Description

A kind of sepiolite with coordination function/diatomite basic ring protects indoor wall material
Technical field
The invention discloses a kind of sepiolite with coordination function/diatomite basic ring to protect indoor wall material, belongs to indoor Building material technical field.
Background technology
With the improvement of people ' s living standards and health environment-friendly consciousness enhancing, indoor environmental quality be increasingly subject to weight Depending on.Indoors during wall surfacing, people select wall material product in addition to paying close attention to beautiful decoration, also begin to focus on the nothing of material Evilization and feature, wherein the natural minerals basic ring with multiple functions, which protects indoor wall material, increasingly becomes everybody first choice. At present, the function of the indoor wall material of natural minerals basic ring guarantor focuses primarily upon damping, air purification, antibacterial three zones, while Subsidiary some other functions, such as：Fire protection flame retarding, sound-absorbing and noise-decreasing, insulation, go to eliminate the unusual smell.
Humidity conditioning function is based primarily upon the strong absorption property of natural porous mineral.Due to diatomite, zeolite, sepiolite, bumps The natural porous such as rod stone mineral have flourishing pore passage structure and big specific surface area, and hydrone is acted on adsorption and desorption, Institute so as to automatic adjustment indoor environment humidity, i.e., can be wet to reduce indoor environment with moisture absorption when indoor environment humidity is higher Degree, can be with moisture releasing, to lift indoor environment humidity when indoor humidity is relatively low.As porous mineral humidity adjusting material, diatomite and Zeolite has three-dimensional open-framework, belongs to macropore or mesoporous；Sepiolite and attapulgite are one-dimensional columns or filamentary structure, are belonged to In mesoporous or micropore.The humidity of single porous mineral is extremely limited, but by by different pore passage structures or different pore size The porous mineral of size is combined by a certain percentage, and the humidity of obtained combined material can significantly improve.In addition need It should be noted that since the characteristic of humidity adjusting material makes the relative humidity on its surface generally higher, and moist environment is easily led Cause various bacteriums, mould its surface grow and amount reproduction, in order to avoid this rough sledding, preferably add in humidity adjusting material Add a certain amount of anti-biotic material.
Air-cleaning function is based primarily upon catalysis material nano-TiO2.Nano-TiO2In ultraviolet light or solar irradiation condition The photo-generate electron-hole pair of high activity can be produced down, and light induced electron can be with nano-TiO2The O of particle surface2Generation reduction is anti- H and should be generated2O2And active oxygen, photohole and nano-TiO2The H of particle surface2O and hydroxyl occur oxidation reaction and generate hydroxyl Base free radical.H2O2, active oxygen and hydroxyl radical free radical can thoroughly divide the multiple indoor such as formaldehyde, toluene air organic pollutants Solve as CO2And H2The inorganic molecules such as O.In addition, H2O2The cell membrane of bacterium, mould can also be destroyed with active oxygen, is inhibited bacteria Activity, and the endotoxin produced after decomposing bacteria death can also catch the planktonic bacteria killed except in air, so nanometer TiO2Also there are certain antibacterial functions at the same time.
Antibacterial functions are based primarily upon inorganic antiseptic nano-ZnO.Nano-ZnO can discharge zinc ion, and zinc ion penetrates carefully After birth enters cell interior, is destroyed intracellular protein denaturation and physiological activity, so as to cause cell death.Moreover, After thalline is killed, zinc ion can be contacted and killed again other thalline with separate out, so nano-ZnO has long-acting kill Bacterium ability.In addition, nano-ZnO is also a kind of catalysis material, with above-mentioned nano-TiO2Photocatalysis principle it is identical, in ultraviolet light Or under solar irradiation, it is same that photocatalytic redox reaction, the H of generation occurs2O2Bacterium can also be killed with active oxygen, is generated Various active group can also degrade multiple indoor air organic pollutants.
At present, the main preparation methods of the indoor wall material of environmental protection are：By natural porous mineral powder, nano-function powder, phase The filler powder and auxiliary agent answered carry out dry powder and are stirred.Wherein, common nano-function powder includes nano-TiO2Powder and Nano ZnO powder.Since the specific surface area of these nano-function powders is very big and surface free energy is high, in the unstable shape of energy State, is easy to secondary agglomeration into bulky grain, so as to influence the normal performance of its corresponding function.Process is stirred in dry powder, by In stirring dynamics and depth it is limited, nano-function powder it is scattered relatively difficult, there are substantial amounts of agglomeration, this is not only reduced The feature of environmentally friendly indoor wall material, but also be the serious waste to expensive nano-function powder.Generally for up to Effect to a certain extent, generally requires to add the nano-function powder of excess, causes product cost significantly to increase.Separately Outside, a phenomenon that should be noted is, during environmentally friendly indoor wall material use, since nano-function powder is no and it His bulky grain component strong bonded, the scraping and wind-force effect, nano-function powder for being subject to external force are easy to split away off, and Nano-powder particle is superfine to be difficult to settle, and is floated for a long time in atmosphere, if can be produced to health in suction human body certain Harm.
The content of the invention
For above-mentioned the deficiencies in the prior art, the present invention provides a kind of sepiolite/silicon with coordination function Diatomaceous earth basic ring protects indoor wall material, and nano-TiO is prepared using hydrolysis methods2, nano-ZnO and at the same time by it firmly, it is uniform negative It is loaded on porous mineral diatomite and sepiolite, has obtained ZnO/ TiO2/ sepiolite/diatomite composite material, then will be compound Functional material is stirred with corresponding filler, auxiliary agent is mixed with environmentally friendly indoor wall material, effectively solves nano-TiO2, receive Rice ZnO is in environmentally friendly indoor wall material the problem of bad dispersibility.Meanwhile the present invention has taken into full account environmentally friendly room in the selection of component Mutually coordinated between inner wall material damping, antibacterial and air-cleaning function and mutually promote, sepiolite and diatomaceous combination carry Humidity, nano-TiO are risen2Combination with nano-ZnO improves photocatalysis performance, nano-TiO2, nano-ZnO antibacterial work( With the antibacterial of sierozem power filler mutual cooperation, sepiolite, diatomaceous absorption property and nano-TiO can be acted on except mould2, nanometer The mutual cooperation of ZnO photocatalytic degradation air organic pollutants functions.
The technical solution adopted by the present invention：A kind of sepiolite with coordination function/diatomite basic ring protects indoor wall material, main To include composite functional material, filler and auxiliary agent, the composite functional material is ZnO/TiO2/ sepiolite/composite diatomite material Material, is prepared using following processing step：（1）By quality proportioning diatomite 20-40%, sepiolite 20-40%, TiOSO4Powder 15- 20%、ZnSO4Powder 15-20% prepares mixed powder, by liquid-solid ratio 40-50:1 adds water into mixed powder and stirs evenly；（2） The weak aqua ammonia that mass concentration 10% is slowly dropped into solution adjusts pH value of solution and quickly stirs, until the pH value of solution is 5-7； （3）Obtained sediment is filtered and is washed with water, is then dried；（4）Product is at 450-550 DEG C after drying 2-3h is calcined, that is, obtains the composite functional material；
