Embodiment 1

[0031] A gradual perforated leather provided in this embodiment and a preparation method thereof: firstly, the base 7 is processed. The process includes S1 release paper preparation, S2 surface layer 5 coating, S3 foam layer 4 coating, S4 base fabric layer 3 lamination, S5 release paper peeling. Wherein the surface layer 5 and the foam layer 4 are made of polyurethane. The base fabric layer 3 has a thickness ranging from 700 μm to 1100 μm and a weight range of 200 g / m 2 ~400g / m 2 Circular knitted fabrics, warp knitted fabrics, woven fabrics, or non-woven fabrics. The release paper is textured or non-textured, and the surface is PP or silicone oil-coated leather transfer paper. The surface layer 5 includes polyurethane, pigments and dissolution medium; the mass percentages of the material components of the surface layer 5 are: 50.5% to 69.1% polyurethane, 9.9% to 16.5% pigment, and 26% to 28% dissolution medium. The dissolution medium is MEK and DMF. The foam layer 4 inclu...

Embodiment 2

[0041] The difference between the gradient pattern perforated leather provided in this embodiment and its preparation method and that in Embodiment 1 is:

[0042] S8 heat lamination process, use heat lamination machine to carry out the processing of hot melt adhesive layer 2 and base fabric layer 1 on the base blank 6 obtained in step S7. The processing of the hot-melt adhesive layer 2 includes the setting of the temperature of the hot-melt adhesive machine and the temperature of the rollers. The hot-melt adhesive is solid and needs to be melted on a special hot-melt adhesive machine. The temperature of the hot-melt adhesive machine is set to 80 degrees, and the temperature of the roller is set to 80 degrees (the hot-melt adhesive machine is for melting the hot-melt adhesive, and the working roller is for heat preservation. ), the viscosity of the hot melt adhesive is 8500cps. Spread the hot-melt adhesive evenly on the roller, and when the roller rotates, the hot-melt adhesiv...

Embodiment 3

[0044] The difference between the gradient pattern perforated leather provided in this embodiment and its preparation method and that in Embodiment 1 is:

[0045] S8 heat lamination process, use heat lamination machine to carry out the processing of hot melt adhesive layer 2 and base fabric layer 1 on the base blank 6 obtained in step S7. The processing of the hot-melt adhesive layer 2 includes the setting of the temperature of the hot-melt adhesive machine and the temperature of the rollers. The hot-melt adhesive is solid and needs to be melted on a special hot-melt adhesive machine. The temperature of the hot-melt adhesive machine is set to 85 degrees, and the temperature of the roller is set to 85 degrees (the hot-melt adhesive machine is for melting the hot-melt adhesive, and the working roller is for heat preservation. ), the viscosity of the hot melt adhesive is 10000cps. Spread the hot-melt adhesive evenly on the roller, and when the roller rotates, the hot-melt adhesi...

Abstract

The invention provides perforated leather with a ramp texture. The perforated leather comprises a bottom cloth layer, a hot melt adhesive layer connected with the bottom cloth layer, a base cloth layer connected with the hot melt adhesive layer, a foaming layer connected with the base cloth layer, a surface layer connected with the foaming layer and a surface treatment layer connected with the surface layer, wherein the base cloth layer and the hot melt adhesive layer are prepared by a hot laminating method; the base cloth layer, the foaming layer and the surface layer are prepared by a coating method; the surface treatment layer, the surface layer, the foaming layer and the base cloth layer are sequentially punched to obtain a bottom blank; and the bottom blank and the hot melt adhesive layer form an integrated structure through the hot laminating method; The perforated leather is prepared by the hot laminating method and the coating method and is obtained after punching; and by designing the pattern of gradiently-changing back pasting bottom cloth and the polyurethane bottom blank and combining an original single color and an original single pattern, a multi-layer pattern and stereoscopic impression are realized.

Description

technical field [0001] The invention relates to the technical field of polyurethane material modification and preparation, in particular to a perforated leather with gradient pattern and a preparation method of the perforated leather with gradient pattern. Background technique [0002] The color and decoration design of automobile interior needs to fully consider the needs of human nature. The quality of the interior is mainly reflected in the color, texture, luster, material, and appearance decoration of the interior parts, so as to create a safe, comfortable and pleasant driving environment for customers. Take advantage of the space, and then create a high-quality feeling, which has become an important means to win customers. In recent years, with the development of social economy and the transformation of market supply and demand, consumers' consumption concept of passenger cars has also changed. In addition to the demand for car functions, the choice of cars has more per...
