mode needed before transfer-coating leather bonding through technique for grinding, therefore and the rework rate caused is high, the problem such as waste of human resource and the increase of goods cost solve, and can effectively improve transfer-coating leather bonding strength.
