Composites of unsaturated polyester resins applied in vacuum casting technology

Abstract

The paper deals with hydrophobization of bentonites (layered aluminosilicates) with quaternary ammonium salts (QAS) and potential application of the products obtained as fillers for preaccelerated unsaturated polyester resins (UPs) to be applied in vacuum casting. Natural purified bentonites of "Special" and "SN" type, enriched with montmorillonite and modified with QAS according to the earlier patented method were used. An addition of modified bentonites (1.5 or 3.0phr) to commercial preaccelerated UPs, caused a considerable improvement in mechanical properties (tensile strength, Brinell hardness and Charpy impact strength). Also, a clear effect of nanofiller concentration in resin on the quality of cast products was observed.
