METHOD OF PRODUCING AQUEOUS EPOXY EMULSION Russian patent published in 2016 - IPC C09D5/02 C09D163/00 C09D163/02 

FIELD: technological processes.

SUBSTANCE: invention relates to method of producing aqueous emulsion of epoxy resins for use as lubricant film-forming component deposited on surface of elementary inorganic fibres (filaments) when forming complex thread during manufacturing of roving. Emulsion is obtained by direct emulsification of epoxide oligomer in aqueous solution of individual or mixed surfactants (emulsifiers) based on copolymer of acrylic polycarboxylate and polyethylene glycol and/or block copolymer of ethylene oxide and propylene oxide at following ratio of components (pts.wt): epoxy resin:acrylic copolymer and polyethylene glycol polycarboxylate:block copolymer of ethylene oxide and propylene oxide:nano-modifier (in terms of silicon dioxide):water=100:(0-10):(0-10):(0-5):(45-100).

EFFECT: invention enables to obtain stable emulsion with high colloid-chemical resistance, small size of particles (high dispersion); invention is simple and has universal method of production of emulsions.
