Water-based matt scratch-resistant soft synthetic leather

Abstract

The invention relates to the field of manufacture of water-based synthetic leather, in particular to water-based matt scratch-resistant soft synthetic leather. The water-based matt scratch-resistant soft synthetic leather comprises a base cloth layer, a wet process polyurethane coating, a dry process polyurethane layer, a pearly luster layer, a matt treatment layer and a water-based matt treatmentlayer, wherein the wet process polyurethane coating is coated onto the base cloth; the dry process polyurethane layer is coated onto the wet process polyurethane coating; the pearly luster layer is printed onto the dry process polyurethane layer by high solid printing; the matt treatment layer is coated onto the pearly luster layer through template coating; the water-based matt treatment layer iscoated onto the matt treatment layer through template coating. Through study on the wet process polyurethane layer and the dry process polyurethane layer, the hand feeling of the synthetic leather issoft; the fullness degree of film coating is high; the toughness is very good; the wear resistance and scratch resistance are realized; through the arrangement of the water-based matt treatment layer, the hand feeling fullness and the texture fineness of the synthetic leather are better than those of a conventional solvent type product; the made synthetic leather has ultra-weak odor; the environment-friendly effect is achieved; the pure water-based performance and environment-friendly effects are achieved; no heavy metal and no free formaldehyde exist; APEO (alkylphenol ethoxylates) and potassium phthalate are not contained; no toxic and harmful ingredients such as isocyanate remains.

Description

technical field [0001] The invention relates to the field of water-based synthetic leather production, in particular to a water-based matte, scratch-resistant and soft synthetic leather. Background technique [0002] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. Usually, the impregnated non-woven fabric is used as the mesh layer, and the microporous polyurethane layer is used as the grain layer. Its front and back are very similar to real leather, and has a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather. Widely used in making shoes, boots, bags and ball games. The materials used to make leather in the early days were all taken from animal skins such as cowhide or pigskin. Although these animal leather products have good elasticity and wear resistance, the materials available are limited and the cost performance is h...

AI Technical Summary

Problems solved by technology

The use of artificial leather and synthetic leather to decorate bags, clothing, shoes, vehicles and furniture has been increasingly recognized by the market. Its wide application range, large quantity and variety are beyond the satisfaction of traditional natural leather.

[0004] However, most of the synthetic leather currently on the market has some problems, such as soft and hard hand feeling, poor flexibility, poor wear resistance, easy yellowing, not durable elasticity, synthetic leather often has a pungent smell, and is even toxic.
