Problems solved by technology

CN1168924A contains mineral oil, which further improves the miscibility and low-temperature toughness of high molecular polymers and waxes, but affects dust resistance
Glycerin is selected for use in CN1095395A, because it is water-soluble polyalcohol, anti-water is unsatisfactory, and its excipient effect is unsatisfactory, is liquid state
However, due to the absence of high molecular polymers, the abrasion resistance is not ideal
Moreover, the price of higher carbon alcohols with carbon number C>30 is expensive

Abstract

A waxy composition for surface finishing of leather and its products. It is mainly composed of wax, high molecular polymer emulsion, long carbon chain fatty alcohol, fatty amide, surfactant and water. The composition does not contain organic solvents, water-soluble organic alcohols, or mineral oil. Fatty amide is used as a co-solvent for the coating composition system. Fatty amide has good mutual solubility with wax, fatty alcohol, high molecular polymer and other solid components, which can improve the stability of the coating composition system and ensure the continuous and dense coating film , and avoid the disadvantages of mineral oil and low-molecular water-soluble alcohol in the composition. Used for surface coating of leather and its products, with natural luster, good water resistance, dust resistance, dry and wet friction resistance, convenient and safe use, and less pollution.

Description

technical field [0001] The invention belongs to the technical field of special waxes, in particular to a wax-containing composition used for surface coating of leather and its products. Background technique [0002] Leather finishing is a post-treatment process in the processing of leather and its products. The finishing agent forms a coating film on the top layer of the leather, mainly to endow the leather and its products with natural luster, water resistance, dust resistance and abrasion resistance, protect the leather and improve the grade of the product. [0003] Due to the pursuit of genuine leather feeling and natural feeling of leather, more and more attention has been paid to leather and product finishing agents containing wax components. US5743949 and US5746812 respectively propose a composition in which wax is stably dispersed in water for leather finishing. However, the film-forming components of these two patents are mainly waxes, which have unsatisfactory abr...
