摘　　要：研制了一种以丙烯酸树脂乳液为基料、自制铜粉为导电填料的水性电磁屏蔽涂料,结果表明:当铜粉加入量为65%、漆膜厚度为125μm时,该涂料的表面电阻率为0.04?/cm2,在200 kHz～300 GHz频段范围内的电磁屏蔽效能最低为71 db.A water-borne electromagnetic shielding paint based on a kind of acrylic resin emulsion with self-made copper power as conductive filler was developed.Experiment results show that when the copper powder addition is 65% and the thickness of the paint film is 125 μm,the surface resistivity is 0.04 Ω/cm^2 and the minimum efficacy of the electron electromagnetic within 200 kHz～ 300 GHz is 71 db.
