Problems solved by technology

[0002] Now there are more and more types of paints on the market, and more and more functions, but in the process of use, there are mixed reviews. The problem is often not the paint itself, but the painting process, the common painting process , although the method is simple, the use effect is very poor. With the growth of time, problems such as mildew inside the board, peeling off of the surface paint, and discoloration of the paint will also appear.

Abstract

The invention discloses a water-based anti-yellowing whitening paint curtain-coating process. The process comprises the following steps that the first time of white primer curtain-coating on a woodendoor is conducted by using a curtain coater and water-based anti-yellowing whitening paint, and the second time of white primer curtain-coating is conducted after surface drying, specifically, surfacedrying is conducted for 60 minutes under the temperature of 30-40 DEG C and the humidity of 30% to 70%; then the wooden door is pulled into a drying channel and dried for 180 minutes in the drying channel with the temperature of 45-60 DEG C; then the dried wooden door is subjected to slinging operation by using a sander; the first time of white finishing coat curtain-coating is conducted, and surface drying is conducted for 30 minutes under the temperature of 30-40 DEG C and the humidity of 30% to 70% after surface drying; then the second time of water-finishing coat curtain-coating is conducted, specifically, the surface drying is conducted for 60 minutes under the temperature of 30-40 DEG C and the humidity of 30% to 70%; and the wooden door is pulled into the drying channel and dried for 180 minutes in the drying channel with the temperature of 45-60 DEG C.
