摘　　要：将含二氮杂萘酮结构、耐高温可溶解的聚芳醚砜(PPBES)与聚芳醚腈酮(PPENK)共混,采用溶液浸渍法制备了玻璃布增强PPBES/PPENK树脂基层压板。讨论了树脂的相容性及树脂配比,研究了共混树脂含量对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),树脂质量分数为35.4%时,层压板的综合性能最佳,且150℃的弯曲强度保持率为95.7%。在1 MHz下,介电常数为3.5,tanδ为0.0037;在DC 500 V下,体积电阻率为5.9×1014Ω·cm;阻燃性能达到V-0级。The PPBES/PPENK laminate was prepared through the blend of Poly（ phthalazinone biphenylene e ther sulfone） （PPBES） containing phthalazinone and poly （ arylene ether nitrile） （PPENK） with heatresitant and soluble by solution dipping process. The compatibility and ratio of resins were discussed. The effects of PPBES/ PPENK resin content on the flexural strength （25℃, 150℃ ） and water absorption of the laminate were studied. The dielectric properties and flame retardaney of the laminate were tested. The SEM result approved that PPBES and PPENK are fully compatible. When PPBES/PPENK = 4/6 and the blending resin content is 35.4%, the laminate has optimum comprehensive performances. And the retention rate of flexural strength on 150℃ is 95.7%. Under con dition of 1MHz, the dielectric constant and dielectric loss is 3.5 and 0.0037, respectively. The volume resistivity is 5.9x10^14 at DC 500 V. Its flame retardant property rate is UL94V0.
