摘要
以六甲基二硅氧烷、γ-巯丙基三乙氧基硅烷(KH-580)和正硅酸乙酯为原料,在酸性条件下通过水解共聚反应合成了含巯基MTQ树脂(SH-MTQ)。通过傅里叶红外光谱、核磁共振氢谱(1HNMR)、凝胶渗透色谱和热重,对所合成的树脂进行了表征和分析。以1-羟基环己基苯基甲酮(184)为光引发剂,考察了含巯基MTQ树脂对三丙二醇二丙烯酸酯(TPGDA)光固化过程和材料性能的影响,发现含巯基MTQ树脂的加入使得TPGDA的光固化速率和双键转化率有所提高,并且固化膜硬度、热稳定性、透过率和接触角等材料性能也有所提高。
The mercapto-based MTQ resin(SH-MTQ)was synthesized by hydrolysis copolymerization of hexamethyldisiloxane,γ-(methacryloyloxy)propyltrimethoxysilane and tetraethyl orthosilicate under acidic conditions.The obtained resin was analyzed by Fourier transform infrared spectroscopy,nuclear magnetic resonance spectroscopy(1HNMR),gel permeation chromatography and thermogravimetry.The effect of mercapto-based MTQ resin on the photocuring of TPGDA was investigated by using 1-hydroxycyclohexyl phenyl ketone(184)as a photoinitiator.It was found that the addition of mercapto-based MTQ resin increased the photocuring rate and double bond conversion rate of TPGDA,and the properties of cured film hardness,thermal stability,transmittance and contact angle also increased.
