摘要 环氧树脂玻璃钢(EP-FRP)最常用的增塑增韧剂是DOP和DBP,具有来源广、价格低的优势,但同时又具有易挥发、耐久性差的缺点,因此采用SBS增韧EP-FRP,并与DBP增韧EP-FRP体系进行力学性能的对比分析。结果表明:DBP和SBS用量为7%时,EP-FRP/SBS体系的综合力学性能略好于EP-FRP/DBP体系;用量从7%增加到30%时,EP-FRP/DBP体系的综合性能随DBP用量增大进一步增强,但增加幅度趋于平缓。综合挥发性、价格等因素,SBS用量为7%左右时,具有取代DBP增韧EP-FRP的优势。 The most commonly toughening agents of EP-FRP were DBP and DOP, which had the advantages of source widly and low price, but also had the shortcomings of volatile, poor durability. So, SBS was used to toughening EP-FRP, and compared with the composite of DBP toughening EP-FRP. The result showed that when the content of DBP and SBS were about 7wt% ,the mechanical properties of EP-FRP/SBS composite was slightly better than EP-FRP/DBP composite. And when the content of DBP increasing from 7wt% to 30wt% , the comprehensive properties increasing with the content of DBP, but the increase rate tended to be gentle. Considering volatile,prices, and other factors, when the content of SBS was about 7wt% , had the advantage of replace DBP to toughening EP-FRP.
