  • Patent number: 6756123
    Abstract: Disclosed is an anticorrosion paint for preventing steel materials from corrosion by using polyaniline as an anticorrosion pigment. The anticorrosion paint has an excellent anticorrosion effect, long persistence of the anticorrosion effect, high durability and superior coating property controlling the anticorrosion effect, without using metal causing environmental pollution as an anticorrosion pigment. Especially, in the anticorrosion paint, the top coat paint for improving the protection of the primer coat paint and the anticorrosion effect. The top coat paint includes 40 to 89 wt % of matrix resin, 5 to 54 wt % of colored pigment, 1 to 50 wt % of dopants and 5 to 54 wt % of mixed solvents, and the primer coat paint includes 3 to 49 wt % of the polyaniline, 40 to 86 wt % of the matrix resin, 1 to 47 wt % of the dopants and 10 to 56 wt % of the mixed solvents. The anticorrosion paint plays a role in exerting persistently the excellent anticorrosion effect without causing environmental problem.

  • Patent number: 6548196
    Abstract: Wallpaper for shielding electromagnetic waves, which can effectively shield wideband frequency electromagnetic waves and prevent static electricity, is provided. The wallpaper is prepared by applying and coating onto at least one surface of raw paper a coating composition comprising, mixed in a predetermined ratio based on the total weight of the composition, 1 to 69% by weight of at least one material selected from the group consisting of a conductive polymer material with about 1% to about 100% solids by weight of the conductive polymer material, conductive carbon and graphite, 30 to 98% by weight of matrix polymer with about 1% to about 50% solids by weight of the matrix polymer, 0 to 59% by weight of a solvent and 1 to 40% by weight of additives. Also, in order to form a protection layer for protecting the electromagnetic wave shielding layer and to enhance commodity attraction, a patterned layer is further formed and the resulting structure is dried.
