Coating production technology for decorative aluminum roll

Abstract

The invention discloses a coating production technology for a decorative aluminum roll. The coating production technology comprises the following technology steps that firstly, initial cleaning is conducted, and the decorative aluminum roll is immersed in a water tank to be brushed; secondly, re-cleaning is conducted, and the decorative aluminum roll is flushed through a sprayer; thirdly, drying is conducted before coating, and the cleaned decorative aluminum roll passes through a low-temperature drying box; fourthly, coating of a skin membrane agent is conducted, and the dried decorative aluminum roll is coated with the skin membrane agent; fifthly, cooling is conducted before coating, and the decorative aluminum roll coated with the skin membrane agent is cooled through a constant-temperature box; and sixthly, preliminary coating is conducted, and spraying is conducted on the cooled decorative aluminum roll before cooling. By means of the coating production technology for the decorative aluminum roll, impurities, oil stain and sticky substances on the decorative face of the decorative aluminum roll can be thoroughly removed, and the efficiency of the drying stage before coating can be improved; and through the stepped temperature rise and temperature reduction manner, influences on the coating materials on the decorative face of the decorative aluminum roll due to sudden cooling and sudden heating are avoided, and accordingly, the coating quality of the decorative aluminum roll can be conveniently guaranteed.

Description

technical field [0001] The invention relates to the technical field of coating of decorative aluminum coils, in particular to a coating production process for decorative aluminum coils. Background technique [0002] Decorative aluminum coil is a kind of aluminum coil that is painted on it to make it have a decorative effect.
