A kind of aluminum profile embossed wood grain surface treatment technology

Abstract

The invention discloses a surface treatment process for embossed wood grain of aluminum profiles, comprising the following steps: pretreatment, spraying wood grain background color powder, curing, spraying transfer printing powder, recuring, packaging wood grain transfer printing film, vacuuming and coating , thermal transfer curing, the thickness of the sprayed wood grain base color coating is more than 60um, so that when the heat transfer is cured, the wood grain on the transfer film can penetrate into the wood grain base color coating better, improving the The color retention and weather resistance of the coating film and the fidelity of the wood grain texture, and the wood grain mold is used for spraying, the concave and convex three-dimensional effect is strong, and it has a better relief effect, which is closer to the real sense of logs, changing the wood grain on the surface of the aluminum profile without three-dimensional effect Or the current situation of poor three-dimensional effect and insufficient fidelity improves the quality and aesthetic feeling of decorative building materials.

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 w...
