Carbon-containing fillers for polymers from organometallic compound pyrolysis products
A study of the physicochemical properties of carbon-containing fillers obtained by the pyrolysis of organometallic compounds of aluminum with organic acids, cellulose, and surfactants, and an evaluation of these pyrolysis products as rubber fillers, is presented. These studies used organometallic compounds (sludge-coagulate after treatment of water with aluminum sulfate) containing fatty, sulfonic, and humic acids in respective amounts of 4.0%, 4.5%, and 15.0%; a surfactant of the OP-10 type (polyoxyethylated nonylphenol) in accounts of 2.5%; cellulose in amount of 8.0%, kaolin with a dispersity of 2.5 ..mu..m and above in amount of 25%, and x-ray-amorphous aluminum hydroxide in amount 40%. The surface activity of the CCF was evaluated on the basis of ESR spectra. The nature and concentration of paramagnetic centers (PMC) in the sludges before and after heat treatment were determined in a type TSN-25A ESR spectrometer in the 3-cm range. An experimental batch of the CCF for use in rubber compounding was obtained by a pyrolytic process at 400-500/sup 0/C. The quality of the CCF as a filler was evaluated by an analysis of the properties of a rubber mix and by tests on rubber specimens prepared from SKA-30 ARKM-15 raw rubber. Results showed that the CCF has a favorable effects on the processing indices of the rubber mix, accelerating the vulcanization process. The CCF makes it possible to obtain finished rubbers with high elasticity, almost twice that of chalk-filled rubbers as determined by the elongation. Rubbers with the CCF are also better in quality than rubber based on the most active and expensive filler, DG-100 carbon black.
