Problems solved by technology

[0002] Many ancient building walls need maintenance due to their age, but there are few special coatings on the market for ancient building walls
Although there are many types of wall coatings with different performances, most of the indoor and outdoor wall coatings on the market are not suitable as wall coatings for ancient buildings. They are prone to aging, blistering, fading, and whitening. The material of the paint is inconsistent with the material of the wall, and cannot have a physical and chemical reaction, resulting in poor bonding performance

Embodiment 1

[0023] Embodiment 1: a kind of fly ash inorganic special ancient building wall coating, it is a kind of inorganic chemical component composition, and its each component and weight (Kg) are as follows:

[0024] Finely ground fly ash: 55

[0025] Quicklime Powder: 20

[0026] Edible sucrose: 5

[0027] Water: 25

[0028] The preparation method is as follows:

[0029] Put 55kg of finely ground fly ash, 20kg of quicklime powder, 5kg of edible sucrose, and 25kg of water into a blender, and stir at a constant speed for 15 minutes to prepare a fly ash inorganic special ancient building wall coating.

Embodiment 2

[0030] Embodiment 2: a kind of fly ash inorganic special ancient building wall coating, it is a kind of inorganic chemical component composition, and its each component and weight (Kg) are as follows:

[0031] Finely ground fly ash: 50

[0032] Slaked lime powder: 25

[0033] Edible sucrose: 8

[0034] Water: 20

[0035] The preparation method is as follows:

[0036] Put 50kg of finely ground fly ash, 25kg of slaked lime powder, 8kg of edible sucrose, and 20kg of water into a mixer respectively, and stir at a constant speed for 10 minutes to prepare a kind of fly ash inorganic special ancient building wall coating.

Embodiment 3

[0037] Embodiment 3: a kind of fly ash inorganic special ancient building wall coating, it is a kind of inorganic chemical component composition, and its each component and weight (Kg) are as follows:

[0038] Finely ground fly ash: 60

[0039] Quicklime powder: 25

Abstract

The invention relates to an inorganic special historic building wall coating adopting flyash and a preparation method thereof. The inorganic special historic building wall coating adopting flyash is prepared by utilizing industrial waste residues including levigated flyash and levigated quicklime powder or levigated slaked lime powder as cementing materials and edible cane sugar as an additive. The coating is an inorganic chemical component composition comprising the following components in parts by weight: 50-60 parts of flyash, 20-30 parts of lime, 5-10 parts of edible cane sugar and 20-30 parts of water. The coating has the advantages that by utilizing the characteristic that the flyash is grey and coincides with the colors of the historic grey bricks of historic building walls, the coating has good natural color and is resistant to fading, without adding color matching pigments; meanwhile, the coating has better caking property and durability and has the function of maintaining the natural colors of historic buildings; the coating is waterproof, fireproof, antibacterial, anti-aging, nontoxic, harmless and environment-friendly and insulates heat and sound; environmental pollution is avoided in the preparation process and the using process; the flyash is recycled, so that the coating has good social and economic benefits.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a fly ash inorganic special ancient building wall coating and a preparation method thereof.
