Abstract

The invention discloses a nanometer pigment plaster for leather, which comprises the following compositions in mass percentage: 5 to 20 percent of inorganic nanometer pigment, 0.05 to 0.5 percent of dispersant, 0.05 to 5 percent of composite stabilizer, 0.05 to 0.5 percent of dispersion stability additive and 74 to 94.85 percent of water. After the pigment plaster is used for coating leather, thediameter of an inhibition ring in an antibacterial mildewproof experiment is between 39 and 45 mm; the chromatism value Delta E before and after ultraviolet accelerated irradiation is between 1.82 and 2.12; and the index of flame retardant oxygen is between 29 and 32 percent. The invention also discloses a method for preparing the nanometer pigment plaster for the leather. The nanometer pigment plaster for the leather has good antibacterial mildewproof performance, ultraviolet irradiation resistant performance, flame retardant performance and the like, has wide use range, can be used in leather coating and can be used in paint and other industries.

Description

technical field The invention belongs to the technical field of leather pigment paste and its preparation method, and in particular relates to a leather nano pigment paste and a method thereof. Background technique As a leather coloring material, pigment paste is widely used in the finishing process of various leathers. It is mainly composed of inorganic pigments, organic pigments or organic dyes as the coloring matrix, and is prepared by adding adhesives, dispersants, plasticizers, etc. When used It can be mixed with resin film-forming agent to form a finishing paste, which can be used for the bottom and middle layers of various leathers (Li Yuntao, Chen Junzhi. Preparation of a new type of casein-free pigment paste [J]. Journal of Jinan University, 2006, 27 (5) 729 ~732). But the role of common pigment paste in leather coating is only to cover the slight defect and the background color of leather on the leather surface, to give leather coating various colors, and to incre...
