【摘要】 介绍了在低毒脲醛树脂基础上合成的不同加成摩尔比的树脂的基本性能及预压性能,研究了单板含水率、固化剂种类及添加量和加成摩尔比四种不同因素对树脂预压性能的影响。结果表明单板含水率是影响树脂预压性能的主要因素,固化剂种类对板胚预压性能的影响不及固化剂用量影响显著,加成摩尔比为1.85的树脂预压性能较为优良。更多还原

【Abstract】 The paper introduced the basic properties and preloading performance of the different addition stage mole ratio of resin on the basis of the EO grade urea-formaldehyde resin;The paper studied the prepressing performance of resin under the influence of the four different factors,veneer moisture content,curing agents type and addition stage molar ratio.The results show that the veneer of moisture content is the main factor that influenced prepressing effect of resin preloading properties,the influence of curing agent type on the plate embryo preloading performance is less than curing agent content,and the mole ratio of 1.85 for bonus resin preloading performance is good.更多还原
