The invention provides an optical coating material for an optical lens, which is prepared from the following raw materials by weight percentage: 50-90% of nano-silicon dioxide, 3-25% of magnesium fluoride, 1-10% of aluminum oxide, five Tantalum oxide 1~10%, yttrium oxide 1~10%, zirconium dioxide 1~5%. The preparation method of the invention is simple, and the prepared optical coating material is used for the optical coating material of the optical lens. Zirconium oxide is matched with three high refractive index materials, and alumina, a medium refractive index material, is added to prepare an optical coating material with medium refractive index, high transmittance, wear resistance, high temperature resistance, Good chemical stability, when used in optical lenses, it can meet different medium refractive index and high transmittance, and also has the characteristics of wear resistance, which can prolong the service time of optical lenses. |
