Description
Technical field
The present invention relates to a kind of gypsum and preparation method thereof, and in particular to one kind has ecological functions gypsum and its preparation side
Method.
Background technology
It is well known that environmental problem turns into the matter of severe problem, particularly living environment that human development must be faced
Amount increasingly obtains the concern of people.It is a large amount of in due to decorating indoors to use the poor quality containing harmful substances such as formaldehyde, toluene
Material, brings great harm to the physical and mental health of people, and the incidence of disease such as cancer is constantly raised, so constantly releasing healthy ring
The ecotecture ornament materials of guarantor is building material industry obligation one can't decline.
The content of the invention
The technical problems to be solved by the invention be to provide one kind can on one's own initiative, effectively purify indoor environment, it is to avoid have
Noxious material is detrimental to health, and a health, comfortable work and living environment can be built for people has ecological functions stone
Cream and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is：
The present invention's has ecological functions gypsum, is made up of the raw material of following weight：Land plaster, nanoscale dioxy
Change titanium 1.2-1.8%, Nano Silver 0.4-0.6%, water 60-70%, the Nano titanium dioxide, Nano Silver, the percentage of water
Using land plaster weight as radix.
Further, the preferred 1.4-1.6% of the Nano titanium dioxide, more preferably 1.5%.
Further, the preferred 0.45-0.55% of the Nano Silver, more preferably 0.5%.
Further, the preferred 62-68% of the water, more preferably 65%.
The Nano titanium dioxide is a kind of nontoxic, and catalytic activity is high, and oxidability is strong, corrosion-resistant good excellent light
Catalyst.
The Nano Silver is that particle diameter is accomplished nano level argent simple substance by one kind, puts it into carrier, and a kind of height is made
The bactericide of effect.
The water can be the domestic water without objectionable impurities, such as running water.
The preparation method with ecological functions gypsum of the present invention, comprises the following steps：
(1) first nanoscale TiO is weighed by preset blending ratio2, Nano Silver, water；
(2) material weighed is put into bucket and be stirred, obtain mixed solution；
(3) land plaster is weighed by preset blending ratio again, poured into the bucket equipped with mixed solution, stirred, obtain gypsum slurry；
(4) gained gypsum slurry is poured into mould mould, shakes, strikes off, rejecting clout, stood, is stripped, dried.
The mechanism of action of the additive of the present invention：
(1)TiO2The mechanism of action：TiO2High, the stable chemical performance with catalytic activity, oxidation-reduction quality is strong, most of
Organic pollution can be under benign environment in TiO2Surface permineralization is CO2And H2O, irradiates in the ultraviolet of certain wavelength
Under, TiO2Absorb luminous energy, the electronics (e of its out orbit-) will be excited and cross forbidden band and enter conduction band, while in original track
On leave a space (h+), this space has very strong oxidisability, can be by TiO2The hydrone of surrounding is oxidized to hydroxyl free
Base (.OH), and excite generation electronics (e-) there is very strong reducing power, by TiO2Neighbouring O2It is reduced into (.O2 -).Hydroxyl is certainly
By base (.OH) and (.O2 -) all it is the group with very Strong oxdiative ability, can be by TiO2Neighbouring organic matter or bacterium effectively divides
Solution, such as formaldehyde, toluene, so as to reach the effect of purification air.
(2) mechanism of action of Nano Silver：The haptoreaction of silver ion causes microorganism to have component damage or produces function
Obstacle.When micro silver ion reaches microbial cell film, because the latter is negatively charged, by Coulomb attraction, make both firm
Absorption, silver ion penetration cell wall enters intracellular, makes protein coagulating, destroys the activity of cell synzyme, cell loss division
Multiplication capacity and it is dead.Silver ion can also destroy microorganism electric transmission system, respiratory system and substance delivery system, and division is thin
Bacterium, the cell membrane of virus, can effectively kill 12 kinds of Gram-negative bacterias and 8 kinds of Gram-negative bacterias, Escherichia coli, golden yellow
The extremely sick bacterium such as coccus.Meanwhile, in the presence of ultraviolet, sodium rice silver and water or air effect, generation active oxygen O2 -And freedom
Base .OH, its redox, the active oxygen O when harmful bacteria is close to nanometer silver surface2 -With free radical .OH by attack bacteria
After birth, is killed.
The ecological functions added material system that the present invention is used uses the raw material that can be used on food additives and cosmetics,
Do not have to have admixed 5 Nano titanium dioxides, Nano Silver, pure water, shape in any toxic action, ecological series additive to human body
Into a kind of responsive to visible light type photocatalyst, it can just be worked under common illumination, even same under low-light occur light
Catalytic action, produces active oxygen and hydroxyl free radical, persistently induces a large amount of negative oxygen ions, to harmful in product itself and air
The harmful substance such as chemical substance, especially PARA FORMALDEHYDE PRILLS(91,95), toluene, ammonia and TVOC (volatile organic matter) has stronger degradation capability,
All also there is extremely strong killing ability to harmful bacteria simultaneously.
Gypsum hardenite used of the invention has natural microcellular structure, and with good respiratory function, itself can be preferable
Ground adjusts indoor temperature and humidity.It is sustainable to induce a large amount of negative oxygen ions, sustaining degradation harmful chemicals thing after the ecological additive of addition
Matter, sustained anti-microbial is mould proof, comprehensive decontamination room air, lifts IAQ, improves indoor environment, is really achieved green life
Effect of state.
Obtained by the present invention have ecological functions gypsum, can on one's own initiative, effectively purify indoor environment, it is to avoid Toxic
Matter is detrimental to health, and a health, comfortable work and living environment can be built for people.
