Described modified coal ash is made by the raw material of following weight part:

Flyash 20-30, Pericarppium arachidis hypogaeae 4-6, aluminum oxide 1.5-2.5, rapeseed meal 10-12, clorafin 1-2, epoxy soybean oil 1-2, dioctyl maleate 1.2-2.3, aluminium hydroxide 8-10;

The preparation method of described modified coal ash is:

After flyash, Pericarppium arachidis hypogaeae are stirred, calcining 4-5 hour under 600-650 ℃, then, take out, soak 5-8 hour in the acetic acid solution that is 5-8% in concentration, then, after mixing with aluminium hydroxide, rapeseed meal, aluminum oxide, add in suitable quantity of water and grind, adding 10-15% hydrochloric acid soln tune PH is 4.4-5.2, ground slurry is to the 400-500 order, and the repeated hydrogenation sodium oxide is adjusted to neutrality, drying, the gained powder is mixed with other remaining component, ground and mixed evenly and get final product again.

Described a kind of thermal insulation mortar is characterized in that:

The preparation method is:

To calcine desulfurization gypsum powder, cement, redispersable latex powder, calcium sulphate retarder mixes by weight, stir 5-8 minute under 300-400 rev/min, take out, again with the residue whole raw material blendings after, 100-200 rev/min is at the uniform velocity stirred 10-20 minute, again the material three-roll grinder that is stirred is ground to 2-3 hour, after packing and get final product.

Beneficial effect of the present invention is: high insulating effect of the present invention, and preparation technology is simple, and ultimate compression strength is high.

Flyash 28, Pericarppium arachidis hypogaeae 5, aluminum oxide 1.8, rapeseed meal 12, clorafin 2, epoxy soybean oil 1, dioctyl maleate 2.3, aluminium hydroxide 10;

The preparation method of described modified coal ash is:

After flyash, Pericarppium arachidis hypogaeae are stirred, under 650 ℃, calcining is 4 hours, then, take out, soak 8 hours in the acetic acid solution that is 8% in concentration, then, after mixing with aluminium hydroxide, rapeseed meal, aluminum oxide, add in suitable quantity of water and grind, adding 10% hydrochloric acid soln tune PH is 4.8, after ground slurry to 500 order, the repeated hydrogenation sodium oxide is adjusted to neutrality, drying, the gained powder is mixed with other remaining component, ground and mixed evenly and get final product again.

Described a kind of thermal insulation mortar,

The preparation method is:

To calcine desulfurization gypsum powder, cement, redispersable latex powder, calcium sulphate retarder by weight kg mix, under 400 rev/mins, stir 8 minutes, take out, again with the residue whole raw material blendings after, 200 rev/mins are at the uniform velocity stirred 15 minutes, again the material three-roll grinder that is stirred is ground 3 hours, after packing and get final product.

The products obtained therefrom test result is as follows:
