Problems solved by technology

[0005] Some chalk rubbing products currently on the market mainly have the following deficiencies: 1. The hand feel is difficult to last, and the gloss is low and oil-free; 2. The waterproof effect generally has no oil-proof effect; Natural; 4 High temperature resistance is obviously low and cannot be used for more demanding post-treatment processes of synthetic leather

Abstract

The invention discloses a high-efficiency water-proof anti-oil high temperature-resisting dedusting treating agent for synthetic leather, relating to a high temperature-resisting dedusting treating agent, comprising 18-25 parts of temperature-resistant resin, 7-12 parts of polyurethane bright resin, 23-32 parts of dimethyl formamide, 8-13 parts of ethyl acetate, 15-23 parts of butyl acetate, 2-4 parts of micronized organic polymer wax, 4-7 parts of micronized silicon dioxide, 2-7 parts of oily water-proof anti-oil aid, 1-3 parts of modified organosilicon aid, and 1-3 parts of grease. The dedusting treating agent disclosed herein has high temperature resistance, excellent water-proof anti-oil effect, charred feeling, extremely good handle, oil feel and waxy feel, and strong leather feeling.

Description

Technical field: [0001] The invention relates to a high-temperature-resistant chalk treatment agent, in particular to a high-temperature-resistant chalk treatment agent with high water and oil resistance for synthetic leather. Background technique: [0002] PU synthetic leather, with its various excellent properties, has become the best product to replace natural leather. There are three main characteristics of the popularity of synthetic leather products in the world: First, young people like leather products. This consumer group pursues challenges, has unique personality, advanced consumption, and respects fashion. Synthetic leather products are catering to the demand; second, colors and styles change rapidly. The speed of research and development of new products is fast, and new varieties are replaced within a year and a half or even a month or two, which satisfies people's awareness of innovation in life; the third is the advantage of price and quality. Compared with nat...
