Description

Curing equipment for UV (ultraviolet) skin-sub-paint on surface of plate

Technical Field

The invention relates to curing equipment for UV (ultraviolet) skin sub-paint on the surface of a plate.

Background

The skin-feel board, namely the board coated with the Fuya paint, has good touch and visual effects, and becomes a hot spot applied in the furniture and decoration material industry. Currently, skin feel effects can be generally obtained by the following four processing techniques:

first, film pressing technology

After the UV finishing coat is roll-coated on the board with the primer, the skin-feel finishing coat is pressed by a skin-feel film, and after the UV finishing coat is cured by a UV light source, the film is removed, so that a skin-feel product with film pressure is obtained, as shown in figures 10 and 12.

The film pressing technology can only process plane products; due to the microstructure limitation of the skin-feel film, the aging performance of the skin feel of the product is limited under certain conditions; when in production, the skin-feel film is disposable, which causes higher production cost.

Second, coating technology

Currently, self-drying paint (PU, water-based) is produced by a paint formula, and skin feeling effect can be realized by coating the self-drying paint on a plate, as shown in figures 10 and 12, but the skin feeling effect obtained by the method has short duration and is not resistant to fingerprints.

Curing technology of three-quasi-molecule lamp

IOT corporation from Germany created a 172nm UV curing apparatus (EXCIMER) and has unique properties that can be referred to as the "black technology" of UV curing technology.

Acrylate double bonds in the UV coating formula can generate free radicals after absorbing 172-nanometer ultraviolet light, and a photoinitiator is not needed; the penetration depth of the 172nm ultraviolet is only 100 to 500 nm, so that only one extremely thin layer of the coating on the surface of the plate is cured; polymerization and crosslinking of the cured layer will shrink to form a matte surface and float to the uncured underlying paint, resulting in a matte surface. However, this process needs to be performed under nitrogen atmosphere to make the oxygen concentration in the operation environment lower than 100ppm, and then the conventional UV or electron beam is used to perform the complete curing, as shown in FIG. 11 and FIG. 13. Its advantage is: compared with skin-feel paint such as mould pressing, PU, water-based and the like, the skin-feel product obtained by physical extinction is more resistant to scratch, dirt, fingerprints, repairable and the like. It has the following disadvantages: the one-time investment cost of the equipment is high, the operation cost is high, and only plane products can be processed (if the flatness of a large plate is not enough, defective products can be generated). The standard working life of the 172nm ultraviolet lamp is normal for 3000 hours of 2000-. When the equipment is operated, a large amount of high-purity nitrogen is needed. Normally, the nitrogen gas with the purity of 99.999 percent is required for 20 cubic meters per hour.
