Abstract

The invention discloses color-changing velvet-feel synthetic leather with high brightness. The color-changing velvet-feel synthetic leather comprises a base cloth layer (1), a polyurethane foaming layer (2) coated on the base cloth layer (1), a polyurethane bonding layer (3) coated on the polyurethane foaming layer (2), a water-borne polyurethane resin layer (4) coated on the polyurethane bonding layer (3), a water-borne PU (polyurethane) color-changing resin layer (5) coated on the water-borne polyurethane resin layer (4), a high-strength polished resin layer (6) coated on the water-borne PU color-changing resin layer (5) and a water-borne PU velvet-feel resin layer (7) coated on the high-strength polished resin layer (6). In the synthetic leather provided by the invention, the water-borne PU velvet-feel resin layer has a unique velvet-feel effect; the water-borne PU color-changing resin layer has a full hand feel and a unique color-changing effect; and the synthetic leather has a highlight effect and a strong real leather feel.

Description

A kind of variable color velvet synthetic leather with Gao Liang

Technical field

The present invention relates to a kind of PU synthetic leather, be specifically related to a kind of Gao Liang of having, the synthetic leather that the band color changeable effect has velvet.

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: technical problem to be solved by this invention is the deficiency that overcomes prior art, provides a kind of and has the bright high light visual effect of strong height, and color changeable effect and the synthetic leather that has velvet are arranged.

Technical scheme: for solving above technical problem, the present invention takes following technical scheme:

A kind of variable color velvet synthetic leather with Gao Liang, it comprises base cloth layer, be coated in polyurethane foam layer on the said base cloth layer, be coated in polyurethane bonding layer on the polyurethane foam layer, be coated in waterborne polyurethane resin layer on the polyurethane bonding layer, be coated in water-based PU color-change resin layer on the waterborne polyurethane resin layer, be coated in solid bright the resin bed of height on the water-based PU color-change resin layer and be coated in the water-based PU velvet resin on high solid bright the resin bed.

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 provided by the invention, 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 provided by the invention, described waterborne polyurethane resin layer are processed by aliphatic polyurethane emulsion, aliphatic polyurethane dispersion liquid or the aliphatic polyurethane aqueous solution.

Wherein water-based PU color-change resin layer and high solid bright resin bed 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 high solid bright resin is the characteristics that a kind of high solids content PU synthetic leather rear section process resin not only has high glaze Gao Liang; And be used with acrylic acid modified resin bed; Collaborative each other; Have advantages such as smooth, scratch resistance after the synthetic leather that obtains is handled, and have the visual effect and the feel of corium.

Synthetic leather with contracted pattern provided by the invention, described water-based PU velvet resin layer be by waterborne polyurethane resin 40～50%, water 40～55%; Low temperature sheep crust powder 2-5%, silica velvet powder 2-4%, organic silicone oil slipping agent 1～3%; Flatting silica 1～4% is processed, and water-based PU velvet resin layer has unique velvet effect, and strong kishke feel is arranged; Quality is fine and smooth, advantages such as good permeability

Synthetic leather with contracted pattern provided by the invention, described water-based PU color-change resin layer be by waterborne polyurethane resin 35～45%, water 30～40%; Silica variable color powder 6～9%; Flatting silica 2-6%, amido silicon oil slipping agent 5～8%, emulsifying wax 5-8% processes.Water-based PU color-change resin layer has good hand feeling, and unique color changeable effect has strong kishke feel.

Beneficial effect: the variable color velvet synthetic leather of the Gao Liang of having provided by the invention is compared with prior art has following advantage:

1, the variable color velvet synthetic leather with Gao Liang provided by the invention, water-based PU velvet resin layer have unique velvet effect, and water-based PU color-change resin layer has good hand feeling, and unique color changeable effect has strong kishke feel.And water-based PU color-change resin layer and high solid bright resin bed 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.

2, the variable color velvet synthetic leather with Gao Liang provided by the invention applies solid bright the resin bed of a floor height, and the synthetic leather that obtains has the effect of high bright Gao Guang, and has strong penetrating sense and smooth feeling.

3, the variable color velvet synthetic leather with Gao Liang provided by the invention, 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.
