LIGHT BINDER AND ITS USE Russian patent published in 2020 - IPC C08L53/02 C08L91/00 C08L91/06 C08L95/00 C04B24/00 C04B26/10 C08J3/20 C09D191/00 

FIELD: chemical or physical processes.

SUBSTANCE: group of inventions relates to a light binder and its use in color compositions in certain areas of road construction and/or industry. Light binder contains, wt %: (i) 45 to 70 plasticiser, consisting of oil with total content of paraffin compounds, measured according to ASTM D2140, at least 50 wt %, (ii) from 20 to 50 of a structure-forming agent selected from petroleum-derived hydrocarbon resins and vegetable-derived resins made from vegetable and/or plant cultures, (iii) from 1 to 7 of at least one block copolymer based on butadiene links and styrene links, having average molecular weight from 50000 to 200000 daltons, and (iv) optionally from 0.05 to 0.5 of the surfactant relative to the weight of the light binder. Described also is a method of producing a light binder, a composition for making surface layers or cold-laid asphalt concrete mixtures, asphalt-concrete mixture containing a light binder, as well as use of a light binder and a composition.

EFFECT: technical result is providing a light binder with low viscosity, more resistant to low temperatures.
