-
摘要: 利用以植物蛋白为主要组分的生物质胶，生产在干燥状态下使用的家具及室内装修用刨花板。通过单因素试验对拌胶的方式和参数等进行研究，通过正交试验分析热压时间、热压温度、热压压力对刨花板物理力学性能的影响。结果表明：用卧式搅拌机在转速200 rmin－1下搅拌胶5～8 min，热压工艺参数为：时间6 min，温度180 ℃，压力2.550 MPa，制备的板材密度为0.74 gcm－3, 静曲强度为16.8 MPa，内结合强度为 0.49 MPa，表面结合强度为1.01 MPa，2 h吸水厚度膨胀率为1.8%，甲醛释放量为14.0 mgkg－1，外观质量、理化性能达到了GB/T 4897.1－2003和GB/T 4897.3－2003的要求，且甲醛释放量来自于木刨花。该种刨花板新产品的制备工艺是可行的。表5参8Abstract: To prepare a plant protein-based, biomass adhesive particleboard for interior fixtures （including furniture） to be used in dry conditions. Through the single factor test, the way and the parameters of the adhesive stired were studied, and the influence of the hot press time, press temperature and pressure on the physical and mechanical properties of the particleboard was studied by orthogonal test. Results indicated that the horizontal mixer design was used to stir the adhesive at 200 rmin－1 for 5－8 min, hot process parameters: 6 min press time, 180 ℃ temperature, and 2.550 MPa pressure. Appearance quality and properties of particleboard met the requirements for GB/T 4897.1－2003 and GB/T 4897.3－2003 standards. Properties of the particleboard: density 0.74 gcm－3, static bending intensity 16.8 MPa, internal bond strength 0.49 MPa, surface bonding strength 1.01 MPa, 2 h absorbing water thickness expansion rate 1.8%, free formaldehyde emission 14.0 mgkg－1. Additionally, the free formaldehyde emission of the particleboard contained in wood shavings. Thus, it would be feasible to prepare this new particleboard using this technology. ［Ch, 5 tab. 8 ref.］
