Embodiment 1

[0020] After long-term repeated research, the applicant found that the key material that affects the performance and processing technology of artificial colored sand lies in the binder. An excellent binder needs to meet the following conditions: (1) It has super permeability, can penetrate into the interior of quartz sand, and is an artificial colored sand binder that dries at room temperature; (2) The binder must have a certain degree of hydrophilicity , to ensure compatibility with water-based resin emulsions; (3) High film-forming strength.

[0021] In order to meet the above requirements, we have successfully solved these problems through repeated research and experiments. The key lies in the way of compounding inorganic binder water glass and organic resin emulsion. The screening process of key binders and additives is set out below.

[0022] (1), the selection of the first binder - water glass

[0023] Water glass, commonly known as sodium silicate, is a water-soluble ...

Embodiment 2

[0045] Through the selection of materials in Example 1, the colorant formula determined by the present invention is shown in Table 3.

Embodiment 3

[0050] The preparation technology of composite coloring agent of the present invention, comprises the steps:

[0051] 1) Water glass acid modification step, adding inorganic acid or organic acid to water glass, and stirring for 8-15 minutes at a speed of 400-500 rpm;

[0052] 2) Add stabilizer step, drop filler into modified water glass, such as 1250 mesh mica powder, the toner of required color, drop into stabilizer while stirring, stir evenly under the rotating speed condition of 400-500 rpm Finally, disperse at a high speed for 8-15 minutes at a speed of 1450-1550 rpm;

[0053] 3) In compounding step, add water-based resin emulsion into the above-mentioned mixture obtained after high-speed dispersion, and stir to make it uniform.

Abstract

The invention provides a composite coloring agent and an artificial colored sand, and also provides a preparation method of the artificial colored sand. The artificial colored sand is prepared by using the composite coloring agent and broken stone sand, wherein the composite coloring agent comprises potash water glass, an aqueous resin emulsion, an inorganic acid or organic acid, a filler, a stabilizer, a curing agent, a toner and water; and the broken stone sand comprises at least one of quartz sand, basalt and calcite, and the particle size of the broken stone sand is 10-120 meshes. The composite coloring agent comprises, by mass, 280-320 parts of potash water glass, 45-55 parts of emulsion 996AD, 2.8-3.2 parts of concentrated sulfuric acid, 0.9-1.1 parts of silicate, 75-125 parts of mica powder, 435-560 parts of the toner and 40-52 parts of water; and a weight ratio of the broken stone sand to the composite coloring agent in the artificial colored sand is 980-960/20-40. The artificial colored sand has abundant colors, and is economic and environmentally-friendly.

Description

technical field [0001] The invention relates to a functional sand material, in particular to a composite colorant and artificial colored sand prepared by the composite colorant, belonging to the field of architectural coatings. Background technique [0002] Colored sand has been widely used in the field of architectural decoration because of its bright colors and stable performance. As a surface decoration material, colored sand is generally divided into two types: natural colored sand and artificial colored sand. Since 2000, with the rise of domestic real stone paint architectural coatings, natural colored sand resources, the main raw material of real stone paint, have been increasingly exhausted. Since 2012, affected by the smog weather in the north, the country has forced to stop the mining of most colored sand mines, resulting in the tight supply of colored sand in the coating industry and the declining quality of colored sand. The lack of colored sand resources has a n...
