Title:
LIGHT-TRANSMITTING ARTIFICIAL LEATHER, PREPARATION METHOD THEREFOR, AND AUTOMOBILE INTERIOR
Document Type and Number:
WIPO Patent Application WO/2021/195869
Kind Code:
A1
Abstract:
Disclosed are a light-transmitting artificial leather, a preparation method therefor, and an automobile interior. The preparation method therefor comprises the following steps: mixing a primary raw material containing toner having a particle size of 0.5 to 10 μm, polymer powder and a plasticizer, and stirring, grinding, filtering and defoaming same to obtain a light-transmitting pigment raw material; mixing the light-transmitting pigment raw material with a secondary raw material containing polymer powder, a plasticizer, a stabilizer and an inorganic additive, and stirring, filtering and defoaming same to obtain a light-transmitting skin layer raw material; and using a base fabric, a glue raw material, a support layer raw material and the light-transmitting skin layer raw material for preparing, so as to obtain an artificial leather semi-finished product formed by the light-transmitting skin layer, a support layer, a glue layer and the base fabric arranged in sequence; and coating a surface treatment agent on the surface of the light-transmitting skin layer, so as to obtain a light-transmitting artificial leather. The toner in the light-transmitting skin layer raw material uses toner having a nano-scale particle diameter, so that the degree to which the toner obstructs light is reduced, and the prepared artificial leather is guaranteed to have a certain light transmittance.
