摘要

提出前原位聚合聚酰亚胺齐聚物改性VE树脂的新方法.以与VE树脂发生反应且中、低温条件下惰性的单体为溶剂

就地合成了活性端基醚酰亚胺齐聚物

然后将VE树脂与含有活性端基醚酰亚胺的共聚单体共混、共聚

得到改性VE树脂(PE I/VE/RS)体系;研究了体系的反应性和固化物及复合材料的力学性能、阻燃性

并以扫描电镜为手段

对固化树脂的断口形貌进行了分析.结果表明:固化树脂宏观上呈透明状

微观上为均相结构

PE I作为增强相在接近分子水平上均匀分散在VE树脂中

正是由于这种相结构的存在

导致改性VE树脂(PE I/VE/RS)体系具有良好的力学性能和阻燃性

其弯曲强度为102.7M Pa

冲击强度为16.8 kJ/m2

玻璃化转变温度为134℃

极限氧指数为25.7.PE I/RS/VE树脂基复合材料的弯曲强度为311.6 M Pa

冲击强度为106.9 kJ/m2

极限氧指数为29.7.

Abstract

It was succeed in producing a tougher and more flame retardant vinyl ester cured resin via pre-in situ polymerization technology and its matrix glass farbic composites material.Tougher and more flame retardant vinyl ester resin was consists of three parts: vinyl ester resin(VE)

copolymerization monomer(RS) with VE

and polyimide oligmer(PEI).RS was used as solvent for PEI synthesizing and did not need to separate the PEI/RS mixture.Then VE was dissolved in PEI/RS mixture to obtain homogenous PEI/RS /VE system

which was pre-in situ polymerization technology.The final step was that PEI/RS/VE system was cured to obtain tougher and more flame retardant VE cured resin.PEI/RS/VE system was employed as matrix to manufacture glass fabric composites material.It was studied that the reaction of system

the mechanical properties PEI/RS/VE cured resin and PEI/RS/VE matrix glass fabric composites material.The morphological of fracture PEI/RS/VE cured resin was observed by SEM.The result showed that PEI/RS/VE cured resin presented transparent and had homogeneous structure in microstructure.This lead to PEI/RS/VE cured resin has excellent properties.(1) Flexural strength is 102.7 MPa

(2) impact strength is 16.8 kJ/m2

(3) LOI is 25.7

(4) glass transformation temperature is 134 ℃.(5)Flexural strength of PEI/RS/VE resin matrix glass fabric composite material is 311.6 MPa

(6) impact strength is 106.9 kJ/m2

(7) LOI is 29.7.
