Embodiment Construction

[0017] As follows, the application scheme is further described:

[0018] A coating process for improving the performance of reflective cups, comprising the following steps:

[0019] Step 1. Place the workpiece in the cavity of the processing furnace, fill it with argon gas after vacuuming, and clean the surface of the workpiece by ion current bombardment, and perform vacuum discharge to treat impurities on the surface of the workpiece, and also have the effect of activating the surface; the volume flow rate of argon gas The control is at 200 sccm, the cleaning time is 180s, and the rotation frequency of the workpiece is 10Hz.

[0020] Step 2. Coating the base film of dimethyl silicone oil on the workpiece under the condition of ion current bombardment by chemical vapor deposition. The volume flow rate of dimethyl silicone oil is controlled at 150 sccm, and the ion current with intermediate frequency power of 1.6A is used. The coating time is controlled at 180s, the rotation f...

Abstract

The invention provides a coating process for improving performance of a reflection cup. The coating process for improving the performance of the reflection cup comprises the following steps that step1, a workpiece is placed in a processing furnace cavity, after vacuumizing is carried out, the processing furnace cavity is filled with argon gas, and the surface of the workpiece is cleaned by ion current bombardment; step 2, the workpiece is coated with a dimethyl silicone oil base film under the condition of ion current bombardment by a chemical vapor deposition method; step 3, the workpiece iscoated with an aluminum film by an evaporation mode, and the workpiece is subjected to evaporation by pure aluminum at a high temperature of 1100-1200 DEG C, wherein the purity of the pure aluminum is 99.99 %; and step 4, the workpiece is coated with a dimethyl silicone oil protective film under the condition of ion current bombardment by a chemical vapor deposition method. The coating process for improving the performance of the reflection cup has high light efficiency, high film layer stability, less material consumption and reduced cost.

Description

technical field [0001] The invention relates to a coating process, in particular to a coating process for improving the performance of a reflective cup. Background technique [0002] As an accessory of the lamp, the reflective cup mainly plays the role of concentrating the light effect. The reflective effect of the reflective cup mainly depends on the excellent reflectivity achieved by the coating on the reflective cup. [0003] Before the existing reflector is coated, it is necessary to spray UV primer, the thickness of which is about 16-22nm, which is used to cover some defects of the product (such as parting line, material flower); and it is necessary to spray UV primer to make the coated film Gloss, if you don't spray UV oil, the electroplating layer is dull and easy to fall off. After the coating is completed, it is necessary to spray UV surface oil (with a thickness of 16-22nm) to protect the electroplating layer, so that the electroplating surface has better wear res...
