Abstract

The invention relates to the technical field of preparation of vapor deposition materials, in particular to a preparation method of doped quartz glass vapor deposition materials. A method for preparing a doped quartz glass evaporation material, the steps comprising: (1) preparing ingredients; (2) slurry spray granulation; (3) tablet molding; (4) sintered body preparation; (5) crushing (6) melting into lumps; (7) annealing treatment; (8) crushing into granules; (9) cleaning and packaging. The present invention adopts the steps of pulverizing the sintered body of silicon-aluminum ceramics, firing and annealing, and crushing again, so that the obtained silicon-alumina glass evaporation material has a high density, and the electron gun bombards the coating material without splashing due to its light weight; there are few pores, Reduce the amount of outgassing during the coating process, thereby improving the quality of the film layer; the evaporation angle is consistent, the evaporation rate is uniform and stable, and the electron gun is easy to focus; the coating material is not easy to have dust falling off, and the coating process will not cause sputtering points, and can be applied in batches to plastics On the lens, the operability of the coating and the quality of the coating layer after coating have been greatly improved.

Description

technical field [0001] The invention belongs to the technical field of evaporation material preparation, and more specifically, the invention relates to a method for preparing a doped quartz glass evaporation material. Background technique [0002] Lenses are widely used in the fields of vehicle, security, and photography. The lens on the lens is a key optical component that determines the quality of the lens. The material of the lens in the early stage is optical glass, but the optical glass base material needs to be machined into a lens, the processing cost is high, and the product batch stability is not good. With the rapid development of plastic technology, the transmittance and other properties of plastic substrates are close to those of glass substrates. Compared with the glass substrate, the plastic substrate can be formed in one time according to the required shape, and the processing is simple and the cost is low. At present, plastic base materials have increasing...
