摘要
以聚醚多元醇、多官能异氰酸酯等为主要原料反应合成NCO封端的异氰酸酯预聚物,并用含氟羟基树脂及羟基环氧树脂进行改性,制备出新型低表面能铝合金模板漆.对影响模板漆关键性能的因素进行研究,制备的涂层交联密度高,与铝合金附着粘接性强,耐磨性好,表面能低,疏水、耐沾污性能优异,能够为铝合金模板提供持久的耐环境因素及耐介质性等防腐蚀保护.
Abstract
In this study,polyether polyols and polyfunctional isocyanate were used as main raw materials to prepare NCO blocked isocyanate prepolymer.In addition,fluorinated hydroxyl resin and small molecule hydroxyl epoxy resin were used as modifier to synthesize a new-type of low surface energy aluminum alloy template paint.The factors affecting of template paint's key proterties were studied,the prepared coating has high cross-linking density,strong adhesion to aluminum alloy and high wear resistance,it also has low surface energy,excellent hydrophobic and stain resistance performance,which can provide durable corrosion protection against oil,chemical media and environmental factors for aluminum alloy template.
