摘    要
大气环境中外浮顶原油储罐顶因易积水而极易发生腐蚀，传统防护涂层存在环保性不高、耐候性差等问题，容易在大气环境中老化失效，达不到预期防护效果。近年来，高固体分涂料迅速发展，具有环保性强、耐候性强、施工便捷的特点，受到广泛关注。为此，研究了一种高固体组分的聚天门冬氨酸酯聚脲复合涂层体系，将其和传统聚硅氧烷复合涂层体系进行循环老化实验，并通过宏观和微观形貌观察以及光泽度、色差、附着力测试来对比研究涂层体系在室内加速实验中的耐老化腐蚀性能。结果表明：聚脲涂层体系表现出优异的抗老化性能，相比聚硅氧烷涂层体系具有更好的防腐蚀能力。该涂层体系可以尝试用于现场环境中储罐的保护，但在使用过程中需注意保护涂层，避免发生机械破损，以免破损处产生严重的涂层剥离和金属腐蚀现象。

Abstract
In atmospheric environments, external floating roof crude oil tanks were highly prone to corrosion due to water accumulation on the roof. Traditional protective coatings had issues such as low environmental friendliness and poor weather resistance, making them prone to aging and failure in atmospheric conditions, and they couldn't achieve the expected protective effect. In recent years, high-solids coatings had rapidly developed, characterized by strong environmental performance, excellent weather resistance, and convenient application, attracting widespread attention. This study investigated a high-solids component, polyaspartic ester-polyurea composite coating system, and compared it with a traditional polysiloxane composite coating system through cyclic aging experiments. The anti-aging and anti-corrosion performance of the coating systems in accelerated indoor tests was evaluated by analyzing macroscopic and microscopic morphology, gloss, color difference, and adhesion. The results showed that the polyurea coating system exhibited excellent anti-aging performance and had better corrosion protection compared to the polysiloxane coating system. This coating system could be considered for field applications to protect storage tanks; however, during use, it was necessary to ensure the coating is safeguarded against mechanical damage to prevent severe coating peeling and metal corrosion at damaged areas.
