る。That is, the present invention is characterized in that when a solution copolymerization of a fluorine acrylate resin component, an acrylic polyol resin component and / or a silicone polyol resin component is carried out as a urethane ester, a fine ceramic powder is added together with an antibacterial component. The present invention relates to a fluororesin-based coating agent and a method for producing the same. As the fluorine acrylate used in the present invention, Asahi Glass AG650, Meisei Chemical LS-520, Sumitomo 3M FC721, etc. are used, and Sumitomo Bayer Desmophen as an acrylic polyol. Examples include RD181 and Desmophen A450, silicone polyols such as KR9706 manufactured by Shin-Etsu Chemical, and examples of aromatic fluorine components include A700X manufactured by Central Glass. As the solvent, a mixed solvent of diacetone alcohol, cellosolve acetate, methyl cellosolve, toluene and the like is used in approximately the same amount as these resin components, and the total amount of the antibacterial component and the ceramic component is also approximately the same amount. The antibacterial component used in the present invention is particularly preferably a combination of calfa AP obtained from citrus seeds, particularly grapefruit seeds, and a shale-based powder as a ceramic fine powder, which has an antibacterial effect due to an organic antibacterial component. It is considered that carbonaceous components such as graphite exhibit similar effects), and are reinforced by the heat retention effect and antibacterial effect. A small amount of cobalt naphthenate or ethylene bromide is used as a polymerization catalyst. These polymerization catalysts also have a function as a curing agent with an addition amount of 2% or more, but as other curing agents, polyisocyanate (Sumidule, Coronet, etc.) is used, and if necessary, a viscosity adjusting agent, a spreading leveling agent, etc. are used.
