Problems solved by technology

At present, industrial production uses colorless and transparent glass beads, which have a single color and poor decorative effect.
Most of the preparation of colored glass beads is to prepare colored glass powder first, and then prepare colored glass beads, which has the disadvantages of high production cost, single color, and unstable color.
Especially in the preparation of bright red, brown, and yellow glass beads, the technology cannot meet the requirements

Abstract

The invention provides a preparation method for colored glass beads; and the preparation method comprises the following steps of: after uniformly mixing SiO2 powder, CaO powder, Na2O powder, K2O powder, Al2O3 powder, ZnO powder and Sb2O3 powder, forming a batch material; pouring a glass liquid after the batch material is melted into water, quenching the glass liquid in the water; grinding water-quenched glass fragments to a particle size of 10-200 microns; and then nodulizing the ground glass fragments in a bead forming furnace, so as to obtain a parent glass bead; pouring water, glycerol and dextrin into a beaker; after uniformly mixing the water, the glycerol and the dextrin, adding a mixture to a mixture of AgNO3, CuCl, Cu2O, SnO, FeSO4.7H2O, zinc powder and pulverized coal; uniformly mixing the two mixtures; and ball-milling the mixtures so as to obtain a coloring ion diffusion slurry for a colored glass bead; and mixing the parent glass bead and the coloring ion diffusion slurry so as to form a mixed material; pouring the mixed material into a stainless steel mold; heating the stainless steel mold to 550-650 DEG C; preserving the heat of the stainless steel mold for 5-10 minutes; and cooling the stainless steel mold so as to obtain ion diffused and colored glass bead. According to the invention, defects of single color, instable color, high production cost and the like in the traditional preparation method are avoided.

Description

technical field [0001] The invention relates to a method for preparing glass microspheres, in particular to a method for preparing colored glass microspheres. Background technique [0002] Glass beads are a new type of material developed in recent years with wide applications and special properties. The product is processed from silicate raw materials, with a particle size of 10-250 microns. The product has the advantages of light weight, low thermal conductivity, high strength, and good chemical stability. Its surface has been specially treated to have lipophilic and hydrophobic properties, and it is very easy to disperse in organic material systems. Glass beads have been widely used in the derusting of aerospace machinery, in the night reflective devices of zebra crossings, no-stop lines, and double yellow lines in urban traffic roads, and in the night reflective devices of traffic signs. [0003] At present, the preparation methods of glass microspheres mainly include: ...
