The invention discloses an anti-electromagnetic radiation fabric coating adhesive and a preparation method thereof. The anti-electromagnetic radiation fabric coating adhesive is prepared from the following raw materials in parts by weight: 8-10 parts of sodium dodecyl benzene sulfonate, 5-6 parts of fatty alcohol-polyoxyethylene ether, 25-30 parts of butyl acrylate, 85-90 parts of 2-ethylhexyl acrylate, 9-10 parts of cyclohexyl methacrylate, 3.5-4 parts of acrylamide, 4-5 parts of acrylic acid, 1.5-2 parts of trimethylolpropane triacrylate, 10-20 parts of styrene, 1.5-2 parts of glycidyl methacrylate, 1.0-1.6 parts of ammonium persulfate and 250-330 parts of deionized water. The method comprises the following steps: synthesizing an emulsion by emulsification and initiated polymerization; and adding a mixed liquid of 3-6 parts of conductive polyaniline and 15 parts of N,N-dimethyl formamide, 30-35 parts of a carbon nanotube dispersion liquid and 3-4 parts of an associative polyurethane flatting rheological agent, and compounding, so as to obtain the anti-electromagnetic radiation fabric coating adhesive. The anti-electromagnetic radiation fabric coating adhesive is suitable for pure cotton and polyester fabrics, and has good conductive property, anti-electromagnetic radiation property, binding strength, water-fastness, tearing strength, breaking strength, hydrostatic pressure resistance and hand feeling.
