FIELD: chemistry. ^ SUBSTANCE: road marking paint contains acrylic film-forming agents, calcite filler materials - finely ground white marble and micronised calcite filler, plasticisers, organic solvents, pigments, a thickener - organically modified bentonite clays, a dispersant - mixture of natural phospholipids "soya lecithin", an anti-sedimentation agent - 20% solution of emulsion polyethylene resin in xylene "M-P-A-2000X". The acrylic film-forming agent is a thermoplastic acrylic copolymer of methyl methacrylate and butyl methacrylate and/or 48-56% solution of a copolymer of butyl acrylate, styrene and methacrylic acid in ratio (31.5-36.5): (61.5-66.5): (1.5-3.5). The paint can additionally contain barite filler - fractionated microbarite "Mibari" in amount of 0.1-5.0 pts.wt and a thickener - silicon dioxide in amount of 0.1-5.0 pts.wt. ^ EFFECT: road marking paint has resistance to alternating temperatures of 18-25 cycles while maintaining values of the rest of the properties on the same level. ^ 3 cl, 2 tbl, 15 ex |
