摘要

To confer thermal resistance to anticorrosive sheeting conforming to invention RSR No63827, the following one stage mix is prepd. in an internal mixer: (all wt.%-s): 10-50 synthetic rubber; styrene-butadiene, polyisoprene, acrylonitrile, butyl or polychloroprene. 0-40 granular of high or low density polyethylene. 0-40 polyvinyl-chloride (emulsion or suspension type). 0.5 carbon black, 0.5 quartz-flour, borytes, colloidal kaolin, calcium-carbonate. 0-5 zinc or magnesium-oxide; 0-3 sulphur. 0-1.5 thiuram or di-phenyl-guanidine accelerator. 0-30 process oil. 0-30 tar. 1-5 stearne. 0-15 phenolic resin. 0-4 beta-naphthol. 0-5 2,2-methylene-bis, 4-methyl-, 6-tert-butyl-phenol. Sheets of 0.5-6mm thickness are calendered after mixing at 80-100 deg.C for 10-20 mins.
