Description

Efficient self-cleaning air purifying agent for indoor decoration and preparation method thereof
Technical Field
The invention relates to the technical field of air purifiers, in particular to a high-efficiency self-cleaning air purifier for indoor decoration and a preparation method thereof.
Background
The air purifying agent is a product which is formed by utilizing the adsorption and decomposition principles of natural substances and through modern scientific and technical treatment and has the functions of eliminating harmful gases in the air and removing various peculiar smells.
A plurality of air purifiers are available on the market at present, and the fish and the dragon are mixed. There are several types in general: adsorption type air purifying materials such as activated carbon and bamboo charcoal; masked odor removal products, such as gel cartridges, air fresheners; and decomposed odor removing products, such as an earth-like decomposed air purifying agent and a Fukanghenjia decomposed air purifying agent.
The adsorption type air purifying agent is a purifying product for removing pollutants by utilizing the performances of physical adsorption, chemical adsorption, oxidation, catalytic oxidation, reduction and the like of activated carbon. The covering type odor removal product covers various odors in the air by utilizing the fragrance of aromatic hydrocarbons, so that the odor removal effect is achieved. Many air fresheners do not actually remove odors from the vehicle interior, but merely mask them with a favorable odor type. The decomposition type air purification products are rare in the market, the products are natural ores which have oxidation-reduction reaction with odor molecules in the air under high temperature and negative pressure through a base decomposition complexing technology to directly generate harmless gases such as carbon dioxide, nitrogen, hydrogen and the like, the peculiar smell is thoroughly removed, and solid particles generated after the products are decomposed can be used as flower fertilizers without secondary pollution.
At present, air pollution is increasingly serious, not only outdoors, but also indoors, and air is polluted already, and the world health organization determines indoor air pollution as a dangerous factor which is arranged in the eighth place and threatens human health as early as 2005. With the continuous improvement of the environment protection degree and the living quality of the living room, most people are more and more aware of the importance of the environment protection of the living room. As toxic substances such as formaldehyde, benzene, amine, xylene, TVOC and the like are inevitably emitted in the process of decorating a new house, and the toxic and harmful gases are harmful to human bodies. If people live in the house for a long time or stay in the office of the house, the immunity of people is low, the people can have headache and fever if the people live in the house for a long time, the people can have cancer or induce cardiovascular diseases and other diseases if the people live in the house for a long time. Among the various groups, the injury is greatest, especially for children, the elderly and pregnant women. Therefore, the treatment of various indoor air pollution is rapidly becoming one of the important points of the research of the environmental protection industry.
For example, CN201810094371.9 "a cleaning agent for indoor air prepared from attapulgite", which is an invention disclosed in china, is an invention which is capable of obtaining a highly active cleaning agent for indoor air by selecting natural attapulgite ore and processing the same, then performing a chaos treatment on the processed attapulgite, and then performing a mixing reaction treatment on the processed attapulgite and the processed air cleaner by processing the cleaning agent. Compared with the traditional attapulgite treating agent, the purifying agent has stronger activity, but the adsorption and desorption effects of the purifying agent are still to be improved, and the comprehensive function and the effect are weaker, so that the multifunctional requirements of consumer groups on the purifying agent in various aspects, such as faint scent, nerve calming, antibiosis, disinsection, self-cleaning recycling and the like, are not facilitated, the application of the purifying agent is greatly limited, and the problems are further solved.
