THERMOFLEXIBLE PLASTIC COMPOSITION - SPRAY-PLASTIC FOR A HIGHWAY BED TRAFFIC-BEARING SURFACE MARKING BY SPRAYING UNDER PRESSURE Russian patent published in 2003 - IPC

FIELD: road-building. SUBSTANCE: the invention presents a thermoflexible plastic composition - a spray - plastic used for a highway bed asphaltic concrete pavement surface traffic signs marking by spraying under pressure. The composition besides a film-forming component - polyester resin containing up to 55 mass. % of terephthalic acid with softening temperature of no less than 70 C, a plasticizer composed of a mixture of polyester resin based on aliphatic diatomic acids and aliphatic glycols and a product of decomposition of polyethyleneterephthalate by ethylene glycol, titanium dioxides, an antisedimentation additive, a mineral filler, - additionally contains surfactants and wax. EFFECT: the combination of components in a definite ratio allows to reduce viscosity of a material melt, to increase its strength and to reduce abradability. 1 cl, 1 tbl, 3 ex
