Abstract
The invention relates to an automobile decorative leather material surface delustering treatment agent. The formula of the delustering treatment agent comprises the following raw materials by mass: 30-50 parts of polyester resin; 4-9 parts of epoxy resin; 0.2-1 part of barium sulfate; 10-30 parts of butyl acetate; 10-30 parts of isophorone diamine; 5-15 parts of diisocyanate; and 0.3-2 parts of dimethylformamide. The delustering treatment agent provided by the invention overcomes the disadvantage that delustering of leather surfaces cannot be achieved in the prior art, and has significant advantages. Both the polyester resin and solvent used in the invention are weak solvents, the damage to leather is small, the formula is simpler, and the operation is more convenient. After delustering black leather with the delustering coating prepared by the invention, the black leather has fine handfeel, obvious fog sense and good matte properties, and is free of bright point or bright spot under light irradiation, and no bright point or bright spot appear after jacking the leather up from the back with a sharp instrument. The delustering treatment agent provided by the invention has small damage to leather when it is used for preparation of coatings, and can repair original maim defects of leather, and is convenient for delustering when used for washing leather surfaces.
Description
Technical field
The invention belongs to leatherware delustering agent technical field, specifically relates to a kind of automobile decoration leatherware material surface delustring inorganic agent.
Background technology
At present, in the case where nature, the guiding of back to nature social value theory is advocated, pursuing kishke feel becomes the main flow of field of leather development.The leather without brightness or weak brightness with kishke feel becomes current leather and prepares one of main target of industrial development.In prepared by commercial production, it is surface dulling that the leather without brightness or weak brightness prepares main technique.Existing extinction method is divided into physics delustring and chemical quenching two ways, and nowadays, physics delustring becomes the main stream approach of leather flatting.Physics delustring is to add delustering agent, coating is produced on film forming procedure surface uneven, increases to scattering of light and reduce reflection；The packing type extinction material used by which is mainly made up of metallic soap, feature fines and wax three major types.For physics delustring, leather flatting is most important with coating, and coating each component performance and content have a significant impact to extinction effect.In coating, the PU polyester resin solid content of film forming is high, can affect the transparency of thin film；Viscosity is too big or too little can affect coated technique；Molecular weight distribution width will be unable to reduce gloss degree etc..In coating, delustring powder particles are too big, can slacken the scattering to light；Flatting silica amount is too many, and coating can be made cracking after coating is dried；Very little, extinction effect is not obvious for flatting silica amount.After leatherware is using a period of time, its surface becomes easily infected by spot, dust etc., and fineness is also deteriorated, and needs the surface to leatherware to carry out fineness process.
The content of the invention
It is an object of the invention to overcome the shortcomings of that prior art is present, and design and a kind of automobile decoration leatherware material surface delustring inorganic agent is provided, can adapt to the delustring of various leather surfaces.
A kind of automobile decoration leatherware material surface delustring inorganic agent, by raw materials quality number, formula is as follows：Polyester resin 30-50；Epoxy resin 4-9；Barium sulfate 0.2-1；Butyl acetate 10-30；Isophorone diamine 10-30；Diisocyanate 5-15；Dimethylformamide 0.3-2.
The preparation method and using method of the automobile decoration leatherware material surface delustring inorganic agent, step are as follows：
（1）Polyester resin, butyl acetate, isophorone diamine, diisocyanate, dimethylformamide are added in Scattered Kettle, 10-20 minutes are stirred with blender, is added flatting silica, barium sulfate, stir 30-50 minutes with blender.
（2）Take one without delustring leather, its one end is fixed by the warp-wise along leather substrate, the appropriate product is gone up below leather fixing end, the thin film for spreading to uniform thickness is applied with scraper, the uniform leather for applying spread coated paint is placed in baking oven and is dried, oven temperature is 120-140 DEG C, drying time is 2-8 minutes, take out after drying, that is, complete leather surface delustring process.
The present invention compared with prior art, its remarkable advantage：Used by of the invention, polyester resin and solvent are all Weak solvent, and little to leather damage, formula is simpler, more convenient operation.After antiglossing pigment prepared by the present invention is to black leathers delustring, black leathers feel is fine and smooth, and substantially, sub- photosensitiveness is good for mist sense, without bright spot or speck under light irradiation, with sharp instrument from after the jack-up of the leather back side, presents without bright spot or speck.Coating is prepared with the present invention little to leather damage, the original disability defect of leather can be repaired.When cleaning to leather surface, it is easy to delustring.
