Abstract

The utility model relates to polyurethane synthetic leather, and specifically relates to hydrolysis-resistant environment-friendly shoe leather, belonging to the technical field of synthetic leather in plastic products. The hydrolysis-resistant environment-friendly shoe leather sequentially comprises base cloth, a Bass layer, a dry method layer, a primary printing layer and a secondary printing layer from inside to outside, wherein the Bass layer and the dry method layer adopt hydrolysis-resistant polyether polyurethane slurries, and hydrolysis-resistant auxiliaries are added into the printing layers, so that the hydrolysis resistance of the leather is improved. The hydrolysis-resistant environment-friendly shoe leather is primarily and secondarily printed by adopting a waterborne coating, so that the production process is environment-friendly and non-toxic and the product is healthy and environment-friendly. After primary printing, composite surface treatment processes such as embossing treatment and the like are carried out by using a matte knurling roll. Finally, the formed leather has the characteristics of clear three-dimensional contour and strong optical haze effect in appearance, and is endowed with the characteristics of uniqueness and high grade of the leather.

Description

A kind of Environmental-protection shoes leather of hydrolysis

Technical field

The utility model relates to a kind of Synthetic Leather, is specifically related to a kind of Environmental-protection shoes leather of hydrolysis, belongs to the technical field of synthetic leather in plastic products.

Background technology

Along with the fast development of footwear leather, the top grade leather that is applicable to high-grade leather shoes, commercial footwear is comparatively rare.Existing footwear leather generally has the drawbacks such as poor, the airtight and surface effect of hydrolytic resistance is comparatively common, can not finely meet the requirement of the comfortable dress of shoes and outward appearance fashion.

Summary of the invention

The deficiency existing for prior art, the utility model provides a kind of hydrolysis and has had the Environmental-protection shoes leather of unique look effect, have good gas permeability, good hydrolytic resistance, and surface can form unique embossing effect.

The Environmental-protection shoes leather of described a kind of hydrolysis consists of base cloth, bass layer, dry method layer, one-step print layer and secondary printing layer from inside to outside successively, wherein base cloth is as end embryo, adopt the EU wet method slurry of hydrolysis to be coated with and to form bass layer by wet processing, the uniform pore of the inner formation of bass layer, formation has certain elasticity, has certain air permeability simultaneously; EU dry method slurry on bass layer surface with hydrolysis forms the relatively fine and close dry method layer of one deck structure by dry coating technique, on dry method layer surface, adopt special water-based printing technique, select water paint printing to form one deck aqueous coating, this coating color and luster is full soft, and surperficial feel is more natural, after embossed, form concavo-convex decorative pattern clearly, recycling contains the water paint that contrast colorant and carries out secondary printing, has the secondary printing layer of optical haze sense at convex surface formation one deck of one-step print lamination line.

Adopt the technical program to produce following useful effect: described bass layer adopts polyurethane wet therapy forming process, owing to adding special blowing agent and unique sizing foam process, the uniform pore of inner formation after sizing, increased elasticity, there is higher gas permeability simultaneously, greatly increased the comfortableness of leather dress; Dry method layer surface adopts water paint printing, owing to adopting water paint, after sizing, can residual harmful substance in leather, there is the better health of wearing, and production process is environmental protection more, do not have organic exhaust gas to produce, realized green manufacturing, one-step print carries out secondary printing again by embossed, formation has the Z-Correct bump mapping Z-correct of certain color contrast, and third dimension and optical haze sense are stronger, and fashion is high-grade.

Below in conjunction with accompanying drawing, the utility model is further described.

Accompanying drawing explanation

Fig. 1 is the Environmental-protection shoes leather structural representation of a kind of hydrolysis of the utility model embodiment.

In figure: 1 base cloth, 2 bass layers, 3 dry method layers, 4 one-step print layers and 5 secondary printing layers.

The specific embodiment

The utility model embodiment provides a kind of Environmental-protection shoes leather of hydrolysis, Fig. 1 is the Environmental-protection shoes leather structural representation of a kind of hydrolysis of the utility model embodiment, the Environmental-protection shoes leather of a kind of hydrolysis described in the Environmental-protection shoes leather of a kind of hydrolysis described in the present embodiment is from inside to outside successively by base cloth 1, bass layer 2, dry method layer 3, one-step print layer 4 and secondary printing layer 5 form, wherein base cloth 1 is as end embryo, adopt the EU wet method slurry of hydrolysis to be coated with and to form bass layer 2 by wet processing, owing to having added special blowing agent and unique sizing foam process in wet method slurry, after wet method sizing, the uniform pore of bass layer 2 inner formation, increased elasticity, there is higher gas permeability simultaneously, increased the comfortableness of leather dress, on bass layer 2 surface, with the EU dry method slurry of hydrolysis, by dry coating technique, form the densification and there is the dry method layer 3 of good hydrolytic resistance relatively of one deck structure, on dry method layer 3 surface, adopt special water-based printing technique, select water paint printing to form one deck aqueous coating, this coating color and luster is full soft, and surperficial feel is more natural, after embossed, form concavo-convex decorative pattern clearly, recycling contains the water paint that contrast colorant and carries out secondary printing, has the secondary printing layer 5 of optical haze sense at convex surface formation one deck of one-step print layer 4 embossing.Because one-step print and secondary printing all adopt water prescription, the printed layers color forming is softer, and production process environment-protecting asepsis, the final leather forming has clean mark, third dimension and optical haze sense is strong, fashion is high-grade and anti-hydrolytic performance is good, the feature of environment protection health.

The present embodiment is only for illustrating the use of the utility model, be not to restriction of the present utility model, those skilled in the art can also make corresponding distortion and modification in essential scope of the present utility model, and the embodiment being equal to so any belongs to category of the present utility model.
