Abstract
The invention discloses real leather suede leather stereoscopic printing paste and a preparation method. The real leather suede leather stereoscopic printing paste is prepared by preparing polyurethane resin of sodium hydrogensulfite blocked isocyanate by polypropylene glycol, polyethylene glycol, chain extenders, trimethylolpropane, polyisocyanate, solvents, catalysts, methyl ethyl Ketoxime, sodium hydrogensulfite, ice and water, and blending the polyurethane resin with a polyurethane filming fixing agent FS-0517. According to the real leather suede leather stereoscopic printing paste and the preparation method, stereoscopic printing for real leather suede leathers can be achieved by utilizing the flat screen printing technology and drying real leather suede leathers at a temperature between 60 DEG C and 90 DEG C, a concave and convex feel is apparent, the style is elegant and fashionable, stereoscopic print patterns are specific, and the print patterns are stable, and water washing and dry friction resistant.
Description
Technical field
What the present invention relates to is a kind of corium suede printing paste, is a kind of corium suede that is used for, and realizes the slurry and the preparation method of stereoscopic printing.
The present invention is a kind of slurry of corium suede stereoscopic printing, is a kind of in 60～90 ℃ of polyurethane resin composite mortars that carry out cross-linking reaction, not network blocking; Excellent permeation property; Adhesion strength is strong, adopts common PLATE SCREAM PRINTING processing technology, just can carry out the stereoscopic printing of corium suede.
Background technology
Traditional stereoscopic printing is the suede nap stereoscopic printing, is to process through bronze designs or patterns on fans, wooden furniture, etc., cotton ginning technique, and the suede nap that can be used for bronze designs or patterns on fans, wooden furniture, etc., cotton ginning all is a science fabric.Bronze designs or patterns on fans, wooden furniture, etc., cotton ginning are to adopt the high-temperature high-pressure ironing process, are not suitable for the stereoscopic printing processing of corium suede, because; Corium is protein fibre, and shrinkage temperature is low, normally at 100～130 ℃; Surpass shrinkage temperature, protein fibre sex change, sclerosis; Harden, and the temperature of bronze designs or patterns on fans, wooden furniture, etc., cotton ginning is considerably beyond the shrinkage temperature (temperature when cotton ginning, bronze designs or patterns on fans, wooden furniture, etc. can reach more than 150 ℃) of leather.So bronze designs or patterns on fans, wooden furniture, etc., embossed technology are not suitable for the stereoscopic printing of corium suede.
At present, through market survey and document Investigation, also do not have and under 60～90 ℃ of conditions of low temperature, promptly under the shrinkage temperature of leather, to be used for the slurry that the corium suede is realized stereoscopic printing.
Summary of the invention
The purpose of this invention is to provide a kind of good penetrability that has, baking temperature is low, and promptly 60～90 ℃, below leather shrinking temperature, adhesion strength is strong, water-fast washing, anti-dry friction, the corium suede stereoscopic printing slurry and the preparation method of flower type good stability.
The preparation method of the soft suede stereoscopic printing slurry of corium of the present invention:
Raw material mass mixture ratio:
Polypropylene glycol (number-average molecular weight 1000～3000) 50～200;
Polyethylene glycol (number-average molecular weight 1000～3000) 50～200;
Chain extender: be selected from 1,2-butanediol, 1,4-butanediol, neopentyl glycol, 1, ammediol one of them or be used in combination 4～15;
Trimethylolpropane 1～6;
Polyisocyanates: be selected from toluene di-isocyanate(TDI) (TDI), 1.6-hexylidene diisocyanate (HDI), IPDI (IPDI), dicyclohexyl methyl hydride diisocyanate (H
12MDI) one of them or two or morely be used in combination 30～180;
Solvent: be selected from acetone, N-Methyl pyrrolidone, dimethyl formamide, dioxane, butanone one of them or two or morely be used in combination 40～100;
Catalyst; Be selected from dibutyl tin laurate or acetic acid dibutyl tin one of them or two kinds and be used in combination 0.02～0.06;
Be added to above-mentioned raw materials in the agitated reactor, at 60～90 ℃, the reaction time is 4～6 hours; Make base polyurethane prepolymer for use as, cool to 20～40 ℃, put into the emulsification still; Start stirring, be sequentially added into methyl ethyl ketoxime 1～4, the solution of sodium bisulfite 50～200 of mass percentage content 20%; Ice (deionized water is processed-6～-20 ℃ of ice) 100～500, deionized water at room temperature 100～500, glacial acetic acid 2～12; Stirred 20～40 minutes, and made a kind of polyurethane resin of sodium hydrogensulfite blocked isocyanate;
The above-mentioned polyurethane resin that obtains is mixed by mass ratio 80～90:10～20 with polyurethane film-forming color fixing agent FS-0517 (Liaoning Sunichem Co., Ltd.'s product), make a kind of slurry that is used for the soft suede stereoscopic printing of corium.
Concentrator of the present invention adopts common square screen printing process, just can realize the stereoscopic printing of corium suede, not network blocking; Adopt common square screen printing process, just can overwhelm pressing to the fine hair of corium suede, through 60～90 ℃ of temperature dryings; The formation concave-convex sense is obvious, elegant style fashion, the third dimension flower type of solitary characteristic; And the flower type is stable, water-fast washing, the characteristic corium suede stereoscopic printing of anti-dry friction.
Concentrator of the present invention is the heat reactivity polyurethane resin, and film forming not under the room temperature condition has extraordinary permeability, and viscosity is very big at the beginning, and adhesiveness is strong, and the property of falling suede is strong, adheres to the fine hair of suede live, and forms the tangible third dimension flower of concave-convex sense type.
The characteristics of the stereoscopic printing of corium suede, significantly concave-convex sense is carved sense, the style of bronze designs or patterns on fans, wooden furniture, etc., cotton ginning; Novel design uniqueness, aesthetic feeling and third dimension are strong, because be the corium matte, pile is nature flexibly; The mercerising sense is strong, graceful fashion, solitary characteristic; The corium suede of stereoscopic printing can be used for the decoration leather of fashion, luggage leather, clothing leather.
China's leather resource is abundant; The amount of inferior skin is bigger, through this stamp slip, the corium suede is carried out stereoscopic printing; Not only can develop the three-dimensional matte stamp leather of meeting the market requirement; And can make full use of leather resource, and become high-grade three-dimensional matte stamp leather to inferior skin, satisfy people to pursuit personalized, fashion-orientation.
