Abstract
A method for coating an antifog layer on the surface of the light distributing mirror for headlight includes such steps as cleaning the mirror by electrostatic dusting, automatic spray coating at a moving speed of 200-300 mm/s to obtain a coated layer with 2-10 microns in thickness, and baking at 70-120 deg.C for 4-10 min.
Description
Technical field
The present invention relates to a kind of method of vehicle lamp light-distributing mirror being carried out anti-mist coating.
Background technology
As everyone knows, the essential characteristic on the surface of liquid is to tend to shrink, and especially when external force is very little to its influence, drop is tending towards sphere, as at the globule on glass.Lens on the light fixture of vehicle is very easy to long-pending mist in steam, it is the surface that airborne steam condenses upon lens, and will influence the illumination of car light greatly behind the knot of the lens on the light fixture of the vehicle mist, directly hinder traffic safety, in order to prevent that steam is at lens surface knot mist, people have invented anti-fog coating, anti-fog coating is a kind of coating of low surface tension, when the anti-fog coating of low surface tension is coated on lens surperficial, hydrophilic molecules in the coating is arranged in the surface of lens, make original hydrophobic surface become hydrophily, make the surface tension of its surface tension near water, and the coacervation of steam does not take place, not because not condensing of steam, vapour concentration in the car light cavity and the extraneous relative dynamic balance that keeps, so lamp does not produce fog in the chamber yet, but the design of lens is carried out in strict accordance with GB, so as when carrying out the coating of anti-fog coating, need certain technical requirements on the lens surface, as arbitrarily spraying the light distribution characteristic that then can change lens, influence the normal illumination of car light.
Summary of the invention
The objective of the invention is a kind ofly can on the lens of car light, carry out anti-fog coating, and after coating, satisfy the method for the anti-mist coating of car light light distribution requirements again.Technical scheme of the present invention is a kind of method of vehicle lamp light-distributing mirror being carried out anti-mist coating of design, it is characterized in that by the following step: (1) utilizes the electrostatic precipitation rifle to carry out dedusting the lens of desire coating, (2) utilize automatic spray apparatus to spray lens, the lens after (3) will spray is put into baking oven dries.The nozzle of automatic spray apparatus is 150 for the spray distance of lens in the described step (2)---200 millimeters, the nozzle translational speed of its automatic spray apparatus is 200---300 mm/second, coating thickness are 2---10 microns.The bake out temperature of baking oven is 70 in the described step (3)---120 ℃, drying time is 4---10 minutes.Advantage of the present invention is after to vehicle lamp light-distributing mirror spraying anti-fog coating, and coating is even, and the lens of itself and car light has good adhesive force, can keep the light distribution requirements of lens.
Below in conjunction with embodiment the present invention is elaborated:
The specific embodiment
At first the lens with the desire coating utilizes the electrostatic precipitation rifle to carry out dedusting, usually as the case may be, generally carry out the dedusting more than 10 seconds, subsequently lens is placed on the automatic spray apparatus and sprays, the nozzle of automatic spray apparatus and the spray distance of lens are 150---between 200 millimeters, for the coating thickness of the coating that guarantees to spray 2---between 10 microns, the nozzle translational speed of automatic spray apparatus should elect 200 as---between 300 mm/second, lens after the spraying is put into baking oven dries, the bake out temperature of baking oven is 70---120 ℃, drying time is 4---and 10 minutes.Meet dust generation albefaction for the anti-fog coating that prevents to be sprayed on the lens, be placed on after the lens after the oven dry need pack in the environment more than 50 ℃.
Selecting spray distance in the enforcement is 200 millimeters, and the coating thickness of coating is at 5 microns, and the nozzle translational speed of automatic spray apparatus is 250 mm/second, and the bake out temperature of baking oven is 100 ℃, and drying time is 6 minutes.
Claims (3)
1, a kind of method of vehicle lamp light-distributing mirror being carried out anti-mist coating, it is characterized in that by the following step: (1) utilizes the electrostatic precipitation rifle to carry out dedusting the lens of desire coating, (2) utilize automatic spray apparatus to spray lens, the lens after (3) will spray is put into baking oven dries.
2, by the described a kind of method of vehicle lamp light-distributing mirror being carried out anti-mist coating of claim 1, it is characterized in that: the nozzle of automatic spray apparatus is 150 for the spray distance of lens in the described step (2)---200 millimeters, the nozzle translational speed of its automatic spray apparatus is 200---300 mm/second, coating thickness are 2---and 10 microns.
3, a kind of vehicle lamp light-distributing mirror is carried out the method for anti-mist coating by claim 1 is described, it is characterized in that: the bake out temperature of baking oven is 70 in the described step (3)---120 ℃, drying time is 4---10 minutes.
