The preparation method of described decoration mortar, is characterized in that comprising the following steps:
(1) by diatomite, sepiolite, ironic hydroxide mixing, 140-180 order particle is ground into;
(2) by calcium chloride, Tai-Ace S 150, sodium sulfate, alum powder, sodium lauryl sulphate, sodium abietate, carboxylic styrene butadiene latex, water mixing, stir and obtain slurry;
(3) by auxiliary agent, flyash, vegetables oil mixing, dispersion grinding 20-30 minute, obtains mixture;
(4) mixing of materials other remaining components and (1) step, (2) step, (3) step obtained is even, and stirring reaction 10-15 minute, to obtain final product.
Beneficial effect of the present invention
Mortar good leveling property of the present invention, easy application, good endurance, containing diatomite, sepiolite, can purify air, not containing toxic substance, not efflorescence; The application of the invention auxiliary agent, improves the resistance to compression of mortar, folding strength, improves workability, sag resistance, thixotropy and anti-settling.
