摘要
分别以PN、BPFN和BPAN为溴化环氧A80的固化剂,以DMP_30、HMTA和2_MZ为促进剂制备CEM_3覆铜板,研究了这三种线型酚醛树脂作为固化剂对CEM_3覆铜板力学性能、电性能、吸水性和耐热性等的影响。结果表明,以三种线型酚醛树脂为固化剂制备的CEM_3覆铜板的力学性能相近,而吸水性由高至低的顺序为PN>BPFN>BPAN,介电性能由高至低的顺序为BPFN≈BPAN>PN,Tg由高至低的顺序为PN>BPFN>BPAN。由BPAN和BPFN为固化剂制备的CEM_3覆铜板经150℃/2h后处理,耐变色性明显优于PN为固化剂制备的CEM_3覆铜板。
CEM-3 copper clad laminates （CCL） were made from epoxy bromide A80, curing agents of phenolic novolac（PN）, bisphenol F novolac （BPFN） and bisphenol A novolac （BPAN） with accelerants of DMP-30, HMTA and 2-MZ. The effects of these three novolacs on the properties of CEM-3 CCL, such as mechanical properties, electrical properties, water absorbance and heat resistance, were discussed. The results show that the mechanical properties of CEM-3 CCL fabricated by the three novolacs don＇t have distinguished difference. The water absorbance, dielectric properties and Tg of CEM-3 CCL from high to low are PN 〉 BPFN 〉 BPAN, BPFN ≈ BPAN 〉 PN and PN 〉 BPFN 〉 BPAN, respectively. The color changing resistance of CEM-3 CCL fabricated by BPFN and BPAN employed as curing agents is superior to that of CEM-3 CCL fabricated by PN under the condition of 150℃/2h post-treatment.
