喷涂阻燃柔性聚脲组合物及其应用
摘要：
本发明提供一种100％固含量的阻燃柔性聚脲组合物，该组合物由A、R两组分组成，所述的A组分由官能度在2到2.7之间的多异氰酸酯与分子量低于1000的阻燃多元醇合成的半预聚物，其中阻燃多元醇占30～50份，多异氰酸酯占70～50份，该半预聚物中的游离异氰酸酯基含量在13～18％之间；所述的R组分由5到30份官能度是2～3的扩链剂，40到60份端氨基聚醚，10到30份阻燃剂组成。该材料喷涂到底材上后，快速固化，形成强韧的阻燃柔性聚脲涂层。主要应用于舰艇舱室内部、工厂车间地坪、石化、无机化工等行业的钢制设备和钢结构支架的阻燃防腐等领域，也可用于地下储油罐、输油输气管线等金属重防腐领域。
摘要（英）：

This invention provides a flame-retardant flexible polyurea composition with 100% solid content. The composition is composed of component A and component R. Component A is quasi-prepolymer synthesized from polyisocyanate (functionality = 2-2.7) 50-70 parts and flame-retardant polyol (molecular weight lower than 1000) 30-50 parts. The quasi-prepolymer has a free isocyanate content of 13-18%. Component R is composed of amine chain extender (functionality = 2-3) 5-30 parts, amino-terminated polyether 40-60 parts, and flame retardant 10-30 parts. After being spray-coated onto base material, the composition can be rapidly cured to form coriaceous flame-retardant flexible polyurea coating layer. The composition can be used in flame-retardant and corrosion-resistant fields (such as steely equipment and steel frames), and can also be used in metal corrosion-resistant fields (such asunderground oil storage tank, and oil and gas pipelines).
