Described lime is the fine grinding quicklime powder of the content of free calcium oxide more than 50% or levigate slaked lime powder, and the fineness of described fine grinding quicklime powder or levigate slaked lime powder is that 0.9mm tails over the meal being less than 1%.

Described edible sucrose is brown sugar, white sugar, brown sugar or loaf sugar.

Described flyash is fine-ground fly-ash, refers to that its fineness is that 45 μm of square hole sieves tail over the meal being less than 10%.

Another technical scheme of the present invention is: the preparation method of the extraordinary ancient architecture wall coating of a kind of fly ash inorganic, by flyash 50 ~ 60 weight part, lime 20 ~ 30 weight part, edible sucrose 5 ~ 10 weight part and water 20 ~ 30 weight part, put into agitator respectively, at the uniform velocity stir 5 ~ 15 minutes, be namely prepared into the extraordinary ancient architecture wall coating of fly ash inorganic.

Described lime is the fine grinding quicklime powder of the content of free calcium oxide more than 50% or levigate slaked lime powder, the fineness of described fine grinding quicklime powder or levigate slaked lime powder is that 0.9mm tails over the meal being less than 1%, described edible sucrose is brown sugar, white sugar, brown sugar or loaf sugar, described flyash is fine-ground fly-ash, refers to that fineness is that 45 μm of square hole sieves tail over the meal being less than 10%.

The present invention utilizes industrial residue---and fine-ground fly-ash, fine grinding quicklime powder or levigate slaked lime powder are gelling material, and additive edible sucrose is brown sugar, white sugar, brown sugar or loaf sugar, prepare the extraordinary ancient building coating of fly ash inorganic.It is a kind of inorganic chemistry component combine thing, is applicable to ancient architecture wall protection coating, is also applicable to newly-built building in the style of the ancients coating for wall surface, its compared with prior art tool have the following advantages:

1, the present invention utilizes the characteristic that the ancient blue bricks color of flyash gray and ancient architecture wall matches, need not additional toner pigment, has that Natural color is good, the performance of fade resistant.Easily there is discolouration phenomena in traditional coating, the present invention utilizes flyash to have firmly material Natural color, and color resistance is strong, not fugitive color.

2, coating of the present invention is the composition of inorganic chemistry component, and itself and ancient architecture wall material are identical material, and both can play physical-chemical reaction, makes it to have cohesiveness and weather resistance is better, keeps the functions such as the true qualities of ancient building.Adhesive property of the present invention is better than traditional coating, and the extraordinary ancient architecture wall coating of fly ash inorganic of the present invention is novel green inorganic materials, and can play physical-chemical reaction with construction material, feature, the adhesive property with later strength are more superior.

3, can play physical-chemical reaction after flyash and the material mixing such as lime, edible sucrose in coating of the present invention, coating surface strength is better, and cohesiveness is strong, and be more conducive to anti-aging, weather resistance is strong.

4, coating of the present invention possesses the function such as waterproof, fire prevention, heat insulation, sound insulation, antibacterial, anti-foaming, slip-off preventing, resist chemical, anti-pole fever and chills simultaneously.

5, to prepare starting material, preparation process and use procedure coating all nontoxic in the present invention, and non-environmental-pollution, the feature of environmental protection is good.

6, preparation method is easy, and raw material is easy to get and with low cost, so that product cost of the present invention is low, and economic benefit is good.

7, fully utilize flyash (industrial residue), turn waste into wealth, protection of the environment, benefits the nation and the people, and has good Social benefit and economic benefit.
