Abstract
The invention provides flame-retardant UV-LED coating gloss oil and a preparation method thereof. The flame-retardant UV-LED coating gloss oil comprises 20-25 parts of polyester acrylic resin, 10-15 parts of epoxy acrylic resin, 40-45 parts of a reactive diluent, 5-10 parts of a photoinitiator, 5-10 parts of tannic acid modified nano graphene, 3-4 parts of a filler and 1-2 parts of an auxiliary agent. Polyester acrylic resin and epoxy acrylic resin are blended to serve as a gloss oil prepolymer, tannic acid modified nano graphene is added as a modifier, the modifier is mixed with a monomer and the prepolymer in gloss oil, then polymerization is conducted to obtain a nano composite material, a synergistic flame-retardant composite filler is provided, the flame retardant property of the composite filler can be greatly improved, the prepared UV-LED coating gloss oil has good flame retardant effect, excellent flexibility and adhesive force, good printing adaptability and the like, and the technical problem that the same type of coating gloss oil in China at present cannot resist flame is solved.
Description
technical field [0001] The invention belongs to the technical field of UV-LED inks, and in particular relates to a flame-retardant UV-LED coating varnish and a preparation method thereof. Background technique [0002] In order to improve the quality of the current building materials and furniture products, it is often necessary to apply or print a layer of protective coating or varnish after preparation, which can not only prevent water and dust, but also improve the grade of the product. [0003] However, the current UV-LED coating varnish components contain a large amount of organic compounds, which will accelerate the combustion of the flame and release a large amount of harmful gases when a fire occurs. These existing problems are completely inconsistent with the environmental protection and safety required by the furniture and building materials industry, which greatly limits its application in furniture and building materials products. Therefore urgently need further ...
