Car headlight is a familiar automobile part frequently used in our everyday life. It is able to reflect converged light given off from a bulb to one hundred meters away by the high reflectivity of headlight shade. Currently, 95% of headlight shades are aluminized by vacuum metallizing machines. However, the vacuum aluminizing process has fatal weakness, i.e. the oxidation. Here we also take headlight shade as example that aluminized layer on it is easy to get oxidated and as time goes on the surface of headlight shade will become yellow and turn dark, gravely tampering with its reflectivity. Contemporarily, many factories solve this problem by the process of transparent varnishing spraying as protective top coating after aluminizing coating. But by the technology of transparent varnishing there have following problems:
