Abstract
The invention discloses crystal-like synthetic leather having a contraction pattern. The synthetic leather comprises a base cloth layer (1), a modified polyurethane foaming layer (2) coated on the base cloth layer (1), a polyurethane adhesive layer (3) coated on the modified polyurethane foaming layer (2), an aqueous polyurethane resin layer (4) coated on the polyurethane adhesive layer (3), an acrylic resin layer (5) coated on the aqueous polyurethane resin layer (4) and a crystal-like resin (6) coated on the acrylic resin layer (5). Contracted lines of the synthetic leather provided in the invention can generate different patterns according to difference of lines of release paper, producing a unique visual effect; the obtained synthetic leather has the effects of high brightness and high light, a strong sense of transparency and crystal and the advantages of smoothness, a strong leather feel and the like.
Description
?
Technical field
The present invention relates to a kind of PU synthetic leather, be specifically related to a kind of crystal sense synthetic leather with contracted pattern.
Background technology
At present, the synthetic leather product becomes following popular trend gradually, and synthetic 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 can also base fabric being included in, make it the existence that outward appearance can't see base fabric, it is good that the PU leather has physical property; Anti-complications, pliability is good, tensile strength is big, have gas permeability, so the PU leather is widely used in the lining of footwear or the position that case and bag bear weight.Synthetic leather mainly is to be made up of urethane resin layer and base cloth layer; The lines of synthetic leather depends on the lines of centrifugal paper; The synthetic leather third dimension is poor; In order to make synthetic leather can satisfy the demand of people to break and pattern, often to carry out the embossing treatment process to synthetic leather, make the leather surface of synthetic leather have concavo-convex three-dimensional pattern.In the prior art, synthetic leather is carried out the embossing processing have a lot of technical difficulties, the pattern poor visual effect that obtains is handled in embossing; And embossed technology needs equipment many, and cost is higher, and it is shorter to handle the pattern retention time that obtains through stamp simultaneously; Fugitive color has satisfied not people to high-level requirement.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is the deficiency that overcomes prior art, a kind of tangible contracted pattern that has is provided, the synthetic leather with strong quartzy visual effect.
Technical scheme: for solving above technical problem, the present invention takes following technical scheme:
A kind of crystal sense synthetic leather with contracted pattern; It comprises base cloth layer, be coated in modified polyurethane foaming layer on the said base cloth layer, be coated in polyurethane bonding layer in the modified polyurethane foaming layer, be coated in the waterborne polyurethane resin layer on the polyurethane bonding layer; Be coated in the acrylate resin layer on the waterborne polyurethane resin layer, and be coated in the crystal sense resin on the acrylate resin layer.
Synthetic leather with contracted pattern provided by the invention, described waterborne polyurethane resin layer are the resin bed of the compact texture processed of aromatic urethane emulsion, aromatic urethane dispersion liquid or the aromatic urethane aqueous solution.
Wherein waterborne polyurethane resin layer and acrylate resin layer because the two polarity is different, are used in combination, and can produce the contracted pattern effect, and the lines of its contraction can produce different decorative patterns according to the difference of release liners lines, and visual effect is unique;
Wherein be coated in the crystal sense resin on the acrylate resin layer; Be to dry the type polyurethane resin through last part technology roller coat one deck on acrylate resin layer; Have the effect of high bright Gao Guang, and have strong penetrating sense and quartzy sense, can fully represent the whole structure that shrinks the back decorative pattern.
Crystal sense synthetic leather with contracted pattern of the present invention, described modified polyurethane resin foaming layer are the resin bed of the compact texture processed of organic silicon modified polyurethane resin, acrylic acid modified polyurethane resin or epoxy modified polyurethane resin.
Beneficial effect: the crystal sense synthetic leather with contracted pattern provided by the invention is compared with prior art has following advantage:
1, the crystal sense synthetic leather with contracted pattern provided by the invention; Wherein be coated in waterborne polyurethane resin layer and acrylate resin layer on the polyurethane bonding layer; Because the two polarity is different, is used in combination, and can produce the contracted pattern effect; The lines of its contraction can produce different decorative patterns according to the difference of release liners lines, and visual effect is unique; And on acrylate resin layer, apply the quartzy sense of one deck resin again, the synthetic leather that obtains has the effect of high bright Gao Guang, and has strong penetrating sense and quartzy sense.
2, the crystal sense synthetic leather with contracted pattern provided by the invention, bonding is firmly between each layer of synthetic leather, coating has advantages such as anti-solvent, heat-proof aging; The synthetic leather finished product has good hand feeling, and the contracted pattern third dimension is strong, and quality is fine and smooth, advantages such as good permeability.
Description of drawings
Fig. 1 is the structural representation with crystal sense synthetic leather of contracted pattern of the present invention.
The specific embodiment
Below in conjunction with specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
As shown in Figure 1; A kind of crystal sense synthetic leather with contracted pattern; It comprises base cloth layer (1), be coated in modified polyurethane foaming layer (2) on the said base cloth layer (1), be coated in polyurethane bonding layer (3) in the modified polyurethane foaming layer (2), be coated in the waterborne polyurethane resin layer (4) on the polyurethane bonding layer (3); Be coated in the acrylate resin layer (5) on the waterborne polyurethane resin layer (4), and be coated in the crystal sense resin (6) on the acrylate resin layer (5).
Above-described crystal sense synthetic leather with contracted pattern, wherein waterborne polyurethane resin layer (4) is the resin bed of the compact texture processed of aromatic urethane emulsion, aromatic urethane dispersion liquid or the aromatic urethane aqueous solution.
Above-described crystal sense synthetic leather with contracted pattern, wherein modified polyurethane resin foaming layer (2) are the resin bed of the compact texture processed of organic silicon modified polyurethane resin, acrylic acid modified polyurethane resin or epoxy modified polyurethane resin.
Above synthetic leather wherein is coated in the acrylate resin layer (5) on the waterborne polyurethane resin layer (4), because the two polarity is different; Be used in combination; Can produce the contracted pattern effect, the lines of its contraction can produce different decorative patterns according to the difference of release liners lines, and visual effect is unique;
Be coated in the crystal sense resin (6) on the acrylate resin layer (5), the synthetic leather that obtains has the effect of high bright Gao Guang, and has strong penetrating sense and quartzy sense, and has smooth and advantages such as kishke feel is strong.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
