WEAR-RESISTANT PAINT FOR ROAD MARKING Russian patent published in 2011 - IPC C09D133/00 B82B3/00 

FIELD: chemistry.

SUBSTANCE: wear-resistant paint for road marking contains an acrylic film-forming agent, a plasticiser, organic solvents, a mixture of pigments and filler materials. The mixture of pigments and filling materials consists of three fractions, the particle sizes D₁, D₂ and D₃ of which satisfy the relationships: D₁/D₂=2.4-3.3 D₁/D₃=8.5-8.9, and volume concentration of fractions V₁=51-53.0%; V₂=7.0-8.0%; V₃=0.8-1.2%. The first and third fractions include filler materials, the second fraction includes pigments, and particles of the third fraction are nanosized.

EFFECT: invention increases abrasive wear-resistance of the paint and creates the effect of reinforced structures.
