    • Disclosed is an electromagnetic wave-shielding coating material which is superior in both paintability and a electromagnetic wave shielding activity. Also, the coating material is of antistatic activity. The coating material comprises polyaniline (ES) with a solid content of 1-50%, a matrix polymer with a solid content of 1-50%, and additives at a predetermined amount. Also disclosed is an electromagnetic wave-shielding coating material, which is prepared by mixing polyaniline (ES, 100%), an acrylic resin and additives at predetermined amounts and adding the mixture with a hardener and a mixed solvent at predetermined amounts just before use. The electromagnetic-shielding coating material is able to effectively shield electromagnetic waves with a broad band of frequencies and be coated onto cases of various electromagnetic apparatuses, thereby protecting the body from electromagnetic wave pollutions.
    • 公开了一种电磁波屏蔽涂层材料,其涂漆性和电磁波屏蔽活性均优异。 此外,涂料具有抗静电活性。 涂层材料包括固体含量为1-50%的聚苯胺(ES),固体含量为1-50%的基质聚合物和预定量的添加剂。 还公开了一种电磁波屏蔽涂层材料,其通过以预定量混合聚苯胺(ES,100%),丙烯酸树脂和添加剂并且在使用前以预定量与固化剂和混合溶剂混合来制备。 电磁屏蔽涂层材料能够有效地屏蔽具有宽带频率的电磁波并涂覆在各种电磁装置的外壳上,从而保护身体免受电磁波污染。
