This study aims to tackle the drawback of non-abrasion-resistance of wood flooring with paint finish. A new method for preparing wood flooring with super-abrasion-resistant coatings by adding nano silicon carbide (SiC) particles to the paint was developed. As indicated by the results, the best mass fraction of nano SiC powder added in ultraviolet (UV) paint is 2.0%, the suspension liquid is stable when the mass concentration of sodium hexametaphosphate added is 2.5%, and it is better for the site humidity to remain below 75% when the nano SiC paint coating is applied. During the preparation of wood flooring with super-abrasion-resistant coating finish, the dosage of finish applied each time should not exceed 30 g/m2. During the sanding process, the sanding speed needs to be increased by about 2 m/s compared with that for the ordinary UV nano SiC primer in production. The test results of the performance of finished products indicate that the prepared wood flooring has better film abrasion resistance, adhesion of paint film, and film hardness. Meanwhile, because the paint film is durable and weather resistant, the service life of flooring is effectively extended, avoiding a significant waste of the product’s use value and broadening the product’s application range.
