Embodiment
For reaching fully disclosed object, below embodiment is described in further details the present invention.Should be appreciated that the specific embodiment of the following stated is only for explaining the present invention, is not intended to limit protection scope of the present invention.
Present embodiments provide a kind of automobile lamp decorative ring aluminum plating process, this technique is a kind of combination process of car light secondary film coating, and pre-treatment (also referred to as glow discharge), evaporation, secondary film coating and protective membrane can be divided into reinforce four steps.Below the concrete technology parameter of each step and effect are described in detail:
(1) pre-treatment (glow discharge): utilize high voltage electric, under vacuum conditions, carries out automobile lamp decorative ring surface active (also known as surface finish) and automobile lamp decorative ring surface cleaning by plasma.
Design parameter is: electric discharge low vacuum is 4.5 ~ 6.0 × 10 ° of Pa; Discharge time is 250 ~ 450s; Sparking voltage is 1300 ~ 1700V; Discharge fixture rotating speed is 20 ~ 35r/min.
In this step, add long discharge time, increase sparking voltage, slow down discharge fixture rotating speed, more effectively improve reactivity and the degree of cleaning on automobile lamp decorative ring surface, automobile lamp decorative ring surface finish better improves bonding force when aluminizing between aluminium lamination and automobile lamp decorative ring, namely the adhesivity of aluminium lamination, the floating dust cleaning on automobile lamp decorative ring surface relatively clean, decreases particle when aluminizing and stain.
(2) evaporation: evaporation is divided into fritting and two stages of evaporation.In the fritting stage, carry out tungsten filament aluminium wire and preheat, but do not allow it melt.Have before the evaporation to allow aluminium wire and better preheat, the generation of aluminium, white point thus control product falls apart, the whole fritting stage divides the first Pre melting process and the second Pre melting process two processes to carry out, in these two processes, use different fritting voltage and fritting time.At evaporation stage, make aluminium wire instant melting, produce aluminium steam under vacuum conditions, allow the aluminium steam produced be attached to automobile lamp decorative ring on the surface, thus make automobile lamp decorative ring luminous as mirror.
Design parameter is: evaporation vacuum tightness is 4.5 ~ 5.5 × 10
-2pa; Deposition jig rotating speed is 50 ~ 65r/min; First Pre melting process time was 16 ~ 19s; First Pre melting process voltage is 27 ~ 30V; Second Pre melting process time was 4 ~ 6s; Second Pre melting process voltage is 36 ~ 40V; Evaporation time is 25 ~ 32s; Vaporization voltage is 44 ~ 50V.
When evaporation vacuum tightness is higher than 3.5 × 10
-2during Pa, loom pumpdown time is just corresponding long, when evaporation low vacuum is in 5.5 × 10
-2during Pa, for the more difficult control of technique Burden.Appropriate fritting can reduce the generation of loose aluminium on product, white point, and evaporation adopts fast rotating speed, high-voltage, and long method controls automobile lamp decorative ring and do not turn black non-yellowing, ensures that automobile lamp decorative ring every nook and cranny can plated aluminum.
(3) secondary film coating: add layer protecting film (being commonly called as organosilicon) again to the aluminium lamination on automobile lamp decorative ring, protection aluminium lamination does not come off and is not oxidized.
Design parameter is: plated film vacuum tightness is 4.5 ~ 5.5 × 10 ° of Pa; The plated film time is 300 ~ 500s; Plated film output voltage is 1500 ~ 1800V; Coating clamp rotating speed is 20 ~ 35r/min; Organosilicon (hexamethyldisiloxane) flow is that the set(ting)value of plated film vacuum tightness adds 0.4 ~ 0.5, and the valve of manual regulation hold-up vessel sets.
Such technique initialization improves the erosion resistance of decorative circle, and in 1%NaOH reagent burette test, titration time was more than 2 hours.Hundred lattice (drawing lattice) test falls aluminium not at all.
(4) protective membrane is reinforced: dry protective membrane with ion bombardment, make it become firmer.
Design parameter is: ion bombardment time 20 ~ 50s; Ion bombardment voltage 1500 ~ 1800V;
Protective membrane quality after general plated film is soft; plated film overlong time or flow excessive; light multicolored phenomenon may be there is (namely in protective membrane; the color as rainbow is had) when product is seen sideling; utilize ion bombardment at this, improve the quality of protective membrane further, allow it toughen; protect aluminium lamination better, and the appearance of multicolored phenomenon can be reduced.
In technique scheme, automobile lamp decorative ring aluminum plating process parameter setting scope is applicable to various decorative circle product, and as planeness is different, pivoted frame height is different, and pivoted frame angle is different.And it is to be noted that the collocation of technique can at voltage, the time, rotating speed, vacuum tightness reasonably regulates.
Adopt the automobile lamp decorative ring aluminum plating process of technique scheme to improve the quality of decorative circle, decrease particle, white point, stain, blackout, jaundice, dealuminzation, the loose defect such as aluminium, the five colours.
The foregoing is only preferred embodiment of the present invention, be not used for limiting practical range of the present invention; If do not depart from the spirit and scope of the present invention, the present invention is modified or equivalent to replace, in the middle of the protection domain that all should be encompassed in the claims in the present invention.
