    The present invention relates to a process for the application of a reflecting coating on a metallic surface such as sheet metal, whereby there is applied to the unpolished metallic surface, a layer of a pulverulent dressing; said layer is subjected to a heat treatment with a view to fixing it on the metallic surface and creating a surface having undulations coexisting with micro-fissures; the layer thus fixed is smoothed by the deposit of a layer of varnish intended to fill in the micro-fissures while conserving said undulations, and the surface thus obtained is then subjected to a conventional metallization operation. The invention finds particular application to the production of reflectors having a high power of reflection.

    The invention relates to a method for applying a reflective coating on a metal surface, on a sheet metal.
    Typically, when forming a sheet metal s by stamping, this operation has a negative effect on the cleanliness of the surface of the sheet metal, which becomes deep grain. If not 10 processing this surface after aluminizing, a reflective surface with a mediocre coefficient of light output is obtained, which is caused by a significant scattering of ts of light at the site of a microcrack, small depression or similar minor defect.
    The forming operation by stamping requires polishing the obtained 20 metal surface to increase its purity. To perform this operation, it is necessary to use any fatty substance, such as, for example, animal
    fat, as a result of which an additional operation is required to degrease this surface. In addition, it is necessary to perform an additional operation, the purpose of which is to clean the surface, in particular from emery powder. This method of polishing surfaces is relatively expensive. In addition, this operation is very difficult to perform in the case of the manufacture of reflectors for automobile headlights, as in the manufacture of reflectors, the reflecting surface of which is not ring-shaped, which distinguishes the headlights currently used, it is necessary to resort to polishing devices. with very complex kinematics, which greatly complicates polishing and increases the cost of this operation.
    Given that the required degree of surface cleanliness after polishing can only be obtained by applying a special layer of a certain thickness, it is necessary to consistently apply two layers of lacquer to the heat-absorbing surface, and after applying each layer, it must be dried. After that, the surface was subjected to metallization, for example, aluminization. The closest to the invention in technical essence and the achieved result is a method of obtaining a reflective coating, for example for reflectors, by applying a metal organic resin to the metal surface, heat treating at 280 ° C and then spraying the reflective aluminum powder 1. However, a known method can be applied only on a smooth surface without cracks and defects. The purpose of the invention is to obtain a coating with a high degree of reflection on a rough surface. The goal is achieved - “by obtaining a coating on the metal surface of a polymer resin, heat treatment, dusting aluminum powder; resin used is a resin selected from the group of epoxy polyurethane, polyester, polyacrythide, heat treatment is carried out at 180220 ° C for 8-20 minutes, a phenolic or glycero-melamine resin is applied to the thermally treated surface and cured. The metal sheet to which the coating is applied has a very low degree of surface cleanliness, the state of which is further deteriorated as a result of a punching operation, allowing. Sheet metal plates are usually obtained. Usually, such sheet metal plates have a large grain size of 1-2 µm, 1 µm in depth, which causes the appearance of microcracks to significantly diffract light, which reduces its reflection coefficient. II p and me. A layer of powdered coating material, for example, of an epoxy type paint, such as an epoxy powder, produced by Belgian firm Liber (brand name Oxyplast transparency-P 1000 / 1Z C), is applied to the reflector obtained by stamping. The application of this layer is effected, for example, by electrostatic spraying. Then the coated surface is dried for 10 minutes at a temperature of about 180 ° {;. After the layer of epoxy paint is attached to the surface of the plate, the smoothing operation is performed by applying a layer of varnish. For this you can, for example, use glycero-melamine lacquer, produced by the English company International Pinshin Johnson of mark O 30 No. C or Li-phenol modified lacquer, produced by a franc of the muses company Corona of the PZ 1232 brand. . Then the treated surface is dried for 7 minutes at a temperature of about 250 ° C. Alitizing the .V i4-4x i4 "/ l Irl 1г1 ChUOS1G1K1 surface with the subsequent protection with or without processing ends the process of manufacturing the reflector. It is highly advisable to carry out an altilated method of spraying in a vacuum. 8 tab. 1 shows the polymerization conditions of the applied resins. In tab. 2 shows the comparative data on the production of reflective coatings. Thus, the invention makes it possible to obtain a coating with a high degree of reflection on a rough surface. Table
