| 摘要: |
| 采用熔融预聚法制备N,N'-4,4'-二苯甲烷双马来酰亚胺(BMI)/二烯丙基双酚A(DBA)/聚醚砜(PES)/聚醚酮(PEK)(简称B/D/P/P)改性树脂体系。研究了改性树脂的固化反应性、力学性能及热稳定性。并对不同配比PES/PEK增韧后树脂体系的性能进行比较。结果表明,PEK/PES的加入能明显提高树脂的韧性和强度。在合适的配比下,5wt%PEK/PES的加入就可使改性体系较纯的基体树脂体系冲击强度增加68.5%,弯曲强度增加50.8%。另外,改性树脂体系的热稳定性也较纯的体系以及单一热塑性塑料改性体系有所提高。PES/PEK同时加入效果比PES和PEK单个加入的改性效果明显。 |

| Abstract: |
| The introduction of the full papar reviews some relevant matters and then proposes the modification men-tioned in the title,which we believe improves bismaleimide resin and which is explained in section 1.Its core con-sists of: "The modified resin system of N, N'-4, 4'-diphenylmethanebismaleimide (BMI) /o, o'-diallylbisphenol(DBA) /Polyether sulphone(PES) /Polyether ketone (PEK) was prepared by melting prepolymerization.The curingreactive,mechanical properties and thermal stability were also investigated.The performances of the PES/PEKtoughening resin system under different proportions were contrasted."The results,presented in Figs.1 through 4and Tables 1 and 2,and their analysis show preliminarily that both the toughness and the strength of the resin couldobviously increase by adding PEK/PES.The 5% PEK/PES addition could make the modified resin system's impactstrength increase by 68.5% and its bending strength increased by 50.8%.In addition,the thermal stability of themodified resin system improves more than either that of the pure system or that of a single thermoplastically modifiedsystem.The effect of modification with PES/PEK was more effective than either with PES or PEK individually. |
