Abstract
The invention discloses a glass bead used for a highway-engineering-grade light reflection film and a preparation method for the glass bead. The glass bead is prepared from the following raw materials in parts by weight: 36-54 parts of dickite, 28-42 parts of cancrinite, 12-18 parts of magnesium carbonate, 22-36 parts of calcite, 44-68 parts of silica powder, 18-29 parts of kyanite, 6-12 parts of calcium tetrafluoroborate, 7-13 parts of antimonous oxide, 5-10 parts of coke powder,4-9 parts of lithium niobate, 5-10 parts of potassium chloride and 9-14 parts of additives. According to the glass bead, the lithium niobate, the calcium tetrafluoroborate, the calcite, the dickite, the cancrinite, the kyanite and the silica powder have synergistic effect, and the raw materials act with one another, so that not only can the ageing resistance and the high temperature resistance of the glass bead be improved, but also the mechanical strength and the optical performance of the glass bead can be improved. The glass bead prepared by the preparation method disclosed by the invention has the advantages such as high strength, high brightness of reflected light, high temperature resistance, ageing resistance and the like, is long in service life, safe and reliable, and can be widely applied to the highway-engineering-grade light reflection film.
Description
technical field [0001] The invention relates to a glass microsphere used for road engineering grade reflective film and a preparation method thereof, belonging to the field of glass microsphere manufacture. Background technique [0002] Glass beads refer to solid or hollow glass beads with a diameter of several microns to hundreds of microns, which are divided into two types: colorless and colored. Those with a diameter of 0.8mm or more are called fine beads; those with a diameter of less than 0.8mm are called microbeads. Glass beads are a new type of silicate material, which are widely used because of their characteristics of transparency, adjustable refractive index, directional retroreflection, smooth surface, good fluidity, electrical insulation, stable chemical properties, heat resistance and high mechanical strength. Applied to reflective film. [0003] The reflective film is based on the principle of retro-reflective glass beads with high refractive index. It can r...
