Abstract

The invention relates to an anti-microbial synthetic leather and a preparation method thereof. The anti-microbial synthetic leather is prepared from the following components by weight: 35 to 50 parts of thermoplastic polyurethane, 20 to 35 parts of diisocyanate, 15 to 25 parts of melamine copolymer resin, 7 to 9 parts of a nanometer titanium oxide-Ag anti-microbial agent, 3 to 5 parts of an auxiliary agent, 4 to 8 parts of honey and 1 to 3 parts of elm powder. The synthetic leather has wear resistance, moisture permeability and air permeability, reduces potential threat to the environment and the human body, can improve smoothness and cold-thermal fatigue performance, and has enhanced air permeability and moisture permeability, actual leather feel, wear resistance and service life.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to an antibacterial synthetic leather which is beneficial to improving the wear resistance, moisture permeability and air permeability of synthetic leather, and reduces potential threats to the environment and human body and a preparation method thereof. Background technique [0002] People need to use a large amount of synthetic leather in their daily life, and when producing synthetic leather, due to adding a large amount of plasticizer and other materials, the synthetic leather produced is not ideal in terms of luster and hand feeling. In order to achieve a better and more ideal use effect, the surface treatment of synthetic leather must be carried out in the production process of synthetic leather, so as to endow the surface of synthetic leather with smooth, soft, matting, waterproof, antifouling and other comfortable feel and beautiful appearance. . [0003] Polyurethane synth...
