Description
Technical field
The present invention relates to a kind of chemistry painting industry that is used for the leather chemical industry industry and preparation method thereof, relate to a kind of leather flatting coating composition and preparation method thereof more specifically.
Background technology
So-called leather flatting coating is meant that a kind of viscosity is suitable, and can evenly covers leather surface by methods such as printing, roller coat, makes leather surface have the material of weak reflective or no-reflection ability.
Be coated with the last layer antiglossing pigment above the leather and leather looked have more kishke feel, more fashion; But coat antiglossing pigment the primary colors of leather is capped, thus be used for the antiglossing pigment of leather surface on the present market, otherwise dullness is good, but the transparency is poor, can not show the primary colors of leather; The transparency is good, but dullness is not enough.
Summary of the invention
The object of the present invention is to provide a kind of have simultaneously high dullness, high transparent, the good leather coating of feel.
Another object of the present invention is to provide the preparation method of this coating.
Leather flatting coating composition of the present invention, said composition is composed of the following components by weight percentage:
Polyurethane resin 35%～50% dimethyl formamide 3%～10% butanone 10%～15%
Butyl acetate 20%～30% ethyl acetate 5%～15% delustering agent 3%～6%
Hand feeling agent 0.5%～2% dispersant 0.5%～2% color spreading agent 0.5%～2%
Thickener 0～1.5%.
In aforementioned coating composition, the effect of polyurethane resin is the carrier as coating, makes other materials can be attached to leather surface; Organic solvent is dimethyl formamide (DMF), butanone (MEK), butyl acetate (BAC), ethyl acetate (EAC), plays dissolving resin, auxiliary agent, and makes it to reduce the effect of viscosity; Delustering agent is a silica dioxide delustring agent, can absorb, scattered light, plays photoextinction; Auxiliary agent has dispersant, thickener, color spreading agent, hand feeling agent; Wherein dispersant is methyl anyl alcohol, polyacrylamide, can make the delustering agent in the coating keep suspended state for a long time and not heavy fixed caking.Color spreading agent is product P T-4235, the MG-C of the chemical Co., Ltd of hand feeling agent moral modest (Shanghai), and is more gorgeous after leather printing is handled.Hand feeling agent is LA-322, HM-4930, LA-351, MA-80 for the product of the chemical Co., Ltd of moral modest (Shanghai) also, can provide various printing feels for coating, as wax sense, puckery sense, continuous sense etc.
The method for preparing coating composition of the present invention, this method comprises the steps:
1. dimethyl formamide, butanone, ethyl acetate, butyl acetate are added and disperse to add polyurethane resin then in the cylinder, stir, polyurethane resin is dissolved fully;
2. under mixture constantly stirs, slowly add delustering agent, keep stirring 60～90 minutes, it is dispersed in the system;
3. under agitation, add hand feeling agent, dispersant, color spreading agent, thickener successively, continue to stir 30～60 minutes, promptly get leather flatting coating composition.
Coating is coated in leather surface and forms a coating film, and the surface roughness and the dullness of filming are most important.The coarse more dullness in the surface of filming is good more, it is generally acknowledged that the big more film coated surface that then forms of duller particle diameter is coarse more, extinction effect is good more, the present invention finds as long as the proportion relation of selected solvent and solvent is suitable through a large amount of experiments, the duller particle of choosing than minor diameter also can reach identical extinction effect, and the duller particle of choosing than minor diameter can increase the transparency of filming greatly, the present invention chooses butanone (MEK), ethyl acetate (EAC), dimethyl formamide (DMF), these four kinds of organic solvents of butyl acetate (BAC), choosing diameter is the silica dioxide delustring agent particle of 1.2～1.8 μ m, neither influenced dullness at last, again the coating that can increase transparency greatly.
The present invention compares with the common coating in market, has characteristics widely applicable, that dullness is high, the transparency good, feel is good.Both be applicable to common leather surface treatment agent, also be applicable to high-grade leather surface processing, and effect be lasting.
The specific embodiment
Embodiment 1, gets dimethyl formamide 5% by weight, butanone 10%, butyl acetate 20%, ethyl acetate 6%, polyurethane resin 50%, particle diameter are the delustering agent silica 6% of 1.2 μ m, dispersant methyl anyl alcohol 1%, sliding sense hand feeling agent LA-322 1%, color spreading agent PT-4235 1%.The method for preparing above-mentioned flatting coating composition is:
1. dimethyl formamide, butanone, ethyl acetate, butyl acetate are added and disperse to add polyurethane resin then in the cylinder, stir, polyurethane resin is dissolved fully;
2. under mixture constantly stirs, slowly add delustering agent, keep stirring 60～90 minutes, it is dispersed in the system;
3. under agitation, add hand feeling agent, dispersant, color spreading agent, thickener successively, continue to stir 30～60 minutes, get final product to such an extent that cunning is felt antiglossing pigment.
