The specific embodiment
The invention provides a kind of nanocomposite optical electricity-saving lamp reflector manufacture method; described method comprises the following steps: the aluminium sheet raw material is adopted to multiple reflection corner angle mould; die cast; then carry out spraying priming paint in chemical polishing, surface treatment, cleaning by degreasing, drying, stove, solidify; through vacuum coating and plating nano protective film step, form the reflector formed by nanometer high brightness crystalline solid glass property composition protective film, reflective aluminum rete, prime coat and aluminum die casting reflector backplane level afterwards.
Concrete steps are:
1, mold: by changing die-casting forming die, reflecting surface forms intensive multiple reflection corner angle, by vacuum coating, forms minute surface, reach multiple spot, multi-angle alternating reflex, give full play to source efficiency, effectively avoid blackening, the shade of light fixture, make its brightness increase, uniform-illumination.
2, aluminium sheet raw material: adopt the high minute surface aluminium sheet of Germany peace aluminium MIRO4, reflectivity high (reaching 95%), be easy to moulding, and surface is hard is difficult for scratch, can directly process without pretreatment, and hardness is even, is applicable to complicated punch forming, bending, stretching, integer and is difficult for breaking.This material minute surface is that the processing of machine glazed finish formula generates, surperficial electroless plating.
3, die cast: by changing the multiple reflection corner angle angle of reflector die-casting forming die, can reach reflection angle and the distribution curve flux of multiple demand, to reach, be applicable to the desired purpose of various illuminated fields.
4, chemical polishing:
1), charging: advanced luggage material before chemical polishing, requiring that the basic principle of charging is produced with the common anode oxidation is identical.Need the reflector of chemical polishing should be without defects such as serious scratch, scuffing, corrosion, to guarantee to obtain satisfied brightness.The corresponding minimizing of charge, spacing, gradient will strengthen, and gas is overflowed as early as possible.The relative density of chemical polishing tank liquor is very large, and the gas just formed in polishing is attached to the reflector surface, likely makes the conducting beam floating, and the reflector chemical polishing of emersion liquid level part is just insufficient, causes and the phenomenon that brightness is inhomogeneous occurs in same bridging.In case of necessity, reduce charge or adopt the large-scale conducting beam increased the weight of to prevent the reflector floating.Reflecting surface should outwards vertically be feeded, and guarantees that the gas on this face is overflowed as early as possible.Charging will adopt fixture firm, notes avoiding staying on reflecting surface the fixture vestige while using fixture fixedly.
2), Chemical cleaning degreasing: before the reflector chemical polishing, particularly through the reflector surface of machine glazed finish, may contain grease, adopt high-temperature water or high-temperature steam to clean untotally.Now adopt the water-soluble chemical cleaning agent that contains surfactant to clean, can effectively remove the grease on reflector surface.
3), stir: in the reflector chemical polishing, have gas to overflow, if tank liquor does not stir, be difficult to make gas to hightail the reflector surface, form gas buildup.Gas buildup is upwards overflowed because of bubble when a certain amount of, makes surface cause the gas striped.Adopt the uniformity that the mechanical agitation mode is carried out suitably, stirring uniformly can guarantee the reflector Surface Chemical Polishing.
4), the time: required time of reflector chemical polishing, limiting polishing time was in order to prevent the generation of gas defects at 1-3min.
5), temperature: temperature has important impact to efficiency and the surface quality of reflector chemical polishing.The high polishing efficiency of temperature accelerates, but produce more gas, overflows, and likely produces gas defects.For the chemical polishing tank liquor of new preparation, should notice that temperature should not be too high; If molten aluminium amount reaches certain equilibrium level, it is high that the temperature of chemical polishing tank liquor is wanted.Along with the increase of molten aluminium amount, maintain the temperature that certain polishing efficiency will increase tank liquor.Once 105 ℃ of the ceiling temperatures that the temperature of tank liquor surpass to be set, still can not reach satisfied brightness, common need to adjust tank liquor concentration or the adjustment relative density directly related with concentration.
6), the transfer after the reflector chemical polishing: after chemical polishing, reflector should be transferred in rinsing bowl and be washed rapidly.If shift not rapidly, will there will be the defect that shifts etch.Because the chemical polishing tank liquor be attached on reflector is very viscid, reflector one goes out groove, cooling rapidly from very high temperature, chemical reaction is also continuing, gas is constantly overflowed, nitric acid content descends very fast, and in surface liquid, molten aluminium amount constantly raises, and more and more departs from the process conditions of normal chemical polishing necessity.If it is slightly slow that reflector shifts, the defects such as etch just likely appear shifting.
7), washing: the reflector washing is the finishing operation of chemical polishing process, and being attached to chemical polishing tank liquor viscid on the reflector surface must clean up, and adopts warm water (40 ℃) washing circulated.
8), ash disposal: transfer to after reflector washing in the tank liquor of ash disposal and carry out ash disposal, the nitric acid (relative density 1.40) that is 25%-50% containing volume fraction in the tank liquor of ash disposal usually.After reflector surface ash disposal is processed, check the surface quality of chemical polishing, answer smooth.If surface also is attached with the characteristic color of slight copper, show that ash disposal is insufficient, need to supplement the ash disposal time, increase in case of necessity the nitric acid content in the ash disposal tank liquor.
5, drying: adopt drying and processing.
6, spraying priming paint in stove: the reflector performance depends on the quality of film plating layer, and the key of coating process quality is to be decided by the prime coat quality.Although can do at present without the priming paint plated film, but because the problems such as deficiency of die quality and cost and reflecting brightness exist, therefore adopt spraying priming paint in stove also to solidify and make it produce highlighted surface (pollution-free residue), thoroughly solved this technical barrier.
7, vacuum coating: vacuum coating need to be carried out under higher vacuum, will be reflected cover base material to be coated and be contained in vacuum evaporation plating machine, with vavuum pump, vacuumizes, and makes vacuum reach 1.3 * 10
-2～1.3 * 10
