ANTI-FROST COMPLEX ADDITIVE AND METHODS TO PRODUCE DRY FORM OF ADDITIVE (VERSIONS) Russian patent published in 2015 - IPC C04B24/24 C04B22/08 C04B28/00 C04B111/76 

FIELD: construction.

SUBSTANCE: in this method to produce a dry anti-frost complex additive, including mixing of a plasticising component, a salt component and an intensifier of anti-frost action, the intensifier of anti-frost action is a water-soluble organic component not containing salt-producing functional groups, with the HLB value of 2.8-4.3, which is dried on a carrier - the plasticising component, and the produced powdered product is mixed with the dry salt component to produce the following content of components, wt %: plasticising component - 10-80, salt component - 10-75, intensifier of anti-frost action - 5-15. In the version of the method to produce a dry anti-frost complex additive, including mixing of a plasticising component, a salt component and an intensifier of anti-frost action, the intensifier of anti-frost action is a water-soluble organic component not containing salt-producing functional groups, with the HLB value of 2.8-4.3, which is mixed with the dry plasticising component, and the produced paste-like mass is mixed with the dry salt component to produce loose mass. The invention also relates to composition of the dry anti-frost complex additive produced by above methods.

EFFECT: lower doses of complex anti-frost additives due to increase of their technical efficiency and narrower range of recommended doses for entire temperature range of their application with provision of convenience of their transportation and storage.
