Abstract

The invention relates to lens materials, in particular to a high-temperature-resistant optical lens material. The high-temperature-resistant optical lens material is prepared from, by weight, 35-46 parts of polyurethane resin, 23-36 parts of organic silicon resin, 3-6 parts of high-temperature-resistant material, 4-9 parts of chain extension agent, 2-7 parts of cross-linking agent, 1-5 parts of light stabilizer, 1.5-4.5 parts of ultraviolet light absorber, 2.5-4 parts of antioxidant and 1-5 parts of polylactic acid. The optical lens material has excellent high-temperature resistance.

Description

technical field [0001] The invention relates to a lens material, in particular to a high temperature resistant optical lens material. Background technique [0002] An optical lens is an optical component made of a transparent substance. The selection of optical lens materials is restricted by factors such as molding difficulty, light transmittance, cost and stability, and glass and transparent plastics are generally selected. Compared with traditional glass lenses and plastic lenses, silicone lenses show excellent characteristics in terms of light transmittance, molding difficulty, and aging resistance. However, the temperature resistance of existing silica gel lenses is generally -60-250°C, and the light transmittance is about 90%. The high temperature resistance and transparency are still not ideal, which limits its application in phototherapy instruments and the like. Contents of the invention [0003] Based on the technical problems existing in the background technol...
