Abstract

The invention relates to a high-refraction-rate glass bead partially plated with zinc sulfide. The glass bead comprises a glass bead body (1) and a zinc sulfide layer (2), wherein the zinc sulfide layer (2) covers the outer surface of the glass bead body (1), and the area of the zinc sulfide layer (2) is smaller than that of the glass bead body (1). A production process of the glass bead comprisesthe following steps: (S1) embedding beads, namely coating one surface of a base material (3) with an embedded bead layer (4), drying, and bonding the glass bead body (1) to the embedded bead layer (4); (S2) plating zinc sulfide, namely carrying out vacuum zinc sulfide evaporation on the glass bead body (1) obtained in the step (S1), and bonding the part, which does not settle into the embedded bead layer (4), of the glass bead body (1) to the zinc sulfide layer (2); and (S3) separating a finished product, namely carrying out flushing by virtue of water so as to remove the embedded bead layer(4), and separating, so as to obtain the glass bead partially plated with zinc sulfide. The production process has the advantages that the application is wide, the preparation process is simple, the cost is low, the obtained glass bead is high in quality, and the like.

Description

technical field [0001] The invention relates to the technical field of reflective material production, in particular to a partially zinc sulfide-coated high-refractive-index glass bead and a production process thereof. Background technique [0002] High refractive index glass beads are widely used in reflective materials and road markings, etc., with a refractive index between 1.90 and 2.21, mainly composed of titanium oxide, barium oxide and silicon dioxide. If only high refractive index glass beads are used, the reflective effect is not very ideal, and it is only suitable for some roads or products that do not require high retroreflective coefficients. Therefore, in practical applications, the surface of the glass beads is directly or indirectly plated with aluminum to increase the retroreflection effect. However, the application of aluminized glass microspheres is limited because they are visually gray and unable to present bright colors. It is extremely necessary to de...
