Effects of Epoxysiloxane on the Property of Acrylate Soap-free Coating
Abstract:
The acrylic ester emulsifier-free emulsion was synthesized from methyl methacrylate、n-butyl acrylate and methacrylic acid and the effects of epoxysiloxane on the glossiness,water absorption and pencil hardness of the polymer and on the Ca2+ stability of the emulsion were studied.It was found that the glossiness of the polymer was reduced from 89.8% to 70.9%,Ca2+ stability from 9.7 mL to 2.7 mL,pencil hardness from 2B to 3H and the water absorption from 24.9% to 0.2% with the increase of epoxy siloxane,respectively.The optimum molar ratio of epoxysiloxane to MAA was found to be 1.The granding analysis demonstrated the cross-linking reaction between epoxy siloxane and methyl acrylic acid.A crosslinking mechanism is proposed.
