FIELD: chemistry.
SUBSTANCE: complex additive contains a polymeric sodium or polyalkylene oxide derivative of polymethylene naphthalene sulphonic acid, lignosulphonate and an electrolyte based on a mixture of rhodanide and sodium thiosulphate, wherein the additive further includes polyalcohols and sodium tripolyphosphate in the following ratio, (wt %): polymeric sodium or polyalkylene oxide derivative of polymethylene naphthalene sulphonic acid - 40-50; lignosulphonate - 10-20; polyalcohols - 8-10; sodium tripolyphosphate - 8-10; electrolyte based on a mixture of rhodanide and sodium thiosulphate - 12-15. The additive is added to a mixture based on clay and chamotte in amount of 0.3% of the weight of the mixture.
EFFECT: complex additive for refractory and ceramic articles provides a high index of plasticity of clay, which reduces pressing pressure and provides high bending and compression strength of the articles.
