Abstract

The invention discloses a heat-resistant yellow-stain-resistant epoxy acrylate low polymer and a preparation method of UV (ultraviolet) ink. The heat-resistant yellow-stain-resistant epoxy acrylate low polymer is prepared through a following method comprising the following steps of carrying out an addition-esterification reaction on triglycidyl isocyanurate and an acrylic organic acid under the action of a catalyst, so as to obtain triglycidyl isocyanurate acrylate, then reacting the triglycidyl isocyanurate acrylate with an acid anhydride to obtain an acid anhydride modified triglycidyl isocyanurate acrylate, finally, adding a viscosity reducer and a reactive thinning agent into the acid anhydride modified triglycidyl isocyanurate acrylate, and regulating system viscosity to obtain the heat-resistant yellow-stain-resistant epoxy acrylate low polymer. The heat-resistant yellow-stain-resistant epoxy acrylate low polymer is adopted for the UV ink prepared by the invention; the defect that conventional UV ink is easy to yellow is overcome; moreover the UV ink is high in adhesive force, is wide in the serviceable range to base materials, and can be printed on the upper surfaces of base materials of PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), glass, a circuit board and the like in a screen printing manner. The UV ink prepared by the invention has high glossiness, excellent heat resistance and yellow stain resistance, and is further wide in application range.

Description

technical field [0001] The invention relates to the field of inks, in particular to the synthesis of a heat-resistant and yellowing-resistant epoxy acrylate oligomer and its application in UV inks. Background technique [0002] Ultraviolet (UV) curing means that under the action of ultraviolet light, the photosensitive substances in the system undergo chemical reactions to produce active fragments, which trigger the polymerization and crosslinking of active monomers or oligomers in the system, so that the system has a liquid coating instantly into a solid coating. Since Bayer in Germany developed the first generation of UV curing coatings in 1967, UV curing technology has developed rapidly worldwide, mainly because it cures quickly and meets the needs of modern automatic production; it is non-polluting and complies with the requirements of modern coatings and inks. Development direction; high coating film quality, high hardness, scratch resistance, corrosion resistance and ...
