The present invention discloses a kind of preparation method of nanometer ferroferric oxide modification water-and acrylate magnetic pressure sensitive adhesive, comprises the steps of：（1）Nano ferriferrous oxide granule is weighed to be added in the mixed solution of second alcohol and water, it is ultrasonically treated after, by silane coupler modified, obtain it is silane coupler modified after ferriferrous oxide particles；（2）After by the aqueous solution ultrasonic disperse of modified ferriferrous oxide particles, NaHCO is added to 3 In solution；NPE ammonium sulfate, deionized water, butyl acrylate, methyl methacrylate, hydroxy-ethyl acrylate, acrylic acid are mixed to get pre-emulsification emulsion, by pre-emulsification solution, initiator and the NaHCO of ferroso-ferric oxide is mixed with 3 Solution reaction, that is, obtain nanometer ferroferric oxide modification water-and acrylate magnetic pressure sensitive adhesive.The method that the present invention is provided, nano ferriferrous oxide is good with acrylic acid ester emulsion compatibility, and the magnetic pressure sensitive adhesive heat endurance for obtaining is good, and caking property is good. |
