Nanometer air purifying agent with bactericidal function and preparation method thereof

Abstract

The invention provides a nanometer air purifying agent with bactericidal function and a preparation method thereof. The nanometer air purifying agent contains tetrabutyl titanate, absolute ethyl alcohol, nitric acid, sulfamic acid, carbomite and distilled water; and organic titanic acid ester adopted in the invention is directly synthesized into a steady nanometer titanium dioxide microemulsion with a grain diameter of between 1 and 50nm through a screened special catalyst and an unique organic / inorganic emulsified dispersion stability system under certain temperature, time and pH value conditions. The nanometer air purifying agent can efficiently decompose formaldehyde and kill bacteria, and has a guarantee period more than 2 years; the nanometer air purifying agent has convenient use, can be effective for a long time after the use once, and has no pollution to the environment; and used raw materials and equipment are easy to purchase, and the process is simple and convenient and is easy to operate.

Description

technical field [0001] The invention belongs to the field of air purifiers, in particular to a nanoscale air purifier with bactericidal function and a preparation method thereof. Background technique [0002] The improvement of modern living standards has led to the popularization of interior decoration, but what follows is that the decoration materials have brought indoor air quality pollution. According to the statistics of the test results of the testing agency, the formaldehyde content in household pollution is generally 0.15mg / m 3 ~0.3mg / m 3 , up to 0.81mg / m 3 , 50%-200% higher than the national standard, with an average of 0.2mg / m 3 . [0003] At present, there are many methods for indoor air purification, including simple spice masking method, physical adsorption method using porous solid adsorbents such as activated carbon, ozonolysis method, photocatalytic oxidation decomposition method and biodegradation method using green plants to absorb. TiO 2 The reaction ...

Problems solved by technology

[0004] However, the particle size of nano-scale titanium dioxide is very small, and the current method for nano-scale air purifiers has the following disadvantages: most of the products are first synthesized powder and then dispersed and emulsified, the products produced in this way are neither stable nor effective; the other part The product is directly synthesized, but there are defects in the selection of the catalyst, and the stability and deodorization effect are poor
