Abstract

The invention discloses high-temperature sintered painted sand and a preparation method thereof. The painted sand comprises silicate mineral particles and a surface toner layer, wherein the surface toner layer is formed by calcining color paste wrapping the surface of the silicate mineral particles at high temperature. The preparation method comprises the following steps: selecting and screening the silicate mineral particles; preparing the color paste, namely mixing water glass, kaolin, industrial borax and inorganic pigment with water according to the required color situation, and performing ball-milling; mixing the prepared color paste with the silicate mineral particles according to a weight ratio in a rotary drum furnace, and drying; after mixing and drying through the rotary drum furnace, calcining at high temperature, and after the calcining process is finished, feeding to the outlet of a calcining furnace; cooling and storing, namely cooling finally to prepare the high-temperature sintered painted sand. According to the preparation method, the operation is easy, the continuous production can be performed, the color adjustment of the painted sand is easy to control, the color consistency control of the painted sand can be ensured, the production is simple and quick, the cumbersome process in which frits need to be used is removed by optimization, the energy consumption is reduced, and the large-scale application is facilitated.

Description

technical field [0001] The invention relates to the field of colored sand, in particular to a high-temperature sintered colored sand and a preparation method thereof. Background technique [0002] Colored sand is divided into natural colored sand and artificial colored sand. The large-scale application of artificial colored sand is on the asphalt tiles of villas in western countries. A layer of inorganic basalt colored sand particles is embedded on the upper surface of the asphalt tiles to achieve a beautiful effect. It also plays a role in enhancing the weather resistance of roof asphalt tiles. Due to the various advantages of asphalt tiles, artificial asphalt tile colored sand can be used on a large scale at the earliest; the color of natural colored sand is not bright, the color difference is large, and there are few color varieties. At the same time, due to the country's gradual regulation and restriction on random digging in recent years, the raw materials of natural co...
