Abstract
The utility model discloses a stress color-changing synthetic leather which comprises a bunchy superfine fiber base cloth layer, a dry color-changing polyurethane coating layer, a waterborne polyurethane resin layer and a modified polyurethane resin layer, wherein the dry color-changing polyurethane coating layer is coated on the bunchy superfine fiber base cloth layer, the waterborne polyurethane resin layer is coated on the dry color-changing polyurethane coating layer, and the modified polyurethane resin layer is coated on the waterborne polyurethane resin layer. The stress color-changing synthetic leather disclosed by the utility model has a uniform color-changing effect under the action of external stresses such as drawing, bending and folding.
Description
Technical field
The utility model relates to the artificial leather technical field, is specifically related to a kind of stress variable color synthetic leather.
Background technology
Synthetic leather is the plastic products that the The Nomenclature Composition and Structure of Complexes of simulation natural leather is made, and is widely used in to make footwear, boots, case and bag, clothes etc.The Synthetic Leather that tradition is used for shoemaking, case and bag mainly is black or brown.And single color can't satisfy the appreciation taste that people improve day by day, and developing the synthetic leather product that some colors are various, artistic expression is strong has been development in future trend.
Application number is that 201120435573.9 Chinese utility model patent discloses a kind of composite leather with voluptuousness and colour change function, has comprised leather blank layer, voluptuousness resin bed, coat of colo(u)r, allochroic paint layer, minute surface resin bed.This composite leather has color changeable effect external stresses such as being stretched, crooked, folding as the time spent.But because this composite leather will be taken into account voluptuousness and two kinds of functions of variable color, the allochroic paint layer is located at organosilicon and the oil modification emulsion acrylic resin is that color changeable effect is inhomogeneous on the voluptuousness resin bed.
The utility model content
The purpose of this utility model is to overcome the defective of above-mentioned prior art, and a kind of stress variable color synthetic leather is provided, and it has uniform color changeable effect external stresses such as being stretched, crooked, folding as the time spent.
For achieving the above object, the utility model adopts following technical scheme:
A kind of stress variable color synthetic leather, it comprises the bundle superfine fibre base cloth layer, be coated in dry method color-changing polyurethane dope layer on the bundle superfine fibre base cloth layer, be coated in waterborne polyurethane resin layer on the dry method color-changing polyurethane dope layer, be coated in the modified polyurethane resin layer on the waterborne polyurethane resin layer.
The thickness of described dry method color-changing polyurethane dope layer is 100 microns～500 microns.
Described modified polyurethane resin layer is the organic silicon modified polyurethane resin bed.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts the bundle superfine fibre base cloth layer as the base material of synthetic leather, applied dry method color-changing polyurethane dope layer in the above, and between dry method color-changing polyurethane dope layer and the modified polyurethane resin layer as the synthetic leather superficial layer, be provided with the waterborne polyurethane resin layer, make that the stress color changeable effect of synthetic leather is good, concrete principle is: because base cloth is the bundle superfine fibre base cloth layer, its tensile deformation is even, thereby making the dry method color-changing polyurethane dope layer that applies in the above when stretching, be subjected to uniform tractive force, variable color is even; Moreover color-changing polyurethane coating is to add the variable color powder in polyurethane resin, and heat resistance is poor, adopts the dried method of dying can overcome its defective; At last, dry method color-changing polyurethane dope layer does not directly contact with superficial layer, and the tensile force that is subjected to when being stretched can evenly further strengthen the uniform effect of stress variable color.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Please refer to Fig. 1, stress variable color synthetic leather of the present utility model comprises bundle superfine fibre base cloth layer 1, dry method color-changing polyurethane dope layer 2, waterborne polyurethane resin layer 3, modified polyurethane resin layer 4 from bottom to top successively.
Particularly, the thickness of described dry method color-changing polyurethane dope layer 2 is 100 microns～500 microns.Described modified polyurethane resin layer 4 is the organic silicon modified polyurethane resin bed.
Above-mentioned embodiment only is preferred embodiment of the present utility model; can not limit the scope of the utility model protection with this, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
Claims (3)
1. stress variable color synthetic leather is characterized in that: comprise the bundle superfine fibre base cloth layer, be coated in dry method color-changing polyurethane dope layer on the bundle superfine fibre base cloth layer, be coated in waterborne polyurethane resin layer on the dry method color-changing polyurethane dope layer, be coated in the modified polyurethane resin layer on the waterborne polyurethane resin layer.
2. stress variable color synthetic leather as claimed in claim 1, it is characterized in that: the thickness of described dry method color-changing polyurethane dope layer is 100 microns～500 microns.
