Problems solved by technology

However, the flame retardant effect of the wallpaper base paper obtained by the existing method is not durable, and the whiteness is too low
Often when the base paper just produced is tested, the wallpaper base paper can have a good flame retardant effect and high whiteness; but when it is put into the warehouse for 3 to 7 days and then sampled again, the wallpaper base paper will produce flame retardancy. The problem of reduced or lost flame retardancy, uneven color change, reduced whiteness, yellowing and darkening

Abstract

The invention relates to flame-retardant wallpaper base paper and a preparation method thereof and belongs to processing of flame-retardant nonwoven wallpaper base paper. The flame-retardant wallpaper base paper is prepared through the following components in parts by weight: 65 to 70 parts of wood pulp cellulose, 15 to 20 parts of chemical fibers, 10 to 15 parts of rubber latex, 1 to 3 parts of fire retardant, 1 to 3 parts of modifier, 0.1 to 0.5 parts of dry strength agent, 0.1 to 0.5 parts of wet strength agent and 0.05 to 0.2 parts of fluorescent agent. The preparation method comprises the following steps: uniformly mixing the flame retardant and the modifier at a mass ratio, thereby obtaining a modified flame-retardant solution; immediately adding the modified flame-retardant solution into crylic acid rubber latex, and uniformly mixing, thereby obtaining an a glue applying solution; soaking a base paper semifinished product in the glue applying solution, thereby obtaining the flame-retardant wallpaper base paper with stable flame-retardant property and low cost. The flame-retardant wallpaper base paper is high in whiteness and good in flame-retardant property, the flame-retardant property of the flame-retardant wallpaper base paper can reach a B1 fire-retardant standard, the high flame-retardant property can be maintained after the base paper is used for a long time, and the base paper unlikely turns yellow after being used for a long time.

Description

technical field [0001] The invention belongs to the field of flame-retardant non-woven wallpaper base paper materials, and in particular relates to a flame-retardant wallpaper base paper and a preparation method thereof. Background technique [0002] Wallpaper is the most commonly used material in wall decoration at present. When the socket leaks electricity or there is an open flame, the flame retardant effect of the wall wallpaper base paper can prevent the spread of the fire. Wallpaper base paper is the main base material for the production of flame-retardant wallpaper. It can be coated with a flame-retardant adhesive layer on the wallpaper base paper for coloring, printing, and embossing to make exquisite flame-retardant wallpaper. However, the existing flame-retardant wallpapers cannot be flame-retardant on both sides. Often, the side coated with the flame-retardant adhesive layer can be flame-retardant against open flames, but the side of the base paper of the wallpap...
