| 摘 要： | 本研究采用美国ATLAS公司制造的HRR3热释放率系统,按照美国航空标准(FAA)要求, 测定了加入尿素、双氰胺、尿素-双氰胺三种发泡剂的膨胀型聚氨酯防火涂料涂覆的胶合板试件的燃烧热释放率(HRR),并比较了其阻燃性能.结果表明,同时加入尿素和双氰胺的复合膨胀型聚氨酯防火涂料的阻燃效果最好.

| Abstract: | An intumescent polyurethane flame-retardant coating, blended respectively with (carbamide,) dicyandiamide or a compound of carbamide and dicyandiamide as a foaming agent, was applied to plywood. Heat release rates for combustion of the coated plywood samples were tested according to FAA standards. Compared with plywood control specimens, the coated samples showed better flame retardancy. Among the three foaming agents, the compound of carbamide and dicyandiamide revealed the most effective results in retarding plywood combustion. |
