Abstract

The invention discloses a method for preparing a weather-resistant silver mirror which is suitable for trough solar thermal power generation. The silver mirror orderly consists of a transparent low-iron super white float glass substrate, a first Al2O3 adhesive layer, an Ag reflective layer, a second Al2O3 adhesive protective layer, a SiOx protective layer and at least two waterproof protective macromolecule paint layers. The preparation method thereof comprises the step of: adopting a multi-target intermediate frequency response vertical magnetic control sputtering coater, respectively and orderly plating the first Al2O3 adhesive layer, the Ag reflective layer, the second Al2O3 adhesive protective layer, the SiOx protective layer and the at least two waterproof protective macromolecule paint layers and preparing the weather-resistant silver mirror of the invention. The inventive preparation method has the characteristics of advanced and reasonable preparation method, low preparation cost, low energy consumption, high reflectivity of the prepared weather-resistant silver mirror, reliable work, long service life and the like.

Description

technical field [0001] The invention relates to a method for preparing a weather-resistant silver mirror, in particular to a method for preparing a weather-resistant silver mirror suitable for large-area curved focusing and high-efficiency reflection for trough solar thermal power generation. Background technique [0002] People's understanding of solar thermal power generation technology has reached a very high level, especially the trough solar thermal power generation technology, which has entered the commercial era. [0003] The trough solar thermal power generation technology uses solar energy (light) to focus on the heat pipe with medium water in the middle through the high-efficiency reflection silver mirror, so that the medium water is vaporized and pressurized in a short period of time, and finally the high-pressure steam drives the turbo generator generate electricity. [0004] It can be seen that an important factor determining the efficiency of the trough solar ...
