Abstract

The invention discloses a chemical corrosion-resistant glass bead for a reflecting film and a preparation method thereof. The chemical corrosion-resistant glass bead is prepared from the following raw materials in parts by weight: 27-39 parts of granite wastes, 22-34 parts of fluorapatite, 18-26 parts of spodumene, 14-22 parts of calcium carbonate heavy, 25-35 parts of kieselguhr, 4-7 parts of ammonia alum, 16-28 parts of waste porcelain powder, 12-18 parts of plant ash, 5-10 parts of basic zirconium carbonate, 3-6 parts of potassium acetate, 4-8 parts of magnesium fluoride and 6-9 parts of additive. The glass bead prepared by combining raw materials such as the granite waste, fluorapatite, spodumene, calcium carbonate heavy, kieselguhr, waste porcelain powder, plant ash and basic zirconium carbonate in a certain proportion not only has excellent chemical corrosion resistance performance, especially is capable of resisting a strong acidic environment and a strong caustic environment, is long in service life, but also has relatively high refractive index, can meet the corrosion resistant requirements of different reflecting films and has a relatively wide application range.

Description

technical field [0001] The invention relates to a chemically corrosion-resistant glass bead for a reflective film and a preparation method thereof, belonging to the field of glass bead manufacturing. Background technique [0002] Glass microsphere is a new type of material with wide application and special performance developed in recent years. It is a hollow glass sphere with tiny size and belongs to inorganic non-metallic material. Glass beads are the main raw material for the manufacture of reflective materials, and can be widely used in reflective materials in roads, railways, airports, ports, ocean transportation, mines, tunnels, fire protection, urban construction and other fields. With the increase of my country's investment in infrastructure construction, the demand for glass beads is increasing, and the performance requirements for glass beads are also getting higher and higher. At present, only a few manufacturers in my country have mastered the production technol...
