Abstract

The invention relates to a full-aluminizing high-refractive-index glass microbead. The full-aluminizing high-refractive-index glass microbead comprises a glass microbead body (1) and an aluminizing layer (2), wherein the aluminizing layer (2) completely covers the outer surface of the glass microbead body (1); the refractive index of the glass microbead body (1) is 1.90-2.21; the thickness of the aluminizing layer (2) is 300 angstroms to 1,200 angstroms. The production process comprises the following steps: S1, planting a bead; S2, aluminizing once; S3, compounding; S4, peeling and aluminizing for the second time; S5, removing a planted bead resin layer B (6) to obtain the full-aluminizing glass micro bead. The full-aluminizing high-refractive-index glass microbead and the production process thereof, which are provided by the invention, have the advantages that the coating thickness is controlled by a coating machine, and the operation is simple; because the planted bead resin layer B is water soluble resin, and is soluble in water, the aluminized glass micro bead can be conveniently separated away from a base material, and the appearance cannot be damaged, and the product percentage of pass is high; the full-aluminizing high-refractive-index glass microbead is high in retroreflection coefficient, and a light reflection effect is good.

Description

technical field [0001] The invention relates to the technical field of reflective material production, in particular to an all-aluminized 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. [0003] Some aluminum-plated high-refractive index glass beads have unique applications in the fields of reflective ink, clothing, accessories, etc., and play the role of reflective ...
