Air purifying agent and preparation method thereof

Abstract

The present invention discloses a preparation method of an air purifying agent. The method is as below: weighing 10 parts by weight of titanium dioxide and 20 parts by weight of silicon dioxide; adding titanium dioxide and silicon dioxide into an ultrasonic grinder for ultrafine grinding, and then conducting ultrasonic mixing in an ultrasonic blender to obtain a base material; then adding the base material into a reaction tank, adding 9 parts of propylene glycol monoethyl ether, 11 parts of dodecyl dimethyl benzyl ammonium chloride, 6 parts of a surfactant, 3 part of an organosilicon leveling agent and 8 parts of acetic acid into the reaction tank in order; then the reacting sufficiently for 1-1.5 h with the reaction temperature maintained at 20-25 DEG C; and finally adding 40 parts of deionized water, and neutralizing the solution with hydroxide sodium to the pH value of 6, precipitating to separate a supernatant to obtain the desired air purifying agent. The air purifying agent prepared by using titanium dioxide and silicon dioxide as the base materials can produce effects of sterilization, antibiosis, and decomposition of harmful gases.

Description

Technical field [0001] The invention relates to a preparation method of an air purifying agent. Background technique [0002] In the home decoration, environmental protection is emphasized. However, environmental protection decoration does not mean that the residue of harmful substances is completely eliminated. After home decoration, the release cycle of toxic gases in the decoration materials is generally 5-10 years, with a long residual time and great harm. In order to eliminate harmful gases in decoration, many scavengers and deodorizers using spraying, coating, covering, dilution, etc., have appeared on the market. Most of them are chemical raw materials. After use, they cannot eliminate harmful gas residues, and will produce secondary Secondary pollution. Ozone disinfection and negative ion generator can inhibit the growth of bacteria and viruses, remove peculiar smells, and clean the air, but they do not help eliminate the original pollutants in the air.

Problems solved by technology

However, activated carbon is derived from coal, which is limited to the country's protection of energy and its high preparation cost, high consumption, and cannot be popularized on a large scale, so it cannot be widely used.
