Abstract

The invention discloses superfine fiber polyurethane suede leather capable of removing formaldehyde and a preparation method of the superfine fiber polyurethane suede leather. The preparation method comprises the following steps: superfine fiber suede leather is dried and impregnated in a formaldehyde removing treating agent; the superfine fiber suede leather is dried, and the superfine fiber polyurethane suede leather capable of removing formaldehyde can be obtained, wherein the formaldehyde removing treating agent contains a nano-TiO2 photocatalyst and a catalytic promoter. The catalytic promoter is added to the treating agent, and the required light source wavelength of nano-TiO2 for decomposing formaldehyde is extended from ultraviolet light smaller than 388 nanometers to common visible sunlight smaller than 600 nanometers, so that the superfine fiber polyurethane suede leather has a good formaldehyde removing effect in a common daily living environment.

Description

technical field [0001] The invention relates to a functional polyurethane synthetic leather and a preparation method thereof. Background technique [0002] Polyurethane microfiber suede (abbreviated as microfiber suede) is favored by consumers due to its stylish appearance and excellent touch. At present, it has been widely used in high-end models of high-end cars and high-end interior decoration. application. [0003] However, in the car cockpit and high-end interior decoration, due to the use of materials such as glue, sponge and paint, a certain amount of formaldehyde pollutants will appear in the car cockpit and indoor environment, which will affect the health of users. [0004] As a material in contact with the air, microfiber suede has the ability to remove formaldehyde, which can greatly improve the user experience of the product and expand the field of use of the product. Contents of the invention [0005] The object of the present invention is to provide a kind ...
