Processing technique for obtaining embossment type wood grain surface of aluminum profile

Abstract

The invention discloses a processing technique for obtaining an embossment type wood grain surface of an aluminum profile. The processing technique includes the following steps of pre-processing, wood grain ground color powder spraying, solidifying, transfer powder spraying, secondary solidifying, wooden transfer film packaging, laminating in a vacuumizing mode and heat transfer printing solidifying. A wood grain ground color coating is sprayed by more than 60 [u]m, so that wood grains on a transfer film better permeate into the wood grain ground color coating in heat transfer printing solidifying. The color keeping performance and weather resistance of the coating are improved, and the fidelity of wood grain texture is improved. Moreover, a wood grain mold is used for spraying, a concave-convex stereoscopic impression is strong, a good embossment effect is achieved, a realistic log feeling is better achieved, the problems that the wood grains on the surface of the aluminum profile have no stereoscopic impression or have a poor stereoscopic impression, and the fidelity is insufficient are solved, and the quality and aesthetic feeling of decorative building materials 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 w...
