Abstract

The invention relates to a hot melt coating for road sign and a preparation method thereof, and belongs to the technical field of polymer materials. The coating provided by the invention comprises the following raw materials by weight: 50-70 parts of petroleum resin, 5-10 parts of tackifier resin, 10-20 parts of polyester resin, 5-15 parts of silicone resin, 6-17 parts of soya-bean oil alkyd resin, 8-15 parts of phenolic resin, 3-12 parts of aluminum metaphosphate, 5-10 parts of titanium dioxide, 30-50 parts of calcium carbonate and 10-20 parts of hollow glass microspheres. The hot melt coating for road sign provided by the invention can effectively enhance the wear resistance and weather resistance of the coating, improves the adhesion stress of the coating with the pavement and prolongs the service life of the coating.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof. More specifically, the invention relates to a hot-melt coating for road signs and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] The hot-melt coating for road signs has a fast coating construction speed and can be used in about 0.5 hours after coating construction. It has the advantages of thick coating, friction resistance, durability, no organic solvent, and environmental friendliness. Hot-melt coatings for road signs are currently the most widely used coatings on highways and urban traffic roads. [0003] On May 25, 2009, the State Intellectual Property Office published an invention patent with the publication number CN101372598 and the name "Energy Storage Self-luminous Road Marking Paint". This patent discloses an energy storage self-luminous road marking paint, which features The ratio of raw materials by weigh...
