Solar energy reflectors (1) according to the present invention comprise a mirror (5) laminated to a support (6) by means of a bonding material (9) comprising a foam tape.
Description
Technical field
The present invention relates to solar energy reflection body and manufacture method thereof.
Reflector of the present invention can be used in solar energy or heating facility, for example concentration solar generating equipment.Such facility uses solar energy at first to produce heat, and described heat can be subsequently converted to electricity or be used for steam and produce.Wherein can use the concentration solar generating equipment of reflector of the present invention to comprise for example parabola slot type generating equipment, concentrated tower-type electricity generation equipment (also referred to as settled date mirror generating equipment), disc type heat collector and Fresnel (Fresnel) reflection generating equipment.Solar energy reflection body of the present invention can be used in this class facility of plane mirror or curved surface mirror.
Background technology
The solar energy reflection body can be made by the lamilated body that formation comprises the thin mirror that is attached to support chip, and described support chip has the surface size substantially the same with this mirror.If mirror is thin, can obtain its maximum reflectivity, therefore when passing the base material of mirror, solar energy less absorbed.But thin mirror may be bad aspect mechanical resistance, therefore may need they are laminated on support base material such as sheet metal.This mirror and support base material form single laminate structures.In addition alternatively, the solar energy reactor can use mirror as follows to make, and described mirror is adapted to not to be used supporting pieces and, for this mirror provides enough mechanical resistances, for example has the mirror of larger thickness.Bracing or strutting arrangement can be connected on mirror to be used for the fixed solar facility and/or can help to keep the curve form of mirror.
Known by means of epoxy resin, based on organosilyl adhesive, polyurethane binder, hotmelt, acrylic resin based adhesive or polyvinyl chloride binder course, mirror layer is incorporated on their supporter.Usually find advantageously to comprise acrylic resin for bond material.In some cases, epoxy resin, organic siliconresin and polyurethane resin can discharge chemical substance, the skin of paint of described chemical substance erodable mirror and finally corrode silver layer; When occurring when crosslinked, epoxy resin can produce tensile stress between the skin of paint of mirror and silver layer, and this can cause separating in mirror structure; Hotmelt can lose its flexible at least a portion when being exposed to higher temperature, this can cause separating of mirror and support chip; When sheet metal expanded in the temperature difference that stands to operate, some were based on organosilyl material (for example structuring organosilicon) rigidity too, and this can cause that the paint of mirror and silver layer are drawn out; Organosilicon can produce planar disfigurement during laminated; Polyurethane resin may be not enough to the opposing ultraviolet ray.Acrylic resin may demonstrate advantage aspect chemically neutral, ultraviolet repellence and flexible and elasticity.Perhaps alternatively, bond material can comprise EVA (ethylene vinyl acetate) or other polymer film based on acetate, PVB (polyvinyl butyral resin), TPU (thermoplastic polyurethane) or based on the film of ionomer.These materials can demonstrate favourable character aspect chemically neutral, ultraviolet repellence and flexible and elasticity.Other known bond material can comprise acrylic psa, and this can be used as transfering belt (transfer tape) and provides, and wherein adhesive is present between two supportive releasing pieces that are intended to be removed.Perhaps alternatively, it can be used as support type adhesive tape (supported tape) and provides, and wherein adhesive provides on the both sides of the support chip that is intended to keep.Such support type adhesive tape for example comprises the core that basically PET film or polyester foil, consists of, and this core is surrounded by the layer that basically the pressure-sensitive resin of acrylic compounds, consists of.
