Colored flexible face brick for internal wall and external wall decoration

Abstract

The invention provides a colored flexible face brick applied to internal wall and external wall decoration, and the colored flexible face brick can widely replace ceramic tiles. The colored flexible face brick comprises, by weight, 10-20% of polymer emulsion, 1-2% of curing agents, 1.5-2.5% of plasticizers, 0.2-0.5% of thickeners, 60-75% of colored quartz sand and 12-14% of water, and the raw materials are mixed, stirred, scraped in batches and formed, cut and dried at the temperature ranging from 45 DEG C to 90 DEG C to form the face brick, the polymer emulsion is pure acrylic emulsion or silicon acrylic emulsion, the curing agents are toluene diisocyanate or diphenylmethane diisocyanate or aliphatic poly-cyanate, the thickeners are cellulose ether thickeners or polyurethane thickeners, and the colored quartz sand is colored quartz sand with the fineness being 140 meshes to 40 meshes and formed by smashing and screening natural colored minerals. The colored flexible face brick has the advantages of being simple in formula, low in cost, rich in color, good in water resistance and flexibility and the like and is an ideal material for replacing the ceramic tiles to be applied to internal wall and external wall decoration.

Description

technical field [0001] The invention relates to a building decoration material, in particular to a decoration material applied to the interior and exterior walls of buildings, and more particularly to a colorful decorative brick that can be widely used in place of ceramic tiles for decoration of the interior and exterior walls of buildings. Background technique [0002] Ceramic tiles have a long history of being used in interior and exterior wall decoration due to their unique decorative effects. However, ceramic tiles are rigid facing tiles. Changes in ambient temperature can easily cause expansion or contraction of the tiles, fatigue the bonding interface materials, and cause the tiles to dislodge from the wall. The body falls off. With the development of the economy, there are more and more high-rise buildings. The tiles fall off due to unqualified construction and materials. The weight of the tiles is generally 25Kg / ㎡-35Kg / ㎡. People's lives and properties are threatened...

Problems solved by technology

Therefore, a kind of flexible facing brick that can widely replace ceramic tiles and be used in building exterior wall decoration arises at the historic moment. Wall shedding, high safety and other advantages, but in the process of using flexible decorative bricks, there are also some unsatisfactory places, such as poor water resistance. The water absorption rate of the emulsion is high, which leads to the whitening phenomenon of the flexible facing tiles in a humid environment or after soaking in rainwater, which greatly restricts the application of the flexible facing tiles

In addition, flexibility is one of the important indicators of flexible decorative bricks. Highly flexible decorative bricks are not only suitable for different climates, but also easy to construct. The flexibility of flexible decorative bricks is usually determined by selecting acrylic emulsions with different glass transition temperatures. Adjustment, although the reduction of the glass transition temperature can improve the flexibility of the flexible facing brick, but the use of acrylic emulsion with a low glass transition temperature as the binder will reduce the water resistance of the flexible facing brick

The Chinese invention patent application with the application number 201310430552.1 discloses a technical solution for improving the water resistance and flexibility of flexible facing tiles by using polyurethane emulsion as a binder. Due to the high price of polyurethane emulsion, the use of polyurethane emulsion as a binder is bound to The cost of flexible facing bricks is greatly increased, which is not conducive to the popularization and application of flexible facing bricks
