Abstract

The invention discloses a preparation method for anti-ultraviolet synthetic leather. The preparation method comprises the following steps: (1) surface layer mixing and blending: putting weighed raw materials which are prepared from 100 parts by weight of polyvinyl chloride resin, 10-20 parts by weight of nano ZnO-nano TiO2 compound powder, 3-6 parts by weight of a thickener, 1-3 parts by weight ofa defoamer and 0-3 parts by weight of a pigment into a high speed dispersing mixing machine to be stirred and mixed to be uniformly mixed; (2) surface layer calendaring molding; (3) surface layer andbase material laminating; and (4) surface treatment. The synthetic leather prepared by the preparation method not only has good anti-ultraviolet performance, but also has excellent performance such as ageing resistance, bacterial resistance, flexibility, smoothness and durability.

Description

technical field [0001] The invention belongs to the technical field of synthetic leather, in particular to a preparation method of ultraviolet-resistant synthetic leather. Background technique [0002] At present, synthetic leather products have been widely used in the production of luggage, clothing, footwear and other product fields. Traditional synthetic leather does not have anti-ultraviolet, antibacterial and other functions, and the surface of synthetic leather has poor performance such as anti-aging, smoothness and wear resistance, which cannot meet the needs of use. The existing synthetic leather preparation process is difficult to combine these properties with ordinary synthetic leather, and it is impossible to prepare UV-resistant synthetic leather that meets the needs of use. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a preparation method of anti-ultraviolet syn...
