酚醛泡沫塑料的增韧改性对阻燃性的影响

Effect of modification of phenol formaldehyde foam plastic on its fire retardant performance

介绍了酚醛泡沫塑料增韧改性的重要性及相关方法。通过对比试验,探讨了酚醛泡沫塑料在增韧改性后对其阻燃耐火性能的影响。实验结果表明:不同的增韧改性技术对酚醛泡沫塑料的阻燃性能影响不同。短切玻纤(无机物)增韧剂、复合改性增韧材料及改良酚醛树脂添加增韧剂等改变泡沫塑料的脆性,不改变泡沫塑料的阻燃性。

Importance and method of modifying phenol formaldehyde foam plastic was briefly introduced. Based on the comparison tests, the article discussed the effect of the modification of phenol roemaldehyde foam plastic on its fire retardant performance. The test results show that：different modification technologies had different effects on its fire retardant performance.
