Properties of carboxylated acrylonitrile/butadiene rubber containing "in situ" synthesized silica fillers

M. Zaborski J. Pietrasik

Abstract

From silica precursors we synthesized silica fillers in sol-gel reaction in the carboxylated acrylonitrile/butadiene rubber (XNBR). N-2-aminoethyl-3-aminopropyl-trimethoxysilane (DAMS) and tetraethoxysilane (TEOS) were used as fillers' precursors. It has been found that DAMS is a substance crosslinking XNBR. The network points are silsesquioxanes' domains containing amide as well as ionic bonds. Some part of points (similar to30%) decompose under ethylenediamine treatment. The bigger DAMS content the bigger crosslinking density of elastomer as ell as the stress at suitable elongation and tensile strength Tables 2 and 4). The dynamic properties measurements show that rganosilica compounds do not influence glass transitiontemperature of elastomer (Table 6) but in the range of 30-40degreesC the second maximum appears which is a transition connected to ionic aggregates activity. Addition of a mixture of DAMS + TEOS to the elastomer causes the increase of crosslinking of silsesquioxanes' domains and the filler shows tendency to creation of its own structure (Fig. 2). Si-29 NMR results show that mostly trifunctional structures Q(3) are obtained for equal ratio of silanes (1:1) but tetrafunctional structures Q(4) are also present (Table 1). The increasing of tetrafunctional structure Q(4) content, that is a synthesis of a filler with DAMS + TEOS mixture, leads to the increase of stress at suitable elongation, and tensile strength (Table 5).
