Abstract
The invention discloses a water-based PU artificial leather with a stereoscopic impression pattern. The artificial leather comprises a base cloth layer, a polyurethane PU layer coated on the base cloth layer, an aqueous polyurethane adhesive layer coated on the polyurethane PU layer, an aqueous PU resin layer coated on the aqueous polyurethane adhesive layer, modified polyurethane resin coated on the aqueous PU resin layer, crystal resin coated on the modified polyurethane resin and high solid polished resin coated on the crystal resin. The aqueous PU resin layer of the artificial leather provided by the invention is subjected to post high temperature PU treatment at 190 DEG C to gain strong concavo-convex crystal stereoscopic impression, better stereoscopic impression and unique effect. The high solid polished resin is a PU artificial leather post treatment resin with high solid content, and has characteristics of high gloss and high brightness; and the high solid polished resin cooperates with the crystal resin mutually to obtain synthesized leather with advantages of smoothness, scratch resistance and strong sense of cashmere.
Description
Technical field
The present invention relates to a kind of PU artificial leather, be specifically related to a kind of third dimension decorative pattern that has, have the artificial leather of strong stereoscopic visual effect.
Background technology
At present, the artificial leather product becomes following popular trend gradually, and artificial leather has been widely used in products such as producing case and bag, clothes, footwear.The base fabric of PU leather is the good canvas PU material of tensile strength, except can being coated in base fabric top, in the middle of base fabric can also being included in, make it outward appearance and can't see the existence of base fabric, it is good that the PU leather has physical property, anti-complications, pliability is good, tensile strength is large, have gas permeability, so the PU leather is widely used in the fabric of footwear or the position that case and bag bear weight.In order to make artificial leather can satisfy people to the demand of break and pattern, often to carry out the embossing treatment process to artificial leather, make the irregular crystal-feel three-dimensional pattern of leather surface tool of artificial leather.In the prior art, artificial leather is carried out the embossing processing have a lot of technical difficulties, the pattern poor visual effect that obtains is processed in embossing, and embossed technology needs equipment many, and cost is higher, processes the pattern retention time that obtains through stamp simultaneously shorter, fugitive color does not satisfy people to high-level requirement.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of obvious third dimension decorative pattern that has is provided, and has the artificial leather of strong stereoscopic visual effect.
Technical scheme: for solving above technical problem, the present invention takes following technical scheme:
A kind of water-based PU artificial leather with third dimension decorative pattern, it comprises base cloth layer, be coated in polyurethane PU layer on the described base cloth layer, be coated in aqueous polyurethane tack coat on the polyurethane PU layer, be coated in water-based PU resin bed on the aqueous polyurethane tack coat, be coated in the modified polyurethane resin on the water-based PU resin bed, is coated in the crystal-feel resin on the modified polyurethane resin and is coated in solid bright resin of height on the crystal-feel resin.
Wherein above-described base cloth layer can adopt the elastic force base cloth to make, and has good Mechanical Contraction.
Water-based PU artificial leather with third dimension decorative pattern provided by the invention, wherein said modified polyurethane are organic silicon modified polyurethane, acrylic acid modified polyurethane, epoxy modified polyurethane or watersoluble modified polyurethane.
Water-based PU artificial leather with third dimension decorative pattern provided by the invention, wherein said water-based PU resin is organic mixture of phenolic aldehyde PU resin, PU type polyurethane or PU body and polyurethane and wax solution, these PU resins can be water-based high temperature PU resins, also can adopt water-based low temperature PU resin, the PU layer has good covering effect, and is soft, has preferably high temperature resistance behind the PU, resin is volumetric expansion at high temperature, forms the velvet-like coating of one deck, is widely used in the moccasin leather.The PU layer that the PU resin forms, the foam hole is even, fine and smooth, has good heat resistance, and low temperature contractibility is little, and is fire-retardant, insulation, safety, environmental protection, the advantage such as energy-conservation.
After water-based PU artificial leather with third dimension decorative pattern provided by the invention, water-based PU resin bed are processed through 190 ℃ of high temperature PU of back segment, have strong concavo-convex third dimension, the combination that PU layer, shrinkage layer and embossing are processed has more third dimension, and effect is unique;
Water-based PU artificial leather with third dimension decorative pattern provided by the invention, wherein be coated in the modified polyurethane resin on the water-based PU resin bed, because the two polarity difference, be combined with, modified polyurethane can shrink different decorative patterns according to different release liners lines respectively, can produce good contractive effect, decorative pattern is unique, has strong visual sense of beauty.Wherein high solid bright resin is that a kind of high solids content PU artificial leather back segment process resin not only has the highlighted characteristics of high glaze, and be used in conjunction with the crystal-feel resin, mutually collaborative, have the advantages such as smooth, scratch resistance and velvet are strong after the synthetic leather that obtains is processed, and have visual effect and the feel of corium.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, further illustrate the present invention, should understand these embodiment only is used for explanation the present invention and is not used in and limits the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
As shown in Figure 1, a kind of water-based PU artificial leather with third dimension decorative pattern, it comprises base cloth layer 1, be coated in polyurethane PU layer 2 on the described base cloth layer 1, be coated in aqueous polyurethane tack coat 3 on the polyurethane PU layer 2, be coated in water-based PU resin bed 4 on the aqueous polyurethane tack coat 3, be coated in organic silicon modified polyurethane 5 on the water-based PU resin bed 4, be coated in the crystal-feel resin 6 on the organic silicon modified polyurethane 5 and be coated in solid bright resin 7 of height on the crystal-feel resin 6.
After artificial leather of the present invention, water-based PU resin bed are processed through 190 ℃ of high temperature PU of back segment, have strong concavo-convex crystal stereo sense, the combination that PU layer, shrinkage layer and embossing are processed has more third dimension, and effect is unique.Wherein high solid bright resin is that a kind of high solids content PU artificial leather back segment process resin not only has the highlighted characteristics of high glaze, and be used in conjunction with the crystal-feel resin, mutually collaborative, have the advantages such as smooth, scratch resistance and velvet are strong after the synthetic leather that obtains is processed, and have visual effect and the feel of corium.
