Problems solved by technology

[0006] In recent years, in order to solve the problem of liquid crystal glass adhesion, some customers have chosen to return to the traditional method of spraying the coupling agent in the early stage and heating to solve the adhesion. On the one hand, this will cause VOCs organic volatile pollution problems, on the other hand Requires a lot of cumbersome processes and high product rejection rate

Abstract

The invention discloses electron beam curing ink-jet ink as well as a preparation method and application thereof. The electron beam curing ink-jet ink comprises the following raw materials in parts byweight: 15-35 parts of polyurethane acrylate, 20-35 parts of isobornyl acrylate, 5-10 parts of an organic pigment toner, 0.5-1 part of fumed silica, 5-10 parts of dodecyl methacrylate, 5-20 parts oftri(2-hydroxyethyl)isocyanurate triacrylate, 5-10 parts of tristyrylphenol polyoxyethylene ether methacrylate, 1-5 parts of a dispersing agent and 3-5 parts of an auxiliary agent. According to the invention, 99.99% of high-purity nitrogen is required to fill a reaction container; and then electron beam scanning is adopted to cure ink-jet ink, so that the ink-jet ink forms a color ink layer with high hardness, good film forming toughness, boiling resistance, solvent corrosion resistance, scratch resistance and the like on liquid crystal glass, colorful patterns are formed on the surface of theglass through color combination, and the product attractiveness is improved.

Description

technical field [0001] The invention relates to the technical field of curing new materials, in particular to an electron beam curing inkjet ink and its preparation method and application. Background technique [0002] Electron beam curing (referred to as EB curing) technology is not a new technology in recent years. It belongs to the field of radiation curing just like traditional UV curing. In the early 1970s, Ford of the United States applied EB curing technology to auto parts and instrument coatings for the first time. At home and abroad, the plastics industry uses EB technology to "strengthen" the film fastness by irradiating the film winding end to promote the curing reaction of unsaturated olefins. [0003] However, in the field of ink and printing, EB curing is little known. Theoretically, EB electron beam curing inks and UV ultraviolet curing inks are branches of inks in the field of radiation curing. Since they do not use photoinitiators, the raw materials used a...
