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 used toughening toughening agent for EP-FRP is DOP and DBP, which has the advantages of wide source and low price, but also has the disadvantages of easy volatilization and poor durability. Therefore, the toughening of EP- FRP, and DBP toughening EP-FRP system mechanical properties of comparative analysis. The results showed that the overall mechanical properties of EP-FRP / SBS system were slightly better than that of EP-FRP / DBP system when the dosage of DBP and SBS was 7%. When the dosage was increased from 7% to 30%, the combination of EP-FRP / DBP system Performance with DBP dosage increased further, but the increase rate tends to be gentle. Comprehensive volatility, price and other factors, SBS dosage of about 7%, has the advantage of replacing DBP toughened EP-FRP.
