Method for curing UV skin sub-paint on surface of plate

Abstract

The invention relates to a method for curing UV (ultraviolet) skin sub-paint on the surface of a plate. A curing device comprises a machine frame, an input conveying belt structure, a middle conveyingroller structure, an output conveying belt structure and an LED (light-emitting diode) curing lamp; and the curing device is characterized by further comprising one or more upper skin sub-lamp sets and two or more lower skin sub-lamp sets, the power of each skin sub-lamp in the upper skin sub-lamp sets and the power of each skin sub-lamp in the lower skin sub-lamp sets are less than 500 W, the wavelength of each skin sub-lamp in the lower skin sub-lamp sets is 200 nm-320 nm, and conveying rollers are located between the upper skin sub-lamp sets and the lower skin sub-lamp sets. The curing method comprises the steps of LED curing of the UV skin sub-paint on the surface of the plate, special curing of the UV skin sub-paint on the surface of the plate and final curing of the UV skin sub-paint on the surface of the plate. The method has the advantages that not only is the skin feeling effect of an ultra-matte layer achieved on the plane plate, but also the skin feeling effect of the UV skin sub-paint can also be achieved on the plate with a special-shaped face, the consumption is reduced, a traditional coating process is simplified, and the skin feeling effect of the ultra-matte layergenerated by excimer lamp curing technology can be achieved.

Description

technical field [0001] The invention relates to a method for curing UV skin paint on the surface of boards. Background technique [0002] Since the skin-feeling board is a board coated with furya paint, it has good tactile and visual effects, and has become a hot spot in the furniture and decoration materials industry. At present, the skin feeling effect can generally be obtained by the following four processing techniques: [0003] 1. Membrane pressure technology [0004] On the plate with primer, after roller coating UV topcoat, then use skin-feeling film to flatten the skin-feeling topcoat, after curing by UV light source, peel off the film to obtain film-pressed skin-feeling products, such as Figure 10 and Figure 12 shown. [0005] Membrane pressure technology can only process flat products; due to the limitation of the microstructure of the skin sensory film, the timeliness of this kind of product will be limited under certain conditions; the skin sensory film is d...

Problems solved by technology

Its disadvantages: the one-time investment cost of the equipment is high, the operating cost is high, and only flat products can be processed (if the flatness of the large plate is not enough, there will be defective products)

The standard working life of 172nm UV lamp is 2000-3000 hours, and it is easy to be damaged due to improper maintenance. The price of an imported light source is about 70,000 RMB (different brands will vary)
