Anti-fading coating for engineered wood

The invention discloses an anti-fading coating for engineered wood. The anti-fading coating comprises the following raw materials in parts by weight: 100-130 parts of aliphatic polyurethane resin; 2-6parts of an ultraviolet light absorber; 10-25 parts of a formaldehyde-free color fixing agent; 4-8 parts of hexamethylphosphoric triamide; 4-8 parts of potassium hydroxide; 20-30 parts of an acrylicemulsion; 2-6 parts of methyl salicylate; 2-6 parts of magnesium hydroxide; 10-25 parts of an adhesive; 10-30 parts of talcum powder; 15-30 parts of an anti-aging agent; 20-30 parts of a defoaming agent; and the balance of water. The weather resistance of the technical veneer is enhanced, the solarization resistance of dyed wood is remarkably improved, the technical veneer is protected against yellowing and discoloration, meanwhile, nano talcum powder is used for filling coating molecular gaps, the strong oxygen blocking function is achieved, and the problems since a color development system of the dyed wood is damaged
