Problems solved by technology

Since roller coating forms a thin layer of paint film on the surface of the door panel, however, there will be many small grooves on the surface of the door panel. After the paint film is coated on the surface of the door panel, part of the paint will flow into the groove, so that After the paint film dries and solidifies, a number of fine grooves are formed, resulting in a frosted surface on the surface of the paint film

Abstract

The invention discloses a UV primer and water-based finish paint roller coating process. The UV primer and water-based finish paint roller coating process comprises a UV primer process and a water-based finish paint process. According to the UV primer process, through multiple primer spraying processes and curing processes, and the obtained UV primer flat plate door is high in adhesive force. According to the water-based finish paint process, through cooperation of multiple primer and finish paint roller coating processes with the drying process, the flat plate door with good flatness can be obtained, the requirement is met, the preparation process is simple, the time is short, and the production cost is low. The requirements of an existing roller coating process can be met.

Description

technical field [0001] The invention relates to the field of paint technology, in particular to a UV primer and water-based topcoat roller coating process. Background technique [0002] Existing wooden door all can be painted on its surface, to protect wooden door and improve the aesthetic property of wooden door. The existing painting operation generally adopts a roller coating process to improve production efficiency. Before the paint is applied on the roller, the surface of the door panel of the wooden door will be polished first, and then a layer of paint film will be formed on the surface of the door panel by roller coating, and then fixed on the surface of the door panel after the paint film is dried and cured. Since roller coating forms a thin layer of paint film on the surface of the door panel, however, there will be many small grooves on the surface of the door panel. After the paint film is coated on the surface of the door panel, part of the paint will flow into...
