A kind of composite household decorative wallpaper synthetic leather and preparation method thereof

Abstract

A composite home decorative wall covering synthetic leather, comprising a substrate layer, an intermediate layer, and a surface layer. The substrate layer, the intermediate layer and the surface layer are connected by means of hot-pressing lamination; the substrate layer comprises the following components in parts by weight: 100 parts of PVC resin, 30-40 parts of calcium carbonate, 50-60 parts of a plasticizer, and 5-10 parts of a stabilizer. The intermediate layer comprises the following components in parts by weight: 100 parts of PVC resin, 50-60 parts of a plasticizer, 8-16 parts of bamboo modal fibers and 16-32 parts of nano aluminum oxide. The surface layer comprises the following components in parts by weight: 100 parts of PVC resin, 30-40 parts of glass fibers, 15-25 parts of carbon fibers and 5-10 parts of nano aluminum oxide. The preparation method comprises the following steps: (1) preparation of the intermediate layer; (2) preparation of the substrate layer; (3) preparation of the surface layer; (4) hot-pressing lamination.

Description

technical field [0001] The invention relates to a composite household decorative wallpaper synthetic leather and a preparation method thereof. Background technique [0002] With the continuous development of society, people's living standards are improving day by day, and people's requirements for living environment are also increasing day by day. At present, indoor wall decoration mainly uses decorative wallpaper and natural leather. The wallpaper is not resistant to moisture, light, and easy to break, so it is difficult to achieve high-end decorative effects. For natural leather, due to the constraints of natural conditions and the gradual strengthening of the awareness of animal protection around the world, natural leather is decreasing year by year. At present, the composite home decorative wallpaper synthetic leather developed on the market generally includes an outer layer and a base. The outer layer is generally made by mixing PVC resin with various modifiers, and t...

AI Technical Summary

Problems solved by technology

At present, the composite home decorative wallpaper synthetic leather developed on the market generally includes an outer layer and a base. The outer layer is generally made by mixing PVC resin with various modifiers, and the base is generally a fiber layer. However, such synthetic leather The wear resistance of leather is not good, the anti-corrosion and acid-proof performance is poor, and the base and outer layer are often not firm and easy to split after hot pressing
