摘要
采用相同的配方体系,分别以4种不同羟值、黏度的聚酯多元醇制备B2级PIR泡沫塑料。并对泡沫的性能进行了系统的检测分析对比。结果表明,降低聚酯多元醇羟值、增加异氰酸酯指数及增加阻燃元素如:磷、氮、卤素等对提高氧指数有利;卤素含量增加对提高氧指数有利,但会导致烟密度增高;提高异氰酸酯指数对于提高尺寸稳定性和整体强度有利;提高黏度能够改善垂直于生长方向上的压缩强度。
Using four kinds of polyester with different hydroxyl value and viscosity to prepare PIR foam of fireretardant B2.And the performance of foams were compared and analysed.The result was as following decreasing the hydroxyl value of polyester,increasing the index of isocyanate and introducing the fire-retardant elements to the structure of polyester,such as phosphorus,nitrogen and halogen,were helpful to improve the oxygen index;But the introduction of halogen will increase the smoke density;Besides,increasing the index of isocyanate was good to dimensional stability and compressive strength;In addition,increasing the viscosity of blend polyol will were improved the strength of horizontal direction and lower the anisotropy of strength.
