Abstract

The utility model discloses synthetic leather with cracking patterns. The 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 waterborne polyurethane resin layer (4) coated on the polyurethane bonding layer (3), and a polyurethane cracking resin layer (5) coated on the waterborne polyurethane resin layer (4). In the synthetic leather provided by the utility model, the polyurethane cracking resin layer (5) coated on the waterborne polyurethane resin layer (4) has a special bright surface cracking effect; the polyurethane cracking resin layer (5) and the waterborne polyurethane resin layer (4) are combined to play a collaborative promote role; different patterns are formed by shrinking according to different release paper lines; and the synthetic leather has a strong cracking contraction visual aesthetic feeling.

Description

A kind of synthetic leather be full of cracks decorative pattern

Technical field

The utility model relates to a kind of PU synthetic leather, is specifically related to a kind of synthetic leather be full of cracks decorative pattern.

Background technology

Along with the development of industrial technology, 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.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: the utility model technical problem to be solved is the deficiency that overcomes prior art, and a kind of have tangible be full of cracks decorative pattern, the synthetic leather with strong visual effect are provided.

Technical scheme: for solving above technical problem, the utility model is taked following technical scheme:

A kind of synthetic leather be full of cracks decorative pattern, 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 the waterborne polyurethane resin layer on the polyurethane bonding layer and be coated in the polyurethane cracking resin for synthesizing layer on the waterborne polyurethane resin layer.

Wherein above-described base cloth layer can adopt the elastic force base cloth to process, and has good mechanical contraction property.

The utility model provides has a synthetic leather of be full of cracks decorative pattern, and wherein said waterborne polyurethane resin layer is the resin bed of the compact texture processed of aliphatic polyurethane emulsion, aliphatic polyurethane dispersion liquid or the aliphatic polyurethane aqueous solution.

Wherein be coated in the polyurethane cracking resin for synthesizing on the waterborne polyurethane resin; Have bright special crazing effect,, be used in combination because the two polarity is different; The polyurethane cracking resin for synthesizing can shrink different decorative patterns according to different release liners lines respectively with waterborne polyurethane resin; Can produce good contractive effect, decorative pattern is unique, has strong visual sense of beauty.

Beneficial effect: the synthetic leather be full of cracks decorative pattern that the utility model provides is compared with prior art has following advantage:

1, the synthetic leather that the utility model provides be full of cracks decorative pattern; The polyurethane cracking resin for synthesizing that wherein is coated on the waterborne polyurethane resin has bright special crazing effect, and the two combines, and plays the collaborative effect that promotes; Can produce good contractive effect; Decorative pattern is unique, can shrink different decorative patterns according to different release liners lines, has strong visual sense of beauty.

2, the utility model provides has the synthetic leather of be full of cracks decorative pattern, shows through experimental study, and firm, the coating of bonding has advantages such as anti-solvent, hydrolysis, heat-proof aging between each layer of synthetic leather; The synthetic leather finished product has good hand feeling, strong kishke feel is arranged, advantages such as good permeability.

Description of drawings

Fig. 1 has the structural representation of the synthetic leather of be full of cracks decorative pattern for the utility model is described.

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 synthetic leather be full of cracks decorative pattern, it comprises base cloth layer (1), be coated in polyurethane foam layer (2) on the said base cloth layer (1), be coated in polyurethane bonding layer (3) on the polyurethane foam layer (2), be coated in the waterborne polyurethane resin layer (4) on the polyurethane bonding layer (3) and be coated in the polyurethane cracking resin for synthesizing layer (5) on the waterborne polyurethane resin layer (4).

The resin bed of the compact texture that described waterborne polyurethane resin layer (4) is processed by aliphatic polyurethane emulsion, aliphatic polyurethane dispersion liquid or the aliphatic polyurethane aqueous solution.

Above synthetic leather; Wherein be coated in the polyurethane cracking resin for synthesizing layer (5) on the waterborne polyurethane resin layer (4), have bright special crazing effect, the two is used in combination; Can produce good contractive effect; Have unique decorative pattern, and cracking resin for synthesizing layer (5) can shrink different decorative patterns according to different release liners lines with waterborne polyurethane resin layer (4), have strong visual sense of beauty.

A kind of synthetic leather be full of cracks decorative pattern that the utility model provides, its feel and high comprehensive performance have bright special crazing effect and can produce good contractive effect, have unique decorative pattern, have strong visual sense of beauty.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
