Anti-corrosion anti-frost-crack glass microspheres for reflective film and preparation method thereof

Abstract

The invention discloses anti-corrosion anti-frost-crack glass microspheres for a reflective film and a preparation method thereof. The anti-corrosion anti-frost-crack glass microspheres are prepared by using the following raw materials in parts by weight: 29-37 parts of wollastonite, 23-35 parts of turquoise, 26-38 parts of bauxite, 18-32 parts of obsidian, 14-22 parts of crumbled calcium carbide, 22-34 parts of sodalite, 15-20 parts of calcium carbonate, 10-15 parts of aluminum dihydrogen tripolyphosphate, 12-18 parts of zinc phosphate,16-22 parts of barium sulfate, 5-10 parts of neodymia, 4-8 parts of ceric hydroxide and 5-10 parts of an additive. According to the anti-corrosion anti-frost-crack glass microspheres, raw materials such as turquoise, bauxite, obsidian, crumbled calcium carbide, sodalite, aluminum dihydrogen tripolyphosphate, zinc phosphate, neodymia, and ceric hydroxide are used. The anti-corrosion anti-frost-crack glass microspheres produced in accordance with the formula of the invention are resistant to low temperature and resistant to corrosion especially corrosion caused by acid or alkali, so that the glass microspheres can work for a long period of time at low temperature or in corrosive media without reflective properties being harmed, thereby improving the application value of the glass microspheres and achieving excellent comprehensive performance.

Description

technical field [0001] The invention relates to a corrosion-resistant, frost- and crack-resistant glass microsphere for a reflective film and a preparation method thereof, belonging to the field of glass microsphere manufacturing. 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 re...

Problems solved by technology

At present, the quality and performance of glass microspheres produced by Chinese manufacturers are unstable, and there are still disadvantages such as poor corrosion resistance and poor frost crack resistance, and there is still a certain gap compared with foreign glass microspheres.
