Description

A kind of formaldehydeless fluorescent coating emulsion and preparation method thereof

Technical field

The invention belongs to textile printing auxiliary agent field, relate to a kind of formaldehydeless fluorescent coating emulsion and preparation method thereof.

Background technology

Organic fluorescent pigment also claims a day delustering pigment, under sun exposure, absorbs luminous energy, with the form of heat energy, does not distribute, and with low frequency visible ray, the energy being absorbed is launched, thereby present abnormal bright colour.The preparation method of fluorescent coating is more: publication number is CN102443340A, the application for a patent for invention file that name is called a kind of fluorescent coating and making method adopts fluorescent material G5, epoxy resin, Synolac, supervinyi chloride resin, dibutyl phthalate, epoxy hardener, toluene etc. to make, this type of coating is mainly used in the Warning Mark of escape way, relief door of public place etc., can not be for textile printing; Publication number is CN101643601A, the application for a patent for invention file that name is called aqueous orange fluorescent paint adopts color spreading agent, pigment, dispersion agent, thickening material, defoamer, mould inhibitor, anti-settling agent, glycol auxiliary agent, water etc. to prepare aqueous fluorescent coating, but particle diameter is larger, be not suitable for the printing technology of textiles.

Formaldehyde release And Spread of Solute in textiles is subject to denouncing of people day by day, and particularly in recent years, the harm problem of formaldehyde has obtained the extensive concern of home and abroad environment protection and industry member, and various countries also formulate rule and standard in succession, and PARA FORMALDEHYDE PRILLS(91,95) content is made strict restriction.The current PARA FORMALDEHYDE PRILLS(91,95) of European Union is not also released unified restriction rules, but as German, French, Dutch etc., has some rules to limit the use in textiless in the major country of some European Union.The mandatory GB GB 18401-2003 of China also proposes strict restriction to the formaldehyde in textiles.At present when preparing fluorescent coating, generally adopt and first fluorescence dye is dispersed in the mixture of para toluene sulfonamide, formaldehyde resin and melamine resin, make the solid fluorescence pigment of powdery, then the solid fluorescence pigment and resin of powdery is mixed and made into fluorescent coating.When pigment printing, by a kind of synthetic resins that can generate strong film of stamp tamanori, fluorescent coating is anchored to the surface of fabric.If publication number is CN102796512A, it is raw material that the patent application document that name is called a kind of preparation method of melamine formaldehyde resin fluorescent microsphere utilizes trimeric cyanamide, formaldehyde, prepares carbamide solubility prepolymer; Fluorescence dye is added in the pre-polymer solution making, dye molecule adsorbs and is wrapped in the prepolymer molecule of cladodification; By heating make in prepolymer generation molecule, intermolecular further polycondensation, obtain single dispersion, particle diameter is controlled, can wrap up the fluorescent microsphere of multiple fluorescence dye; There is bibliographical information, fluorescence dye is scattered in the terpolycyantoamino-formaldehyde resin of para toluene sulfonamide modification and makes fluorescent pigment latex, at 40～50 ℃ of temperature, directly mix with water white polyacrylic resin emulsification and make fluorescent coating (< < Sichuan Teachers University journal (natural science edition) > > 2001,02).Above stamp is raw material with all using formaldehyde in fluorescent coating preparation process, has neither part nor lot in discharging that the free formaldehyde of polymerization can continue after stamp completes, and affects people's health.Therefore, synthetic a kind of fluorescent coating that can substitute toluol sulfonamide, formaldehyde resin and melamine resin completely becomes the new trend of pigment printing.
