Abstract

The invention belongs to the field of special coatings, and discloses a composite nanometer inorganic antibacterial agent. The composite nanometer inorganic antibacterial agent comprises the followingcomponents by weight: 12.6 to 15.75 parts of nanometer silver, 20 to 25 parts of zinc oxide, 15 to 20 parts of aluminium oxide, 10 to 20 parts of titanium dioxide, 10 to 20 parts of silicon dioxide,5 to 7 parts of organic bentonite and 15 to 20 parts of water. The composite nanometer inorganic antibacterial agent provided by the invention has the advantages of greenness, environmental protection, long-lasting antibacterial function, etc., is easy for mixing and processing, and solves the process problems of easy sedimentation, easy discoloration and easy agglomeration in the production and processing processes of ordinary inorganic antibacterial agents at the same time. Meanwhile, the invention also discloses a nanometer antibacterial waterborne wood lacquer antifreeze topcoat. The nanometer antibacterial waterborne wood lacquer antifreeze topcoat provided by the invention has the above-mentioned advantages, and also has the advantages of good fullness, good paint film hardness, goodyellowing resistance and thermal stability and excellent wear resistance.
