Description
Technical Field
The invention belongs to the technical field of indoor air purification, and particularly relates to a formaldehyde purification composition and a preparation method and application thereof.
Background
The like products of the formaldehyde scavenger sold in the domestic market at present mainly comprise photocatalyst, chemical neutralization and sealing and physical adsorption. The photocatalyst is a sum of photocatalytic materials represented by titanium dioxide, is coated on the surface of a base material, generates a catalytic degradation function under the action of light, can remove free formaldehyde in the air, and is the most widely used formaldehyde scavenger in the current market. The existing problem is that the ultraviolet ray can only be directly irradiated to take effect, and the method has limitation. The chemical neutralization closed product is an amino compound which can perform dehydration reaction with formaldehyde, and then a water-soluble wax solution and other plant components are utilized to form a protective film on the surface of a base material to seal and prevent formaldehyde from releasing, and the defect is that the side effect of a strong oxidant can damage other products such as painted surfaces and metal utensils; the treatment of the sealing technology only covers up the pollution source and can continuously release once the sealing layer is damaged. The physical adsorption products mainly comprise plants, traditional Chinese medicines, activated carbon and chitosan, which belong to adsorption types and are called formaldehyde catching agents. There are problems as follows: formaldehyde in the air is physically adsorbed, so that the pollution source cannot be thoroughly decomposed; passive treatment, weak adsorption capacity and low efficiency.
The product is prepared from plant extracts such as sodium humate, phytic acid and the like, and the selected materials are food-grade raw materials, so that the product is environment-friendly, non-toxic, harmless to human bodies, free of secondary pollution, high in purification clearance rate and high in sterilization effect. The liquid can be used for being prepared into liquid by a compression spray gun and sprayed in space to remove harmful substances such as free formaldehyde, acetaldehyde and the like, and the solid can be added into diatomite, bei Zaoni, inner wall paint, cellulose, rubber powder and urea-formaldehyde glue to decompose a large amount of released and residual formaldehyde, and other performance indexes of the inner wall paint are not influenced.
Comprises the following steps: new chemical substances are easy to produce, and secondary pollution is caused; once the chemical reaction is finished, the effect is lost, the continuously volatilized formaldehyde cannot be treated, and the effect can be achieved only in a short time; the semiconductor air purifying material which needs specific functions adsorbs and decomposes harmful substances in the air in a physical mode, a chemical mode and the like, and the application of the air purifying material is a mode for effectively controlling air pollution sources. The known patent technology 'algae-calcium mineral air purification medium and preparation method and application thereof' (CN 201511029041.4) consists of algae mineral micro powder, calcium micro powder, catalytic micro powder, mineral modifier, liquid-phase medium and photocatalyst, has excellent adsorption and purification performance, but is easy to passivate under the purification of continuous concentration; the patent 'composite air purifying agent containing nano mineral substance and preparation method thereof' (CN201010112863. X) is composed of natural mineral, molecular sieve, photocatalyst, modifier, foaming agent and surfactant, has high decomposition efficiency on organic pollutants in the air, and has the defects that the purifying material is a selective adsorption material and the purifying type is not wide; the photocatalyst multifunctional diatom purification particle and the preparation method thereof (CN 201310142911.3) disclosed by the patent comprise diatom, attapulgite, zeolite powder, sepiolite, anion powder, far infrared ceramic powder, kaolin and nano photocatalyst, can decompose harmful substances such as formaldehyde and the like, solve the technical defect that products such as active carbon and the like only adsorb and do not decompose, but have the defects in efficiency and adsorption of fine particles (PM 2.5 and PM 10).
The common characteristics of the known patent technologies are that the porous environment mineral powder and the photocatalytic component are fully utilized for granulation, the adsorption and decomposition amount is limited, and the removal and decomposition speed is slow. In the known technology, an oxidation type air purification material and a preparation method thereof (CN 1021101008A), the effect of improving the purification effect is disclosed by soaking an inorganic adsorption material in a 5-20% inorganic oxidant aqueous solution for 18-36 h and then drying. However, the method of loading the oxidizing agent by soaking only has the disadvantage that the loading is insufficient and weak, and the purification performance is not durable.
Harmful gas in the air and scavenging material are through lasting absorption, desorption, decomposition constantly, and its vision is that the perception can not be experienced in the use, can evaluate scavenging material's purifying effect only through professional detecting instrument, are difficult to in time, judge the validity of absorption, decomposition in real time when using.
