Abstract

The utility model discloses embossed two-tone leather which comprises a base cloth layer, a PVC foam layer applied on the base cloth layer, a polyurethane resin bonding layer applied on the PVC foam layer, and a crazy-horse polyurethane resin allochroic layer applied on the polyurethane resin bonding layer; and the upper surface of the two-tone leather is rugged and forms a plurality of convex parts and concaves parts. Compared with the prior art, the two-tone leather of the utility model has more obvious two-tone effect, stronger three-dimensional effect, and better allochroic effect.

Description

A kind of embossed two-colour leather

Technical field

The utility model relates to a kind of PVC synthetic leather, the embossed two-colour leather that particularly a kind of two-color effect is more obvious, third dimension is strong, color changeable effect is good.

Background technology

The PVC synthetic leather generally includes base cloth layer (also claiming cloth matter base material), be coated in foam polyvinyl chloride layer on the base cloth layer, be coated in the resin surface layer of foam polyvinyl chloride laminar surface.

In the prior art; often also will carry out embossed technology to the synthetic leather that has applied the resin surface layer handles; make the synthetic leather surface; also we can say and make the surface of above-mentioned resin surface layer become uneven; the leather surface has formed a plurality of protuberances and recess; on visual effect; there are certain difference in the color of protuberance and recess and gloss; because recess place resin bed is extruded, protuberance place resin bed protuberance, thereby recess is of light color, gloss is a little bit poorer slightly; the protuberance color is dark; reflecting feel is better slightly, and two-color effect is arranged from visually, therefore claims bicolor leather again.

But the two-color effect of present PVC bicolor leather is also not obvious, third dimension is strong, color changeable effect is poor.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and the embossed two-colour leather that a kind of two-color effect is more obvious, third dimension is strong, color changeable effect is good is provided.

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

A kind of embossed two-colour leather, wherein, this bicolor leather comprises base cloth layer, be coated in foam polyvinyl chloride layer on the described base cloth layer, be coated in the polyurethane resin tack coat on the described foam polyvinyl chloride layer and be coated in crazy horse polyurethane resin photochromic layer on the polyurethane resin tack coat, described bicolor leather upper surface is uneven, has formed a plurality of protuberances and a plurality of recess.

The surface layer resin of bicolor leather of the present utility model has adopted crazy horse polyurethane resin photochromic layer, has increased the color changeable effect of bicolor leather greatly; Discover through the inventor, application of polyvinyl foaming layer on base cloth layer, and the surface layer resin adopts crazy horse polyurethane resin photochromic layer (connecting by the polyurethane resin tack coat between foam polyvinyl chloride layer and the crazy horse polyurethane resin photochromic layer), the leather surface of synthetic leather is after embossing is handled, the color distortion of protuberance and recess is remarkable, recess is of light color, especially the position color near protuberance is more shallow on the recess, two-color effect is very obvious, the leather surface third dimension is strong, particularly when jack-up or stretching leather surface, strong color changeable effect is arranged, protuberance and recess double-colored, color changeable effect is more obvious.

The preferred elastic force cloth of described base cloth layer, so leather surface is by jack-up or when stretching, double-colored, color changeable effect can be better.

Generally speaking, compared with prior art, the two-color effect of the utility model bicolor leather is more obvious, third dimension is stronger, color changeable effect is better.

The specific embodiment

The utility model is described in more detail below in conjunction with accompanying drawing and concrete embodiment.

Embodiment 1

As shown in Figure 1, a kind of embossed two-colour leather, this bicolor leather 1 comprise base cloth layer 11, be coated in foam polyvinyl chloride layer 12 on the base cloth layer 11, be coated in the polyurethane resin tack coat 13 on the foam polyvinyl chloride layer 12 and be coated in crazy horse polyurethane resin photochromic layer 14 on the polyurethane resin tack coat 13.The synthetic leather that obtains is carried out embossing handle, make leather surface uneven, formed a plurality of protuberances 15 and a plurality of recess 16.

Base cloth layer 11 can adopt elastic force cloth, so leather surface is by jack-up or when stretching, and double-colored, color changeable effect can be better.

The color distortion of protuberance and recess is remarkable during the bicolor leather normality of embodiment 1 gained, and recess is of light color, and especially the position color near protuberance is more shallow on the recess, and two-color effect very obviously, stereo concave-convex sense visually is very strong; When jack-up or stretching leather surface, can see the color changeable effect of leather surface, the color distinction of protuberance and recess is bigger, and the color changeable effect of protuberance and recess is obviously different, double-colored, color changeable effect is good.

The foregoing description only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this field can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection domain of the present utility model.

Claims
