Abstract

The invention discloses a preparation method of high-strength glass fiber non-woven wallpaper, and belongs to the technical field of decorative materials. The preparation method comprises the following steps: firstly, performing a reaction on rubber molecule-grafted glass fiber and pretreated aramid staple fiber to obtain modified glass fiber, then mixing the modified glass fiber with water, adding a dispersant, stirring for mixing to obtain mixed liquid, adjusting the pH of a mixed liquid system to 3-4 by using a hydrochloric acid solution, transferring the mixed liquid to a pulping machine, and pulping to obtain a pulp; transferring the pulp to a wet net forming machine, performing wet net forming, drying and performing hot rolling to obtain preformed glass fiber non-woven wallpaper, transferring the preformed glass fiber non-woven wallpaper to a blast dryer, and performing blast drying to obtain the high-strength glass fiber non-woven wallpaper. The glass fiber non-woven wallpaper prepared according to the preparation method provided by the invention has excellent breaking strength and fracture resistance, and has a breathability improved to a certain extent.

Description

technical field [0001] The invention discloses a preparation method of high-strength glass fiber non-woven wallpaper, which belongs to the technical field of decorative materials. Background technique [0002] In recent years, indoor fires have occurred frequently. Once the traditional wallpaper is burned, it will release a large amount of poisonous gas, or the wallpaper itself will burn, causing secondary damage. The use of firewall paper can effectively prevent the fire from spreading and reduce the damage caused by the fire. The glass fiber has a circular cross-section and a constant diameter, and the dimensional stability of the fiber is high. It has water and oil resistance, good acid and alkali resistance and heat resistance, and has good sound absorption effect. Glass fiber is used as the fiber raw material, and the wet non-woven production process is adopted to produce glass fiber wallpaper. This glass fiber wet-laid wallpaper has the advantages of non-combustibil...
