Description
Technical field
The present invention relates to building material technical field, and in particular to a kind of Multifunctional diatom ooze wall material.
Background technology
It is well known that the construction after household blank is completed in building household field to wall is particularly important, thus have
Selection to wall material.Traditional home decoration wall material is broadly divided into paint class, the major class of wallpaper two, and both wall materials are in the process used
In, in the presence of different degrees of VOC emission, especially formaldehyde, serious threat health.It is with the development of the social economy, existing
Moderns require finishing more and more higher, and people propose more while high-grade decorative effect is pursued to the feature of environmental protection of wall material
High requirement, in order to meet the needs of people, some, which occurs, in the market can adsorb and purify the wall of harmful substance in air
Material, especially diatom ooze wall material, turn into the typical case of environmental protection building material instantly, are widely used in recent years, and diatom ooze is
Formed by the remains sedimentation of unicellular water plant diatom, form several nanometers to more than ten nanometers of micropore, its ultramicropore is than wood
Charcoal it is more go out 5000 to 6000 times, the formaldehyde to dissociate in air, benzene, harmful substance and the hydrone such as ammonia can be adsorbed, had
Good chemically and physically stability, has broader development prospect compared to traditional indoor set material.In the market
There is substantial amounts of diatom ooze wall material, with the addition of the tackifier such as latex powder, pulverized limestone mostly, these materials are often with diatomite etc.
Material reaction is bonded together, plug diatomaceous hole, in order to improve intensity, hygroscopicity with the addition of bentonite, kaolin,
The materials such as attapulgite, but diatomaceous adsorptivity is not improved significantly.
The content of the invention
It is an object of the invention to provide a kind of multi-functional diatom ooze wall material, for solving existing diatom ooze wall material hole
Rate is low, the problems such as adsorptivity difference.
To achieve the above object, the present invention from the zeolite of calcining by being used as auxiliary material, by chemical method to diatom ooze
The raw material of wall material carries out soaking and washing, increases porosity, improves absorption property.Realized especially by following technical scheme：
A kind of Multifunctional diatom ooze wall material, by weight including following components：

Further, the anticracking fiber is polyester fiber or polypropylene fibre, and length is 1~5mm；
Further, the plant cellulose is methylcellulose, hydroxymethyl cellulose, hydroxypropyl cellulose or ethoxy
One or more in cellulose；
Further, the thickening powder is glutinous rice rubber powder；
Further, the photocatalyst is mesoporous molecular sieve carried titanium dioxide and zinc oxide, and particle diameter is 200~500 mesh；
A kind of preparation method of Multifunctional diatom ooze wall material, comprises the following steps：
(1) diatomite, calcined zeolite powder, sepiolite powder and quartz sand are weighed by weight ratio, are added to concentration as 20
In~30% acid soak, stirring immersion 12~24 hours, wet-milling is filtered to obtain；
(2) after wet-milling obtained by step (1) being carried out into clear water washing, mixed-powder is obtained after drying, grinding；
(3) anticracking fiber, plant cellulose, photocatalyst and thickening powder are weighed by weight ratio is added to step (2) institute
Obtain in mixed-powder, be put into agitator and be uniformly mixed.
Further, the acid soak is one kind in hydrochloric acid, sulfuric acid or nitric acid.
The inventive method has the following advantages that：
1st, a kind of Multifunctional diatom ooze wall material of the present invention, calcined zeolite ash, sepiolite powder, quartz sand are added in diatomite
For auxiliary material, zeolite powder greatly increases porosity and specific surface area by calcining, and quartz sand improves the matter of diatom ooze wall material
Sense and intensity, by adding these auxiliary materials, not only increase the porosity of diatom ooze wall material, while harmful substance is adsorbed,
Can also adsorption moisture, reach the purpose for automatically adjusting indoor humidity.
2nd, a kind of Multifunctional diatom ooze wall material of the present invention, anticracking fiber and plant cellulose are added, improves the machine of wall material
Tool intensity, metope is cracked after preventing construction, using glutinous rice tackifier, will not be released while diatom ooze wall material viscosity is increased
Harmful substance is put, it is green.
3rd, the present invention removes diatomite, zeolite powder, quartz sand, sepiolite powder table by carrying out pickling processes to raw material
Attachment in face and hole, improve the porosity and specific surface area of diatom ooze wall material so that diatom ooze wall material formaldehyde adsorption,
The ability of the harmful substances such as VOC greatly improves.
4th, mesoporous molecular sieve carried titanium dioxide and zinc oxide are with the addition of in the present invention, substantially increases titanium dioxide and oxygen
Change the photocatalytic activity of zinc, formaldehyde, toluene etc. effectively can be resolved into CO2And H2O, formaldehyde, first are thoroughly removed so as to reach
The purpose of the harmful substances such as benzene, secondary pollution will not be brought, simultaneous oxidation zinc can also destroy the cell membrane of bacterium, play sterilization
Effect.
