METHOD OF MAKING MIXED SOLID FUEL CHARGE Russian patent published in 2010 - IPC C06B21/00 C06D5/06 

FIELD: chemistry.

SUBSTANCE: invention relates to technology of making charges from mixed solid fuel. The method of making a mixed solid fuel charge involves grinding, fractionation and mixing different fractions of an oxidising agent, preparation of a mixture of binder with metallic fuel and additives, preparation of a mixture of hardener components and preparation of a fuel mixture, moulding, polymerisation, pressing and flaw detection of the charge. At the step for preparing a mixture of binder with metallic fuel and additives, rubber - oligomer polyvinyl isoprene urethane with terminal epoxy groups is divided into two portions. One portion of the rubber and a polymer chain extension - aniline is used to prepare a semi-finished product and is mixed with the second portion of the rubber and components of the mixture of binder with additives.

EFFECT: invention lowers viscosity and increases spreading coefficient of the fuel mixture in order to provide quality filling of charges, and also improves strength properties of the fuel.
