Abstract
为探究制胶阶段和压板阶段的6个因素(生物油替代率、醛酚比、热压温度、热压时间、热压压力、涂胶量)对胶合板中甲醛和总挥发性有机物(TVOC)含量的影响,在单因素试验基础上,设计L25(56)正交试验对工艺参数进行优化.采用顶空固相微萃取法(HS-SPME)和气相色谱/质谱(GC/MS)联用技术对生物油酚醛树脂胶合板(BPFP)中游离甲醛和除甲醛外的TVOC、苯酚进行检测.结果表明:当生物油替代率为60％,醛酚比值(nF/nP)1.6,热压温度190℃,热压时间4 min,热压压力1.2 MPa,涂胶量为200 g/cm2时,胶合板中含甲醛最低.热压温度和压力对甲醛含量有显著的影响,生物油替代率和涂胶量对胶合板中游离甲醛含量的影响较小;在生物油替代率为60％,醛酚比值2.2,热压温度190℃,热压时间5.5 min,热压压力1.4 MPa,涂胶量为210 g/cm2时,胶合板中TVOC含量最低.
