Novel air purifying agent and preparation process thereof

Abstract

The invention provides a novel air purifying agent and a preparation process thereof. The novel air purifying agent is prepared from components as follows: nano titania, nano zinc oxide, a graphene oxide emulsion, modified sepiolite, modified zeolite, activated carbon, an activator, nitrate, butyl titanate, an ethanol solution, a dispersant and deionized water. The air purifying agent is preparedwith a simple preparation method, is good in stability and high in adsorption rate and can effectively remove harmful gases in the air, kill bacteria in the air, purify air and keep the indoor air fresh.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a novel air purifier and a preparation process thereof. Background technique [0002] At present, air purifiers are divided into two types, one is the air purifier that uses its own fragrance to cover up the odor, and the other is the air purifier that uses adsorption or chemical reaction to absorb or degrade harmful gases. The first one is just to cover up the odor, and does not remove the harmful gas itself; and the second one is currently divided into two types in the market, one is the traditional adsorption principle of activated carbon for adsorption. This method only absorbs the harmful gas, but does not completely remove it. The adsorbent needs to be replaced after the adsorption is saturated; the other is a new type of photocatalyst. Under light irradiation, the valence band electrons of the nano photocatalyst are excited to the conduction band, form...

Problems solved by technology

The air purifier described in this invention has a better air purification effect, but its preparation method has the following disadvantages: (1) mineral materials need to be activated by immersing them in acid or alkali, and then rinsed with clear water, resulting in a large amount of waste water in the preparation process It needs to be processed, and the pressure of environmental protection is high; (2) the activated and dried mineral materials need to be ultrafinely crushed to 800-2000 mesh, which consumes a lot of energy; (3) 5-60% of activated carbon is required, which increases the cost

These methods either have a low loading rate of nano-titanium dioxide and weak photocatalytic performance; or the process is complex and difficult to produce industrially; or the calcination temperature is high and the energy consumption is large, which has certain limitations.
