美国、日本、英国最新涂料专利速递

美国国家航空航天局推出了一种防覆冰涂料及其制备方法(美国专利公开号:US20170058168)。该防覆冰涂料含有至少1种具有柔性分子的单体结构。制备方法涉及的步骤包括:选取环氧树脂;选取氨基封端的固化剂,其中至少部分具有柔性分子的单体结构,且含有脂肪族链段或杂脂族链段作为侧链或主链;将上述环氧树脂与氨基固化剂混合。本专利还涉及了涂覆了金属层和抗结冰层的基材表面及其性能评价。

日本丰田中央研究所推出了一种多层热固性涂膜的湿碰湿涂装工艺及其涂饰件(日本专利公开号:JP2017023941)。该涂饰件由形成于底材上的底涂层和面涂层组成的多层涂膜构成,并采用湿碰湿工艺在底材上先后涂覆底涂层和面涂层,通过烘干处理待固化多层涂膜,使上下两道涂层同时固化。本专利的上涂层和下涂层材料经过优选,涂层的收缩率经过严格控制。例如,将水性涂料(丙烯酸-丙烯酸丁酯-甲基丙烯酸丁酯-Cymel325-2-丙烯酸异辛酯-4-丙烯酸羟丁酯-LatemulPD104-甲基丙烯酸甲酯-苯乙烯共聚物的二甲基乙醇胺盐)和溶剂型清漆(2-丙烯酸乙基己酯-2-甲基丙烯酸羟乙酯-甲基丙烯酸缩水甘油酯-苯乙烯共聚物)涂覆于钢板上,在130℃下烘30min,固化后制得多层涂膜。
