Description

Furniture item surface leather flatting inorganic agent

Technical field

The invention belongs to leatherware delustering agent technical field, specifically relate to a kind of furniture item surface leather flatting inorganic agent.

Background technology

At present, under the guiding advocating nature, back to nature social value theory, pursuing kishke feel becomes the main flow of field of leather development.The leather without brightness or weak brightness with kishke feel becomes one of current leather main target preparing industrial development.In prepared by commercial production, preparing main technique without the leather of brightness or weak brightness is surface dulling.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, makes coating produce on film forming procedure surface uneven, increases scattering of light and reduces reflection；The packing type extinction material that it is used mainly is made up of metallic soap, functional fines and wax three major types.For physics delustring, leather flatting coating is most important, and extinction effect is had a significant impact by each component property of coating and content.In coating, the PU esters of silicon acis solid content of film forming is high, can affect the transparency of thin film；Viscosity is the biggest or the least can affect coated technique；Molecular weight distribution width will be unable to reduce glossiness etc..In coating, flatting silica granule is too big, can slacken the scattering to light；Flatting silica amount is too many, and coating can be made the most cracking in coating；Very little, extinction effect is inconspicuous for flatting silica amount.After leatherware uses 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.

Summary of the invention

It is an object of the invention to the deficiency overcoming prior art to exist, and design a kind of furniture item surface of offer leather flatting inorganic agent, can adapt to the delustring of various leather surface.

A kind of furniture item surface leather flatting inorganic agent, by raw materials quality number, formula is as follows: esters of silicon acis 30-50；Sodium silicate 4-9；Sodium acetate 0.2-1；Ethyl acetate 10-30；Toluene 10-30；Acetone 5-15；Cross-linking agent 0.3-2.

Wherein, esters of silicon acis is self-control solvent borne polyurethane adhesive, and this self-control solvent borne polyurethane adhesive synthesizing formula by raw materials quality part is: polyester diol 50-150；Diisocyanate 20-50；Isophorone diamine 2-10；Butanediol 3-8；Isopropanol 3-10；Organo-bismuth 0.15-0.25；Toluene 100-150；Dimethylformamide 100-190.

The preparation method of this furniture item surface leather flatting inorganic agent and using method, step is as follows:

(1) esters of silicon acis, ethyl acetate, toluene, acetone, cross-linking agent are joined in Scattered Kettle, stir 10-20 minute with blender, add flatting silica, sodium acetate, stir 30-50 minute with blender.

(2) one is taken without the leather of delustring, its one end is fixed by the warp-wise along leather substrate, these goods appropriate are gone up below the fixing end of leather, the thin film spreading to uniform thickness it is coated with scraper, the leather being uniformly coated with spread coated paint is placed in baking oven drying, and oven temperature is 120-140 DEG C, and drying time is 2-8 minute, dried taking-up, i.e. completes leather surface delustring and processes.

Compared with prior art, its remarkable advantage: esters of silicon acis used by the present invention and solvent are all Weak solvent, little to leather damage, formula is simpler, more convenient operation for the present invention.After antiglossing pigment prepared by the present invention is to black leathers delustring, black leathers feel is fine and smooth, and mist sense is obvious, and sub-photosensitiveness is good, without bright spot or speck under light irradiates, by sharp instrument after the jack-up of the leather back side, presents without bright spot or speck.Preparing coating by the present invention little to leather damage, disability defect original to leather can be repaired.When leather surface is cleaned, it is simple to delustring.
