SHELLAC COATED PARTICLE OF ACTIVE INGREDIENTS WITH CONTROLLED RELEASE PROPERTIES AT HIGH PH VALUES, METHOD OF THEIR PRODUCTION AND THEIR USE

摘要

FIELD: chemistry.;SUBSTANCE: group of inventions refers to a coated particle of active ingredients, a method for its production and use as an additive to building mixtures, dry mortars, cement mortars and/or concretes. A coated particle of active ingredients with controlled release properties at pH values of 10 to 14, the particle has a coating that contains, at least, two layers in the form of a core/shell structure, where the active ingredient is contained in the core space, and where the active ingredient is selected from one or more chemical additives for construction works to regulate inorganic binders, and the coating contains crosslinked shellac.;EFFECT: development of additive-accelerator with the properties of controlled release.;14 cl, 12 dwg
