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. ^ 2 cl, 1 ex |
