Problems solved by technology

However, in practice, it is difficult to obtain a good rubbing effect on the basis of natural luster, firm bonding, luster and soft touch after surface treatment of synthetic leather.
[0003] The artificial leather printing material in the prior art is composed of 100 parts by weight of polyurethane treatment agent and 10-30 parts by weight of organic solvent (such as MEK). After it is printed on the surface of semi-finished leather products, the surface cannot obtain the color rubbing effect

Abstract

The invention relates to an artificial leather printing material, which is prepared from the following raw materials in parts by weight: 95-105 parts of PU (Poly Urethane) brushing resin, 10-20 parts of organic solvent and 5-10 parts of PU color paste. The invention also relates to artificial leather and a preparation method thereof. The artificial leather obtained after the artificial leather printing material is printed has a brush-off effect, and has the advantages of good stability and high colour fastness.

Description

technical field [0001] The invention relates to artificial leather technology, in particular to an artificial leather printing material, artificial leather and a preparation method thereof. Background technique [0002] In the prior art, in order to obtain the desired color, softness and brightness of synthetic leather products, it is generally necessary to carry out surface treatment on synthetic leather during the manufacturing process. The synthetic leather surface treatment agent can be used for surface finishing according to the product category, which can improve the brightness, color and feel of the synthetic leather. However, in practice, it is difficult to obtain a good color rubbing effect on the basis of natural luster, firm bonding, luster and soft touch of synthetic leather after surface treatment. [0003] The artificial leather printing material in the prior art consists of 100 parts by weight of polyurethane treatment agent and 10-30 parts by weight of organ...
