INTEGRATED modifying agent for gypsum and composite binders, dry mixes and method of preparation

摘要

1. Integrated modifying additive for gypsum and composite binders, construction mixtures, characterized in that, in order to increase efficiency of complex additives simplify preparation and reduce its consumption, lower energy costs for its preparation, dimensional stability obtained gypsum materials, increasing setting time and hardening, decrease caking of suspensions of composite particles of dry mixes, as well as to simplify the preparation of the additive, the survivability of mortars and concretes, it contains the alkali powder Component: a defoamer; retarders and hardening; sodium tripolyphosphate and ester polycarboxylate and sodium polycarboxylate with different branching chains of hydrophobic organic radicals with the following component ratio, wt.%: 2. A method for preparing an integrated additive, characterized in that, in order to increase its efficiency, the additive components, except the ester polycarboxylate «Kelong R 209 'and the sodium polycarboxylate are pretreated attritor - disintegrator for 2 min; to a homogeneous mixture of components is added with stirring for 2 minutes, said ether polycarboxylate and sodium polycarboxylate; Additives Dosage is performed in an amount of 0.4-0.8% by weight of the gypsum binder.
