Ecological functional wallpaper base paper mixed with dihydrate phosphogypsum whiskers and preparation method thereof

Abstract

The invention provides ecological functional type wallpaper raw paper doped with dihydrate phosgypsum crystal whiskers and a preparation method thereof. The ecological functional type wallpaper raw paper is prepared from the following raw materials in weight percent: 60%-80% of paper pulp, 9%-17% of the dihydrate phosgypsum crystal whiskers, 8%-15% of a humidifying agent, 1%-3% of starch, 1%-2% of a sizing agent, 0.1%-1% of a wet strength agent and 1%-2% of an inorganic auxiliary agent, wherein the humidifying agent is modified diatomite and / or modified sepiolite, and the whiteness is more than or equal to 95%; the sum of the raw materials is 100%. The prepared wallpaper raw paper is ecological and environmentally friendly, has the effects of humidifying and absorbing sounds, and preserving and insulating heat, and also has the characteristics of high strength, wear resistance, bacterium resistance, fire resistance and the like.

Description

technical field [0001] The invention relates to the technical field of interior decoration materials, in particular to an ecological functional wallpaper base paper mixed with dihydrate phosphogypsum whiskers. Background technique [0002] With the continuous improvement of modern people's living standards, wallpaper is more and more valued as an interior wall decoration material. Bleached chemical wood pulp is usually used to produce wallpaper base paper, and then processed by different processes, such as coating, printing, embossing or surface coating, and finally cut and packaged before leaving the factory. There are many types of wallpaper, such as non-woven wallpaper, resin wallpaper, pure paper wallpaper, fabric wallpaper and so on. [0003] In recent years, the concept of "green environmental protection" has been put forward, and the use of resin wallpaper has been restricted. Pure paper wallpaper is one of the widely used indoor wall decoration wallpapers. It is bas...

Problems solved by technology

At present, most of the phosphogypsum whiskers on the market are hemihydrate phosphogypsum whiskers with high production cost. Because the hemihydrate and anhydrous phosphogypsum whiskers are prone to hydration reaction after contacting with water, the crystal structure and performance will be destroyed and lose In addition, its high solubility will generate a large amount of calcium ions and sulfate ions in the white water system of the paper machine, which will easily lead to a series of problems such as an increase in the amount of chemicals in the wet end of the paper machine and a decrease in the running performance of the paper machine. Various modifications are required to make paper-making fillers, which greatly increases the cost

Although there have been many reports on the technology of using phosphogypsum hemihydrate whiskers as paper-making fillers, there are still few research reports on phosphogypsum dihydrate whiskers, and no related patents have been seen in China so far.
