Abstract

The invention relates to non-formaldehyde fluorescent paint emulsion and a preparation method thereof. The paint emulsion comprises a monomer and the following components in percentage by weight of the monomer: 0.5%-10% of OP-10, 0.5%-10% of sodium dodecyl benzene sulfonate, 0.01%-10% of an initiator, 0.001%-20% of a coloring agent and 20%-500% of water, wherein the monomer is a mixture of 1%-50% of methyl acrylate, 1%-50% of methyl methacrylate, 0-10% of acrylic acid, 0-10% of methacrylic acid and 30%-50% of styrene; an emulsifier is a mixture of OP-10 and sodium dodecyl benzene sulfonate which are equal in mass, and the initiator is azobisisobutyronitrile. The paint disclosed by the invention has excellent fluorescence and rheological property; after being printed with the paint, a textile is bright in color, excellent in softness and good in weather resistance, does not contain components which are harmful to a human body and environment, and has no formaldehyde residue or special smell; non-formaldehyde paint printing of the textile is realized.

Description

technical field [0001] The invention belongs to the field of textile printing assistants, and relates to a formaldehyde-free fluorescent paint emulsion and a preparation method thereof. Background technique [0002] Organic fluorescent pigments, also known as sunlight pigments, absorb light energy under sunlight and do not radiate it in the form of heat energy, but emit the absorbed energy with low-frequency visible light, thus presenting extremely bright colors. There are many preparation methods of fluorescent coatings: the publication number is CN102443340A, and the invention patent application document named as a fluorescent coating and its production method adopts fluorescent powder G5, epoxy resin, alkyd resin, perchloroethylene resin, phthalic acid two Butyl ester, epoxy curing agent, toluene, etc., this kind of paint is mainly used for the indication signs of safe passages and safety doors in public places, and cannot be used for textile printing; the publication num...
