中文摘要:
      用自行研制的EPR改性PP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EPR改性PP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0.98以上；在125～2 000 Hz范围内平均吸声因数可达0.52以上。
英文摘要:
      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.
