Abstract

The invention relates to a method for producing multifunctional waterborne polyurethane superfine fiber decorative leather. According to the method, superfine fiber non-woven cloth is used as a base material, and the method comprises the following steps of: firstly, preparing mixed slurry containing the components of waterborne polyurethane, wood powder loaded with nano silver oxide and the like into superfine foam slurry by adopting a physical and mechanical stirring method; secondly, forming a functional coating on release paper by adopting a knife coating method, closely integrating the release paper with the base material, and drying, cooling and stripping to obtain superfine fiber non-woven cloth provided with the functional coating; and finally, performing various beautification processes on the superfine fiber non-woven cloth to obtain the multifunctional waterborne polyurethane superfine fiber decorative leather which has a variety of functions of decorating, purifying air, removing formaldehyde, deodorizing, sterilizing, adjusting moisture and the like and has a through microcellular structure. The multifunctional waterborne polyurethane superfine fiber decorative leather can be widely used in a variety of fields such as house wall decoration, hotel decoration, furniture soft package, automobile interior trim, jewelry package and the like.

Description

technical field [0001] The invention relates to the technical field of polyurethane synthetic leather, in particular to a production method of multifunctional water-based polyurethane superfine fiber decorative leather. Background technique [0002] 1. Technical progress of wallpaper [0003] The birthplace of wallpaper is Europe, and now it is the most popular in developed countries in northern Europe, with the best environmental protection and quality, followed by Southeast Asian countries, and the penetration rate of wallpaper in Japan and South Korea is as high as nearly 90%. No matter in terms of production technology, process, or use, compared with other building materials, it can be said that wallpaper is the least toxic. The main raw materials of modern new wallpaper are made of bark and chemically synthesized pulp, which is very natural. It will not emit ingredients harmful to human health. [0004] According to market research, most of the environmentally friendl...
