摘要

针对目前溶剂型涂料挥发量大、挥发性有机物质排放多、对环境污染严重的问题,采用本体聚合的方法以羟基丙烯酸酯单体、丙烯酸酯单体为原料合成了羟基丙烯酸酯树脂,并基于丙烯酸酯单体和甲基丙烯酸缩水甘油酯单体进一步合成了环氧丙烯酸酯树脂,优选异氰酸酯型固化剂制备了含双组分丙烯酸酯树脂的新型无溶剂反应型环保涂料。通过电化学工作站和中性盐雾试验考察了涂膜的耐腐蚀性能,利用热重分析仪考察了涂膜的耐热性能,利用傅里叶变换红外光谱仪对涂膜的化学结构进行了表征,比较了不同类型固化剂对涂膜性能的影响,通过扫描电子显微镜观察了涂膜的微观形貌。结果表明:制备的涂膜耐腐蚀性能良好,中性盐雾试验时间可以达到400h;耐热性能较好,300℃失重9%左右;硬度达到6H、沸水煮10h后未发现漆膜发生开裂等缺陷;涂膜表面光滑平整且具有良好的附着力、柔韧性、耐冲击等性能。

Abstract

In view of the present solvent coating volatilize quantity is large,volatile organic substances emissions,the environmental pollution problems is serious,the method of bulk polymerization was adopt with hydroxyl acrylate monomer and acrylic acid ester monomer as raw materials,synthesized hydroxy acrylic resin.and based on methyl acrylate monomers and glycidyl ester of acrylic monomer,synthesized epoxy acrylic resin.Further optimizing isocyanate curing agent,a new type of solvent-free reaction type environmental protection coating with two-component hydroxy acrylic resin was prepared.By electrochemical workstation and neutral salt spray test examined the corrosion resistance of the coating.The heat-resisting performance was investigated using thermogravimetric analyzer.Using fourier transform infrared spectrometer to characterize the chemical structure of the coating,compared the effects of the different types of curing agent on the properties of coating.By scanning electron microscope,observed the microstructure of the coating.The results shown that the corrosion resistance of the prepared film was good and the test time of neutral salt spray can reach 400h.Good heat resistance,300℃ weight loss of about 9%.No cracking or other defects were found after the hardness of the film reached 6H and being boiled by boiling water for 10 hours.The film surface was smooth,and had good adhesion,flexibility,impact resistance and other properties.
