PIGMENTED COMPOSITION FOR ROAD SURFACES Russian patent published in 2023 - IPC C09D133/04 C09D133/10 C09D133/08 C09D133/12 C09D5/00 

FIELD: coatings.

SUBSTANCE: invention relates to pigmented coating compositions that can be used in the construction of roads, pedestrian and parking areas, bike paths, parking lots and other facilities. A pigmented composition for road surfaces is proposed, comprising in wt.%: an acrylic copolymer having a conditional viscosity according to VZ-246 at 20± 2° C from 40 to 80 s, 5.0-15.0; amphoteric oxide of tetravalent titanium 1.0-3.0; mineral from the class of silicates 10.0-20.0; hydroaluminosilicate 0.01-1.0; multicomponent solvent, which includes functional groups: -OH; -CH₃; -O-; -COO- and C₂H₅O, 10.0-25.0; the rest is pigment 0.01-3.0; quartz filler, consisting of oxides of silicon, iron and aluminium with a fraction size of 0.1-0.4 mm.

EFFECT: expanding the scope of application of the pigmented composition, including the possibility of its use as a coating of floor surfaces inside buildings and structures, while ensuring the high quality of the resulting coating in terms of relative viscosity, adhesion, curing speed, as well as ensuring low toxicity and low fire hazard class, allowing to apply coatings inside buildings and structures.
