| 摘 要： | 研究了对氨基酚(p-aminophenol)对低物质量比脲醛树脂的胶合强度和甲醛释放量的影响.结果表明,添加1%对氨基酚就可以显著提高胶合板的胶合强度,达到255%,符合Ⅱ类胶合板国标要求,甲醛释放量达E2级.进一步添加对氨基酚到2%,甲醛释放量可达E1级.对氨基酚改性脲醛树脂的性价比基本与常用的三聚氰胺改性相当.

| Abstract: | Effect of bonding strength and formaldehyde emission of plywood with low molar ratio urea-formaldehyde (UF) adhesive resin modified with p-aminophenol is investigated.The results show that the bonding strength is effectively increased to 255% with addition of 1% p-aminophenol which accords with the requirement of national standard,and E2 grade of formaldehyde emission.Formaldehyde emission can reach E1 grade with the content of p-aminophenol to 2%.The modifier of p-aminophenol in UF resin can equal with mel... |
