High-strength environmental-protection colored brick tile and preparing method thereof

Abstract

The invention discloses a high-strength environmental-protection colored brick tile and a preparing method thereof, and belongs to the technical field of building materials. The colored brick tile comprises the following components: raw gypsum, diatomite, shale diatom mud, attapulgite, limestone, sodium silicate, glass fibers, fine river bottom sand, cement and an additive. The preparation method comprises the steps: respectively weighing the raw gypsum, diatomite, shale diatom mud, limestone, sodium silicate, fine river bottom sand and cement, and crushing and mixing to obtain a mixture a1; mixing evenly the mixture a1 with the attapulgite, adding water during stirring, then adding the glass fibers to the mixture, and fully stirring evenly to obtain a mixture a2; and carrying out extrusion molding of the mixture a2, curing, then spraying with a coating, and drying to obtain the colored brick tile. The colored brick tile has good mechanical strength and water permeable resistance, can effectively avoid the phenomenon of cracking in the process of using the colored brick tile, can greatly improve the service life of the colored brick tile, also has good anti-mildew effect, and effectively prevent the growth of algae around the colored brick tile.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-strength environmental-friendly colored tile and a preparation method. Background technique [0002] Colored tile, that is, colored concrete roof tile, is a building material that is extruded or molded with cement and sand as the main raw materials. It has the advantages of high strength, smooth coverage and long life. It does not use clay or sintering, saves arable land and energy, and conforms to the national industrial policy. Therefore, it is a building material that conforms to the national conditions, conforms to the times, is deeply loved by the masses, and has broad development prospects. At present, domestic roll-pressed colored tiles are prone to cracking during use, which affects the popularization and use of rolled-pressed colored tiles. [0003] The Chinese invention patent with the publication number CN104016634A discloses a roll-pressed colored...

Problems solved by technology

Although the preparation process of the color tile machine improves the water permeability of the color tile by controlling the color tile density and increases the adhesion of the pigment, the waterproof performance of the pure acrylic paint needs to be improved, and then it will also affect the color of the color tile. The overall waterproof performance is affected, and the strength of the colored tiles is only controlled by the fineness of the fine sand, the effect is not obvious
