4D weather-resistant ancient wood grain processing technology

Abstract

The invention discloses a 4D weather-resistant ancient wood grain processing technology. The technology includes the following steps of blank inspection, material racking and punching, material sorting performed according to models, pretreatment, low-temperature drying, bottom powder electrostatic spraying, low-temperature semi-curing, first inspection of the film thickness of a coating going out of a furnace, first time of surface powder electrostatic spraying, fine wood grain forming, low-temperature semi-curing, second time of inspection of the film thickness of the coating going out of the furnace, second time of surface powder electrostatic spraying, large grain forming, low-temperature curing, inspection of a product going out of the furnace, discharging, secondary inspection, packaging frame package, the operation that the product is transferred into a wood grain workshop, panel testing, color confirmation, furnace temperature adjustment, paper unfolding performed according to models, paper wrapping, packaging of high-temperature bags, the operation that the product is placed on a machine, vacuumizing, the operation that the product enters a transfer printing furnace to be baked at a high temperature, the operation that the product goes out of the furnace to be discharged out of the machine, bag detachment, paper tearing, the operation that the product returns to the furnace to be glared, inspection of a finished product going out of the furnace, film pasting, shrinkage film sleeving, the operation that the product passes a shrinkage film machine to be tightened, approval certification pasting and the operation that the product is put in a warehouse. The surfaces of wood grains processed through the 4D weather-resistant ancient wood grain processing technology are free of particles, the coating is uniform, weather resistance is good, and color fading, gloss loss and delustering do not happen to the wood grains even if the wood grains are used outdoors for 15 years or above.

Description

technical field [0001] The invention belongs to the technical field of surface coating of aluminum profiles, and in particular relates to a 4D weather-resistant ancient wood grain processing technology. Background technique [0002] The wood-grained coloring process of aluminum profiles is the development of the conventional coloring technology. The aluminum profiles that have been colored by wood-graining have a strong sense of wood, and the doors, windows, furniture, and office supplies made of it match the wooden structure. At present, there are two main methods of wood grain treatment on the surface of aluminum materials in China. One is thermal transfer printing technology, which is characterized by clear and lifelike wood grain, and can transfer various wood grain patterns, but the production cost is high and the process is complicated. The other is the vertical secondary spraying and sweeping technology, which has a strong three-dimensional effect and low production c...

Problems solved by technology

At present, there are two main methods of wood grain treatment on the surface of aluminum materials in China. One is heat transfer printing technology, which is characterized by clear and lifelike wood grain, and can transfer various wood grain patterns, but the production cost is high and the process is complicated.

The other is the vertical secondary spraying and sweeping technology, which has a strong three-dimensional effect and low production cost, but the wood grain pattern is abstract and single, and the flatness is not enough

Its surface effect is uneven, and it is prone to fading, fading and matting, and has poor weather resistance
