Background
Photocuring refers to the process of curing a monomer, oligomer or polymer matrix under light induction, and is generally used in film forming processes. Photocuring of unsaturated polyester resin; the activation energy generated by the ultraviolet light with the highest energy in the spectrum can break the C-C bond of the unsaturated polyester resin to generate free radicals so as to cure the resin. When the photosensitizer is added into the unsaturated polyester resin, the photosensitizer is initiated by using ultraviolet rays or visible light as energy, so that the resin can quickly generate a crosslinking reaction. The photocuring technology is a photofabrication technology for polymerizing liquid epoxy acrylic resin at a high speed to form a solid state through ultraviolet irradiation with a certain wavelength, and the photocuring reaction is essentially polymerization and crosslinking reaction initiated by light. The photocuring coating is the earliest example of the large-scale successful application of photocuring technology in industry, and is the largest product produced and sold in the photocuring industry at present, the scale is far larger than that of photocuring ink and photocuring adhesive, and epoxy acrylic acid is the main photocuring coating. Compared with the traditional coating and ink, the main advantages of the photo-curing coating and photo-curing ink are environmental protection, because the reactive diluent is adopted to adjust the viscosity, and the content of organic volatile components is extremely low. Non-photocurable coatings or inks are also environmentally friendly, such as water-borne coatings and inks, two-component thermosetting coatings, powder coatings, and the like. The advantages of photocuring techniques over these applications are rapid, low energy consumption. Some application techniques are to combine the photo-curing technique with other techniques, such as photo-curing water-based paint, photo-curing powder paint, to make the advantages thereof more prominent. The existing photocuring device is inconvenient for photocuring the glued paper, and the photocuring treatment efficiency is low.
