The invention relates to a photocatalyst antibacterial
solid wood composite floor board, and belongs to the field of a functional environment-friendly healthy floor board. The
formaldehyde release limited quantity of the
solid wood composite floor board is smaller than 0.3mg / L; the antibacterial rate of the
solid wood composite floor board is greater than or equal to 90 percent; the surface wear-resistant index of the
solid wood composite floor board is smaller than or equal to 0.08g / 100r; a decoration layer, a wear-resistant primer layer and a photocatalyst antibacterial oil decoration layer are sequentially arranged on a substrate layer; the photocatalyst antibacterial oil decoration layer is a mixture layer consisting of nanoscale TiO2 photocatalyst materials, nanometer silver and UV (
Ultraviolet) scratch-resistant finish paint according to a
mass ratio being (1-2):(0.2-0.4):(15-20); and a balance layer is arranged under the substrate layer. A production process of the photocatalyst antibacterial
solid wood composite floor board comprises the steps of: middle plate tidying, glue mixing, glue application and blank assembling for the first time, cold pressing for the first time, core trimming, glue application and blank assembling for the second time,
hot pressing for the first time, fixed thickness sanding, edge
cutting, puttying,
polishing, sorting, maintenance, glue application and veneering, cold pressing for the third time,
hot pressing for the second time, multi-blade sawing, sanding, two-
end milling, primer application, finish paint mixing and finish paint application. The photocatalyst antibacterial
solid wood composite floor board has the advantages of good antibacterial function, high strength, good wear-resistant performance and foot feeling comfort.
