Abstract
The invention relates to a leather surface matting agent. The leather surface matting agent is characterized by being composed of resin, fumed silica, paraffin, ethyl acetate, toluene, butanone 5-15 and a silane coupling agent. The leather surface matting agent belongs to the technical field of leather matting agents, and concretely relates to a leather surface matting agent, and a preparation method and a usage method thereof. The leather surface matting agent overcomes the disadvantages that in the prior art a leather surface cannot be matted, and possesses substantial advantages. Resin and a solvent employed by the leather surface matting agent are both weak solvent type, and the leather surface matting agent is small in damage to leather, relatively simple in formula and relatively convenient to operate. After the prepared matting agent is used to matt black leather, black leather is fine in handfeel, obvious in fog feeling and good in matt property, does not have bright spots or bright speckles under radiation of light, and does not have bright spots or bright speckles after being jacked from the backside of leather. The prepared matting agent is small in damage to leather, can repair leather original injury defects, and is convenient for matting leather when the leather surface is cleaned.
Description
technical fieldthe present invention relates to a kind of leather surface matting agent, it is characterized in that being made up of following: resin, aerosil, paraffin, ethyl acetate, toluene, butanone 5-15, silane coupling agent.This invention belongs to leatherware matting agent technical field, more specifically relates to a kind of leather surface matting agent and preparation and application thereof.
background technologyat present, under the guiding of uphold nature, back to nature social value theory, pursue the main flow that kishke feel becomes field of leather development.The leather without brightness or weak brightness with kishke feel becomes one of current leather major objective preparing industrial development.In industrial production preparation, 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 kinds of modes, and nowadays, physics delustring becomes the main stream approach of leather flatting.Physics delustring adds matting agent, makes coating produce uneven on film process surface, increases scattering of light and reduce reflection.The packing type extinction material that it uses is formed primarily of metallic soap, functional fines and wax three major types.For physics delustring, leather flatting coating is most important, and each component property of coating and content have a significant impact extinction effect.In coating, the PU resin solid content of film forming is high, can affect the transparency of film, and viscosity is too large or too littlely can affect coated technique, and molecular weight distribution is wide cannot reduce glossiness etc.In coating, flatting silica particle is too large, can slacken the scattering to light.Flatting silica amount is too many, and coating can be made after coating drying to occur cracking.Very little, extinction effect is not obvious for flatting silica amount.After leatherware uses for some time, its surface becomes easily infected by spot, dust etc., and smooth finish is also deteriorated, and needs to carry out smooth finish process to the surface of leatherware.
summary of the inventionthe object of the invention is to the deficiency overcoming prior art existence, and design provides a kind of leather surface matting agent and preparation and application thereof, can adapt to the delustring of various leather surface.In order to achieve the above object, this invention takes following technical scheme:
A kind of leather surface matting agent, by raw materials quality number, fills a prescription as follows: resin 30-50, aerosil 4-9, paraffin 0.2-1, ethyl acetate 10-30, toluene 10-30, butanone 5-15, silane coupling agent 0.3-2.
Wherein, resin is self-control solvent borne polyurethane sizing agent, and this self-control solvent borne polyurethane sizing agent synthesizing formula by raw materials quality part is: polyester diol 50-150, vulcabond 20-50, isophorone diamine 2-10, butyleneglycol 3-8, Virahol 3-10, organo-bismuth 0.15-0.25, toluene 100-150, dimethyl formamide 100-190.
The preparation method of this leather surface matting agent and using method, step is as follows:
(1) resin, ethyl acetate, toluene, butanone, silane coupling agent are joined in Scattered Kettle, stir 10-20 minute with stirrer, then add flatting silica, paraffin, stir 30-50 minute with stirrer.
(2) one is got without the leather of delustring, its one end is fixed by the warp-wise along leather substrate, these goods appropriate are gone up below leather inboardend, the film spreading to uniform thickness is coated with scraper, the leather being evenly coated with spread coated paint is placed in baking oven dry, oven temperature is 120-140 DEG C, and time of drying is 2-8 minute, take out after dry, namely complete leather surface delustring process.
Compared with prior art, its remarkable advantage: the present invention's resin used and solvent are all Weak solvent, little to leather damage, formula is simpler, more convenient operation in the present invention.Flat paint prepared by the present invention is to after black leathers delustring, and black leathers feel is fine and smooth, and mist sense is obvious, and sub-photosensitiveness is good, without bright spot or speck under irradiate light, by sharp instrument after the jack-up of the leather back side, presents without bright spot or speck.Prepare coating with the present invention little to leather damage, can repair the original disability defect of leather.When cleaning leather surface, be convenient to delustring.
