The light curing resin light source structure is applied to the field of color art printing, in particular, the photocurable resin matched can obtain a smooth photoreactive curing resin product, and has the advantages of reducing solvent usage, stabilizing process and increasing process line speed. efficacy.

People's awareness of environmental protection is on the rise. Countries around the world have tightened environmental regulations to protect the national environment. For the manufacturing industry, it is required to reduce emissions of waste gas and waste water. Printing, textiles, electronics, etc. often use resin for letterpress or gravure coating, and resin materials. From the development of early oil-soluble solvent resins to water-based resins, water-based resins require high energy consumption for baking energy, so photo-curable resins have been attracting attention and development in recent years. The photocurable resin contains a photoinitiator having a specific ultraviolet light absorption wavelength, and the resin is irradiated with a specific ultraviolet light source to cause a photochemical reaction of the chemical structure in the resin, and the photocurable resin is molded into a finished product. The photocurable resin can complete the photochemical reaction in a short time, but in order to improve the quality yield of the cured product in practice, it is often necessary to add an auxiliary agent to improve the flow stability of the photocurable resin before the photochemical reaction. The solvent or leveling agent is not involved in the photochemical reaction of the photocurable resin, so that the photocurable resin often exhibits surface curing but the inner layer is still uncured "dry". The reduction of the amount of solvent or leveling agent added to the photocurable resin has become the subject of joint discussion between the resin raw material industry and the photocuring equipment industry. In the field of traditional color art printing, the medium and long wave infrared tunnel furnace is used to accelerate the drying of the ink. Because the medium and long wave infrared rays solidify the surface of the ink, there is a problem of poor drying on the bottom layer of the ink. Therefore, after drying, the drying tray is placed for a while. The next color ink is printed, which causes time-consuming shortcomings.

The prior art is directed to the switching of the source of the infrared light and the ultraviolet light. As disclosed in Chinese Patent Publication No. CN101813296, an LED light source having a cut-off ultraviolet and infrared dual function filter is used, and the filter has a dual function of cutting off ultraviolet rays and infrared rays. The transparent substrate is coated with an ultraviolet cut-off film layer and an infrared cut-off film layer; it can absorb light having a short wavelength range of less than 445 nm and a long wavelength range of wavelength greater than 700 nm. The prior art is directed to wavelength-adjustable blue or ultraviolet illuminating light sources. As disclosed in Chinese Patent Publication No. CN105870304A, a wavelength-tunable LED light source includes an excitation light source, a wavelength conversion component, and a wavelength optimization component; the wavelength conversion component is a phosphor powder and a transparent component. Material blending preparation, including fluorescent glass coating wavelength conversion component, fluorescent resin coating wavelength conversion component, fluorescent resin wavelength conversion component, or fluorescent powder lens wavelength conversion component; the basic shape of the wavelength conversion component is a light transmitting plate or Convex panel. The prior art is directed to a near-infrared light medical diagnosis and treatment light source, as disclosed in Chinese Patent Publication No. CN105932140A, a near-infrared wavelength LED light source comprising an excitation light source, a wavelength conversion component and a wavelength optimization component; the excitation light source is a visible light source or a near-infrared light source; A light source capable of emitting light of any particular wavelength in the near-infrared wavelength range has long life and stability, and has considerable power, especially for medical and cosmetic applications.

The prior art is directed to a process for the application of near-infrared light to resin drying, as disclosed in the Republic of China Patent Publication No. TWI579060B, a method and apparatus for drying a metal coating layer for a transparent substrate, comprising: a coated metal a thin transparent substrate of the paint layer, the thin transparent substrate is driven by a roll-to-roll drive or batch-fixed in a drying zone of the drying device, and the drying zone maintains a certain distance from the near-infrared light source of the drying device The near-infrared light source performs a drying operation on the thin transparent substrate with a specific light source energy. Then, in the drying operation, the thin transparent substrate is statically fixed to the drying zone or the dynamic drying operation. Finally, after the thin transparent substrate is dried, it is transferred to the cooling stabilization zone for natural cooling.

The creator of this creation has been working in the reactive resin materials and equipment industry for many years. He is well aware of the general photopolymer, which consists of a polymer monomer and a prepolymer. It is generally liquid and contains a photoinitiator (photosensitive). The agent, after a certain wavelength of ultraviolet light (such as a wavelength of 250 ~ 300 nm), initiates polymerization to complete the curing. The photocurable resin of the existing process still has the shortcomings of the surface dry phenomenon, and the photocurable light source module of the photocurable resin still has a limited wavelength range. The creator has found through experiments that in order to solve the problem of poor drying and time consuming of the underlying layer of the photocurable resin (such as ink application), the near-infrared/short-wave infrared wavelength is selected, and the wavelength has a high depth of the light-transferring resin to allow the light to be cured. Resin drying is more complete, improving the problem of poor drying; also with infrared (including near infrared / short wave / medium wave infrared) can help the temperature of the photocurable resin, when using solvent-free photocurable resin, the design uses infrared to increase the temperature of the photocurable resin, Achieve leveling effect, and increase the wettability of the surface of the coated resin to enhance the adhesion; or it can be supplemented by infrared light source to help provide penetration heat, when the photocurable resin is heated from the inside to the outside.
