METHOD TO MANUFACTURE COATING Russian patent published in 2012 - IPC C09D175/04 E01C13/06 E01C13/10 E01C15/00 

FIELD: construction.

SUBSTANCE: method to manufacture a coating includes preparation of a mixture by means of mixing of a filler from rubber crumb and a binder based on polyurethane. Simultaneously and separately from each other mixtures are produced for basic and upper layers, at the same time in the mixture for the basic layer they use a filler from rubber crumb with fraction of 2-12 mm, and in the mixture for the upper layer they use a filler from rubber crumb with fraction of 1-3 mm and a pigment dye. In process of mixture mixing for its upper layer it is compacted, afterwards the mixture for the upper layer is serially discharged into a die mould, then the mixture for the basic layer is discharged, and pressed under pressure with the help of a press, then maintained until full hardening, and the produced coating is discharged from the die mould.

EFFECT: high efficiency of coating manufacturing, higher reliability and durability of a coating, possibility to manufacture a double-layer coating with damping properties.
