Study on Modification of Phenolic Foam by Blending
-
摘要: 通过添加改性剂对酚醛泡沫塑料进行共混改性,降低了酚醛泡沫塑料的脆性,提高了酚醛泡沫塑料的强度。改性酚醛泡沫塑料的综合性能良好,脆性质量损失低于2 0%,氧指数达45%~48%,最大烟密度小于10,尺寸稳定性好,线性尺寸变化在0.12%以下。Abstract: Phenolic foam's intensity is improved and its fragility is reduced by modifying agent. The fragility of the modified phenolic foam is below 20%, oxygen index within 45%~48%, max smoke density less than 10, dimension stability within 0.12%.
