Description
Technical field
The invention belongs to building material field, specifically, the present invention relates to a kind of environment-friendly type diatomite composition and its
Using.
Background technology
Interior decoration usually requires to use a variety of finishing materials, easily produces formaldehyde, benzene class and other indoor organic gas
Material TVOC overlying pollutions, improve indoor environment, and reduction finishing pollution is paid attention to by increasing people.
Diatom ooze is a kind of interior decoration wall material using diatomite as primary raw material, is made up of pure natural inorganic material, green
Colour circle is protected, and itself is without any pollution, free from extraneous odour.The nucleus of diatom ooze is diatomite.Diatomite is with SiO2Based on, light weight is dredged
Pine, density is 1.9~2.3g/mL, and specific surface area is 40~65m2/g.Diatomite is special porous construction, and rule is fitly
The micropore quantity being arranged in circular or aciculiform, its unit area is thousands of times of activated carbon.The molecular grating that diatomite is protruded
Its unique function of structures shape, makes it have extremely strong physical absorption and ion-exchange performance, extensively should after finishing
For fields such as functional coating, medicine filter aid, food additives, core radiation adsorbents.
In existing diatom ooze formula system, except conventional auxiliary additive, nano titanium oxide can be added toward contact
As photocatalyst catalyst, absorption is decomposed in diatom ooze surface or the organic molecule of endoporus；Or antibiotic bactericide, suppress
Bacterial growth.Diatomite is the nucleus of diatom ooze, but diatomite available diatomaceous earth products mistake from exploiting to being purified to
Often over high-temperature roasting in journey, on the one hand cause its specific surface area reduction (only 20-30m2/ g), under causing adsorption capacity significantly
Drop；On the other hand, high-temperature roasting causes the hydroxyl of diatomite microcosmic surface adjacent position to occur chemical dehydration, forms Si-O-
Si structures so that diatomite the adsorbed hydroxyl content is substantially reduced, thus also result in adsorption strength and adsorption capacity and and its
Corresponding reduction can also occur for the bond strength of its auxiliary material, and moisture absorption and damping ability are equally reduced.
