Effects of Impregnated Paper and Reconstituted Decorative Veneer on Crack Resistance of Film Overlaid Blockboard
摘要
Abstract
Surface decorated blockboard with impregnated paper has become a dominant material for custom furniture because of its attractive appearance,environmental friendliness,and durability.Nevertheless,during the process of production and in the middle of service,the board frequently develops cracks on the surface that impair both its aesthetics and performance.To address this issue,the effects of reconstituted decorative veneer and melamine-impregnated film paper were investigated on the crack resistance performance of film overlaid blockboard.The study revealed that impregnated film paper with a basis weight below 80 g/m2 exhibited significantly better tensile properties than paper heavier than 80 g/m2.Wood-grain paper outperforms solid-color paper in tensile behavior;compared with solid-color paper of the same basis weight,wood-grain paper showed increased elongation at break and higher tensile strength.Because the tensile properties of impregnated film paper directly determine the crack resistance of the decorated blockboard,these differences were critical.In addition,increasing the moisture content of the reconstituted decorative veneer to 21％prevented cracking in the decorated blockboard within the 24 hours specified in the crack resistance test under the temperature-humidity conditions defined by GB/T 17657-2022"Test methods of evaluating the properties of wood-based panels and surface decorated wood-based panels";however,this protection was not consistent beyond 24 hours.Aqueous silicone resin modification established a dual protective mechanism:it significantly reduced the shrinkage of the reconstituted decorative veneer and simultaneously improved its transverse tensile properties,thereby enhanced the crack resistance of impregnated film paper-decorated blockboard.The modified system stayed stable up to 72 hours.关键词
