Problems solved by technology

The material is not limited to paper, but also includes other materials. In the decoration process, in order to improve the stain resistance of wallpaper, polymer wallpaper materials are often used, such as PVC wallpaper materials. Now, in order to improve the comprehensive performance of wallpaper, such as heat insulation, Sound insulation, the wallpaper material is often foamed, but the foaming speed is not easy to control, the size of the bubbles and the pore size of the bubbles are often scattered, after molding, the mechanical properties of the wallpaper are not balanced, and the sound insulation effect cannot be guaranteed

Abstract

The invention relates to a preparation method of wallpaper with a sound insulation effect. The preparation method comprises the steps of (1) mixing PVC (Polyvinyl Chloride) resin, an inorganic filler,dioctyl phthalate and magnesium stearate, extruding with a twin-screw extruder for granulating; (2) crushing granules prepared in the step (1), and sifting with a 200-mesh sieve to prepare mixed powder; (3) mixing the mixed powder prepared in the step (2) with a foaming agent, stirring the mixture for 1.5-2 h at a rotation speed of 600 r / min, then calendaring the mixture with a calender, coolingand winding the calendered product to obtain the wallpaper. Through compounding of the foaming agent, the foaming uniformity is increased, a microporous structure with better continuous degree is formed in a foaming process, and the sound absorption performance of the wallpaper is improved.

Description

technical field [0001] The invention belongs to the field of novel decorative materials, and in particular relates to a preparation method of wallpaper with sound insulation function. Background technique [0002] Wallpaper, also known as wallpaper, is an interior decoration material used to paste walls, and is widely used in interior decoration of houses, offices, hotels, hotels, etc. The material is not limited to paper, but also includes other materials. In the decoration process, in order to improve the stain resistance of wallpaper, polymer wallpaper materials are often used, such as PVC wallpaper materials. Now, in order to improve the comprehensive performance of wallpaper, such as heat insulation, For sound insulation, the wallpaper material is often foamed. However, the foaming speed is not easy to control, and the size and pore size of the bubbles are often scattered. After molding, the mechanical properties of the wallpaper are not balanced, and the sound insulati...
