preparation example Construction

[0028] The preparation method of the above-mentioned PVC-based color-changing artificial leather for vehicles comprises the following steps: (a) placing the surface layer coating solution on a coating machine, and drying at 150°C to 200°C to obtain the surface layer; (b) A foam layer is formed on the surface of the surface layer; (c) a base cloth is pasted on the foam layer; (d) a water-based surface treatment layer is formed on the other surface of the surface layer. Specifically, in step (b), the foam layer is obtained by coating the foam layer coating liquid on the surface of the surface layer, drying and curing at 150°C to 180°C; in step (d), the The water-based surface treatment layer is obtained by coating the water-based coating solution on the surface of the surface layer, drying and curing at 100°C to 120°C.

[0029] Preferred embodiment of the present invention will be described in detail below:

Embodiment 1

[0031] This embodiment provides a kind of PVC-based color-changing artificial leather for vehicles, which includes a surface layer, a water-based surface treatment layer formed on any surface of the surface layer, a foam layer formed on the other surface of the surface layer, and a foam layer formed outside the foam layer. The base fabric layer on the surface and the surface layer are obtained by curing the surface layer coating liquid;

[0032] The above-mentioned layers are obtained by drying the corresponding coating liquid, and the specific coating liquid configuration is as follows (the following are the mass contents):

[0033] Water-based coating liquid configuration: add polyvinyl chloride resin 78%, N-vinylimidazolium salt polymer (number average molecular weight 1000) 13%, 2,2,4-trimethyl-1,3-pentanedi 5% alcohol monoisobutyrate, 1% defoamer BYK1790, 1% carboxymethyl cellulose, 2% polymethylurea resin (data molecular weight 1000), fully stirred at room temperature fo...

Embodiment 2

[0042] This embodiment provides a kind of PVC-based discoloration artificial leather for vehicles and a preparation method thereof, which is basically the same as that in Example 1, except that the surface layer coating solution contains the following components by mass:

[0043] Silane coupling agent (vinyltrimethoxysilane, Nanjing Chengong organic silicon CG171) 1.5% (0.28% based on silicon element), temperature-sensitive toner JY031 (Shenzhen Jingyizi Technology Co., Ltd., 31 degrees from colorless to Red temperature-sensitive toner) 10%, pigment (black) 10%, then add polyvinyl chloride resin 49.0%, phthalate plasticizer 25%, calcium zinc stabilizer 2.0%, calcium carbonate inorganic filler 2.5%.

Abstract

The invention relates to PVC-based color-changing artificial leather for a vehicle. The PVC-based color-changing artificial leather comprises a surface layer, a water-based surface treatment layer formed on any surface of the face layer, a foamed layer formed on the other surface of the surface layer, and a base cloth layer formed on the outer surface of the foamed layer; and the surface layer isprepared from the raw material components in percentage by mass: 0.5-1.5% of a silane coupling agent, 5-20% of color-changing toner, 0.5-4% of a pigment, 60-75% of polyvinyl chloride resin, and 1.0-20% of an assistant, wherein silicon in the silane coupling agent accounts for 0.01-0.5% of the surface layer in mass. By adopting a specifically-matched surface layer coating liquid raw material and conducting mixing according to the specific sequence, the color-changing toner can form a microcapsule structure, the dispersion uniformity of the color-changing toner can be effectively improved, the color-changing toner is prevented from being eroded by other substances, and thus the problems of nonuniform dispersion of the color-changing toner, poor stability and the like are avoided.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and relates to an artificial leather, in particular to a PVC-based color-changing artificial leather for vehicles and a preparation method thereof. Background technique [0002] Color-changing leather will show different colors at low temperature and high temperature respectively. The color of the finished products made of color-changing leather will change with the change of contact temperature during use, and its color will change from dark to light, or from dark to light, from one color to another, full of endless changes The mysterious atmosphere, so deeply loved by consumers. The color-changing leather that appears on the market, because the color-changing material added to the artificial leather is prone to problems such as uneven dispersion and poor stability, resulting in uneven color and poor durability such as stains in the color-changing leather, which affects the quality of...
