Abstract

Polyurea is a synthetic material made by the reaction of isocyanate and polymer blend-containing amines. Due to its outstanding mechanical properties and fast curing, polyurea-based coatings have found dozens of applications, including waterproofing and anti-corrosion coatings. Further development of this material can create a flame-retardant product, a good alternative for common products available on the market, such as intumescent coatings. To improve the flame retardancy of polyurea, several flame retardants were investigated. The influence of aluminum hydroxide, resorcinol bis(diphenyl phosphate) (RDP), and tris chloropropyl phosphate (TCPP) on flame retardancy and morphology was studied. The following methods were used: infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis, limiting oxygen index, and tensile strength. The examinations mentioned above showed the improvement of flame-retardancy of polyurea for two products: chlorinated organophosphate and organophosphate. Nevertheless, using the chlorinated organophosphate additive caused a rapid deterioration of mechanical properties.

摘要

聚脲是一种由异氰酸酯与含聚合物共混物的胺反应制成的合成材料。由于其出色的机械性能和快速固化特性，聚脲基涂料已获得数十种应用，包括防水和防腐涂料。这种材料的进一步开发可以制造出一种阻燃产品，是市场上现有普通产品（如膨胀型涂料）的良好替代品。为提高聚脲的阻燃性，研究了几种阻燃剂。研究了氢氧化铝、间苯二酚双（二苯基磷酸酯）（RDP）和三氯丙基磷酸酯（TCPP）对阻燃性和形态的影响。采用了以下方法：红外光谱、扫描电子显微镜、热重分析、极限氧指数和拉伸强度。上述检测表明，两种产品（氯化有机磷酸盐和有机磷酸盐）提高了聚脲的阻燃性。然而，使用氯化有机磷酸盐添加剂会导致机械性能迅速恶化。
