||||||||||||||||||||||||||||||||||
菲凡士环氧防静电地坪涂料的研制和应用 环氧抗静电地坪涂料的研制 ◎导电介质的选用: 目前,环氧地坪涂料已经得到了广泛应用,技术上比较成熟,如何在此基础上使之具有抗静电性能,是研制工作中的关键,而选择一种适用的导电物质则是关键中的关键。碳系导电物质主要是石墨和碳黑,是防静电涂料中比较常用的导电物质,其导电性较好,价格便宜,但由于其比表面积大,吸油量高,在制作无溶剂抗静电涂料时添加量稍大时涂料的粘度上升,自流平性变差,因此只能作为辅助添加导电物质,但可用于制作溶剂型抗静电涂料及导电腻子,颜色只能是黑色或深色。 金属导电介质:导电性能好,但涂料颜色受金属粉体色限制,该类粉末比重大,易沉降,在漆膜中易下沉,与空气接触易氧化(而惰性金属价贵),这都易导致涂膜导电性能不稳定。 金属氧化物复合导电粉:颜色浅,可制作各色抗静电涂料,导电性能基本能够满足要求,吸油量适中,价格较高。 根据上述导电介质的特性,制用无溶剂环氧自流平抗静电地坪涂料宜选用金属氧化物复合导电粉,包括导电云母粉、导电石英粉、导电氧化锌、导电钛白粉等,性能如下表(各个厂家生产的产品有一定差异):具体到某种颜色的自流平抗静电地坪涂料,宜根据颜色深浅度及防静电电阻要求选用一种导电介质或几种导电介质配合使用。 ◎成膜基料的选用: 无溶剂环氧自流平抗静电地坪涂料应选用低分子量的环氧树脂配以活性稀释剂及非活性稀释剂与固化剂反应成膜。 溶剂型环氧抗静电地坪涂料可选用中等分子量的环氧树脂与胺类固化剂作为成膜物质。 ◎助剂的选用: 由于导电介质与基料及着色颜料的相容性不佳,所以须选用合适的润湿分散剂以解决浮色发花现象,同时,对颜料的选用和分散应加以重视。由于导电粉沉降易导致漆膜表面抗静电性能下降,特别是自流平产品,涂膜厚,表干时间长,沉降更易发生。因而采用一些助剂避免此种现象的发生是必要的,同时需防止涂料流平性受助剂影响而下降。 另外,还需选用流平剂、消泡剂等助剂。 ◎固化剂的选用: 对于自流平抗静电地坪涂料,一般选用改性脂肪胺类固化剂,并根据施工环境的温度选用不同凝胶时间的产品,既要考虑涂料要有适当的使用期以便于施工操作,又要考虑干燥时间不能太长,避免导电粉沉降现象加重。 对于溶剂型防静电地坪涂料,可选用聚酰胺或其它胺类固化剂. |
