Description
Technical Field
The invention belongs to the technical field of deodorant, and particularly relates to a high-efficiency deodorant and a preparation method thereof.
Background
Air is the most important supply of most species on earth, and air quality has a direct effect on human health; due to the lack of air exchange, people have increased time in closed spaces such as homes, schools, offices, vehicles, hospitals, and the like, air pollutants are particularly alarming, especially in view of their threat to vulnerable groups such as children, elderly people, and patients.
At present, the traditional deodorant is one of common deodorizing measures and is used for adjusting indoor air quality and protecting people from health hazards such as particulate matters, biological aerosol, volatile organic compounds and the like; most of traditional deodorant in the market utilizes physical barrier and adhesion effect to capture particles, so that the air standard of the high-efficiency particles is met; however, these conventional deodorants have obvious disadvantages including high air resistance and limited ability to inhibit harmful microorganisms, and the formation of harmful byproducts in the presence of other air pollutants, resulting in secondary air pollution; with the efforts of researchers, some deodorant materials containing photocatalytic effects are presented, but these materials require ultraviolet light excitation when active, which is unfavorable for indoor use where people live for a long time, and sterilization efficiency is low and continuous effect is poor when sunlight is a light source.
Therefore, it is highly desirable to develop an integrated high-efficiency deodorant that can remove particulates, kill bacteria, and also exert a sterilizing effect under visible light conditions.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a high-efficiency deodorant and a preparation method thereof, which effectively solve the problems that the existing deodorant has limited inhibition capability to harmful microorganisms, is easy to cause secondary air pollution, needs ultraviolet excitation and the like; the invention adopts a photocatalysis sterilization polymer, is prepared by 2, 4-dihydroxyl-1, 3, 5-trimellitic aldehyde and 6,6 '-dimethyl-2, 2' -bipyridine through a kebrain venturi condensation reaction, has the characteristics of good porosity, chemical structure diversity, adjustability and the like, and can be used as an adsorbent and a catalyst for controlling air pollution; under the irradiation of visible light, the generated active oxygen can be used as a strong oxidant to kill harmful microorganisms, has good sterilization activity and removes peculiar smell; meanwhile, the preparation method of the efficient deodorant provided by the invention is simple and convenient, and can realize large-scale production.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
the invention provides a high-efficiency deodorant which comprises the following components in parts by weight: 50-100 parts of photocatalysis sterilization polymer, 1-10 parts of sodium dodecyl benzene sulfonate, 1-10 parts of polyethylene glycol, 1-5 parts of adhesive, 0.5-5 parts of lubricant and the balance of water.
