Abstract
The utility model relates to a curved mirror with high specular reflection, which comprises curved glass, a hot melting film and a glass mirror, wherein the hot melting film is arranged on the surface of the curved glass; an integral plane thin glass mirror is arranged on the hot melting film; the curved glass, the hot melting film and the glass mirror are shaped into a lamellar curved structure; the specular reflection has high accuracy; and the metal reflection layer is completely sealed, thereby ensuring high weather resistance, corrosion resistance, service life as long as decades and long-term use in various complex environments in the open air; the curved mirror has the advantages of simple structure, low cost, stability, durability, and safe and reliable use; and the curved mirror is widely applicable to various solar energy heat-collecting focuses and solar heat power generation as well as the solar energy high and intermediate temperature environments.
Description
Technical field
The utility model belongs to the glassware field, relates to a kind of curved mirror with height direct reflection.
Background technology
Existing curved mirror generally is to be adopted by the many thin glass mirror small pieces of number manually to be adhesive on the bigger bend glass, this small pieces scatter the curved mirror of bonded structure, its minute surface optically focused performance quality is poor, the direct reflection precision is low, there are bubble weatherability and corrosion resistance relatively poor more between each thin glass mirror small pieces and the glue, influence serviceable life.Also having a kind of is the curved glass genus membrane structure of gilding, because the pattern on surface is relatively poor after the glass high temperature hot bending, what diffuse reflection can not reach regulation more by force behind the metal film reflection horizon requires serviceable life also shorter, can not be used for demanding occasion of direct reflection such as solar energy thermal-power-generating.
Summary of the invention
The purpose of this utility model is to provide a kind of curved mirror with height direct reflection of being combined closely by thin mirror of integral planar and bend glass hot bending, minute surface optically focused excellent performance, and direct reflection precision height, weather resistance is good, and is sturdy and durable.
The technical solution adopted in the utility model: a kind of curved mirror with height direct reflection, comprise by bend glass, hot-melt film, glass mirror, described bend glass surface is provided with hot-melt film, and hot-melt film is provided with the thin glass mirror of integral planar, and the three is shaped to the stratiform curved-surface structure.
Described bend glass has curvature, and the curved surface of bend glass is the combination of parabola, arc surface or parabolic and arc surface.
Described glass mirror is selected float glass process flat thin glass mirror for use, and the mirror reflection surface of flat thin glass mirror is outside.
The utility model compared with prior art has following advantage:
1. adopt thin glass mirror of integral planar and bend glass moulding, both combinations are closely even, minute surface optically focused excellent performance, direct reflection precision height;
2. metallic reflector is sealed fully, does not have bubble weather resistance excellence, and not perishable, the life-span is decades, can use for a long time down by various out of doors complex environments;
3. simple in structure, cost is low, and is sturdy and durable, safe and reliable; Can be widely used in various solar energy heatings and focus on, solar energy thermal-power-generating, and in other sun power medium and high temperature, use.

Embodiment
Consult shown in Figure 1, a kind of curved mirror with height direct reflection, be shaped to the stratiform curved-surface structure by bend glass 1, hot-melt film 2, flat thin glass mirror 3 threes, it is the high-quality float glass process flat thin glass mirror of 0.5-1.5mm that its glass mirror 3 is selected thickness for use, bend glass 1 has curvature, thickness is 3-5mm, and length and width be all greater than glass mirror 3, and hot-melt film 2 is selected the weather resistance multipolymer (EVA), polyvinyl butyral (PVB) etc. of high-quality ethene and vinyl acetate preferably for use.
Described bend glass 1 surface coated has hot-melt film 2, be equipped with whole thin glass mirror 3 on the hot-melt film 2, the mirror reflection surface of glass mirror 3 is outside, the three is put into the flexible poly-bag of vacuum to vacuumize and makes it to combine closely, intensification is melted hot-melt film 2, with flat thin glass mirror 3 and bend glass 1 closely evenly in conjunction with the required curvature of curing molding, thereby form curved mirror with height direct reflection.
The curved surface of described bend glass 1 is parabola, arc surface or combinations such as parabolic and arc surface.
Claims (3)
1. one kind has the highly curved mirror of direct reflection, comprise by bend glass, hot-melt film, glass mirror, it is characterized in that described bend glass (1) surface is provided with hot-melt film (2), hot-melt film (2) is provided with the thin glass mirror (3) of integral planar, and the three is shaped to the stratiform curved-surface structure.
2. the curved mirror with height direct reflection according to claim 1 is characterized in that described bend glass (1) has curvature, and the curved surface of bend glass (1) is the combination of parabola, arc surface or parabolic and arc surface.
3. the curved mirror with height direct reflection according to claim 1 is characterized in that described glass mirror (3) selects float glass process flat thin glass mirror for use, and the mirror reflection surface of flat thin glass mirror (3) is outside.
