The invention discloses a surface treatment process for
solid wood floor. The surface treatment process comprises the following steps: I,
coating a
tannic acid solution on the surface of a plain panel; II, carrying out
infrared drying on the floor; III,
coating a
ferric trichloride solution on the surface of the floor; IV, performing
surface chemical reaction on the floor to balance; V,
coating dust paint on the surface of the floor; VI, carrying out
infrared drying on the floor and carrying out mechanical
polishing on the surface of the floor; VII, coating the surface of the floor with a H2O2 solution; VIII, reacting and balancing the floor; IX, mechanically
polishing the surface of the floor; and X, carrying out paint
UV coating on the surface of the floor. According to the surface treatment process disclosed by the invention, a proper chemical
reagent and a proper wood internal
tannic acid component are selected to react with the
surface coating tannic acid component, so that surface color-changing treatment is carried out on a
solid floor product, and formed color is more natural from inside to outside, an archaistic age feeling is reflected better, and demands of consumers can be met to a greater extent.
