Effect of Modify by Silicon-Organic Substances of the Mineral Fillers on Some Properties of Composites Based on Epoxy Resin

摘要

Ultimate strength, softening temperature, and water absorption of the polymer composites based on epoxy resin (type ED-20) with unmodified and/or modified by tetraethoxysilane (TEOS) mineral diatomite are described. Comparison of experimental results obtained for investigated composites shows that ones containing modified filler have the better technical parameters mentioned above than composites with unmodified filler at corresponding loading. Experimentally is shown that the composites containing binary fillers diatomite and andesite at definite ratio of them possess the optimal characteristics - so called synergistic effect. Experimental results are explained in terms of structural peculiarities of polymer composites.
