Embodiment Construction

[0030] Please refer to Figure 1 to Figure 5 As shown, it shows the specific structure of the embodiment of the present invention.

[0031] A PU double-layer crystal mirror leather, comprising a base fabric 10, a wet-process PU layer 20, a dry-process PU texture layer 30, a printing layer 40, an adhesive layer 50, and a transparent polyurethane elastomer 60. Use transparent polyurethane elastomer resin to increase the crystal transparency and softness of the product, and inject additives on the surface of the dry layer texture and then paste transparent polyurethane elastomer 60 to expel air bubbles from the PU Leather surface, reduce original air bubbles and improve permeability and efficiency.

[0032] The laminating method of described PU double-layer crystal mirror leather comprises the following steps:

[0033] Step 1: Coating a wet-process PU layer 20 above the base cloth 10;

[0034] Step 2: coating the dry-process PU texture layer 30 on the wet-process PU layer 20; ...

Abstract

The invention discloses PU (Poly Urethane) double-layer crystal mirror leather and a laminating method thereof. The laminating method comprises the following steps: step 1, coating a wet-process PU layer above base cloth; step 2, coating the wet-process PU layer with the dry-process PU grain layer; 3, overprinting a printing layer on the dry-process PU grain layer to obtain a first-stage semi-finished product; 4, coating the mirror release paper with transparent polyurethane elastomer slurry, drying to form a transparent polyurethane elastomer, coating the transparent polyurethane elastomer with polyurethane slurry, and drying the polyurethane slurry to be half-dry to serve as an adhesion layer to obtain a second-stage semi-finished product; 5, injecting an auxiliary agent on the printing layer of the first-stage semi-finished product, and then attaching the adhesion layer of the second-stage semi-finished product; and 6, the bubble row is squeezed out of the outer surface obtained after the first-stage semi-finished product and the second-stage semi-finished product are compounded, then the PU double-layer crystal mirror surface leather is manufactured through attaching, drying and cooling in sequence, and the PU double-layer crystal mirror surface leather has the advantages of being high in crystal feeling, good in permeability and the like mainly through the design of all the steps.

Description

technical field [0001] The invention relates to the technology in the field of synthetic leather production, in particular to a PU double-layer crystal mirror leather and a bonding method thereof. Background technique [0002] PU synthetic leather, also known as polyurethane synthetic leather, is generally composed of base fabric and polyurethane coating layer. It is widely used in luggage, clothing, shoes, vehicles and furniture. Its wide application range, large quantity and variety are traditional. Natural leather cannot meet the requirements, but the existing PU double-layer crystal mirror products cannot be widely produced and used, mainly because polyurethane itself is prone to produce bubbles and blank spots, resulting in poor transparency, low efficiency, and high cost. There are fewer textures to choose, and it is generally only suitable for fine textures, and slightly deeper textures are prone to abnormalities. [0003] Therefore, it is necessary to study a new te...
