高效膨胀性阻燃剂阻燃玻纤增强尼龙6的研究

以合成高聚合度的聚磷酸蜜胺为主阻燃剂,以自制的阻燃剂F为协同阻燃剂,复配成新型无卤膨胀性阻燃剂ANTI-9。研究了不同摩尔比的蜜胺/磷酸合成的聚磷酸蜜胺对玻纤增强尼龙(PA)6阻燃性能的影响,考察了ANTI-9对玻纤增强PA6的阻燃性能、力学性能的影响。结果表明,当蜜胺/磷酸的摩尔比为1.2时合成的聚磷酸蜜胺的阻燃性能最好,且产率和耐水性也比较好。在玻纤增强PA6中添加25%~30%的ANTI-9时,其阻燃性能可以达到UL94V-0级,且阻燃玻纤增强PA6的综合性能达到国外同类产品的指标。

STUDIES ON GLASS FIBER-REINFORCED NYLON 6 FLAME RETARDING WITH HIGH EFFECTIVE INTUMESCENT FLAME RETARDANT

The high effective intumescent flame retardant ANTI-9 was prepared with melamine phosphate which was synthesized by melamine and phosphoric acid as the major flame retardant, the flame retardant F as the flame retardant synergist. The effets of melamine phosphate which was synthesied with different mol ratio of melamine/phosphoric acid and the flame retardant ANTI-9 on flame retardant property, mechanical property of glass fiber reinforced nylon 6 were studied. The results showed that when the mol ratio of melamine/phosphoric acid was 1.2, the flame retardant property and water resistance property of melamine phosphate were perfect. The glass fiber reinforced nylon 6 containing 25%-30% content of flame retardant ANTI-9 had V-0 vertical firing grade while the combined property of glass fiber-reinforced nylon 6 was superior to that of foreign product.
