| 摘 要： | 研究了四马来酰亚胺对有机硅酚醛树脂的耐热性能、粘接性能和贮存性能等的影响。结果表明在四马来酰亚胺改性有机硅酚醛树脂固化过程中,四马来酰亚胺的双键与有机硅酚醛树脂的羟甲基发生加成反应,提高了有机硅酚醛树脂的耐热性能和粘接强度,并保持其韧性,但也造成常温贮存期有所下降。这是由于四马来酰亚胺在制备过程中缩合不完全,存在少量羧基和胺基,常温下与有机硅酚醛树脂羟甲基发生缩合造成的。

| Abstract: | The heat-resistant property, adhesive strength and storage life were studied for Tetramaleimide (TMI) modificated polyphenylmenthylsiloxane phenolic resin (PFSi) by IR, DSC and TG analysis methods. At the curing temperature of tetramaleimide modificated polyphenylmenthylsiloxane phenolic resin(TMI/PFSi), the C C group of TMI was condensed with —CH2OH of PFSi into crosslinking structure, since the heat-resistant property and adhesive strength of PFSi are increased, the toughness is kept, and the storage life is decreased. At room temperature, a small amount of the COOH, and NH2 groups of TMI (because of the steric effection, carboxyl and amino of TMI are not all condensed into imide) are condensed with —CH2OH of PFSi into a small amount of crosslinking structural oligomer, which makes the storage life of TMI/PFSi decrease. |
