Description
Technical Field
The invention relates to a preparation technology of a water-based pigment, in particular to an ultralow-viscosity color pigment and a preparation method and application thereof.
Background
When the textile is subjected to ink-jet printing, the coating ink or the pigment ink is sprayed to the surface of the textile through a nozzle of an ink-jet printing device to form a required pattern, so that the special requirements on the properties of the coating ink or the pigment ink are met, such as small particle size, low viscosity, better rheological property, water dilution stability and the like of the coating or the pigment. The main technical content is to improve the color fastness of the coating or pigment and textile products by utilizing the radical polymerization reaction generated by vinyl monomers on fabrics: for example, patent application No. CN201710670752.2 discloses a coating ink comprising water-based inkjet resin and nano printing inkjet ink, wherein the water-based inkjet resin is prepared from methyl methacrylate, N-butyl acrylate, hydroxyethyl acrylate, acrylic acid, styrene, N-hydroxyethyl acrylamide, an emulsifier, sodium bicarbonate and an initiator, and the nano printing inkjet ink comprises carbon black pigment paste of cabot, water-based inkjet resin, glycerol, propylene glycol, diethylene glycol, 1, 2-pentanediol, triethylene glycol monobutyl ether, a surfactant and a bactericide; the ink has more excellent performances than the similar ink, and overcomes the defects of wet rubbing resistance, water washing resistance and the like of the textile direct injection ink. Patent application No. CN202010522728.6 discloses a photo-curing white paint ink formed by adding white paint, acrylate monomer and photoinitiator into polyurethane prepolymer, and the ink is considered to form a pigment-curing film cross-linked structure in the curing process. Not only improves the photopolymerization performance of the ink, but also improves the color fastness of the coating ink. Obviously, unlike the conventional radical-initiated polymerization of vinyl monomers, the fixing polymerization on fabrics does not form a good adhesive, and incomplete or uneven polymerization is easily caused due to the migration of acrylic acid and acrylic ester during the drying process and the difference of polymerization conditions, so that better rubbing color fastness is less likely to be obtained, and pattern colorations are caused by incomplete copolymerization and uneven distribution copolymerization formed on the surface.
