脲醛树脂
ure-aformaldehyde resins

   尿素与甲醛反应得到的聚合物。又称脲甲醛树脂。英文缩写UF。加工成型时发生交联,制品为不溶不熔的热固性树脂。固化后的脲醛树脂颜色比酚醛树脂浅,呈半透明状,耐弱酸、弱碱,绝缘性能好,耐磨性极佳,价格便宜,但遇强酸、强碱易分解,耐候性较差。商品名Beetle。尿素与37%甲醛水溶液在酸或碱的催化下可缩聚得到线性脲醛低聚物,工业上以碱作催化剂,95℃左右反应,甲醛/尿素之摩尔比为1.5~2.0,以保证树脂能固化。反应第一步生成一和二羟甲基脲,然后羟甲基与氨基进一步缩合,得到可溶性树脂,如果用酸催化,易导致凝胶。产物需在中性条件下才能贮存。线性脲醛树脂以氯化铵为固化剂时可在室温固化。模塑粉则在130~160℃加热固化,促进剂如硫酸锌、磷酸三甲酯、草酸二乙酯等可加速固化过程。脲醛树脂主要用于制造模压塑料,制造日用生活品和电器零件,还可作板材粘合剂、纸和织物的浆料、贴面板、建筑装饰板等。由于其色浅和易于着色,制品往往色彩丰富瑰丽。
