Abstract
The invention belongs to the technical field of building wall preparation, and particularly relates to a preparation method of self-cleaning curtain wall stones. The preparation method comprises the following steps: (1) preparing a curtain wall stone blank; (2) Preparing a mixture of modified nano cerium oxide, nano tungsten disulfide and nano zinc phosphate; (3) preparing a mixture of modified wollastonite and coal gangue; (4) preparing a self-cleaning coating liquid; and (5) preparing the self-cleaning curtain wall stone. The preparation method of the self-cleaning curtain wall stone has the advantages of simple process, easy parameter control, mutual matching of the curtain wall stone blank and the self-cleaning coating liquid, and excellent crack resistance, mechanical property and compactness of the curtain wall stone blank; the self-cleaning coating liquid has excellent hydrophobicity, wear resistance and antibacterial property; the two components act synergistically to ensure that the prepared curtain wall stone has excellent pollution resistance, hydrophobicity, antibacterial property and mechanical property.
Description
Technical Field
The invention belongs to the technical field of building wall preparation, and particularly relates to a preparation method of self-cleaning curtain wall stones.
Background
The curtain wall is an outer wall enclosure of a building, is not load-bearing, is a light wall body with decorative effect commonly used in modern large-scale and high-rise buildings, and consists of a panel (glass, aluminum plate, stone plate, ceramic plate and the like) and a supporting structure system (aluminum beam upright post, steel structure, glass rib and the like), and can have certain displacement capacity or certain deformation capacity relative to a main structure, and the outer wall enclosure structure or the decorative structure does not bear the function of the main structure. In recent years, dry-hanging ceramic curtain walls in China are increasingly used in high-rise buildings, and the ceramic curtain walls are connected with a main body structure in a mode of back bolts, buckling grooves, bolts and the like. Ceramic curtain walls (porcelain curtain walls) are curtain walls which use building ceramic plates as main materials. The building ceramic plate has excellent physical and chemical properties, hardness and strength higher than Huang Gangdan, uniform and compact texture, high hardness, high strength and stable chemical properties, and the excellent properties are derived from the microstructure of the building ceramic plate. The ceramic curtain wall is made of polycrystalline material and mainly comprises innumerable micron-sized quartz grains and mullite grains to form a grid structure. These fine grains are bonded to the ceramic glass body into which they are fused at high temperature to form a dense whole. These grains and glass bodies have high strength and hardness, and the bonding strength between the grains and the glass bodies is quite high. The microstructure enables the ceramic curtain wall to have a series of characteristics of low water absorption, high strength, bending resistance, corrosion resistance, weather resistance and the like. When the curtain wall is built, steel frame sections are not needed, and the curtain wall can be reliably installed on a base wall surface (main body structure) by using a small amount of stainless steel expansion bolts and connecting pieces under most conditions, so that the manufacturing cost of the curtain wall is greatly reduced, and the curtain wall is a curtain wall material which is very worthy of popularization.
At present, ceramic curtain walls have poor pollution resistance, especially in areas with more dust content in the atmosphere and serious air pollution, the ceramic curtain walls are extremely easy to be scaled by Meng Chenna, and the cleaning is time-consuming and labor-consuming, so that the attractiveness is greatly reduced, and therefore, the exploration of curtain wall stones with self-cleaning performance is very important.
