Oxidation type air purifying material and preparation method thereof

Abstract

The invention discloses an oxidation type air purifying material which has low cost and good air purifying effect and does not have secondary pollution. The oxidation type air purifying material is formed by loading an inorganic oxidant on an inorganic adsorbing material. The invention provides a method for preparing the material simultaneously, which comprises the following steps of: drying the inorganic adsorbing material till the moisture of the inorganic adsorbing material is less than 4 percent; preparing aqueous solution, which is at the concentration of between 5 and 20 percent (g / ml), of the inorganic oxidant; and immersing the aqueous solution of the inorganic oxidant in the inorganic adsorbing material for 18 to 36 hours, draining redundant liquid, and drying in a drying oven at the temperature of between 50 and 130 DEG C.

Description

technical field [0001] The invention relates to an air-purifying material and a preparation method thereof, in particular to an air-purifying material especially suitable for removing harmful gases released from decoration materials and a method for preparing the material. Background technique [0002] Along with the raising of people's living standard, people pay more and more attention to the decoration of the room. However, many decoration materials contain volatile toxic gases (such as formaldehyde, ammonia, benzene series substances, TVOC). It is reported that 90% of the newly renovated houses have exceeded the standard pollution, especially formaldehyde exceeding the standard is more serious. In order to overcome the infringement of poisonous gas on the human body, people have taken various methods to eliminate it. For example, people place activated carbon adsorption packs indoors in order to achieve the purpose of eliminating toxic gases through the adsorption of a...

Problems solved by technology

However, activated carbon itself does not have the effect of decomposing and eliminating harmful gases, and its adsorption rate is low. After the adsorption is saturated, the adsorbed harmful gases can be released again; although the ozone air disinfection machine has a certain elimination effect on formaldehyde and other gases, but the There will be a small amount of ozone in the tail gas emitted by the device, and ozone itself will pose a direct threat to the human living environment; green plants are used to remove formaldehyde, but because plants absorb formaldehyde through photosynthesis, it cannot be completed in the absence of light Moreover, the absorption rate of plants is low, the highest is only 20 micrograms per hour, and hundreds of plants need to be placed in a room to be effective; chemical sprays are used to eliminate, but it is easy to form secondary pollution
