摘要
以丙烯酸树脂为主要成膜物质,以多异氰酸酯树脂为固化剂,通过添加不同比例的贝壳粉,制备了多种新型防腐涂层。通过附着力、光泽度、硬度、柔韧性、抗冲击性、耐化学性能的对比,对丙烯酸聚氨酯漆的力学性能与耐腐蚀能力进行了评估,确定了贝壳粉最佳添加量后,得到了一种具有良好防腐性能、成本低廉的新型生物基防腐涂层。结果表明:适当添加贝壳粉,可以提升丙烯酸聚氨酯漆部分物理性能,包括附着力、光泽度、硬度和抗冲击性能。
A variety of new anti-corrosive coatings were prepared with acrylic resin as the main film forming material and polyisocyanate resin as curing agent by adding different proportions of shell powder.The mechanical properties and corrosion resistance of acrylic resin paint were evaluated by comparing adhesion,gloss,hardness,flexibility,impact resistance,acid and alkali resistance.After determining the optimal amount of shell powder,a new bio-based anticorrosive coating with good anti-corrosive properties and low cost was obtained.The results showed that the appropriate addition of shell powder cuold improve some of the physical properties of acrylic polyurethane paint,including adhesion,gloss,hardness and impact resistance.
