Description
Technical Field
The invention relates to a building material, in particular to a baking-free decorative glaze surface of an exterior wall of a building and a preparation method thereof.
Background
Since 2000, the national ministry of construction stipulates that high-rise buildings are not allowed to be decorated with ceramic tiles. Firstly, a large amount of land resources and energy resources are consumed for tile production, and the color is single, so that the city color is monotonous and tedious; secondly, the adhesive between the ceramic tile and the wall body is easy to age under outdoor conditions and has potential safety hazards of falling off and hurting people. In view of the above reasons, in the prior art, building coatings and real stone paints are generally adopted as exterior wall decoration layers of buildings, but the building coatings are exposed in the external natural environment for a long time and are subjected to long-term repeated actions such as wind blowing, sun drying, salt spray corrosion, rain, cold and hot changes, and the like, so that the coating is prone to cracking, pulverization, peeling, color change and the like, and the coating loses the original decoration function. Therefore, the building coating has the defects of poor texture, short service life and the like. The real paint is prepared by mixing quartz sand, emulsion, cellulose, a preservative and other materials, but has the problems of poor adhesive capacity, frequent sand falling, high construction environment requirement (above 20 ℃), delay of construction period, whitening and yellowing, soft coating and the like. Therefore, the development of a novel building outer wall baking-free decorative glaze surface capable of replacing the stone paint has important significance.
