[0052] The wood pulp ratio is softwood pulp:hardwood pulp=17:95.

[0053] The modified chemical fibers are polyester fibers with a fineness of 1-5D and a length of 3-5mm.

[0054] The modified chemical fiber is prepared by the following method:

[0055] 1) Soak the chemical fibers in 20% ethanol solution for 3 hours, and the amount of ethanol solution is based on the total immersion of the chemical fibers;

[0056] 2) Add dopamine hydrochloride which is 1 / 4 of the mass of the chemical fiber and n-dodecanethiol which is 1 / 20 the mass of the chemical fiber to the mixture in step (1) and mix evenly, stir at 30°C for 12 ...

Embodiment 3

[0069] A high-strength environmental-friendly antibacterial wallpaper base paper is prepared from the following raw materials in parts by weight: 80 parts of wood pulp, 40 parts of modified chemical fiber, 30 parts of resin, 10 parts of gas adsorbent, 10 parts of wet strength agent, disperse 10 parts of agent, 3 parts of antibacterial agent, 5 parts of synergist.

[0070] The wood pulp ratio is softwood pulp:hardwood pulp=20:100.

[0071] The modified chemical fibers are polyester fibers with a fineness of 1-5D and a length of 3-5mm.

[0072] The modified chemical fiber is prepared by the following method:

[0073] 1) Soak the chemical fibers in 20% ethanol solution for 3 hours, and the amount of ethanol solution is based on the total immersion of the chemical fibers;

[0074] 2) Add dopamine hydrochloride which is 1 / 4 of the mass of the chemical fiber and n-dodecanethiol which is 1 / 20 the mass of the chemical fiber to the mixture in step (1) and mix evenly, stir at 30°C for...

Abstract

The invention discloses high-strength environment-friendly antibacterial wallpaper base paper, and belongs to the technical field of papermaking. The base paper is prepared from the following raw materials in parts by weight: 60-80 parts of wood pulp, 20-40 parts of modified chemical fibers, 20-30 parts of resin, 5-10 parts of a gas adsorbent, 6-10 parts of a wet strength agent, 6-10 parts of a dispersing agent, 1-3 parts of a bacteriostatic agent and 1-5 parts of a synergist. By effectively modifying the chemical fibers and adding the synergist with a synergistic effect, the moisture resistance of the wallpaper base paper is greatly optimized, and meanwhile, the mechanical strength of the base paper is greatly improved. The wallpaper base paper is smooth and moistureproof, does not curl or deform after long-term use, has greatly prolonged service life, also has antibacterial and deodorant effects, and has broad market prospects.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a high-strength environment-friendly antibacterial wallpaper base paper and a preparation method thereof. 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, etc., 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. .
