Decorative wall leather and its making method

Abstract

The decorative wall leather is formed from surface layer and bottom layer, the composition of surface layer comprises PVC base material 100, diisodecyl phthalate 30-60, chlorinated paraffin wax 0-25, barium-zinc liquid compound stabilizer 1-2, azoformamide 0-3, antimony oxide 0-5 and oil soluble dry film mildew inhibitor 0.2-1.5, and the composition of bottom layer contans PVC base material 100, diisodecyl phthalate 40-62, chlorinated paraffin wax 0-25, barium-zinc liquid compound stabilizer 1.5-3.5%, azoformamide 2-6, antimony oxide 2-8 and oil soluble dry film mildew inhibitor 0.2-2. Its preparation process includes the following steps: preparing materials, filtering, first knife coating, drying, secondary knife coating, drying, foaming, stripping, printing, embossing, edge-cutting, check finished product and packaging.

Description

technical field [0001] The invention relates to a production process of a wall decoration material, in particular to a production process of an artificial leather material for a wall. Background technique [0002] Traditional wall decoration materials use wallpaper or wall cloth, which are products produced by coating PVC plastic on paper base or cloth base. Affected by paper and cloth, the flame retardant performance is not high, and the moisture-proof and mildew-proof effect is not good. It is greatly restricted by the environment; this kind of product is low in thickness and thin in foam, and it is hard to hard to stick on the wall, so it cannot absorb or insulate sound; the product structure is composed of materials with different expansion coefficients layered together, resulting in edge warping during use , foaming and color change and other adverse consequences; and because the product is thin and poor in light resistance, it is easy to age. And existing common wall ...

Problems solved by technology

[0002] Traditional wall decoration materials use wallpaper or wall cloth, which are products produced by coating PVC plastic on paper base or cloth base. Affected by paper and cloth, the flame retardant performance is not high, and the moisture-proof and mildew-proof effect is not good. It is greatly restricted by the environment; this kind of product is low in thickness and thin in foam, and it is hard to hard to stick on the wall, so it cannot absorb or insulate sound; the product structure is composed of materials with different expansion coefficients layered together, resulting in edge warping during use , foaming and color change and other adverse consequences; and because the product is thin and poor in light resistance, it is easy to age

However, the existing ordinary wall leathers on the market are cloth-based materials without flame retardants and anti-mildew agents, and the fire, mildew, and moisture-proof effects are very poor.
