Abstract

The invention provides a preparation method of aqueous daylight fluorescent pigment color paste and relates to the technical field of preparing water-dispersibility daylight fluorescent pigment color paste. The aqueous daylight fluorescent pigment color paste comprises the following steps: preparing a disperse system, preparing of pre-emulsion, reacting, and adding an oxidative-reductive initiated system to react to obtain the aqueous daylight fluorescent pigment color paste. The aqueous daylight fluorescent pigment color paste prepared by the method disclosed by the invention is bright in color, has the excellent color paste hiding rate without color expanding and leaking effects, and further has long-term storage stability.

Description

technical field [0001] The invention relates to the technical field of preparation of water-dispersed sunlight fluorescent pigment paste. Background technique [0002] Daylight fluorescent pigment resin is a new type of coloring material that combines pigments and dyes. Under the irradiation of ultraviolet light, they not only selectively absorb and reflect natural light like ordinary pigments, but also absorb high-frequency and short-wave light, and can pass through electrons. The energy level jumps, and the light energy converted into low-frequency and long-wave is released, and its brightness is several times higher than that of traditional ordinary pigments, which can quickly catch people's sight. [0003] When it is used in textile printing and dyeing, on the basis of printing process optimization and polymer-based material optimization, some of the sunlight fluorescent pigment resins are applied to the pigment printing of cotton fabrics after sizing, and some products ...
