Abstract

The patent relates to a polyether-containing leather brightener composition, which is composed of trimethoxysilane propyl vinyl ether, organosilicon glycol interpolymer wax, perfluoropolyether oil, perfluoroalkyl ethyl acrylates, polyisobutylene and N-butyl-N-methylpyrrolidinium bis(trifluoromethyl sulfonyl)imide.

Description

technical field [0001] The invention relates to a brightener, especially a polyether-containing leather brightener composition. Background technique [0002] Leather brightener has excellent soft, smooth and bright functions, which can greatly enhance the water resistance, softness, anti-sticking and wet rub resistance of leather on the basis of retaining the original breathability of leather, making the leather itself more plump, The leather surface is smooth and delicate, comfortable to the touch and rich in silk feeling, which not only improves the quality level of the leather, but also prolongs the service life of the leather. [0003] CN104479562A relates to a leather brightener, which consists of the following components in parts by weight: snake oil: 5-10, polydimethylsiloxane: 9-15, acetone: 15-30, dodecylbenzenesulfonate Sodium acid: 4-8, fatty alcohol polyoxyethylene ether: 4-6, nitrocellulose: 1-5, glyceryl monostearate: 4-8, magnesium chloride: 1-3, water: 80-10...
