Abstract

The invention discloses a thermal transfer printing manufacturing process for high-quality environmental-friendly aluminum alloy wood grain profiles, which comprises the following steps: S1, preparing the aluminum alloy profiles; S2, preparing a surface base film coating on the surface of the aluminum alloy profiles, using Any one of powder spraying method, fluorocarbon spraying method and electrophoretic coating method; S3. Wrap paper or plastic film on the outside of the aluminum alloy profile with base film coating, and the inner surface of the paper or plastic film is pre-attached with heat Transfer ink, thermal transfer ink is made up of a mixture of pigment action layers, ink additives and binders; S4. Put a vacuum plastic bag on the outside of the paper or plastic film, and vacuumize the paper or plastic film to stick it flat on the aluminum profile After vacuuming, the whole is sent to the thermal transfer furnace, and the temperature of the thermal transfer furnace is set to 190~200℃. After transferring for 14~15min, the aluminum alloy wood grain profile with good quality is finally obtained. The beneficial effects of the invention are as follows: the process is simple, the prepared aluminum alloy wood grain profile has large binding force and long service life.

Description

technical field [0001] The invention relates to a thermal transfer printing manufacturing process of a high-quality environment-friendly aluminum alloy wood-grain profile. Background technique [0002] Green and environmentally friendly aluminum alloy surface wood-grain profiles that can replace natural wood resources, its application range is becoming wider and wider, and its consumption is increasing. It has been widely used in construction, indoor door frames, and various cabinets, such as bookcases, wine cabinets, and wardrobes. , Shoe cabinets, lockers, tables and chairs, wooden-like aluminum alloy ladders, various frames, decorative panels, threads, profiled materials, antique carvings and other wood-like products on the surface. The existing preparation process of aluminum alloy wood-grain profiles adopts electrophoretic painting process. Electrophoretic painting is to anodize the aluminum alloy base material to form dense micro-pores with a depth of about 10um. Part...
