Abstract

The invention discloses a high-performance glass micro-bead for a reflective film and a preparation method thereof. The high-performance glass micro-bead for the reflective film is prepared by using the following raw materials in parts by weight: 33 to 45 parts of bryozoatum, 21 to 32 parts of silicon-calcium slag, 24 to 39 parts of topaz, 14 to 23 parts of rubidium carbonate, 18 to 29 parts of kaolin, 25 to 35 parts of barite, 10 to 15 parts of borax, 5 to 10 parts of calcium sulfate, 6 to 12 parts of sodium nitrate, 5 to 10 parts of barium titanate, 4 to 8 parts of potassium hexafluorophosphate and 8 to 12 parts of additive. By using industrial waste silicon-calcium slag as a main raw material and using silicon-calcium slag with components such as bryozoatum, barite, topaz, rubidium carbonate, barium titanate and potassium hexafluorophosphate in a combined manner, not only can the waste be utilized as resources, but also the comprehensive performance of the glass micro-bead is improved, the high-performance glass micro-bead disclosed by the invention has the advantages of high refractive index, high strength, good chemical stability, aging resistance, high temperature resistance, corrosion resistance and the like, and the economic benefit is good.

Description

technical field [0001] The invention relates to a high-performance glass microsphere for a 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 reflect th...
