[0023] A preparation method for foam wallpaper, comprising the steps of:

[0024] (1) Take castor oil and add potassium hydroxide and anhydrous methanol according to the mass ratio of 100~120:1:4, stir and mix at 40~45°C for 4~6 hours to obtain a mixture, take the mixture according to the mass ratio of 5:1 and add the concentration of Mix sulfuric acid with a mass fraction of 30%, let stand for 30-40 minutes, take the upper layer, and distill under reduced pressure to obtain a reduced-pressure distillate;

[0025] (2) Take the vacuum distillate and add tris(2-hydroxyethyl) isocyanurate at a mass ratio of 2:1, then add n-butyl titanate with a mass ratio of 1~3% of the vacuum distillate, and blow in nitrogen Protect, heat up to 220~230°C, stir and mix for 2~3h, cool to room temperature, filter with suction, take the filter residue, wash it with deionized water, and rotate it to get the rotary evaporated product, take the rotary evaporated product according to the mass ratio of 1...

Abstract

The invention discloses foamed wallpaper, and belongs to the field of decorative materials. According to the wallpaper disclosed by the invention, sodium polyacrylate, tourmaline powder and inorganicnano anti-mold powder are used as raw materials, and an adhesive, a hardening agent, tackifying resin polyacrylate, polyamide and hydrogenated rosin are added to prepare a compound emulsion, so that mildew of a wallpaper adhesive is inhibited, and a long-lasting antibacterial effect is achieved; the hardening agent is added, so that ability of a base film to solidify and pulverize a wall surface is improved, and the wallpaper does not fall off in a large area; the tourmaline powder has a degradation effect on harmful gases and protects the environment and human bodies, moisture and alkaline substances of a construction wall surface are effectively prevented from being infiltrated to the outside, and an occurrence of phenomena that the wallpaper gets damp, gets mildew, gets black and is discolored is prevented. The method disclosed by the invention solves the problems that in current wallpaper, a stronger-pollution flame retardant is added into a printing layer and a foaming agent containing polyvinyl chloride is added into a foaming layer, so that produced pure paper wallpaper has a higher content of harmful substances, and surfaces of foaming holes are rough and easy to fall off.The invention provides a preparation method for the foamed wallpaper.

Description

technical field [0001] The invention belongs to the field of decorative materials, and in particular relates to a preparation method of foamed wallpaper. Background technique [0002] Wallpaper is one of the products belonging to the decorative material category. Wallpaper, also known as wallpaper, is a specially processed paper used to decorate walls. 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. When it is used, it will not emit harmful ingredients to human health, but its function is relatively single. [0003] With the development of the plastic industry, there has been a rubber-faced wallpaper. This kind of wallpaper does not foam, so the texture is relatively hard, which greatly improves the shortcomings of foam wallpaper. Waterproof, moisture...
