COMPOSITION FOR PRODUCTION OF BUILDING COATING AND METHOD OF ITS APPLICATION Russian patent published in 2014 - IPC C08L97/02 C04B28/30 C04B41/50 

FIELD: construction.

SUBSTANCE: composition for obtention of building coating and products contains filler and magnesian binder - sludge of carnallite chlorates. According to the invention, in order to enable the possibility of rapid application of composition mixed with water, on the coated surface, fluff pulp and / or fluff wood sawdust is used as a filler in relation filler to binder from 30/70 to 80/20%. Method for applying the composition on the surface, comprising mixing of composition with water in the spray water process through the air mixture of the filler and binder forming the composition, is proposed. For the preparation of composition, the cellulose cotton or fluff wood sawdust in dry form is mixed with crushed sludge of carnallite chlorates. At the mounting place of blowing machine the mixture is fed through the hose by means of air, at the downstream end of which there is a tip with nozzles, spraying water under high pressure. By wetting the mixture sticks to any surface due to excellent adhesion of binder. Optimum amount of water is about 50% from weight of magnesia binder. At least 20% of water is needed for reaction of the binder, and at more than 150%, the applied coating dries for too long.

EFFECT: invention makes it possible to expand the resource base and reduce manufacturing costs.
