Claims13
Binding and plasticizing agent for preparing carbon-containing, refractory materials from a mixture of:
- (a) 0.1 to 90 parts by weight of a liquid, curable synthetic resin,
- (b) 0.1 to 70 parts by weight of a liquid inorganic phosphate material, and
- (c) 0.1 to 30 parts by weight of a composition selected from the group consisting of a liquid anionic surface-active agent, a liquid nonionic surface-active agent, an organic base, and combinations thereof, wherein the sum of the components through (c) shall always be 100.
Binding and plasticizing agent for preparing carbon-containing, refractory materials from a mixture of:
- 30 to 70 parts by weight of a liquid, curable synthetic resin,
- 10 to 50 parts by weight of a liquid inorganic phosphate material, and
- 5 to 30 parts by weight of a composition selected from the group consisting of a liquid anionic surface active agent, a liquid nonionic surface-active agent, an organic base, and a combination thereof,
- wherein the sum of the parts of the mixture is 100,
- in which the liquid synthetic resin consists of a phenolic resin, a novolak resin, or a combination thereof,
- in which the liquid phosphate material consists of monoaluminum phosphate,
- in which the liquid surface-active agent consists of ethylene oxide adducts or glycols, and
- in which the organic base consists of an aminoethanol.
