Abstract
874,259. Propellant powders. IMPERIAL CHEMICAL INDUSTRIES Ltd. June 5, 1959 [Dec. 31, 1958], No. 42269/58. Addition to 861,810. Class 9(2). The method of preparing surface moderated double-base propellant powders claimed in the parent Specification is modified in that the granules which are treated contain about 3% of a non-volatile liquid non-explosive plasticizer for nitrocellulose miscible with nitroglycerine, e.g. dibutyl phthalate. The liquid explosive nitric ester is nitroglycerine, the resinous substance is a glyceryl ester of wood rosin, a pentaerythrityl ester of polymerized wood rosin, or lead naphthenate and is applied in an amount not exceeding 3% by weight of the granules together with a solid non-volatile non-explosive nitrocellulose gelatinizer soluble in nitroglycerine, e.g. sym.- diethyl diphenyl urea, and the tumbling is carried out with an excess of graphite at a temperature of 35‹-80‹C. The graphite completely covers the granules and is the chief surface moderating agent. The granules treated may also contain a small amount of the sym-diethyl diphenyl urea which acts as a stabilizer for the nitrocellulose as well as a gelatinizer. In examples granules containing nitrocellulose, nitroglycerine, dibutyl phthalate, sym-diethyl diphenyl urea, and potassium sulphate are treated with a glyceryl ester of wood rosin, sym.-diethyl diphenyl urea, and a wetting agent dispersed in water at a temperature rising from 25‹ to 40‹C., dried at 45‹C. and tumbled with excess powdered graphite at a temperature rising to 50‹C.
