Embodiment 1

[0008] A production method of environment-friendly wallpaper base paper, which is characterized in that it is made of the following raw materials in parts by mass: bamboo fiber 40, wood pulp fiber 45, polyester fiber 25, sodium carboxymethyl cellulose 6, nano-bamboo carbon fiber 8, negative ion powder 5. The production steps are as follows: 1) After mixing bamboo fiber and wood pulp fiber, add water with a mass of 100 times, beat with a beater, and control the beating degree at 40-60 ° SR, wherein the bamboo fiber and wood pulp fiber After mixing, add nano-carbon fiber and nano-far-infrared negative ion powder into the mixed pulp evenly. Nano-carbon fiber is added 1-2 hours after the beating starts. After adding nano-carbon fiber, continue beating for 0.5-1 hour and add nano-far-infrared negative ions 2) adding 100 times of water to the polyester fiber and beating with a beater for 20 to 40 minutes to obtain a polyester fiber pulp; 3) mixing the bamboo fiber in the above steps ...

Abstract

The invention relates to a preparation method for environment-friendly type tile stocks. The preparation method is characterized in that: besides wood pulp fibers, a plurality of different fibrous raw materials and functional additives are added in the stuff of the tile stocks in the preparation process; and the environment-friendly type tile stocks are prepared through the operations of beating, paper making, squeezing, drying and reeling. Compared to common wallpaper, the tile stocks provided in the invention have the following advantages: the tile stocks have the functions of energy saving and heat insulation and can release negative ions and far infrared rays at the same time, thereby purifying air as well as benefiting health of human bodies.

Description

technical field [0001] The invention relates to a method for preparing a decorative base paper, in particular to a method for preparing an environment-friendly wallpaper base paper. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for interior decoration are also getting higher and higher. In addition to requiring smooth and beautiful walls, people also put forward new requirements for indoor air quality and thermal insulation performance of walls. Most of the currently widely used interior decorative wallpapers are based on wood pulp fibers. This kind of wallpaper is cheap, but its disadvantages are poor performance, water resistance, inconvenient cleaning, and inconvenient construction. Because wood pulp fibers can absorb a large amount of moisture in the air, The surface will feel wet from time to time, and black spots will appear after a long time. When replacing the wallpaper, due to its poor strength, i...
