▎ 摘  要

NOVELTY - Manufacturing wood comprises: (i) removing dust, oil, paint, stains, contamination and foreign substances of wood, cleaning and sanding with sandpaper and sanding machine to enhance oil penetration on both side of wood; (ii) performing hot air heating of the sanded wood at 180-250 degrees C for 45-75 minutes in a hot air heating chamber, (iii) performing environmentally-friendly oil preparation process, secondary coating film formation process and environmentally-friendly oil wood penetration process, (iv) applying coating to the outer surface of the wood, (v) mixing urethane resin-based curing agent and curing agent for 3 minutes by stirring, then uniformly adhering to the wood using a small brush; (vi) applying a color top coat before the adhesive is completely cured; (vii) performing flame retardant waterproof layer on the upper surface of the wood on which the topcoat is formed, and (viii) performing ultraviolet irradiation process using ultraviolet irradiation device and curing. USE - The method is useful for manufacturing wood. ADVANTAGE - The method: utilizes environmentally-friendly oil for wood penetration; and improves the efficiency of painting and coating. DETAILED DESCRIPTION - Manufacturing wood comprises: (i) removing dust, oil, paint, stains, contamination and foreign substances of wood, cleaning and sanding with sandpaper and sanding machine to enhance oil penetration on both side of wood; (ii) performing hot air heating of the sanded wood at 180-250 degrees C for 45-75 minutes in a hot air heating chamber, (iii) performing environmentally-friendly oil preparation process, secondary coating film formation process and environmentally-friendly oil wood penetration process, (iv) preparing a primer coating composition by mixing a modified unsaturated polyester resin and a crosslinking monomer, then applying to the outer surface of the wood, where the coating composition is prepared by reacting e.g. polyol and polybasic acid, (v) mixing non-toxic environmentally-friendly urethane resin-based curing agent and curing agent for 3 minutes by stirring, then uniformly adhering to the wood using a small brush, where the adhesive composition includes e.g. polyurethane prepolymer, plant essence, diluent, thickener and graphene; (vi) applying a color top coat before the adhesive is completely cured; (vii) performing flame retardant waterproof layer on the upper surface of the wood on which the topcoat is formed, and (viii) performing ultraviolet irradiation process using ultraviolet irradiation device and curing. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method for manufacturing wood (Drawing includes non-English language text).
