玻璃纤维增强SAN的研制及其在电器上的应用

利用硅烷偶联剂改善玻璃纤维(GF)与(苯乙烯/丙烯腈)共聚物(SAN)之间的相容性,采用聚烯烃弹性体(POE)接枝马来酸酐(POE-g-MAH)对GF增强SAN体系进行增韧,制备了综合性能较好的GF增强SAN材料.结果表明,当GF、POE-g-MAH、偶联剂的质量分数分别为20%、6%和0.4%时,材料的综合力学性能最好:缺口冲击强度达到8.9 kJ/m2,拉伸强度、弯曲强度分别为104、130 Mpa;所研制的GF增强SAN材料已于空调轴流、贯流风扇等产品中批量应用.

PREPARATION OF GLASS FIBER REINFORCED SAN AND APPLIED IN WIRINGS

Silane coupling agent is adopted to improve the compatibility between glass fiber(GF) and SAN.Maleic anhydride grafted(ethylence/octene) copolymer(POE-g-MAH) is prepared to toughen SAN/GF system,and GF reinforced SAN with good comprehensive property is prepared.The experiments results show that when the contents of GF,POE-g-MAH and silane coupling agent are 20%,6% and 0.4% respectively,the mechanical properties of the composites are the best,with the notch impact strength reaching 8.9 kJ/m2,tensile strength...
