Problems solved by technology

However, because the colorant on the outer surface of the aggregate in the sintered colored sand is bonded with the aggregate and then sintered at a medium and low temperature, the colorant on the surface forms a hard and brittle package. The shell, once attacked, will crack or break off, revealing the color and texture of the original aggregate sand, and there is also another quality problem;
[0008] 3. The surface coloring layer of both dip-dyeing and sintering-type colored sand is relatively rough, and the phenomenon of uneven surface color can be seen through careful observation, especially...

Abstract

The invention relates to colored sand capable of coloring by reaction and its preparation method, the colored sand is prepared by the following components: 100wt parts of aggregate, 1.0-5.0wt parts of adhesive and 0.2-3.5wt parts of colouring agent; wherein the aggregate is other sandstone such as basalt sand, quartz sand, yellow sand or sea sand; and the colouring agent is composed 30.0-45.0wt parts of intensifying agent, 50.0-65.0wt parts of fluxing agent, 2.5-7.0wt parts of colour former and 50.0-80.0 wt parts of clear water according to a mechanism of ceramic colored glaze. The preparation method is characterized in that the colouring agent and the adhesive through grinding are coated on the surface of the aggregate together, then dried and calcined under the temperature of 700-950 DEG C to obtain the reaction-type colored sand. The colored sand has the advantages of uniform coloring, bright color and various types; a color layer is combined with the aggregate through reaction, and has the advantages of fastness and stabilization, no fading, strong corrosivity resistance, good weatherability and long usage life.

Description

technical field [0001] The present invention relates to a colored sand for building materials, in particular to a colored sand used on the surface of asphalt tiles colored by using a reaction. When changing the aggregate type and particle size in the production raw materials, it can also be used for the surface of modified asphalt waterproofing membranes, the aggregate of real stone paint thick coatings for building exterior walls, and the texture and color of art murals and other products. superior. Background technique [0002] At present, the colored sand supplied on the existing market in my country mainly includes two series of natural colored sand and artificially colored colored sand. Among them, artificially colored colored sand is divided into two types: dip-dyeing type and sintering type. [0003] Natural colored sand has few color varieties, and the color is light but not bright. Moreover, due to the uneven distribution of colors in the rock ore, the large diff...
