The oligomer is a mixture of modified epoxy acrylate, polyurethane acrylate and phosphate modified acrylate, wherein the phosphate modified acrylate is independently developed oligomer with a high-efficiency wetting function, and is matched with a pigment derivative and a hyperdispersant, and when 5-15% of the phosphate modified acrylate resin, 0.1-1.5% of the pigment derivative and 1-4% of the hyperdispersant are added, the problems of flooding and sedimentation of the UV ink in long-term storage are obviously improved.
Description
Technical Field
The invention belongs to the field of UV (ultraviolet light curing) ink preparation, and particularly relates to a preparation method of anti-flooding UV optical fiber ink.
Background
Ultraviolet (UV) curing is a mature coating curing technology widely applied to industries such as furniture building materials, electronic communication, printing and packaging, and the like, and utilizes the principle that mercury vapor is excited to emit characteristic ultraviolet (200-400nm) to be matched with corresponding UV coating and printing ink to improve the curing rate of a coating, wherein the coloring field of the optical fiber coloring field is more prominent in curing linear velocity. At present, the speed of the optical fiber coloring link of the main optical fiber and optical cable manufacturing company in the world can reach the winding and unwinding speed of 2000-3000 m/min, so the stability of the UV optical fiber ink is very important.
The UV optical fiber ink is a multi-color ink compounded by a plurality of pigment color pastes, and basically has the phenomenon that the pigment color paste floats upwards and sinks in long-term storage, and the phenomenon can greatly influence the uniformity and the coloring strength of optical fiber coloring.
In order to solve the problem of unstable optical fiber coloring quality caused by the floating or sinking of the pigment slurry, various optical fiber and cable manufacturing companies perform a pretreatment process before using the UV optical fiber ink. The pretreatment process is usually at a rotating speed of 6-15 r/min, and the optical fiber is rolled and shaken at a constant speed for at least 8h, so that the unstable coloring quality of the optical fiber is improved to a certain extent, but redundant and tedious work and other hidden troubles are brought to production.
According to Chinese patent CN101225188.X found in the published materials, the environmental-friendly PVC anti-flooding artificial leather color paste and the preparation method thereof (New Material science and technology Co., Ltd. of Fujian Baolite, patent) can achieve the effect that no abnormal quality such as flooding, layering color stripes and the like can be generated during the production of the artificial leather production line by applying the functional auxiliary agent.
Although anti-flooding artificial leather color paste exists, the artificial leather color paste is not a product specially developed based on a UV curing system and is not suitable for a UV optical fiber coloring process with high linear speed. The invention is based on the fact that the novel phosphate ester modified acrylate is utilized to improve the wettability to the pigment, the anchor group adsorption and affinity effects of specific pigment derivatives are combined, and finally, the whole UV optical fiber ink system is kept stable through the special spatial structure of the hyper-dispersant, so that the UV optical fiber ink does not have the defects of flooding and sedimentation in long-term storage.
