Abstract

The invention belongs to the technical field of materials, and particularly relates to a weak solvent ink absorption flame retardant coating and a preparation method thereof. The coating is prepared from the following raw materials in parts by weight: 1 to 7 parts of acrylic acid, 1 to 8 parts of methacrylic acid, 3 to 20 parts of dodecyl methacrylate, 3 to 50 parts of methyl acrylate, 3 to 40 parts of ethyl acrylate, 3 to 50 parts of butyl acrylate, 10 to 70 parts of methyl methacrylate, 3 to 50 parts of butyl methacrylate, 0.2 to 0.6 part of an initiator, 1 to 5 parts of an emulsifier, 1 to4 parts of a leveling agent, 1 to 2 parts of a thickener, 1 to 30 parts of silicon dioxide and 1 to 30 parts of a composite flame retardant. The surface of the coating prepared according to the preparation method is flat, bubble-free, crack-free, good in water resisting effect, high in printing quality, high in flame retardancy, and particularly extremely excellent in ink absorption rate.

Description

Technical field [0001] The invention belongs to the technical field of materials, and particularly relates to a weak solvent ink absorbing flame-retardant coating and a preparation method thereof. Background technique [0002] Inkjet inks are roughly divided into water-based inks and solvent-based inks according to the composition of the solvent; water-based inks are pollution-free, but the main components evaporate slowly, are not easy to dry, and the screen has poor weather resistance. They are mainly used indoors; solvent-based inks have strong weather resistance and are adaptable outdoor. Traditional solvent-based inks are generally ester and ketone organic solvents that evaporate quickly, which can meet the requirements of fast printing. However, the high concentration of volatile organic solvent in the printing room is more harmful to indoor personnel. Based on the above reasons, eco-solvent inks were born in compliance. Eco-solvent ink is also called environmentally fri...
