[0025] Take soybeans and place them in a mortar and mash them for 30 minutes, soak the mashed soybeans with absolute ethanol for 2 hours, filter, remove the filter residue, and obtain soybean extracts. In parts by weight, take 50 parts of butyl acrylate, 15 parts of methyl Put hydroxyethyl acrylate and 30 parts of styrene in a beaker and stir for 15 minutes to obtain a mixed monomer; take 8 mL of soybean extract, 90 mL of deionized water and 40 mL of a mixed monomer and mix and stir for 10 minutes to obtain a monomer pre-emulsion, and another 4 mL Soybean extract and 40mL deionized water were added to the four-necked flask as the reaction bottom solution; 4.5g of ammonium persulfate was dissolved in 25mL of deionized water to obtain the initiator, and the above-mentioned four-necked flask was moved into a water bath at 80°C. Add two-fifths of the monomer pre-emulsion and one-third of the initiator into the four-necked flask, stir and react, and after the blue phase appears in t...

Abstract

The invention relates to the technical field of wallpaper preparation, in particular to a preparation method of water-resistant wallpaper. The method comprises the steps that a self-made soybean extraction solution and a self-made mixed monomer are mixed and dispersed to obtain a monomer pre-emulsion, the self-made soybean extraction solution is mixed with deionized water to obtain a reaction basesolution, and an initiating agent and the monomer pre-emulsion are subjected to two-step emulsification and polymerization to obtain a latex solution; dried paper pulp is treated to obtain modified paper fibers, the modified paper fibers, the deionized water and liquid paraffin are mixed to obtain mixed paper pulp, and the mixed paper pulp is treated to obtain the water-resistant wallpaper. According to the preparation method, water-repellent lecithin is used as an emulsifier, ethylene groups are introduced into latex solution polymers, cross-linking polymerization can be achieved, the stability of the latex solution is improved, the latex solution is dried and solidified to form latex film, the bonding performance and waterproof performance of the latex film can be improved, carboxyl inthe liquid paraffin can conduct an esterification reaction with hydroxyl, the hydrophily of the paper fibers is lowered, the water resistance of the wallpaper is improved accordingly, and the application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of wallpaper preparation, in particular to a preparation method of water-resistant wallpaper. Background technique [0002] Wallpaper, also known as wallpaper, is a widely used interior decoration material. Because wallpaper has the characteristics of various colors, rich patterns, luxurious style, safety and environmental protection, convenient construction, and reasonable price, which are incomparable to many other interior decoration materials, it has been widely popularized in developed countries and regions such as Europe, America, Southeast Asia, and Japan. . Wallpapers are divided into many categories, such as coated wallpapers, laminated wallpapers, embossed wallpapers, etc. Usually bleached chemical wood pulp is used to produce 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. Be...
