The Effect of Diluent on the Release of Benzene Series from Nitrocellulose-Lacquered MDF

Because the surface of MDF is not aesthetically pleasing, it usually needs to be veneered and then painted, but such a board releases harmful VOCs, among which Benzene Series most harmful. its series are group carcinogenic compounds. With diluents nitrocellulose (NC)-lacquered as research objects, release was studied provide scientific basis for pollution control reference eco-friendly paint production. The attenuant NC paint, anhydrous ethanol, ethyl acetate solvents mixed with different alcohol ester ratios were used in lacquer. Two kinds wood-veneered thickness (18 mm 8 mm) coated lacquer analyzed experiment. gas collected using small environmental chamber GC-MS. concentration released by 316.24 μg·m−3, that NC-lacquered thicknesses 18 284.44 μg·m−3 281.06 respectively. 14 Series, two it. order thick panel NC-M, NC-A, NC-E from high low. lowest occurred when ratio ethanol 1:3, amount components at 1:2. higher than MDF.
