Mineral glass beads for road markings

Abstract

The invention relates to mineral glass beads for road markings, which relates to optical glass beads and solves the problems of low refractive index and poor reflective brightness of the current glass beads for the road markings. The mineral glass beads for the road markings are the optical glass beads, wherein the glass beads are prepared from the following components in part by weight: 40 parts of sandstone, 28 to 32 parts of barite, 1835 to 22.5 parts of diamond, 2.5 parts of datolite, 2 parts of feldspar, 4 parts of mirabilite and 2 parts of smithsonite. The mineral glass beads can be widely used in road markings of airfield runways and high-level roads.

Description

technical field

[0001] The invention relates to an optical glass bead. Background technique

[0002] Glass beads for optics are a special glass product in the glass industry. It has certain chemical stability, high mechanical strength, good electrical insulation, integrity, uniformity, good fluidity, and does not contain any toxic heavy metals. It is safe And no pollution. Its most unique performance is that it has the original transparency of glass and the regression of directional reflection. However, the existing glass beads used for road markings have low refractive index and poor reflective brightness. Contents of the invention

[0003] The object of the present invention is to solve the problems of low refractive index and poor reflective brightness of existing glass beads used for road markings, thereby proposing a kind of ore glass beads used for road markings.
