Water based coal tar emulsions |
摘要 |
Water-based coal tar emulsions are described which are prepared from a blend comprising coal tar, water, acrylonitrile-butadiene copolymer powders and clay. After the emulsion is prepared from the blend, a rubber latex may be added to the emulsion. Films obtained from the emulsions exhibit desirable elongation and tensile properties.
