The invention discloses wood
lacquer for purifying
formaldehyde and a preparation method thereof. The wood
lacquer is prepared by mixing a component A with a component B in a
mass ratio of (1:0.25)-(1:0.5), and then stirring the mixture uniformly, wherein the component A is prepared by putting
alkyd resin and
alcohol solvents into a reaction kettle under the protection of
nitrogen, stirring the materials uniformly and heating the materials to 50-75 DEG C, adding first diluents, fillers, driers,
wax powder,
formaldehyde removal agents and an anti-
settling agent in sequence, continuing stirring, maintaining the temperature at 40-70 DEG C and reacting for 15-60 minutes, and discharging the material after returning to the
room temperature; the component B is prepared by putting second diluents into the reaction kettle under the protection of
nitrogen, stirring and insulating the materials, putting curing agents, a
levelling agent and a defoaming agent into the reaction kettle, insulating and stirring the materials, and discharging the material after returning to the
room temperature. The wood
lacquer has high
formaldehyde removal efficiency and good durability, dispenses with
recoating films, and is convenient to use.
