Embodiment 1

[0031] The artificial leather with high color fastness of the present embodiment is prepared from the following raw materials in parts by weight: 95 parts of polyurethane surface treatment agent, 5 parts of organic solvent and 3 parts of colorant. 40% of the total content. The organic solvent is methyl ethyl ketone. Described polyurethane surface treatment agent is 7007 type polyurethane surface treatment agent.

[0032] The preparation method of the above-mentioned artificial leather with high color fastness in this embodiment is to mix the above-mentioned raw materials by weight and coat them on the release paper, carry out plasticization molding, and then peel off from the release paper to obtain the artificial leather with high color fastness .

Embodiment 2

[0034] Only "prepared from the following raw materials by weight: 105 parts of polyurethane surface treatment agent, 10 parts of organic solvent and 6 parts of colorant, the solid content of said polyurethane surface treatment agent accounts for more than 60% of the total content of polyurethane surface treatment agent. Described organic solvent is butyl ester. Described polyurethane surface treatment agent is 7040 type polyurethane surface treatment agent " and embodiment one is different, and other is all identical with embodiment one.

Abstract

The invention relates to high-color-fastness artificial leather. The high-color-fastness artificial leather is prepared from raw materials in parts by weight as follows: 95-105 parts of a polyurethane surface treating agent, 5-10 parts of an organic solvent and 3-6 parts of dye, and the solid content of the polyurethane surface treating agent is 40% of the total content of the polyurethane surface treating agent or above. The invention further relates to a preparation method of the high-color-fastness artificial leather. The high-color-fastness artificial leather has high color fastness and is low in material consumption and high in vehicle speed.

Description

technical field [0001] The invention relates to artificial leather technology, in particular to an artificial leather with high color fastness and a preparation method thereof. Background technique [0002] The existing artificial leather formula comprises 100 parts of polyurethane surface treatment agent, 5-10 parts of methyl ethyl ketone (MEK) and 5-9 parts of color chips. The preparation method is as follows: mixing and stirring polyvinyl chloride resin and plasticizer, evenly coating and scraping on the release paper, undergoing high-temperature plasticization and molding, peeling off the release paper to form leather, and the semi-finished leather products produced by the host machine are processed or processed. Print it out to form a finished product. The treatment agent is covered on the surface of the treatment wheel, and the front of the leather is in contact with the front of the treatment wheel so that the treatment agent is scratched on the surface of the leathe...
