一种防腐阻燃聚天门冬氨酸聚脲防水涂料及其制备方法
摘要：
本发明公开了一种防腐阻燃聚天门冬氨酸聚脲防水涂料，由A、B两个组分组成，A组分为多异氰酸酯和防腐阻燃封端异氰酸酯的预聚体，所述的防腐阻燃封端异氰酸酯的预聚体以甲苯二异氰酸酯、聚醚多元醇为基本单体，磷氮协效阻燃剂为硬段扩链剂，稻壳二氧化硅为协效阻燃剂，制备而成；B组分为聚天门冬氨酸酯、聚合型改性聚天门冬氨酸酯、填料和少量助剂，该涂料凝胶时间长、拉伸强度大、断裂延伸率高，防水、阻燃、防腐性能优异且耐候性好，对环境友好，同时，该涂料可手工施工，不需要专门的大型喷涂设备，应用领域较广。
摘要（英）：

The invention discloses an anticorrosive flame-retardant polyaspartic acid polyurea waterproof paint and a preparation method thereof. The anticorrosive flame-retardant polyaspartic acid polyurea waterproof paint consists of a component A and a component B. The component A is a prepolymer of polyisocyanate and anticorrosive flame-retardant blocked isocyanate, the prepolymer of the anticorrosive flame-retardant blocked isocyanate takes toluene diisocyanate and polyether polyol as basic monomers, a phosphorus-nitrogen synergistic flame-retardant is used as a hard segment chain extender, and therice husk silica is used as a synergistic flame retardant, and the component B is polyaspartic acid ester, polymeric modified polyaspartic acid ester, a filler and a small amount of additives. The paint has long gelation time, high tensile strength, high elongation at break, excellent water resistance, flame retardancy, anti-corrosion performance, good weather resistance, and environmental friendliness, at the same time, the paint can be applied with manual construction, and does not require special large-scale spraying equipment, and the application field is wide.
