Base paper of wallpaper and preparation method thereof

Abstract

The invention discloses base paper of wallpaper. The base paper is prepared from the following components in parts by weight: 20 to 35 parts of bamboo fiber, 15 to 75 parts of broussonetia papyriferafiber, 10 to 25 parts of sodium carboxymethylcellulose, 12 to 18 parts of acrylic latex, 2 to 4 parts of flame retardant and 2 to 4 parts of modifier. A making method of the base paper comprises the following steps of making a base paper semi-finished product by utilizing the bamboo fiber and the broussonetia papyrifera fiber, making modified flame-retarding liquid and sizing liquid, impregnatingthe base paper semi-finished product with the sizing liquid, drying, gelling, calendering and coiling. The base paper has the beneficial effects that the base paper is not only good in flame retardingeffect, but also can keep the flame retardation of the flame retardant for a long time, and also has favorable antibacterial and bacteriostatic functions.

Description

technical field [0001] The invention relates to the field of wallpaper base paper materials, in particular to a wallpaper base paper and a preparation method thereof. Background technique [0002] Wall wallpaper is the most commonly used material in wall decoration. 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 wallpapers. However, the existing flame-retardant Wallpapers cannot be flame-retardant on both sides. Often, the side coated with a flame-retardant adhesive layer can be flame-retardant against open flames, but the base paper side of the wallpaper is not flame-retardant. The main reasons for the unsatisfactory ...
