Abstract

The invention relates to a preparation method of anti-flooding UV optical fiber ink, and provides an optical fiber ink composition capable of being cured under ultraviolet light. The optical fiber ink composition includes an oligomer; an acrylate monomer; a pigment; pigment derivatives, hyperdispersants and initiators; and a polymerization inhibitor. Herein, the oligomer is a mixture of modified epoxy acrylate, urethane acrylate and phosphate modified acrylate, the phosphate modified acrylate is an independently researched and developed oligomer with an efficient wetting function; after the phosphate modified acrylate is matched with the pigment derivative and the hyperdispersant, when 5-15% of the phosphate modified acrylate resin, 0.1-1.5% of the pigment derivatives, and 1-4% of the hyperdispersant are added, the problems of flooding and sedimentation in long-term storage of the UV printing ink are obviously improved.

Description

technical field [0001] The invention belongs to the field of UV (ultraviolet curing) ink preparation, and particularly relates to a preparation method of anti-floating UV optical fiber ink. Background technique [0002] Ultraviolet (UV) curing is a mature and widely used paint curing technology in furniture and building materials, electronic communications, printing and packaging industries. Coatings and inks increase the curing rate of the coating film, and the curing line speed is more prominent in the field of optical fiber coloring. At present, the world's major optical fiber and cable manufacturing companies can reach a speed of 2000m-3000m / min in the fiber coloring link, so the stability of UV fiber optic ink is extremely important. [0003] UV fiber optic ink is a kind of multi-color ink compounded by a variety of pigment pastes. During long-term storage, the pigment paste will basically rise and sink, which will greatly affect the uniformity of optical fiber colorin...
