Problems solved by technology

Patent ZL200420009062.5 can efficiently and continuously purify free formaldehyde in the environment, but sticking harmful gas capture materials is troublesome and affects the appearance of the environment; the use of nano-titanium dioxide and other photocatalysts only has a certain effect on low-concentration formaldehyde, and the decomposition rate is slow. At present, the indoor air environment where the concentration of formaldehyde is generally greater than 0.20mg / m3, it is difficult to make the concentration of formaldehyde in the environment ≤0.10mg / m3 through photochemical reaction; while activated carbon, molecular sieve, etc. are physical adsorption of formaldehyde, the adsorption capacity is limited, and the ambient temperature rises Afterwards, the formaldehyde adsorbed by it will desorb again and be released into the air to pollute the environment; chitosan can carry out cross-linking reaction with formaldehyde in aqueous solution, but the reaction is very slow in gas phase medium, so patents 201220297018, 201220297019 and 201220297045 cannot draw The effect of removing formaldehyde

The invention discloses a formaldehyde purifying agent and application thereof in non-woven formaldehyde purifying wallpaper. The formaldehyde purifying agent is prepared from, by mass, 100 parts of an adsorbing agent, 1-100 parts of amino acid, 1-100 parts of chitosan and 1-100 parts of nano titanium phosphate. The adsorbing agent is prepared through a reaction of sepiolite and aluminum sulfate. The formaldehyde purifying agent can continuously and efficiently purify free formaldehyde in air. The purifying efficiency of the non-woven formaldehyde purifying wallpaper is larger than 97.5%. The non-woven formaldehyde purifying wallpaper can be widely applied to building interior decoration and has good economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of manufacturing functional decorative materials. More specifically, it relates to a formaldehyde wallpaper manufacturing field. Background technique [0002] Building decoration materials such as light wall partition boards, wall hanging boards, wall soft-covered substrates, wooden furniture, and wooden floors are basically produced using amino resins containing formaldehyde, which is the main cause of current indoor air pollution. [0003] Non-woven lithographic wallpaper is a decorative material made of non-woven paper as the base material, which is transferred to the pattern and color by multiple printing rollers. It is widely used in wall and ceiling decoration. [0004] In order to solve the indoor air pollution caused by decoration materials, the patent ZL200420009062.5 discloses a harmful gas capture material and its preparation method. A corresponding amount of harmful gas capture materials is hung...
