A device for making ultra-dumb skin-feeling boards with lamps

Abstract

The invention belongs to the technical field of photocuring, and particularly relates to a device for lamp manufacturing of a super-matte skin feeling plate. The device comprises a gallium lamp box, an xenon lamp box and a mercury lamp box which are arranged in sequence in the conveying direction of the plate, a conveying belt used for conveying the plate is arranged among the three lamp boxes, meanwhile, a seal space used for containing the plate which is conveyed in place through the conveying belt is further included, an oxygen displacement device is arranged in the xenon lamp box, and ultraviolent light with the wavelength being 172 nm is generated in the oxygen displacement device. A 172 nm quasimolecule xenon lamp is adopted for radiating a UV coating, due to the limited penetratingcapacity of the ultraviolet light at the wave segment, a coating with the thickness about 0.1 micrometer on the surface of the coating is subjected to photocuring, the coating with the larger thickness is still in a liquid state, therefore, the photocured surface layer coating can generate uniform wrinkles due to the shrinkage reason, the microcosmic concave and convex surface can be generated, the matte skin feeling effect is achieved, the defect that extinction powder cannot achieve the super-matte skin feeling is overcome, and extinction powder is not needed.

Description

technical field [0001] The invention belongs to the field of photocuring technology, and in particular relates to a device for making ultra-dull skin-feeling boards by lamps. Background technique [0002] At present, there is no 172nm excimer lamp system in my country for the production of ultra-dumb skin-feeling panels. It is now widely used in the coating of wooden panels to achieve ultra-dumbness by adding matting powder fillers to UV coatings. This method has the following defects: [0003] 1. In order to achieve an ultra-dumb effect, a large amount of matting powder is required. The matte effect of the surface obtained by adding fillers is due to the matte effect achieved by the protrusions formed by the fillers in the coating to scatter the light. , irregular uneven, feel uncomfortable. The surface obtained by curing with a 172nm lamp has a matte effect because the wrinkles on the entire surface scatter the light. The matte finish will be more even and the surface wi...

Problems solved by technology

[0004] 2. The matting powder is a nano-scale ultrafine powder, which will generate flying dust when used, which will cause great damage to the respiratory tract

[0005] 3. The matting powder has thickening and thixotropy, and the viscosity of the coating is not easy to control

[0006] 4. The matting powder is a nano-scale ultrafine powder, with little thickening and thixotropy, and a good matting effect needs to be imported, which is expensive
