Antiviral antibacterial building materials

摘要

PROBLEM TO BE SOLVED: To provide an antiviral antibacterial building material on which a coating film having excellent antiviral antibacterial activity is formed.SOLUTION: The antiviral antibacterial building material includes a primer layer, an intermediate coating film layer and a surface coating film layer from a base body side which are formed into laminated structure in which the three layers are integrated into one body. The antiviral antibacterial building material exhibits excellent antiviral antibacterial activity for a long period of time by concentrically distributing a 16C or 18C alkyl trimethyl ammonium salt as an active ingredient on the surface of the surface coating film layer thereby enabling the surface coating film layer to have a surface resistivity of 1E+06-1E+13 &OHgr;. The building material is made from various materials such as metal, resin, wood, glass and ceramics and is suitably used as a door knob or a pulling handle of an opening member.
