METHOD OF PRODUCING COMPOSITION FOR HARDLY COMBUSTIBLE PLASTICATE Russian patent published in 2017 - IPC C08L27/06 

FIELD: chemistry.

SUBSTANCE: mixing of polyvinyl chloride, dioctyl phthalate, calcium stearate, tribasic lead sulfate, epoxy resin, diphenylolpropane, adding trichloropropyl phosphate, and carbon black K-354 is carried out. Mixing of the mixture components is carried out under normal conditions, the composition is prepared by swelling the resulting mixture for 5 hours at 80°C and the addition of butadiene-nitrile rubber BNKS-33. The plasticate is produced by extruding and granulating the resulting composition.

EFFECT: increasing the fire resistance of the plasticate while maintaining its strength characteristics.
