Example Embodiment

[0031]As an embodiment of the present invention, the preparation method of the optical glass includes the following steps:

[0032]S1: Silica, trioxide, trioxide, trioxide, lithium oxide, and cerium oxide into hot melt, control the temperature of the thermal fuser in the hot melt gas to 1350 to 1550 ° C In the middle of the thermal insulation melting 2 to 3 h, 0.5 h during the smelting process, the mixed solution in the hot melt is stirred for 5 min, and the stirring rate is 45 to 60 r / min; the intervalness is stirred, and the melting substance can effectively accelerate the melting material. The blending is blended, and at the same time, the spacing can be effectively allowed to stand, so that impurities in the raw material are subjected to epithelial, and thereby producing a lower mixed solution having a lower hybrid after melting.

[0033]S2: The nano-titanium dioxide and fish oil are sequentially added to the mixture of 2 to 3 h after 2 to 3 hours of S1, and control the temperature ...

Abstract

The invention belongs to the technical field of optical glass, and particularly relates to optical glass which comprises a glass layer and a protective layer. The protective layer coats the outer side of the glass layer; the protective layer is made of an elastic solid material; the optical glass is prepared from the following raw materials: 8-10 parts of silicon dioxide, 24-25 parts of lanthanum trioxide, 16-20 parts of diboron trioxide, 8-12 parts of nano titanium dioxide, 5-8 parts of aluminum oxide, 5-8 parts of lithium oxide, 1-1.6 parts of barium oxide, 2-4 parts of fish oil, 8-6 parts of microcrystalline wax, 8-10 parts of low molecular weight polyethylene resin, 12-16 parts of polyamide-6, 2-3 parts of calcium oxide and 3-5 parts of heat-conductive carbon fibers. The optical glass is of a two layer structure and the protective layer is added to the outer layer, so that the shock resistance and the corrosion resistance of the optical glass can be effectively enhanced, and meanwhile, a cleaning process before secondary molding pressing or precise molding pressing is omitted, so that the process of preparing optical parts by precise molding pressing of the optical glass is more convenient.

Description

technical field [0001] The invention belongs to the technical field of optical glass, in particular to an optical glass. Background technique [0002] In the prior art, for optical glass, the refractive index, Abbe number, and transmittance are its core characteristics. The refractive index and Abbe number determine the basic functions of the glass. The refractive index is 1.81-1.88, and the Abbe number is 31. The optical glass of -38 belongs to high refractive index, medium and high dispersion optical glass, which can shorten the imaging length of the lens. When used in conjunction with low refractive index and low dispersion glass, it can effectively eliminate the chromatic aberration of the lens. Most of the process is prepared by secondary molding or precision molding, which makes the preparation of optical glass divided into two main steps: blanks and finished products. The process of processing blanks into finished products is accompanied by transportation and storage....
