Description
Technical field
The present invention relates to air disinfection taste removal technical fields, specifically, being related to a kind of eliminating smell agent for having both sterilizing function
And preparation method thereof.
Background technique
As the mark in third pollution period, " room air pollution " has become the topic that people increasingly pay close attention to, people
The average most of time daily is to spend indoors, and indoor air quality directly affects the health of people.There is tune
Look into display, usually 2-3 times more serious than outdoor air pollution of room air pollution degree, in some cases even up to 100 times
More than, so, it solves current increasingly prominent air pollution problem inside rooms and has been very urgent.
Currently, various finishing materials, carpet, furniture, fabrics, plate etc. can volatilize many after the completion of house decoration
Noxious pollutant mainly includes formaldehyde, benzene homologues and other volatile organic matters (VOCs), and with the bacterial virus of floating
Deng causing indoor to have very unpleasant peculiar smell.
With titanium dioxide (TiO2) be widely used in coating and finishing improvement for the photocatalyst of representative.It is demonstrated experimentally that
Photocatalyst is really effective in terms of pollutant elimination, not will cause secondary pollution in theory.But photocatalyst product
Maximum weakness is that must have sunlight or ultraviolet irradiation, and every square metre of intensity of illumination for reaching 2W could sufficiently start light
The pollution treatment ability of catalyst, general indoor environment cannot reach starting effect well.Other air-deodouring agents in the market are more
With odor type cover or the method for passive adsorption, smell cannot be effectively absorbed or remove, and cannot reach lasting there are instantaneity
Effect.
Natural botanical extraction liquid can eliminate rapidly peculiar smell rather than temporary covering smell, they contain multiple total mostly
Yoke double bond systems provide the ability of electronics pair with stronger, increase the reactivity of odor molecules in this way.In addition, plant
Effective ingredient sequiterpene polyester class, alcohol compound in extracting solution have stronger bioactivity, can effectively attack air
In smell component and germ, the chemical combination key in odor molecules is weakened, so that the unstability of odor molecules increases, at this time
Odor molecules make it be easy to be chemically reacted with other molecules because of above two reason.However simple plant extraction liquid
It is volatile, so that taste removal effect is difficult to persistently.
