preparation example Construction

[0035] Such as figure 1 Shown, a kind of preparation method of sintered colored sand is characterized in that, comprises the steps:

[0036] Step 1, preparing each component according to the weight ratio: sand grains, binder, coloring agent and bonding agent, for subsequent use;

[0037] Step 2, the above-mentioned components are evenly stirred;

[0038] Step 3, sintering the above-mentioned uniformly stirred mixture in a rotary kiln at 200-400 degrees for 30-40 minutes to obtain a sintered product;

[0039] Step 4, the above-mentioned sintered product is taken out of the furnace and cooled to obtain sintered colored sand.

Embodiment 1

[0041] Example 1: Take 1000 parts of quartz stone, 25 parts of binder, 10 parts of coloring agent and 3 parts of caking agent, stir the above-mentioned components evenly, and sinter in a rotary kiln between 200-400 degrees for 30- For 40 minutes, finally, the sintered colored sand was obtained by cooling out of the furnace.

Embodiment 2

[0042] Embodiment 2: Take 1000 parts of quartz stone, 30 parts of binder, 15 parts of coloring agent and 5 parts of caking agent, stir the above-mentioned components evenly, and sinter in a rotary kiln between 200-400 degrees for 30- For 40 minutes, finally, the sintered colored sand was obtained by cooling out of the furnace.

Abstract

The invention discloses sintered colored sand and a preparation method thereof. The sintered colored sand contains sand grains, a color inorganic coating is wrapped on the external of the sand grain; the color inorganic coating contains adhesive, coloring agent and fluxing agent, wherein the sand grain and the color inorganic coating contain the following components in part by weight: 900-1100 parts of sand grain, 20-50 parts of adhesive, 5-35 parts of coloring agent and 1-10 parts of fluxing agent. The sintered colored sand disclosed by the invention has the advantages of being low in production cost, small in energy consumption, firm in colored sand coloring, good in weather resistance and long in anti-ageing time; through the adoption of the preparation method of the sintered colored sand disclosed by the invention, the sintering temperature can be obviously lowered, and the method has the advantages of being simple and easy in color control, and simple in process.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a sintered colored sand and a preparation method thereof. Background technique [0002] Colored sand is mainly divided into natural colored sand and artificial colored sand. Natural colored sand is a resource product. With the pressure of domestic environmental protection, the supply of natural colored sand will be more and more restricted; artificial colored sand is divided into resin dyed colored sand. Sand and inorganic sintered colored sand, resin dyed colored sand, although rich in bright and rich colors, but its products are easy to fade, fade and poor color resistance; sintered colored sand is made of inorganic pigments and inorganic high-temperature adhesive The colored sand is fired with cement, and its colored sand has firm coloring, good weather resistance and long anti-aging time. [0003] See Chinese invention patent application number: 200610037985.0, wh...
