Description

A kind of meerschaum/kieselguhr basic ring with coordination function protects chamber interior walls material

Technical field

The invention discloses a kind of meerschaum/kieselguhr basic ring with coordination function and protect chamber interior walls material, belong to indoor Building material technical field.

Background technology

Along with raising and the enhancing of health environment-friendly consciousness of people's living standard, indoor environmental quality is increasingly by weight Depending on.In indoor wall fitment process, 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 functional, wherein has the natural minerals basic ring of several functions and protects chamber interior walls material and increasingly become everybody first-selection. At present, natural minerals basic ring is protected the function of chamber interior walls material and is focused primarily upon damping, air cleaning, antibacterial three zones, the most also More subsidiary 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 kieselguhr, zeolite, meerschaum, concavo-convex The natural porous mineral such as rod stone have the pore passage structure of prosperity and big specific surface area, have adsorption and desorption effect to hydrone, It is possible to be automatically adjusted indoor environment humidity, i.e. can be wetter to reduce indoor environment with moisture absorption when indoor environment humidity is higher Degree, can be with moisture releasing when indoor humidity is relatively low, to promote indoor environment humidity.As porous mineral humidity adjusting material, kieselguhr and Zeolite has three-dimensional open-framework, belongs to macropore or mesopore；Meerschaum and attapulgite are one-dimensional column or filamentary structure, belong to In mesopore or micropore.The humidity of single porous mineral is extremely limited, but by by difference pore passage structure or different pore size The porous mineral of size is combined by a certain percentage, and the humidity of the combined material obtained can significantly improve.Additionally need It should be noted that owing to the characteristic of humidity adjusting material makes the relative humidity on its surface the highest, and the environment of humidity is easily led Cause various antibacterial, mycete grows and amount reproduction on its surface, in order to avoid this rough sledding, preferably adds 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 Under can produce highly active photo-generate electron-hole pair, light induced electron can be with nano-TiO₂The O of particle surface₂Occur reduction anti- And H should be generated₂O₂And active oxygen, photohole and nano-TiO₂The H of particle surface₂O and hydroxyl generation oxidation reaction also generate hydroxyl Base free radical.H₂O₂, the multiple indoor air organic pollutants such as formaldehyde, toluene can thoroughly divide by active oxygen and hydroxyl radical free radical Solve as CO₂And H₂The inorganic molecules such as O.Additionally, H₂O₂With the cell membrane that active oxygen can also destroy antibacterial, mycete, suppress antibacterial Activity, and the endotoxin produced after decomposing bacteria death, it is also possible to catch and kill except the planktonic bacteria in air, so nanometer TiO₂Also there is certain antibacterial functions simultaneously.

Antibacterial functions is based primarily upon inorganic antiseptic nano-ZnO.Nano-ZnO can discharge zinc ion, and zinc ion penetrates carefully After birth enters cell interior, makes intracellular protein denaturation and physiologically active be destroyed, thus causes cell death.And, After thalline is killed, zinc ion can dissociate out and again contact and kill other thalline, so nano-ZnO has long-acting killing Bacterium ability.It addition, nano-ZnO is also a kind of catalysis material, with above-mentioned nano-TiO₂Photocatalysis principle identical, at ultraviolet light Or under solar irradiation, same generation photocatalytic redox reaction, the H of generation₂O₂Antibacterial can also be killed with active oxygen, generate Various active group can also degrade multiple indoor air organic pollutants.

At present, the main preparation methods of environmental protection chamber interior walls material is: by natural porous mineral powder, nano-function powder, phase The filler powder body answered and auxiliary agent carry out dry powder stirring mixing.Wherein, common nano-function powder includes nano-TiO₂Powder body and Nano ZnO powder.Owing to the specific surface area of these nano-function powders is very big and surface free energy is high, it is in energy instability shape State, as easy as rolling off a log secondary agglomeration becomes bulky grain, thus affects the normal performance of its corresponding function.Mixed process is stirred at dry powder, by Limited in stirring dynamics and the degree of depth, the dispersion of nano-function powder is relatively difficult, there is substantial amounts of agglomeration, and this not only reduces Environmental protection chamber interior walls material functional, but also be the serious waste to expensive nano-function powder.Generally for reaching Effect to a certain extent, generally requires the nano-function powder adding excess, causes product cost significantly to increase.Separately Outward, also a phenomenon that should be noted that is, during environmental protection chamber interior walls material uses, owing to nano-function powder does not has and it His bulky grain component strong bonded, by scraping and the wind-force effect of external force, nano-function powder is as easy as rolling off a log to split away off, and Superfine being difficult to settles nano-powder granule, the most floating in atmosphere, if sucked in human body, health can be produced certain Harm.

Summary of the invention

For above-mentioned the deficiencies in the prior art, the invention provides a kind of meerschaum/silicon with coordination function Diatomaceous earth basic ring protects chamber interior walls material, uses hydrolysis methods to prepare nano-TiO₂, nano-ZnO bear simultaneously by it firmly, uniformly It is loaded on porous mineral kieselguhr and meerschaum, has obtained ZnO/ TiO₂/ meerschaum/diatomite composite material, then will be compound Functional material is stirred with corresponding filler, auxiliary agent being mixed with environmental protection chamber interior walls material, effectively solves nano-TiO₂, receive Rice ZnO problem of bad dispersibility in environmental protection chamber interior walls material.Meanwhile, the present invention has taken into full account environmental protection room choosing of component Mutually coordinated between inner wall material damping, antibacterial and air-cleaning function and mutually promoting, meerschaum and diatomaceous combination carry Humidity, nano-TiO are risen₂Combination with nano-ZnO improves photocatalysis performance, nano-TiO₂, the antibacterial merit of nano-ZnO Can and the antibacterial of sierozem power filler cooperate except mould effect, meerschaum, diatomaceous absorption property and nano-TiO₂, nanometer Cooperating of ZnO photocatalytic degradation air organic pollutants function.

The technical solution used in the present invention: a kind of meerschaum/kieselguhr basic ring with coordination function protects chamber interior walls material, main Composite functional material to be included, filler and auxiliary agent, described composite functional material is ZnO/TiO₂/ meerschaum/composite diatomite material Material, uses following processing step to prepare: (1) is by quality proportioning kieselguhr 20-40%, meerschaum 20-40%, TiOSO₄Powder 15- 20%、ZnSO₄Powder 15-20% prepares mixed powder, adds water by liquid-solid ratio 40-50:1 and stir in mixed powder；(2) In solution, it is slowly dropped into the weak ammonia regulation pH value of solution of mass concentration 10% and quickly stirs, until the pH value of solution is 5-7； (3) precipitate obtained is filtered and washes with water, then dry；(4) afterproduct will be dried at 450-550 DEG C Calcining 2-3h, i.e. obtains described composite functional material；
