Problems solved by technology

[0005] In the above two patents, the non-woven wallpaper base paper cannot achieve the effect of preventing and killing mosquitoes
To this end, the applicant applied for invention patents with patent application numbers: 2013102008215, 2013102008003, 2013102007458, 201310200822X. These patents respectively disclose the use of anti-mosquito fibers to prepare anti-mosquito non-woven wallpaper base paper. The price of anti-mosquito fibers used in this method Higher, which leads to an increase in production costs, which is only suitable for high-end products. For ordinary products, the cost of production still needs to be considered

Abstract

The invention relates to spray type mosquito-proofing non-woven wallpaper and a preparation method thereof. The wallpaper comprises non-woven wallpaper raw paper, wherein the non-woven wallpaper raw paper is prepared by mixed papermaking of functional fiber, wood pulp cellulose and adhesive or by mixed papermaking of functional fibers and wood pulp cellulose and on-machine coating by adopting the adhesive, wherein a mosquito-proofing agent is filled in the surface spray of the non-woven wallpaper raw paper, and the spray quantity of the mosquito-proofing agent is 5-30 percent of the paper quantity. By adopting the technical scheme, the knock down rate of the mosquito-proofing non-woven wallpaper produced by the invention in 60 minutes can be 97 percent, and the wallpaper product does not shrink in the processing process, does not have wet feeling, can be released completely, is good in toughness, and has a function of killing mosquitoes attached to the surface of the water paper.

Description

technical field [0001] The invention relates to a wallpaper, in particular to a functional wallpaper with anti-mosquito performance. Background technique [0002] Non-woven wallpaper is a new type of wall decoration material. It has the characteristics of rich colors, strong texture, bright patterns, green and environmental protection, convenient construction, reasonable price, noble and elegant decorative effects, etc., which is unmatched by other interior decoration materials. However, the previous wallpaper base paper used wood pulp fiber as the basic material. This kind of wallpaper is cheap, and its disadvantages are poor performance, water resistance, inconvenient cleaning, and inconvenient construction. Because wood pulp fiber can absorb a large amount of water in the air, the surface There will be a sense of humidity from time to time, and black spots will appear after a long time. When replacing the wallpaper base paper, due to its own poor strength, the peeling i...
