玻纤布增强PPBES/PPENK树脂基层压板

Research on Glass-Fiber Cloth Reinforced PPBES/PPENK Laminate

将耐高温可溶解的杂萘联苯共聚芳醚砜(PPBES)与聚芳醚腈酮(PPENK)共混,采用溶液浸渍法制备了玻纤布增强PPBES/PPENK树脂基层压板。研究了树脂的相容性及树脂配比以及共混树脂含量对PPBES/PPENK层压板的室温及150℃弯曲强度、吸水率的影响,对层压板的介电性能、阻燃性能等进行了测试。结果表明:PPBES与PPENK完全相容。当PPBES/PPENK=4/6(质量比),树脂含量为35.4%时,层压板的综合性能最佳,且150℃的弯曲强度保持率为90.4%。在1MHz下,介电常数为3.5,tanδ为0.0037;在DC500V下,体积电阻率为5.9×1013Ω·m;阻燃性能达到V-0级。

The PPBES/PPENK laminate is prepared through the blend of poly（phthalazinone biphe- nylene ether sulfbne） （PPBES） and poly（phthalazinone ether nitrile ketone） （PPENK） which have thermostabil- ity and reasonable solubility by solution dipping process. The compatibility and ratio of resins are discussed. The effects of PPBES/PPENK resin content on the flexural strength at 25℃ and 150℃, respectively, and water abso- rption of the laminate are studied. The dielectric properties and flame retardancy of the laminate are tested. The SEM result approves that PPBES and PPENK are fully compatible. The results show that the laminate has optimum comprehensive pertbrmance when the blending resin with the ratio of PPBES/PPENK=4/6 content is 35.4%. Under condition of IMHz, the dielectric constant and dielectric loss are 3.5 and 0.0037, respectively. The volume resistiv- ity is 5.9x10^13Ω·m at DC500V. Its llame retardant property rate is UL94-V0.
