脲醛胶防老剂让脲醛胶终点粘度做大不凝胶保存期五个月
脲醛胶Hh高分子防老剂；Foreign Name: Urea-Formaldehyde Glue Hh Polymeric Anti-aging Agent 不改变各胶种摩尔比配方，具有抑制脲醛胶反应至终点放大分子量，延缓至测热胶30秒不骤胶、降低游离醛气味、缩短固化时间、提高热压成型车速，提高纤维含水率不爆板，提高内结合强度、表结强度、改善吸厚性等优异性能。It has the excellent properties such as inhibition of urea-formaldehyde glue reaction until end point, amplification of molecular weight, hot measurement glue without adhesion for 30s, reduction of free formaldehyde smell, shortening of curing time, increase of hot-pressing forming speed, improvement of fiber moisture without separation, and enhancement of internal bond strength, surface bond strength and thickness absorption, without changing the mole ration formula of various glues. 本产品是国际上能有效抑制和防止脲醛胶缩聚反应过程中和储存过程中树脂老化现象的发生（延长胶的储存期在3-5个月内不会丧失使用性能），其主要作用是抗热氧老化、抗臭氧老化，并且对金属离子、光和热的防老化防护效果极为显著。This product is the world’s unique new material that can inhibit and prevent the aging effect of urea-formaldehyde glues. It can effectively inhibit and prevent resin aging in the polycondensation reaction or storage process of urea-formaldehyde glue( to extend the storage life of the glue so that it will not loss its use performance within 3-5 months). Its primary functions are anti-heat and oxygen aging and antiozone aging. Moreover, it has very obvious anti-aging protective effects of metal ion, light and heat. 二、本产品外观颜色浅黄色树脂类状粉末状，沸点88—95度。II. The product is light yellow resin power in appearance, with a boiling point of 88—95°。 三、应用范围;广泛适用于E1级、E0级、P2级中（高）密度板、刨花板、胶合板、细木工板环保胶的生产 生产脲醛胶使用本产品时,请胶厂技术人员在我方技术人员的指导下添加。 四川省明仿化工研究所研制: 18982082185
