桉木阻燃胶合板胶合强度及润湿性研究
|
摘要
以磷酸氢二铵(DAP)和氢氧化铝(ATH)为阻燃剂,采用不同的配比和不同的浸渍处理工艺制备系列桉木阻燃胶合板,探讨了DAP协同ATH阻燃剂对桉木阻燃胶合板胶合强度和润湿性的影响。结果表明,阻燃处理方式不同,(DAP)与(ATH)的协同效果也不同。采用单板浸渍的处理方式,DAP与ATH协同作用对胶合板胶合强度起到减弱的效果;而采用成板浸渍处理,二者的协同作用明显提高了胶合板的胶合强度。ATH与DAP协同作用提高了桉木单板表面的润湿性,但其效果不如单独使用DAP时明显。
Diammonium phosphate(DAP)and aluminum hydroxide(ATH)were used as flame retardants.Different proportions of DAP and ATH and impregnating durations were tested while making eucalyptus plywood.Effects of DAP and ATH on bonding strength and wettability of the plywood were examined.The results showed that synergistic effect of DAP and ATH was different when flame retarding treatment was finished in different ways.In the case of board impregnation,synergistic effect of DAP and ATH improved the bonding strength of plywood,while for veneer impregnation,it had a negative effect on the bonding strength of the plywood.DAP and ATH treatment improved the wettability of veneers,but the effect was not obvious when treated with ATH alone.
