Description
Technical field
The present invention relates to a kind of high molecular material, especially a kind of air clearing product of high molecular reactive oxygen decomposition technique
And preparation method thereof.
Background technique
With flourishing for China's real estate cause, office building, fitting up for home dwelling become the essential of people.But
In recent years because the formaldehyde, benzene, volatile organic matter (TVOC) pollution problem of finishing material initiation become increasingly conspicuous.Formaldehyde is a kind of
There is the health of human body and seriously endanger in the colourless gas with intense irritation smell, influence the alimentary canal of people, respiratory tract and
Skin the problems such as so as to cause carcinogenic, abnormal property, is classified as a kind of carcinogen by the World Health Organization.Therefore, it develops a kind of green
Color, environmental protection, the air clearing product for efficiently removing formaldehyde, benzene, TVOC pollutant, have become in environmental friendly material field and compel
It is essential and asks.
Photocatalyst technology is to release most one of product technologies currently on the market.Main method mentions active carbon, tealeaves
The load photocatalyst material such as the organic materials such as object, plant extraction liquid, biomaterial, doping and modified biomaterial is taken to realize net
Change the technology of air.Du Chunhua [Du Chunhua, a kind of high-efficiency formaldehyde scavenging agent and preparation method thereof, publication number CN
107583464A] nano-titanium dioxide is supported on natural plant extracts, hypersober is added, realizes the clear of plate surface
Except formaldehyde purpose.Adsorbent material purification air technique has the drawback that: the materials such as natural minerals, active carbon are easy to appear absorption
Pollutant saturation, to dispel pollutant persistency ability inadequate.Xiao Jiansheng [Xiao Jiansheng etc., a kind of novel environment friendly nano photo-catalytic first
Aldehyde scavenger, publication number CN106731791A] a kind of novel environment friendly nano photo-catalytic formaldehyde scavenger is disclosed, select load platinum to receive
The sharp peptide mine type titanium dioxide of rice, silk peptide based surfactants, capturing agent, bleeding agent etc. realize the net of formaldehyde under visible light
Change.In a kind of Ding Yuqin [Ding Yuqin, preparation method of formaldehyde scavenger, publication number CN 107638788A] extraction plant, tealeaves
Effective component, and masking net can be formed on the surface of medium by salt water itself, it adsorbs and removes the free alcohol in these media
Equal volatile substances, are quickly penetrated into its effective component in substance containing formaldehyde using bleeding agent, ethereal oil, and pass through catalyst
Catalysis formaldehyde is reacted with oxygen in air, reaches elimination effect.[Xie Biqing, a kind of macromolecule formaldehyde scavenger are public by Xie Biqing
The number of opening CN 108066931] it is prepared into using the high molecular polymer, aminated compounds, plant extraction liquid etc. of carbodiimide group
The formaldehyde scavenger arrived purifies the formaldehyde in air using the reactivity of amine groups and formaldehyde.
Currently, existing photocatalyst and relevant technology have the disadvantage in that (1) nanometer particle is easy to reunite；(2) it is difficult
Uniform, lasting effective nanometer layer is formed on surfaces such as plate, metopes；(3) pollutant sufficiently quickly removed in air needs
Sufficiently large specific surface area material support；(4) unmodified nano photo-catalytic can only realize photocatalysis under ultraviolet light,
Cannot under daily visible light wave-length coverage energy level transition, be extremely difficult to formaldehyde in effective or lasting removal air, benzene,
The purifying property and persistence of the noxious pollutants such as ammonia, other volatile organic matters, mould purify；(5) nano photo-catalytic layer holds
It is influenced vulnerable to external dust, impurity etc., failure easy to fall off, air quality easily has a rebound phenomenon.
Major defect existing for the purification products of classifications such as existing chemical reaction spray is when spraying one section on the surface of the material
Between after have a rebound phenomenon, or even easily cause secondary pollution；It is main existing for the purification product of the classifications such as existing plant extraction liquid
The disadvantage is that: effect is slow, and elimination efficiency is not high, more single for the pollutant of removal, and some products even only play covering gas
The effect of taste.
Up to the present, it yet there are no the document report in relation to the air clearing product using high molecular reactive oxygen decomposition technique
Road.
