Embodiment 1

[0022] (1) Add 30kg of fly ash, 20kg of calcium carbide mud, and 30kg of steel slag into 100kg of water, stir and mix, and gradually add 5kg of polyvinyl alcohol. After mixing, the slurry is formed and dried in a cool place for 48 hours. The dried clay is placed at 500°C Calcined for 2h, pulverized, and sieved into particles with a particle size of 20 mesh;

[0023] (2) Add the granules obtained in step (1) to 20 kg of hydrochloric acid with a concentration of 0.2 mol / L, add 150 kg of water at a temperature of 60°C and fully stir for 10 minutes, then filter and dry;

[0024] (3) Mix the dried granules in step (2) with 80kg portland cement, 10kg gypsum powder, 5kg thixotropic agent, 2kg early strength agent, 5kg dispersant and 2kg lithopone to obtain architectural decoration Paint 1.

Embodiment 2

[0026] (1) Add 40kg of fly ash, 30kg of calcium carbide mud, and 20kg of steel slag into 120kg of water, stir and mix, and gradually add 10kg of polyvinyl alcohol. After mixing, the slurry is formed and dried in a cool place for 72 hours. The dried clay is placed at 700°C Calcined for 4h, pulverized, and sieved into particles with a particle size of 120 mesh;

[0027] (2) Add the granules obtained in step (1) to 20 kg of hydrochloric acid with a concentration of 0.4 mol / L, add 160 kg of water at a temperature of 60 to 80 ° C and fully stir for 10 to 30 minutes, then filter and dry;

[0028] (3) Mix the dried particles in step (2) with 60kg Portland cement, 20kg gypsum powder, 2kg thixotropic agent, 5kg early strength agent, 2kg dispersant and 5kg lithopone to obtain architectural decoration Paint 2.

Embodiment 3

[0030] (1) Add 35kg of fly ash, 25kg of calcium carbide mud, and 25kg of steel slag into 110kg of water, stir and mix, and gradually add 5kg of polyvinyl alcohol. After mixing, the slurry is formed and dried in a cool place for 62 hours. The dried clay is placed at 600°C Calcined for 3 hours, pulverized, and sieved into particles with a particle size of 100 mesh;

[0031] (2) Add the granules obtained in step (1) to 25 kg of hydrochloric acid with a concentration of 0.3 mol / L, add 155 °C water with a temperature of 70 ° C and fully stir for 15 min, then filter and dry;

[0032] (3) After mixing the dried particles in step (2) with 70g Portland cement, 15kg gypsum powder, 2kg thixotropic agent, 2kg early strength agent, 5kg dispersant and 2kg lithopone, the building decoration paint3.

Abstract

The invention provides an architectural ornament coating, and a preparation method and application of the coating. The architectural ornament coating is prepared by the following steps: performing pretreatment on fly ash, calcium carbide mud and steel slag to form particulate matters, carrying out denaturalization on the particulate matters, and uniformly mixing the denaturalized particulate matters with portland cement, gypsum powder, a thixotropic agent, an early-strength agent, a dispersing agent and lithopone to obtain the coating. According to the invention, problems of poor effect and short service life, which are caused by the fact that the fly ash is directly used as aggregate of a decorative material, are solved, and the other waste components can also be effectively used, so that the consumption of natural resources can be reduced, and the prepared architectural ornament coating is high in adhesive force, is elastic, has low possibility of cracking and efflorescence, is high in strength, and has outside force impact resistance.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a building decoration paint and its preparation method and application. Background technique [0002] my country's thermal power plants mainly burn coal. According to reports and statistics, in 2010, my country's thermal power industry consumed about 1.3 billion tons of standard coal and produced as much as 400 million tons of fly ash. Taking Shandong Province as an example, the coal consumption has reached 250 million tons, and the discharge of fly ash has reached nearly 80 million tons. In fact, many coal gangue and low-combustion value coal slime power plants have been put into operation in recent years to save energy. The emission of ash has increased, and the total amount is estimated to exceed 80 million tons, which is a huge amount. The stacking of fly ash not only takes up a lot of land, but also the fly ash is light in weight and small in size, which can ea...
