Manufacturing technology of piano paint furniture

Abstract

The invention discloses a manufacturing technology of piano paint furniture. The technology comprises the steps of S1, selecting materials, namely, selecting a density board base material with high bending resistance and high weather resistance, and selecting unsaturated polyester PE piano paint; S2, carrying out preprocessing, namely, curing and drying the density board base material; S3, carrying out cutting, namely, cutting a density board into furniture parts meeting forming size based on furniture to be processed, and shaping and processing the cut furniture parts; S4, carrying out sanding, namely, processing the processed furniture parts by secondary PE sealing and drying, and then carrying out sanding through an abrasive belt mechanism so as to reach the optimal flatness of the board surface and the optimal adhesion force in surface coating; and S5, processing a bottom layer, namely, coating the board surface with putty to obtain the bottom layer for painting. Compared with other piano paint technologies, the manufacturing technology of the piano paint furnace is low in technology price, saves the space, and is mature; and the technology has the characteristics of being extremely high in glossiness, extremely high in specular gloss, ultrahigh in hardness, and clear and uniform in color, and severe paint film falling off and white coating falling off problems can be effectively avoided.

Description

technical field [0001] The invention relates to the field of furniture coating, and more specifically, relates to a manufacturing process for piano baking varnish furniture. Background technique [0002] The piano baking varnish process is a kind of baking varnish process. Its process is very complicated. Compared with ordinary high-gloss spray paint, piano varnish has two essential differences. First, the piano paint has a very thick primer layer. In fact, if the surface layer of real piano paint is broken hard, it will crack like enamel instead of peeling off like ordinary paint; second, Piano paint is a baking process, not a spraying process, and has undergone a high-temperature curing process. [0003] However, the so-called piano paint that is popular in the market is actually PU (polyurethane paint), which is a matte paint. Moreover, the paint film is easy to yellow, age and fall off, and the surface has apertures, swirls or wrinkled skin, without mirror effect. Ther...

[0003] However, the so-called piano paint that is popular in the market is actually PU (polyurethane paint), which is a matte paint. Moreover, the paint film is easy to yellow, age and fall off, and there are apertures, swirls or wrinkled skin on the surface, without mirror effect. For this reason, we propose a piano baking varnish furniture manufacturing process
