Example Embodiment

[0045] figure 1 It is a cross-sectional view of a curved mirror according to an embodiment of the present invention. figure 1 In this case, the curved mirror 2 is cured and molded by a flat glass structure 6, an intermediate adhesive layer 7 and a flat glass mirror 8 to form a curved mirror with a composite structure.

[0046] Specifically, the flat glass mirror 8 can be a high-quality float flat glass mirror body, and preferably a non-edged and / or non-tempered glass with a thickness of 1.8-2 mm. The flat glass structure 6 is a single-layer flat glass, and its thickness is preferably 1.8-2 mm unedged and / or untempered glass. The intermediate adhesive layer 7 has a certain thickness, for example, greater than 0.1 mm, preferably greater than 0.2 mm, and can be selected as high-quality ethylene vinyl acetate copolymer (EVA) sheets or polyvinyl butyral (PVB) sheets. Or, the intermediate adhesive layer 7 can also be an adhesive layer composed of high-quality EVA, PVB sheets and fixed ...

Abstract

The invention provides a curved mirror reflector (2), which comprises a flat glass structure (6), a middle bonding layer (7) and a flat glass mirror (8), wherein the flat glass structure (6) and the flat glass mirror (8) are processed by non-edging and/or non-tempered common glass; the middle bonding layer (7) is located between the flat glass structure (6) and the flat glass mirror (8), and is bent and deformed under support of a mould through a mechanical manner, and the bent and deformed flat glass structure (6), the middle bonding layer (7) and the flat glass mirror (8) are solidified and bonded to a composite curved surface structure through a heating and/or normal-temperature solidification manner. The curved mirror reflector (2), provided by the invention, can be widely applied in all kinds of fields of solar thermal collection and focus and solar thermal power generation.

Description

technical field [0001] The invention relates to the field of glass products and processing, in particular to a curved reflector applied in the field of solar energy and a manufacturing method thereof. Background technique [0002] At present, in many industrial installations, especially in solar concentrating systems, concentrating mirrors of various shapes are often used. Concentrating mirrors mainly include trough parabolic mirrors, curved parabolic mirrors, curved spherical mirrors, etc.; and micro-curvature heliostat concentrating mirrors or zero-curvature plane mirrors in the tower power generation mirror field. [0003] Typically, curved mirrors are obtained by deforming flat mirrors or flat glass. There are two types of forming processes for curved mirrors: one is the high-temperature thermal deformation manufacturing method, and the other is the mechanical cold deformation manufacturing method. [0004] The high-temperature thermal deformation manufacturing method ...
