Aluminum section embossment wood grain surface treatment process

Abstract

The invention discloses an aluminum section embossment wood grain surface treatment process. The aluminum section embossment wood grain surface treatment process comprises the following steps of pretreatment, wood grain underpainting powder spraying, solidifying, transfer printing powder spraying, re-solidifying, wood grain transfer film packaging, covering film vaccumizing and heat transfer printing solidifying. The thickness of a sprayed wood grain underpainting coating is 60 microns or above, when heat transfer printing solidifying is carried out, wood grain on a transfer film can be permeated into the wood grain underpainting coating well, and the color retaining weather fastness of a coated film and the fidelity of wood grain texture are improved; and moreover, a wood grain die is used for carrying out spraying, the concave-convex third dimension is high, a relatively good embossment effect is achieved, the wood grain is close to the third dimension of a log better, the current situation that wood grain on the surface of the aluminum section has no third dimension or the third dimension is relatively poor, and the fidelity is not achieved enough is change, and the quality andthe aesthetic feeling of a decoration building material are improved.

Description

technical field [0001] The invention relates to the technical field of aluminum profile surface treatment technology, in particular to a surface treatment process of aluminum profile embossed wood grain. Background technique [0002] Aluminum profiles have strong corrosion resistance, non-ferromagnetism, formability and recyclability, so they are widely used in daily production and life. With the improvement of people's requirements for product packaging and decoration, the production requirements of aluminum profiles have also increased. Most people like to live in a living environment close to nature, but the practicality of using wood for decoration is low, and it is easy to corrode and decay. High-grade wood is expensive. , so the embossed wood grain aluminum profile is more and more popular. At present, there are two methods of wood grain treatment technology on the surface of aluminum profiles in China: ① thermal transfer printing technology: clear and realistic wood ...
