高固体分酚醛环氧涂料的研究和设计

Study and Design on High-Solid Phenol Aldehyde-Epoxy Coatings

以液体酚醛环氧树脂为主基料树脂,脂肪酸改性环氧树脂为辅助基料树脂;以改性芳香胺、改性脂环胺、腰果壳油改性酚醛胺为固化剂制备了高固体分酚醛环氧涂料,该产品能够适用于更苛刻的腐蚀环境。还研究了不同固化剂及当量比对涂层物理化学性能的影响,并展望了该产品的应用前景。

Based on the binders of phenol aldehyde-epoxy resin and fatty acid modified epoxy resin, and on the hardener of modified aromatic amine, modified aliphatic cyclic amine and oil of cashew nut shell modified phenolic aldehyde amine, we prepared high-solid phenol aldehyde-epoxy coatings. This product can be applied in severe corrosion environment. This paper studies the relationships between ratio of curing agent in formulation and chemical and physical performances of phenol aldehyde-epoxy coatings. The potential application prospects also have been discussed.
