Problems solved by technology

[0005] Glass beads have a continuous glassy structure, basically no crystallization, and are prone to linear fractures during use. Their mechanical toughness and reflective life cannot better meet people's further requirements for material properties.
[0006] There are reports about ceramic microbeads in the prior art, but it has a high cost relative to the market usage of microbeads, and has not been popularized
In addition, there are also related reports on polymer microbeads, but they are extremely prone to aging and lose their reflective properties, and no further research has been obtained.

Abstract

The invention provides a transparent glass-ceramic composite micro-bead material and a preparation method thereof. The transparent glass-ceramic composite micro-bead material includes an inner core and an outer shell and is characterized in that the inner core is glass micro-beads, and the outer shell is made of a ceramic material; the particle diameter of the glass micro-beads is 10-20 microns; the ceramic material is composed of the components according to the mole ratio: 1-2 of ZrO2, 0.1-0.2 of SiO2, 0.2-0.4 of Al2O3, 0.05-0.1 of MgO, and 0.02-0.15 of Y2O3; and the particle diameter of the transparent glass-ceramic composite micro-bead material is 25-45 microns. The transparent glass-ceramic composite micro-bead material has the hardness, crushing resistance, abrasion resistance and sphericity all greater than those of the glass micro-beads having the same particle diameter, and has the refractive index of about 1.9-2.2.

Description

technical field [0001] The invention relates to a transparent glass-ceramic composite bead material, in particular to a transparent glass-ceramic composite bead material used for reflective instruments and a preparation method thereof. Background technique [0002] Reflective materials, also known as retroreflective materials or retroreflective materials, include reflective film, reflective ink, reflective marking paint, reflective cloth, reflective leather, reflective webbing and reflective safety silk fabrics. The principle is to introduce a high refractive index glass bead or triangular prism microlattice structure on the surface of the corresponding material, and reflect the light back to the light source according to the original path, thereby forming a retroreflection phenomenon. Under the light, the reflective material has a visual effect hundreds of times more eye-catching than other non-reflective materials. When light is incident on an item containing retroreflect...
