Abstract

The invention relates to a construction process for ultraviolet light cured paint metal coating, which is characterized by comprising the following steps of: processing and drying a raw material; coating a first primer by using a roller; adjusting the energy to 350-400mj/cm2 by using an ultraviolet light drier to dry the first primer; coating a second primer by using a roller; rolling and coating the primer by using ultraviolet light; adjusting the energy to 250-300mj/cm2 by using the ultraviolet light drier to dry the second primer; polishing, dedusting and rolling and coating before sprinkling; sprinkling and coating bright varnish by using the ultraviolet light and leveling; adjusting the energy to 300-500mj/cm2 by using the ultraviolet light drier to completely dry the bright varnish to obtain a finished product. The invention has the advantages of high production efficiency, no cracking at low temperature or high temperature after coating, good adhesive force and good fullness of a paint film.

Description

technical field [0001] The invention relates to a construction technology for metal coating of ultraviolet curing paint. Background technique [0002] At present, in some decoration industries, it is necessary to wrap metal skin on the surface of some buildings. In order to beautify the design and suit the surrounding environment, sometimes painting is required. However, due to problems in the construction process, the painting is exposed to wind and rain outside. If it is exposed to the sun, the coating is easy to peel off, so it is urgent to invent a new method for the construction of the metal skin surface of the UV-curable coating. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the coating construction on the surface of the metal skin in the prior art, and to provide a method for constructing the surface of the metal skin with an ultraviolet light curing coating. The present invention design...
