Evaluation of Attapulgite Clay Content from Piauí in Sorption Characterization of Water in the Polyester Matrix Composites

Abstract:

The physico-chemical characteristics of attapulgite clay confer appropriate properties to their different industrial uses, such as: Drilling fluid, bleaching of vegetable oils, mineral and animal grease and oil absorbents, pet waste absorbents (pet litter), purification of drinking water etc. The aim of this study was the chemical modification of attapulgite originally from state of Piauí, for applications in polyester-based composites. The unmodified and modified clay were characterized by X-ray diffraction (XRD). In order to evaluate the interaction of clays with organic solvents, the test of Foster swelling with gasoline, diesel and toluene was conducted. The polyester resin-based composite and clay unmodified and modified in different percentages were molded by hand lay up technique and they were characterized by water sorption.
