Description
Technical field
Prepared the present invention relates to a kind of preparation method of aqueous inorganic paint and with aqueous inorganic paint inorganic
The method of coating.
Background technology
Relative to the currently building coating just based on the widely applied organic matter（Emulsion paint etc.）For, it has as follows
Advantage：1st, petrifaction：Inorganic coating with the petrifaction of mineral substrate, can form the silicic acid rock of a kind of waterproof and acid-proof,
So as to as natural stone；2nd, noninflammability：Inorganic coating has the characteristic of inorganic matter, its heat-resisting property is especially good, not only
It will not burn at a high temperature of 1200 DEG C, but also it is fire-retardant；3rd, gas permeability：Inorganic coating has the breathing of water proofing property and height
Power, makes the moisture of masonry inside freely outwards evaporate；There is the filtration of alkaloid substance at the same time, can prevent coating from playing gas
Bubble, produce thermal spalling and play scale and after peeling off and constructing by alkali pollution the shortcomings of；4 sterile and moss growths：Sterile and moss
Growing inorganic coating has the characteristic of alkali（PH value is more than 10.5）Mushroom and bryophyte spores, and its gas permeability can be killed（It is similar
Human skin water cannot so that sweat can eject）Building can be made to keep drying；Therefore mould inhibitor or anti-is needed not rely on
Rotten agent is grown to resist mould and moss, reaches natural moisture-proof, mould proof effect；5 painting colors never fade：Inorganic coating because
Characteristic with inorganic matter, and handled by special oxidation modification, it can entirely prevent the radiation of sub- shape, its color tool
There is the superpower weatherability of uniqueness；6 feature of environmental protection：Inorganic coating can be antiacid, so dirty compound and automobile discharge from industry discharge
Exhaust gas influence.The situation for not producing electrostatic attraction dust and being piled into dirt can reduce manyfold；7 odorless are conducive to protect
Protect ecological environment：Inorganic coating has the essence of inorganic matter, it does not contain any organic chemistry raw material or solvent, is producing and is answering
It is favourable to environmental ecology with period, characteristic odorless, without allergy；8 are adapted to all mineral construction materials：Inorganic coating is to institute
Have mineral construction material can it is compatible, rather than as it is traditional just in widely used organic coating, it is necessary to completely according to
Rely alkali prevention priming paint, to prevent the alkali on wall from attacking, nonetheless, traditional organic coating is through after a period of time, once priming paint
Destroyed by the alkali on wall, can still cause dusting, then bubble, peeling, and this problem is not present in inorganic coating.
