Suitable polymers or copolymers are obtained from unsaturated acids, their esters and anhydrides, unsaturated alcohols, their esters and ethers, unsaturated ketones and acetals, and condensation products of aldehydes and phenols and of diols and dicarboxylic acids. Several examples of such polymers are given. In examples the nitric esters and nitro-compounds are nitroglycerine, nitroglycol, nitroglycerine - nitroglycol mixture, diethyl glycol dinitrate, and a liquid mixture of isomeric dinitrotoluenes; the polymers and copolymers are polymethacrylic acid, polyvinyl acetate, a copolymer of ethyl acrylate and vinyl chloride, phenol-formaldehyde resin, and polyvinyl pyrrolidone or a copolymer thereof with vinyl acetate.

It is believed that the associative thickener provides a network of physical linkages throughout the emulsion which network can be reversibly broken down.

Method for obtaining large-dispersed spherical powder

FIELD: weapon. SUBSTANCE: invention relates to the production of spherical gunpowder for small arms and small caliber artillery. Large-dispersed spherical powder is obtained by preparing a powder varnish, by dispersing it into spherical particles, and then removing the solvent therefrom. Initially, during 60-90 minutes in a mixer, a powder varnish consisting of 70.0-84.0% by weight of 1 Pl pyroxylin is prepared, 15.0-28.8% by weight of the propellant, 1.0-1.2% by weight of the chemical stability stabilizer and solvent-ethyl acetate with the module of 1.5-2.5 (volume) to charge all components. Then the powder varnish is injected with excess pressure into the granulator, where it is cut into the strictly prescribed dimensions of the powder element. Further, the powder elements enter the reactor, where the particles are spherically shaped in the presence of 3-4 wt.% of water with the content of 0.6-1.3% by weight of a protective colloid (leather glue) and 0.6-1.3% by weight of sodium sulfate for 60-90 minutes, after which a volatile solvent is removed from the propellant particles. EFFECT: method ensures the production of spherical particles with the diameter of up to 4 mm with a high yield of the product. 1 cl, 1 tbl, 5 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 653 029 C1 (51) МПК C06B 25/18 (2006.01) C06B 21/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК C06B 25/18 (2006.01); C06B 21/0016 (2006.01) (21)(22) Заявка: 2017105330, 17.02.2017 (24) Дата начала отсчета срока действия патента: Дата регистрации: 04.05.2018 (45) Опубликовано: 04.05.2018 Бюл. № 13 2 6 5 3 0 2 9 R U (56) Список документов, цитированных в отчете о поиске: RU 2439042 C, 10.01.2012.

Method of producing gun powder with minimum web thickness for small arms cartridges and special-purpose ones

FIELD: weapons and ammunition. SUBSTANCE: invention relates to production of gun powders, which can be used for charging cartridges for small arms, as well as special-purpose cartridges, for example, construction and industrial cartridges. Method of producing a gun powder with the minimum web thickness comprises production of powder elements with the size of not more than 0.7 mm their preliminary drying to the humidity of not more than 15 %, coating the powder elements with a current-conducting material, rolling the powder elements into plates with the thickness of not more than 0.18 mm on hot rolls, the temperature of which is not more than 100 °C, final drying and averaging of physical and chemical characteristics by blending. At the stage of coating the powder elements may be treated with flame arresters, for example, sulphates of alkali or alkali-earth metals. To obtain elite types of powders after rolling fractionation of the powder elements is performed. To improve quality of powders with the minimum web thickness after the fractionation stage repeated is rolling the coarse fraction of powder particles on the rolls. Obtained gun powders have improved ballistic and operating characteristics of a gun powder with the minimum web thickness due to thermal plasticization of cellulose nitrates forming a mechanical frame of the powder elements at rolling with preliminary coating the powder elements. EFFECT: method ensures uniformity of gun powders with the minimum web thickness regardless of the used raw materials or recycled powders, versatility and process safety of the powders production for any small arms cartridges, including their elite types. 6 cl, 1 tbl, 6 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 606 418 C1 (51) МПК C06B 21/00 (2006.01) C06B 25/18 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ФОРМУЛА (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ 2015131702, 30.07.2015 (24) Дата начала отсчета срока действия патента: 30.07 ...
