Description
Technical field
The present invention relates to the synthetic leather technical field of surface, particularly a kind of mist that is exclusively used in clothing leather is washed bright carbon black treatment agent and preparation method thereof.
Background technology
Leather and fur products comprises that the surface treatment mode of case and bag, clothes, footwear etc. is varied at present, the effect style changes all the time: high light Gao Gu, outermost layer of skin style, polishing style, crazy horse variable color, sheep bar etc., no matter be at surface effect, or, on feel, still pursuing imitated leather effect.
Leather material kind is a lot of in the market, constantly improve existing conventional products and on the basis of conventional products seeking breakthrough be researcher's focus.The open CN101805993A of Chinese invention patent discloses a kind of mist black surface treatment agent that is applied to synthetic leather rear section and preparation method thereof, wherein the mist black surface treatment agent is counted by weight ratio by following component and is formed: nigrosine pigment 10%～25%, fatty alcohol-polyoxyethylene ether 1%～3%, triethanolamine 3%～12%, polyurethane resin 15%～45%, flatting silica 2%～8% and surplus are dimethyl formamide.1. the preparation method of mist black surface treatment agent comprises the steps: dimethyl formamide, fatty alcohol-polyoxyethylene ether, and triethanolamine, polyurethane resin, stir, and forms pre-dispersed solvent; 2. under agitation add flatting silica, flatting silica adds speed 50～150 gram/minute, and 300～800 rev/mins of sons of mixing speed, after flatting silica all adds, under 1200～1800 rev/mins, stir 15～60 minutes, guarantees the dispersion fully of flatting silica; 3. under agitation add nigrosine pigment, nigrosine adds speed 1～5kg/ minute, 800～1200 rev/mins of mixing speeds, after nigrosine all adds, under 1200～1800 rev/mins, stir 60～120 minutes, obtain finely disseminated mist black surface treatment agent.The synthetic leather rear section product that the disclosed mist black surface treatment agent of this patent is processed, there is the goth black effect of special mist, but the synthetic leather after this finishing agent is processed seems not to be natural especially, and feel is harder, can not show a candle to the good hand touch of corium, therefore, not to be particularly suitable for clothing leather to process use.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing deficiency, provides a kind of mist that is exclusively used in clothing leather to wash bright carbon black treatment agent, and the clothing leather after the wherethrough reason not only has the black effect of extraordinary mist, and the gloss nature, soft comfortable.
The present invention also will provide a kind of mist that is exclusively used in clothing leather to wash the preparation method of bright carbon black treatment agent simultaneously, and the mist of the clothing leather of the method gained is washed bright carbon black treatment agent and not only had the black effect of extraordinary mist, and the gloss nature, soft comfortable.
For solving above technical problem, a kind of technical scheme that the present invention takes:
A kind of mist that is exclusively used in clothing leather is washed bright carbon black treatment agent, and by weight, its raw material by following weight proportion forms: 95 parts～105 parts of the yellow-stain resistant polyurethane resins that modulus is 15～35Mpa; 6 parts～8 parts of flatting silicas; 2 parts～4 parts of liquid acrylonitrile butadiene rubber; 2 parts～4 parts of polymethylphenyl siloxane fluids; 1 part～3 parts of levelling dispersants; 55 parts～65 parts of dimethyl formamides; 45 parts～55 parts of butyl acetates; 45 parts～55 parts of propylene glycol monomethyl ethers; 64 parts～68 parts of 35 parts～45 parts of isopropyl alcohols and nigrosine pigment.
According to a concrete and preferred aspect of the present invention, described mist is washed bright carbon black treatment agent and is comprised of the raw material of following weight proportion: 100 parts of the yellow-stain resistant polyurethane resins that modulus is 15～35Mpa; 7 parts of flatting silicas; 3 parts of liquid acrylonitrile butadiene rubber; 3 parts of polymethylphenyl siloxane fluids; 2 parts of levelling dispersants; 60 parts of dimethyl formamides; 50 parts of butyl acetates; 50 parts of propylene glycol monomethyl ethers; 66 parts of 40 parts of isopropyl alcohols and nigrosine pigment.
Preferably, described flatting silica is flatting silica FM14.
The another technical scheme that the present invention takes is: the preparation method that a kind of above-mentioned mist that is exclusively used in clothing leather is washed bright carbon black treatment agent: by formula, add dimethyl formamide, acetate butyl, propylene glycol monomethyl ether, isopropyl alcohol, polymethylphenyl siloxane fluid, liquid acrylonitrile butadiene rubber, levelling dispersant in yellow-stain resistant polyurethane resin, high-speed stirred is to being uniformly dispersed, then add while stirring flatting silica, treat that flatting silica stirs loose, add nigrosine pigment, fully stir by grinder and grind, obtain the described mist that is exclusively used in clothing leather and wash bright carbon black treatment agent.
According to the present invention, all raw materials are commercially available acquisition all, and raw material is easy to get.
Due to the employing of technique scheme, the present invention compared with prior art has the following advantages:
1, the clothing leather that mist according to the present invention is washed after bright carbon black treatment agent is processed not only has the black effect of extraordinary mist, and the gloss nature, soft comfortable.
2, mist according to the present invention is washed bright carbon black treatment agent good stability, can pass through roller coat, the kinds of processes such as printing are executed clothing leather are processed, applicability is wide, due to fabulous stability, also can add silicone oil auxiliary agent etc., on the basis that guarantees the black effect of mist, further improve glossy degree and smooth feel
