The invention discloses a composite antibacterial anion air
cleanser and a preparation method thereof. The air
cleanser comprises the following raw materials by weight percent: 0.5-30 % of colorless and transparent anion
crystal /
powder, 0.5-2 % of photocatalyst
powder, 1-10 % of a transparent nano silver solution, 1-15 % of food-grade
ethanol, 0.1-5 % of natural
plant essential oil and 20-50 % of deionized water. The air
cleanser provided by the invention can rapidly decompose
formaldehyde,
benzene,
ammonia and other harmful gases in spaces in a few minutes, with a cleansing rate of more than 98 %, and is rapidly and durably antibacterial and antivirus; furthermore, the air cleanser does not contain
toxic chemical compositions, and is free of any side effects on the body and secondary
pollution. According to the invention, the air cleanser decomposes
odor molecules through anion and
photocatalytic decomposition factors to remove odors, and can durably release a lot of negative
oxygen ions, wherein the negative
oxygen ions are known as "air
vitamin" and are beneficial for human's physical and
mental health, so that the air cleanser provided by the invention has relatively good health care function.
