Example Embodiment

[0028] Example 1

[0029] S1. The ink layer is formed in the surface of the wood pulp paper layer to obtain a wallpaper semi-finished product, wherein the wood pulp paper layer has a thickness of 1 mm, and the thickness of the ink layer is 0.3 mm;

[0030] S2. Preparation of flame retardant coatings

[0031] 50 parts of deionized water were added to the reaction vessel, and the mixer was added to the mixer, and the mixture was stirred at a frequency of 300 rpm. After mixing uniform, 2 parts of the phosphate salt dispersant, 5 parts of antimony After 20 parts of the modified manganese oxide colloid, the flame retardant is dissociated with a frequency of 25 kHz, and a 1 part of the hydroxymethylcellulose thickener is added inside, and the flame retardant coating can be obtained after stirring 20 min. .

[0032] The preparation step of the modified manganese oxide colloid is to be placed in the ball milling in the ball mill. After the particle size is 5-10 nm, the cooling is taken af...

Abstract

The invention discloses mildew-proof and flame-retardant wallpaper and a preparation method thereof. According to the invention, the mildew-proof layer is arranged on the surface of the wallpaper, so that the antibacterial ability of the wallpaper is enhanced, and the self-cleaning performance of the surface of the wallpaper is enhanced by virtue of the decomposition ability of N-doped zinc oxide contained in the mildew-proof layer; and birnessite used in the flame-retardant layer is utilized to adsorb moisture and decompose formaldehyde, so that the environment-friendly property of the wallpaper is enhanced while the ink layer is protected from stripping, the harm to a human body is reduced, and the wallpaper has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of wallpaper, in particular to a mold-proof and flame-retardant wallpaper and a preparation method thereof. Background technique [0002] As a new type of wall decoration material, wallpaper has the advantages of being beautiful, cheap and easy to use. Its application has become more and more widespread in recent years. The process is generally to coat, print or cover the surface of wood pulp base paper, and then leave the factory for use after cutting and shaping. However, due to the limitations of the raw materials and process of wallpaper production, the flame retardant performance of wallpaper is better than that of previous decorative materials. It has declined, and paper-based materials still have the disadvantages of being easy to absorb water and not being mildew-proof. Therefore, the current market urgently needs a wallpaper with both flame-retardant and mildew-proof effects to meet the demand. Co...
