Embodiment

[0033] One of the embodiments, as attached figure 1 Shown:

[0034] A weather-resistant silver mirror especially suitable for trough solar thermal power generation technology and equipment, comprising a transparent substrate 1, and a first Al plated on one side of the transparent substrate 1 2 O 3 Adhesive layer 2, plated on the first Al 2 O 3 The Ag reflective layer 3 on the surface of the adhesive layer 2, and the second Al plated on the surface of the Ag reflective layer 3 2 O 3 Adhesive protective layer 4, second Al 2 O 3 The surface of the adhesive protection layer 4 is coated with a SiOx protection layer 5. On the surface of the SiOx layer 5, at least two waterproof protective polymer paint layers 6 are also coated. The SiOx protective layer 5 is SiO 2 The protective layer. When the polymer paint layer 6 is two layers, the inner polymer paint layer 6-1 is a two-component epoxy quick-drying silver mirror protective paint UE307 layer, and the outer polymer paint layer 6-2 is...

Abstract

The invention discloses a weather-resistant silver mirror which is particularly suitable for trough solar thermal power generation and a preparation method thereof. The silver mirror orderly consists of a transparent substrate, a first Al2O3 adhesive layer, an Ag reflective layer, a second Al2O3 adhesive protective layer and a SiOx protective layer. The preparation method thereof comprises the step of orderly and respectively plating the first Al2O3 adhesive layer, the Ag reflective layer, the second Al2O3 adhesive protective layer and the SiOx protective layer by adopting a multi-target intermediate frequency response vertical magnetic control sputter to prepare the weather-resistant silver mirror of the invention. The finished product of the weather-resistant silver mirror of the invention has the characteristics of high reflectivity, reliable work, long service life and the like. The preparation method of the invention has the characteristics of advance, reasonability, low cost, low energy consumption, good quality of the finished product and the like.

Description

Technical field [0001] The invention relates to a weather-resistant silver mirror and a preparation method thereof, in particular to a weather-resistant silver mirror with a large area curved focus and high efficiency reflection suitable for trough solar thermal power generation and a preparation method thereof. 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] Trough solar thermal power generation technology uses solar energy (light) to focus on the heat pipe with medium water in the middle through high-efficiency reflective silver mirrors, so that the medium water is vaporized and pressurized in a short time, and finally the high-pressure steam drives the turbo generator Power generation. [0004] It can be seen that an important factor that determines the efficiency of the trough solar therma...
