密封胶 (Sealant)

密封胶，英文为 Sealant，是一种具有良好粘接性和密封性的材料，用于填充缝隙、裂缝和连接处，以防止液体、气体、热量、噪音等的渗透。

材料

密封胶的种类繁多，根据其化学成分可分为以下主要类型：

• 硅酮密封胶 (Silicone Sealant): 以硅酮聚合物为基础，具有优异的耐候性、耐高温性、耐化学腐蚀性以及良好的弹性。常用于建筑、汽车、电子等领域。
• 聚氨酯密封胶 (Polyurethane Sealant): 以聚氨酯树脂为基础，具有优异的耐磨性、耐油性、高强度和良好的附着力。常用于建筑、汽车、船舶等领域。
• 丙烯酸密封胶 (Acrylic Sealant): 以丙烯酸酯为基础，具有良好的耐候性、易于涂刷和良好的可涂性。常用于建筑、室内装饰等领域。
• 聚硫密封胶 (Polysulfide Sealant): 以聚硫聚合物为基础，具有优异的耐油性、耐化学腐蚀性以及良好的弹性。常用于航空、船舶等领域。
• MS 密封胶 (Modified Silicone Sealant): 是硅酮聚合物改性而成，兼具硅酮和聚氨酯的优点，具有良好的粘接性、耐候性以及环保性。常用于建筑、汽车等领域。
• 其他密封胶: 包括但不限于丁基密封胶、橡胶密封胶等。

目的

密封胶的主要目的是：

• 密封: 防止液体、气体、热量、噪音等的渗透。
• 粘接: 将不同材料连接在一起。
• 保护: 保护连接处免受腐蚀、磨损等。
• 绝缘: 提供电气绝缘。

功能

• 弹性: 能够适应材料的热胀冷缩。
• 耐候性: 能够抵抗紫外线、温度变化、湿度等环境因素的影响。
• 耐化学腐蚀性: 能够抵抗酸、碱、盐等化学物质的腐蚀。
• 粘接性: 能够将不同材料牢固地粘接在一起。
• 耐久性: 能够长期保持密封和粘接性能。

使用场景

• 建筑: 门窗密封、屋顶防水、卫生间防漏、幕墙密封等。
• 汽车: 车身密封、发动机密封、挡风玻璃安装等。
• 室内装饰: 厨房、卫生间防霉、墙面裂缝修补等。
• 工业: 管道密封、设备连接、电子元件封装等。
• 船舶: 船体密封、甲板连接等。

常见类型

• 中性硅酮密封胶: 具有良好的粘接性，适用于多种材料。
• 酸性硅酮密封胶: 固化速度快，适用于玻璃、陶瓷等材料。
• 聚氨酯密封胶: 适用于高强度、高弹性的场合。
• 丙烯酸密封胶: 适用于室内装饰，易于涂刷和修补。
• MS 密封胶: 环保、无味、粘接力强。
