Description
Technical field
The present invention relates to the technical fields of purifying formaldehyde, disclose a kind of special diatom having the interior purifying formaldehyde for turning light
Mud and preparation method.
Background technology
With the improvement of living standards, how the use of a large amount of ornament materials, furniture appliance, lead to a large amount of chemicals appearance
Interior, many poisonous and hazardous substances are stealthily threaten the health of human body, and room air pollution, which has become, endangers the mankind
" the stealthy killer " of health.Therefore, Techniques for Indoor Air Purification is very urgent.Currently used indoor air purification skill
Art has:Absorption method, filtration method, photocatalytic oxidation, anion method, Ozone etc..
Absorption method be absorption method be using harmful components in certain substances for having an adsorption capacity i.e. adsorbent absorption air from
And reach the method for eliminating noxious pollutant purpose, be the most common purification techniques of current removal indoor volatile organic compounds it
One.Conventional using activated carbon adsorption at present, in recent years, its distinctive adsorptivity due to diatomite, diatom ooze is as indoor
Building, ornament materials, prepare diatomite paint, in order to solve kieselguhr adsorption saturability usually by way of directly mixing
The problem of, it is usually added into photochemical catalyst, realizes constant absorption and the decomposition of PARA FORMALDEHYDE PRILLS(91,95) gas.
In photocatalysis technology, nano titanium dioxide photocatalyst is a kind of tool development potentiality and obtains the light studied extensively
Catalyst, but it is limited by energy gap, limitation in practical applications and operation difficulty.And carbonitride is as a kind of
Non-metal semiconductor materials, energy gap is small, and photoresponse wave-length coverage is wide, has photocatalysis, but energy under visible light
The wave band enough utilized is still relatively narrow, the absorption decomposition rate of PARA FORMALDEHYDE PRILLS(91,95) relatively it is slow therefore, absorption method is combined with photocatalytic method
In development and application, the efficiency of light energy utilization for improving photochemical catalyst and the blockage of the micro orifice for preventing sorbing material are main research topics.
Chinese invention patent application number 201410557051.4 discloses a kind of diatom ooze decoration material for purifying formaldehyde
Material and preparation method thereof.Specifically, the diatom ooze ornament materials of the invention is made of following component as mass fraction:Essence
10.0 ~ 30.0 parts of diatomite processed;20.0 ~ 50.0 parts of powder stuffing;2.0 ~ 5.0 parts of re-dispersible glue powder;Gel rubber material 20.0 ~
40.0 parts;0.5 ~ 1.0 part of decentralized medium;3.0 ~ 8.0 parts of nano-titanium dioxide;1.0 ~ 4.0 parts of modifying agent;Anti-crack fiber 3.0 ~
5.0 part;20 ~ 80 parts of water.The diatom ooze ornament materials of the invention can be effectively increased purifying formaldehyde efficiency and significantly improve purification and hold
Long property, avoids physical absorption from losing the drawbacks such as adsorption effect because of saturation, can accelerate purification speed.In addition, the diatom of the invention
Mud ornament materials also has good thixotropy, suitable for moulding, while meeting the technological requirements such as mechanically spraying, brushing and roller coating,
The beneficial properties such as it is provided simultaneously with water-fast, alkaline-resisting, not dusting, do not crack..
Chinese invention patent application number 201610063507.0 discloses a kind of photocatalyst diatom ooze high-strength light plate, by
The photocatalyst layer of substrate and coating on the surface of the substrate is constituted;The ingredient and mass percent of substrate are as follows:Three-level diatomaceous earth, raw stone
The ingredient of ash, cement, reinforcing fiber, photocatalyst layer is as follows:Graphite phase carbon nitride, surfactant, adhesive, surplus are water;
Reinforcing fiber is the wood pulp of plant fiber, careless paddle, one kind of the glass fibre of chemical fibre or arbitrarily than a variety of.The light of the invention
Catalyst diatom ooze high-strength light plate itself can purify air without any pollution, and purifying formaldehyde performance reaches 92.5%;Formaldehyde is net
Change effect persistence and reaches 90%.
According to above-mentioned, the diatom ooze adsorbance in existing scheme for air purification is limited, and adsorption efficiency is low, and light is being added
When the pernicious gases constant absorption such as catalyst PARA FORMALDEHYDE PRILLS(91,95) decomposes, the micropore translucency on diatom ooze surface is poor, the luminous energy profit of catalyst
It is poor with rate, it can not especially solve the problems, such as that carbonitride light-use wave band is relatively narrow, cause photocatalytic degradation efficiency low, air is net
Change effect is poor, and the present invention proposes a kind of special diatom ooze and preparation method having the interior purifying formaldehyde for turning light, can effectively solve
Certainly above-mentioned technical problem.
Invention content
Low for air purification diatom ooze adsorption efficiency using wider at present, adsorbance is limited, traditional and photocatalysis
Technical method there are intensities of illumination poor, the catalyst efficiency of light energy utilization that agent combines, the catalytic degradation efficiency and effect of PARA FORMALDEHYDE PRILLS(91,95) are poor
The problems such as.
