Wherein reflective structure body 11 mainly is to be made by the base material that aluminium, aluminium alloy, plastic cement, glass or pottery etc. are convenient to moulding, can earlier this base material be made the shape that needs, and sets gradually tie coat 12, reflector layer 13 and protective layer 14 again on its surface.Because the surface of reflective structure body 11 need apply, therefore should be bright and clean, pore-free, no burr.
It is 5～30 microns tie coat 12 that reflective structure body 11 is provided with homogeneous thickness, and this tie coat 12 is general to adopt priming paint, or the good coating material of other associativity.
Tie coat 12 surfaces are provided with the reflector layer 13 that visible light is had high reflecting rate, mainly make by the good metal of reflective function, wherein metal comprises aluminium, silver, gold, chromium, lawrencium etc., also comprise in aluminium, silver, gold, chromium, the lawrencium at least two kinds alloy, tie coat 12 thickness are generally 40～250 nanometers.
If adhesion is good between reflective structure body and the reflector layer, need not spray or be coated with tie coat 12 between reflective structure body 11 and the reflector layer 13, directly with reflector layer 13 spraying or be coated on reflective structure body 11 surfaces, when adopting glass as base material; Otherwise then needing increases adhesion with priming paint, when adopting fine aluminium, aluminium alloy, plastic cement as base material; During as base material, can select whether to need to be coated with tie coat with pottery according to actual needs.
Reflector layer 13 surfaces are provided with the protective layer 14 that can absorb ultraviolet ray and see through visible light; protective layer 14 can adopt and be coated with layer or coating, when protective layer 14 when being coated with layer, its thickness is 40～200 nanometers; when protective layer 14 was coating, its thickness was 3～10 microns.Protective layer 14 is made by metal oxide or metal mixture; wherein metal oxide comprises one or more in ceria, tantalum pentoxide, titanium monoxide, titanium dioxide, yittrium oxide, titanium sesquioxide or the five oxidation Tritanium/Trititaniums; metal mixture can be a zirconium titanium mixture; above material have have stable high-temperature performance, cheap, absorb ultraviolet ray and do not absorb advantage such as visible light, specific nature is as shown in table 1 below.
Table 1 is used for each material physical property of protective layer

The concrete steps of reflective structure preparation provided by the present invention are as follows:
The first step is made a reflective structure body earlier, and the material of selecting for use can be base materials such as aluminium, aluminium alloy, plastic cement, glass, pottery, because its surface needs plated film, therefore should be bright and clean, and forming defects such as pore-free, no burr.
Second step, according to the pollution condition of reflective structure body in manufacturing process, use correspondingly that cleaning fluid cleans, commonly used have alkali cleaning or a pickling.
The 3rd step, for guaranteeing vacuum evaporation coating quality, spraying one deck tie coat on the reflective structure body surface, be generally priming paint, priming paint and reflective structure body and reflector layer afterwards will all have good adhesion, and need meet the heatproof requirement, and this thickness of crossing coating is generally 5～30 microns, and should apply evenly, its effect has:
1) by priming paint sealing base material, the volatile materials when preventing vacuum coating in the base material is overflowed, and influences coating quality;
2) substrate surface is more coarse, by the priming paint preliminary treatment, can obtain smooth smooth mirror effect;
3) base material that surface polarity is lower adhesive force common and coating is relatively poor, can obtain adherence of coating energy preferably by coating prime lacquer, and improve reflection efficiency;
4) to the relatively poor base material of some heat resistance, priming paint can play the slow effect of heat, and the protection base material exempts from thermal-induced deformation.
The 4th step, the reflective structure body that scribbles priming paint is carried out drying, can select different drying modes according to the kind of priming paint, commonly used have high temperature drying and a ultraviolet curing drying.
The 5th step was coated with the reflector layer that can improve reflecting rate on the tie coat surface, and this reflector layer can be metals such as aluminium, silver, gold, chromium, lawrencium, or their alloy, the thickness of reflector layer preferably between 40 nanometers～250 nanometers, has approached very much easy light leak, and too thick then hot tearing performance is bad.
The 6th step; vacuum is coated with or application one deck can absorb ultraviolet protective layer on the reflecting coating surface; this protective layer can absorb in the ultraviolet metal oxide one or more by ceria, tantalum pentoxide, titanium monoxide, titanium dioxide, yittrium oxide, titanium sesquioxide, five oxidation Tritanium/Trititaniums etc. and make; the physical property of various materials is as shown in table 1; or can absorb ultraviolet metal mixture by some, make as zirconium titanium mixture etc.
The coating that protective layer can be coated with or apply; but single sometimes rete is limited to ultraviolet absorption; weatherability for better ultraviolet ray filtering, raising protective layer; can consider to be coated with or coated with multiple layer; but no matter the number of plies what; its gross thickness generally remains a stationary value, if it is bad to have approached very much the effect of ultraviolet ray filtering, and the too thick reflector efficiency that then influences reflective structure.If be coated with layer, thickness generally is about 40～200 nanometers, if coating, its thickness is about 3～10 microns.
Wherein, reflector layer and protective layer all can be coated with under vacuum condition; with the coating material is that cerium di-oxide layer is an example; concrete operations are; in order to eliminate the moisture that coating materials inflammability impurity and its strong hygroscopicity form, must earlier the base material that scribbles priming paint be toasted or sintering under 800～1100 ℃ high temperature in air, again under vacuum condition; tungsten sheet with 0.4～0.5 millimeters thick is made the evaporation boat, heating evaporation coating material ceria (CeO
2), it is deposited on be gets final product on the about 50 ℃ reflective structure body 18 inches away from evaporation source more than.
Energy provided by the present invention absorbs ultraviolet reflective structure, not only can be used for being prepared into the reflector of light fixture, can also be used for the reflector surface, enumerates two object lessons below and is illustrated.
