摘要
利用腰果酚缩水甘油醚与经酸酐酸化后的酚醛环氧丙烯酸酯反应,得到改性碱溶性酚醛环氧丙烯酸酯树脂,并将其应用到感光型阻焊油墨中。实验通过红外以及核磁氢谱证明了目标产物的成功合成。该改性树脂所制得的涂层具有优异的感光性、耐热性以及力学强度,同时柔韧性得到提升。将其应用到感光型阻焊油墨中,与用未改性碱溶性酚醛环氧丙烯酸酯树脂制得的油墨相比,在保持良好显影性和感光性的同时,解析度由140μm提高到了85μm,显影线条的最小侧蚀由37.1μm降低到10.4μm,展现了优异的抗蚀刻能力。
An o-cresol formaldehyde epoxy acrylates resin modified by cardanol glycidyl ether(EATC)was prepared and used in solder resist ink.The synthesis of EATC was studied and characterized in detail by IR spectroscopy and 1HNMR spectrum.The coating made of modified resin exhibited good photosensitive,thermal and mechanical properties.Besides,the flexibility of the film became better.Compared to unmodified o-cresol formaldehyde epoxy acrylates resin,the solder resist ink which consist of EATC has good performance in photosensitivity.The resolution increased from 140 to 85μm,and the minimal etching resistance decrease from 37.1 to 10.4μm.
