Description
Technical field
The present invention relates to building coating technical fields, and in particular to a kind of no compound diatom ooze of rubber powder and preparation method thereof.
Background technique
Current decorative material for wall surface many places are in single painting aesthetic effect, such as dry powder, powder of lacquer putty for use on, wallpaper, plaque
Wall body decoration and fibrous structure product.Dry powder, powder of lacquer putty for use on, which belong to, fills and leads up whitening；And the fibrous structure material wallpaper,
Plaque in pasting use process all there is it is inflammable, mouldy, fall off the problems such as and the toxic object such as methanol, heavy metal, ammonia
The risk of exceeding criterion of matter.
Traditional building coating is due to using the binders such as rubber powder that can give out many kinds of and complicated organic matter
And be difficult to completely remove, it be easy to cause secondary pollution；Using the organic matter that diffuses in active carbon removal environment or other it is harmful at
Though the efficiency divided is high, because its adsorbance is limited, it also be easy to cause secondary pollution.In contrast, nano-titanium dioxide is then one
Kind efficient photocatalyst class material, with good photocatalytic activity, can fast decoupled organic matter, be irradiated in ultraviolet light
The stronger hydroxyl free radical group of oxidability is generated in journey, and there are many merits such as antibacterial, sterilization, deodorization, automatically cleaning, be considered as
The environmentally friendly class product of great potential.
Currently, diatom ooze coating is because of its asepsis environment-protecting and has good sense of touch, it is widely used in indoor decoration
Engineering becomes the hot spot of current house decorative material.Diatom ooze (Diatom mud) is one kind using diatomite as main raw material(s)
Novel wall ornament materials.Diatom is a kind of to live in ocean, the algae in lake.These live in the water before millions of years
Capture trip class biology forms natural materials by prolonged deposition --- and diatomite, diatomite main mineral constituent are albumen
Stone and its mutation are rich in several mineral materials, and the light and soft exquisiteness of quality is porous, are suitable for indoor coating process and use, and construction applies
Smear, during pattern-making etc. can any moulding, and the formaldehyde in air can be adsorbed and adjust indoor temperature, received
The favor of people.But current diatom ooze coating needs there is also high production cost, difficulties in dispersion, easy the defects of reuniting into one
The improvement of step optimizes.
Therefore, it needs the formula to existing diatom ooze to optimize at present, to remove negative effect caused by rubber powder, and makes
The harmful substances such as benzene in simultaneously decontamination chamber can be adsorbed by obtaining diatom ooze coating；Solve that existing diatom ooze dispersion performance is low to ask simultaneously
Topic reduces production cost, and improves coating property.
Summary of the invention
The purpose of the present invention is to provide a kind of no compound diatom oozes of rubber powder, make without using commercial synthesis rubber powder or lotion
For bonding agent, so as to avoid in existing coating since industrial rubber powder or lotion cause asking for secondary pollution as binder
Topic；Safety and environmental protection, while dispersion performance is good；The pernicious gases such as the formaldehyde in air can not only be adsorbed, additionally it is possible to it is decomposed,
To fundamentally solve room air pollution；In addition its production cost reduces, and weatherability is good.
