摘要

为了改善热固性树脂装饰层压板（HPL）的阻燃性能,采用有机磷化合物作为阻燃剂,对HPL底层纸浸渍用酚醛树脂胶进行了改性处理,研究了阻燃剂类型和用量的影响。结果表明:有机磷化合物作为反应型阻燃剂的效果略好。作为添加型阻燃剂时,增加其用量能显著提高装饰板的阻燃性能;当用量大于7%时,装饰板的阻燃性能可达到极难燃级。

Abstract

To improve fire-resistance of high-pressure laminates （HPL） made from thermosetting resin impregnated papers, an organic compound of phosphorus was added to the phenol-formaldehyde resin. Depending on whether the phosphorus compound was added before or after the preparation of PF resin, it acted as a reacting flame retardant or an additive flame retardant respectively. Results found that superior fire resistance resulted when it acted as a reacting flame retardant. When used as an additive flame retardant, the fire-resistance of the HPL increased as the level of phosphorus compound increased. When the amount was beyond 7% （on the absolute dry weight of PF resin）, the HPL no longer supported combustion.
