Durable concrete colored tile

Abstract

The invention provides a durable concrete colored tile and a preparation method thereof. The durable concrete colored tile comprises the following raw materials in parts by mass: 40 to 80 parts of cement, 20 to 60 parts of modified fly ash, 10 to 30 parts of modified calcium carbonate, 20 to 60 parts of fine sand, 10 to 40 parts of stone chips, 18 to 55 parts of water, 4 to 16 parts of a polymer emulsion, 1 to 6 parts of fiber, 0.1 to 1 part of a water reducing agent, 1 to 5 parts of color tile paint and 1 to 5 parts of a sealant. The durable concrete colored tile provided by the invention hasgood mechanical properties and impermeability, has high bearing capacity after freezing, does not generate color-fading and color-losing phenomenons in 5 years, and is free of cracks on a coating.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a durable concrete colored tile and a preparation method thereof. Background technique [0002] In recent years, concrete colored tiles have become one of the mainstream products used in houses in China. In my country, there are thousands of colored tile factories producing concrete colored tiles. However, different manufacturers use different materials and coloring processes to produce different quality tiles. colored tiles. However, in the current market, the colored tiles in concrete manufacturers generally have problems such as poor coloring of colored tiles, short-term color retention, easy pulverization of the color layer, and color difference in colored tiles. The colored tiles produced are usually used for 2 to 3 years. There will be fading and fading, which will seriously affect the appearance of the city. Therefore, it is necessary to produce a kind of colored tile, wh...

AI Technical Summary

Problems solved by technology

The other is: use paint spraying, the spraying color is bright, and the dry film thickness of general spraying is about 35 μm or more. However, the problem of this spraying process is that the ordinary concrete tile embryo has poor mechanical properties and large porosity. Directly spray paint on the tile embryo surface. Due to the large porosity of concrete, the amount of paint used is large, the cost is increased, and the adhesion between the spray paint and the surface of ordinary concrete tile embryos is weak. After a long time of application, the paint will fall off, and the durability of ordinary concrete tile embryos is poor. And other issues
