The utility model provides a waterborne synthetic leather, environmental protection, low toxicity, have unique dry and slippery feel, waterproof performance is good.
Description
Technical field
The utility model relates to a kind of PU synthetic leather, is specifically related to a kind of water-based synthetic leather with dry sliding sense.
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; Cost is higher, and it is shorter to handle the pattern retention time that obtains through stamp simultaneously, fugitive color; And the synthetic leather kishke feel is not strong in the prior art, has satisfied not people to high-level requirement.
Summary of the invention
Goal of the invention: the utility model technical problem to be solved is the deficiency that overcomes prior art, and a kind of contracted pattern that has is provided, the water-based synthetic leather of the environmental protection that dry sliding sense is strong.
Technical scheme: for solving above technical problem, the utility model is taked following technical scheme:
A kind of water-based synthetic leather with dry sliding sense; Comprise base cloth layer, be coated in polyurethane foam layer on the base cloth layer, be coated in aqueous polyurethane tack coat on the polyurethane foam layer, be coated in aqueous foaming resin bed on the aqueous polyurethane tack coat, be coated in waterborne polyurethane resin layer on the aqueous foaming resin bed, be coated in the modified polyurethane resin layer on the waterborne polyurethane resin layer, and be coated in the water-based dry sliding sense processing layer on the modified polyurethane resin layer.
Wherein above-described base cloth layer can adopt the elastic force base cloth to process, and has good mechanical contraction property.
As preferred version, the synthetic leather with contracted pattern that the utility model provides, described waterborne polyurethane resin layer are the resin bed that aromatic urethane emulsion, aromatic urethane dispersion liquid or the aromatic urethane aqueous solution are processed.
As preferred version, the resin bed of the compact texture that the synthetic leather with contracted pattern that the utility model provides, described waterborne polyurethane resin layer are processed by aliphatic polyurethane emulsion, aliphatic polyurethane dispersion liquid or the aliphatic polyurethane aqueous solution.
As preferred version; The synthetic leather with contracted pattern that the utility model provides, described modified polyurethane resin layer are the resin bed of the compact texture processed of organic silicon modified polyurethane, acrylic acid modified polyurethane, epoxy modified polyurethane or watersoluble modified polyurethane.
Wherein be coated in the modified polyurethane resin layer on the waterborne polyurethane resin layer, 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;
After applying water-based dry sliding sense processing layer on the modified polyurethane resin layer, it is unique especially that leather is done sliding feel, and aspect resultant effects such as its feel of synthetic leather, waterproof, bonding are good.
The synthetic leather with contracted pattern that the utility model provides, described dry sliding sense processing layer is processed by following raw materials according by it: waterborne polyurethane resin 30 ~ 40%, water 50 ~ 60%, silicon modified organic polymer 1 ~ 5%, modified amino silicon oil 5 ~ 8%, aqueous polyurethane thickener 1 ~ 2%.
Beneficial effect: the water-based synthetic leather with dry sliding sense that the utility model provides is compared with prior art has following advantage:
1, it is unique especially that the water-based synthetic leather with dry sliding sense that the utility model provides, leather surface are done sliding feel, and aspect resultant effects such as its feel of synthetic leather, waterproof, bonding are good.Be coated in the modified polyurethane resin layer on the waterborne polyurethane resin layer, 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;
2, the water-based synthetic leather with dry sliding sense that the utility model provides, aqueous polyurethane tack coat and aqueous foaming resin bed are processed leather and are had environmental protection, advantage such as fire-retardant;
3, the water-based synthetic leather that the utility model provides with dry sliding sense, bonding is firmly between each layer of synthetic leather, 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 described structural representation with water-based synthetic leather cross section of dry sliding sense of the utility model.
The specific embodiment
Below in conjunction with specific embodiment; Further illustrate the utility model; Should understand these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, 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 utility model.
As shown in Figure 1; A kind of water-based synthetic leather with dry sliding sense; Comprise base cloth layer (1), be coated in polyurethane foam layer (2) on the base cloth layer (1), be coated in aqueous polyurethane tack coat (3) on the polyurethane foam layer (2), be coated in aqueous foaming resin bed (4) on the aqueous polyurethane tack coat (3), be coated in waterborne polyurethane resin layer (5) on the aqueous foaming resin bed (4), be coated in the modified polyurethane resin layer (6) on the waterborne polyurethane resin layer (5), and be coated in the water-based dry sliding sense processing layer (7) on the modified polyurethane resin layer (6).
