| 摘 要： | 用自行研制的 Ｅ Ｐ Ｒ 改性 Ｐ Ｐ基阻燃泡沫材料制成微穿孔板，研究其吸声特性及规律，并与 Ｅ Ｐ Ｒ 改性 Ｐ Ｐ基阻燃非泡沫材料微穿孔板进行对比。结果表明，泡沫材料微穿孔板吸声体在中、低频率区域的最大吸声因数可达０９８ 以上；在１２５ ～２ ０００ Ｈｚ 范围内平均吸声因数可达０５２ 以上。

| Abstract: | A flame retardant foam sheet was made with self developed EPR modified PP.The sound adsorption of EPR modified foam sheet was investigated by comparing to that of EPR modified non foam sheet.The results showed that the maximum sound adsorption factor of the foam sheet could reach above 0.98 at the medium and low frequencies;and the average sound adsorption factor could reach above 0.52 at the frequencies from 125 to 2 000 Hz. |
