Polymer foamed PU synthetic leather

Abstract

The invention discloses polymer foamed PU synthetic leather, comprising an abrasion resistant layer. The bottom of the abrasion resistant layer is coated with anticorrosive coating. The bottom of acidand alkali resistant coating is fixedly connected to an acid and alkali resistant layer. The bottom of the acid and alkali resistant layer is coated with waterproof coating. The bottom of the waterproof coating is fixedly connected to an anti-ageing layer. The bottom of the anti-ageing layer is coated with anti-ageing coating. According to the polymer foamed PU synthetic leather, influences of accident scratches or abrasion on service lifetime of PU synthetic leather when the PU synthetic leather is in use are avoided, acid and alkali corrosion influences on the surface of the polymer foamedPU synthetic leather can be effectively isolated, a defect that traditional PU synthetic leather is not resistant to acids or alkalis is solved, using performance of PU synthetic leather is improved,the PU synthetic leather has good waterproof performance and laundering durability, the PU synthetic leather is lighter, softer and increased in dermis sense, ageing damage of the PU synthetic leatheris prevented, and service lifetime of the PU synthetic leather is prolonged.

Description

technical field [0001] The invention relates to the technical field of synthetic leather, in particular to polymer foamed PU synthetic leather. Background technique [0002] Synthetic leather is a term relative to "leather", also known as artificial leather or synthetic leather. There is no standard term for synthetic leather in my country. Generally, it is divided into PVC artificial leather and PU synthetic leather according to the type of surface resin, and the back of PU synthetic leather It is a cloth base, easy to burn and melt, and has many advantages that PVC synthetic leather cannot match. It is an ideal material to replace natural leather. [0003] A plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. It is usually made of impregnated non-woven fabric as a mesh layer and a microporous polyurethane layer as a grain layer. The front and back sides are very similar to leather. It is similar to nat...
