Problems solved by technology

However, the main limiting factor of such products at present is that the adsorption function substances have weak adsorption capacity for formaldehyde, benzene, toluene and TVOC and cannot be organically combined with active compounds, thus failing to achieve a good formaldehyde removal effect.

Embodiment 1

[0018] Dissolve 5 grams of potassium permanganate in an appropriate amount of pure water, add 5 grams of emulsion binder, weigh 35 grams of nano-bamboo charcoal, 50 grams of basic alumina, and 5 grams of ammonium chloride, and soak them in potassium permanganate solution , stirred for 1 hour, after being fully infiltrated, took out and dried in vacuum at room temperature for 5 hours to obtain gas scavenger A. Take 1 gram of gas scavenger A and put it in a place containing 0.1mg / m 3 In the air environment of formaldehyde, the environmental space is 3m 3 After 24 hours, the formaldehyde gas content in the environmental space has dropped to 0.005mg / m 3 , the environmental pollution gas content meets the national standard.

Embodiment 2

[0020] Dissolve 5 grams of potassium permanganate in an appropriate amount of pure water, add 5 grams of emulsion binder, weigh 35 grams of nano-bamboo charcoal, 50 grams of magnesium hydroxide, and 5 grams of ammonium chloride, all soaked in the potassium permanganate solution, Stir for 5 hours, and after fully infiltrating, take it out and dry it under vacuum at room temperature for 5 hours to obtain gas scavenger B. Take 1 gram of gas scavenger B and put it in a place containing 0.1mg / m 3 In the air environment of formaldehyde, the environmental space is 3m 3 , 24 hours later, the formaldehyde gas content in the ambient space was reduced to 0.004mg / m 3 , the environmental pollution gas content meets the national standard.

Embodiment 3

[0022] Dissolve 6 grams of potassium permanganate in an appropriate amount of pure water, add 5 grams of emulsion binder, weigh 35 grams of nano-bamboo charcoal, 50 grams of magnesium hydroxide, and 4 grams of ammonium chloride, all soaked in the potassium permanganate solution, After being fully infiltrated, take it out and dry it under vacuum at room temperature for 5 hours to obtain gas scavenger C. Take 1 gram of gas scavenger C and place in a place containing 0.1mg / m 3 In the air environment of formaldehyde, the environmental space is 3m 3 , 24 hours later, the formaldehyde gas content in the environmental space was reduced to 0.003mg / m 3 , the environmental pollution gas content meets the national standard.

Abstract

The invention relates to an indoor polluted gas scavenger and a preparation method, and the method comprises the following steps: uniformly stirring nano-bamboo charcoal or the nano-bamboo charcoal after modification with the following raw materials according to the percentage, mixing, then adding an appropriate amount of water and a latex adhesive, stirring, fully infiltrating, and carrying out vacuum drying at normal temperature for preparation. The specific raw materials are as follows: the nano-bamboo charcoal or the nano-bamboo charcoal after the modification: 28-52%; potassium permanganate: 1-10%; basic aluminum oxide or magnesium hydroxide: 30-60%; ammonium chloride: 1-10%; and the latex adhesive: 2-8%. The invention belongs to the comprehensive technical field of environmental medicine, natural products, environmental protection, environment and human health, new materials and the like, and the product is mainly used for eliminating the harm caused by free formaldehyde, benzene, toluene and TVOC in the air, thereby further solving the relevant air pollution in rooms and relative closed spaces and being conductive to protecting the human health.

Description

【Technical field】 [0001] The invention relates to comprehensive technical fields such as environmental medicine, natural products and environmental protection, environment and human health, and new materials, and in particular to a scavenger for polluting gases in the air and its preparation method and application. 【Background technique】 [0002] Indoor pollutant gases are mainly released from home interior decorations, paints, furniture, etc., mainly formaldehyde, benzene, toluene, TVOC, etc. According to the test report of the national authoritative department on the indoor pollutant gases formaldehyde, benzene, TVOC, etc. in residential buildings, only 7.7% of them meet the requirements of the "Code for the Control of Indoor Environmental Pollution in Civil Buildings" promulgated by the state, among which formaldehyde is the most serious. The rate of exceeding the standard was 80.8%, and the most serious exceeded the standard by 21 times. According to an indoor air quali...
