Synthesis of Mercapto-based MTQ Resin and Its Effect on Photocuring Properties of Acrylate System

doi:10.7517/issn.1674-0475.190520

Abstract

Abstract: 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.

Key words: UV-curable, ruthenium-based MTQ resin, tripropylene glycol diacrylate, material properties
