浸渍胶膜纸贴面工艺对饰面超薄纤维板平整度的影响
Effect of Thermosetting-Resin Impregnated Paper Lamination on the Flatness of Decorated Ultra-Thin Fiberboard
摘要
Abstract
Ultra-thin fiberboard is a recently developed high-density fiberboard with a thickness less than 1.5 mm.Owing to its thin thickness,good flexibility and high added value,it is widely used in the field of decorative wood-based panels and decorative materials.However,severe warping often occurs after ultra-thin fiberboards have been coated with melamine impregnated paper,which limits its practical application.Based on industrial production conditions,this study investigated the effects of ultra-thin fiberboard thickness(0.8～1.5 mm),resin content of melamine-resin impregnated paper(111.8%～167.4%),hot-pressing parameters(time,temperature,and pressure),and post-treatment(combined water spray and high-pressure treatment)on the flatness of decorated ultra-thin fiberboard with melamine-resin impregnated paper.Within the experimental scope,the flatness value decreased as fiberboard thickness increased,reaching the optimal value of 37.65 mm/m at a thickness of 1.5 mm.In contrast,the flatness increased with increasing resin content,with the optimal value of 185.88 mm/m obtained at a resin content of 111.8%.Among the hot-pressing parameters,temperature had the most significant effect on flatness.Under the conditions of 10 s duration,190℃temperature,and 2 MPa pressure,the optimum flatness value was 214.71 mm/m.Analysis by X-ray computed tomography and profile density measurement indicated that asymmetric density and stress differences between the upper and lower surfaces of the decorated ultra-thin fiberboard were the main causes of warping;the profile densities of the uncoated and coated surfaces were 860 and 1 250 kg/m³,respectively.After the combined water-spraying and high-pressure post-treatment was applied,these density and stress differences between the two surfaces were effectively reduced,and the flatness value decreased from 221.57 mm/m to 72.35 mm/m,indicating a marked alleviation of warping.This study provides practical process guidance for manufacturing decorated ultra-thin fiberboard with optimal flatness.关键词
