热塑性塑料对环氧树脂冲击性能及热性能的影响
Effect of Thermal Plastic on Impact Strength and Thermal Properties of Epoxy Resin
摘要
Abstract
Three different types of thermoplastics such as polycarbonate ( PC ) , polyetherimide ( PEI) and Polybutylene terephthalate (PBT) ,were applied to modify epoxy in this paper. The properties, such as impact strength at cryogenic temperature (77 K) and room temperature (RT) and thermal properties,of the modified epoxy were characterized. Comparing to pure epoxy, the impact strength of epoxy modified by PEI, PC and PBT increased 50. 7% , 36. 4% and 30. 7% at 77 K, and increased 58. 5% , 39. 2% and 28. 9% at room temperature,respectively. The storage modulus of epoxy modified by PEI, PC and PBT and pure epoxy were 5 025 MPa,4 733 MPa,4 539 MPa and 3 853 MPa at - 150 ℃ .respectively. The temperature of onset decomposition of PEI,PC and PBT modified epoxy were 14 ℃,10 ℃ and 7 ℃ higher than that of neat epoxy. All that indicated that thermoplastic can increase the impact strength at 77 K and RT and thermal properties.关键词
