Problems solved by technology

The disadvantages of using this process are: 1. It is necessary to build a large-scale production line and configure a sewage treatment system at the same time, and the production cost is relatively high; 2. The steps of adding patterns using the thermal transfer process can only be done manually, which requires a large number of configurations operators, further increasing manufacturing costs

Abstract

The invention discloses a steel plate coating technology for ink-jetting a pattern by adopting an inkjet machine to solve the technical problem of high production cost of steel plate coating technologies in the prior art. The steel plate coating technology is characterized in that a steel plate is sequentially coated with a PVC protection layer, an aqueous color coating layer, a gloss oil layer and a protection film. The steel plate coating technology comprises the following steps: 1, the steel plate is coated with a PVC paste after undergoing a surface treatment process, and the PVC paste isplasticized at a high temperature to form the PVC protection layer; 2, aqueous ink is ink-jetted on the PVC protection layer through the inkjet machine to ink-jet the pattern, and the aqueous ink is dried with ultrasonic rays to form the aqueous color coating layer; 3, the aqueous color coating layer is coated with gloss oil, and the gloss oil is dried with ultraviolet rays to form the gloss oil layer; and 4, the protection film is attached to the gloss oil layer.

Description

【Technical field】 [0001] The invention relates to a steel plate coating process. 【Background technique】 [0002] The steel plate coating process steps in the prior art are electroplating - pickling - phosphating treatment - passivation treatment - plastic spraying - adding patterns by heat transfer printing - packaging. The disadvantages of using this process are: 1. It is necessary to build a large-scale production line and configure a sewage treatment system at the same time, and the production cost is relatively high; 2. The steps of adding patterns using the thermal transfer process can only be completed manually, which requires a large number of configurations. Operators further increase the manufacturing cost. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a steel plate coating process using a spray-painting machine to spray patterns, which can realize a large-s...
