摘    要:为提高胶合板胶合强度,降低其燃烧性能,以苯丙/二氧化硅(SiO2)作为改性剂,通过物理共混的方法制备了改性脲醛树脂(UF)胶。研究了苯丙/二氧化硅改性剂粒径、添加量对胶合板胶合强度和燃烧性能影响。改性剂粒径设置为60,800,10 000目等3个水平,选出最适粒径后,设置添加量(质量分数)为0,5%,10%,15%,20%,25%等6个水平。结果表明:改性剂粒径和添加量对胶合板胶合强度和燃烧性能影响显著,当粒径为60目,改性剂添加量为15%时,制备的胶合板性能最佳,胶合强度为1.33 MPa,热释放总量为16.3 MJm-2,释烟总量为149.80 m2m-2。图4表4参8

Abstract:To determine how different particle sizes and additions of styrene-acrylic-SiO2 influenced the bonding strength and combustion properties of plywood, a novel urea-formaldehyde (UF) resin adhesive was modified through physical blending with styrene-acrylic-SiO2, and flame retardant and bond strength test were carried out. Results showed that a particle size of 60 mesh and a 15% addition of styrene-acrylic-SiO2 had a strong effect on bonding strength and combustion properties of plywood. With these conditions, plywood had the best performance when bonding strength was 1.33 MPa, total heat release was 16.3 MJm-2, and total smoke release was 149.80 m2m-2. [Ch, 4 fig. 4 tab. 8 ref.]
