Road marking paint

Abstract

The invention discloses a road marking paint which comprises the following components by weight: 20-30 parts of acrylic resin, 1-3 parts of PE resin, 10-20 parts of calcium carbonate, 5-15 parts of kaolin, 5-10 parts of bentonite, 15-25 parts of industrial ethanol, 5-15 parts of titanium dioxide, 5-15 parts of glass beads, 1-2 parts of phenoxy ethanol, 0.5-1.5 parts of diisooctyl phthalate, 2-5 parts of toluene, 1-3 parts of xylene, and 5-10 parts of epoxy resin. The road marking paint disclosed by the invention has good wear resistance, good weather resistance and good acid and alkali resistance; a paint film has good adhesive force to the road surface, is resistant to impact, and does not easily generate discoloration, fracturing, stripping and other phenomena; while in use, the road marking paint can be subjected to direct spray coating or rolling coating, has convenient construction, is rapidly dried, and does not need heating; and the glass micro-beads adhered on the surface of the paint film can improve the visibility of traffic markings, and identifiability is high in a dark night or under a weak-light weather.

Description

technical field [0001] The invention relates to a paint, in particular to a road marking paint. Background technique [0002] At present, domestic marking paints are mainly thermoplastic solvent-based marking paints. Solvent-based marking paints will volatilize a large amount of VOC harmful substances during the drying process, causing great pollution to the surrounding environment. Also, the reflective performance is weak, and it does not have luminous performance when there is no light source, so the nighttime recognition is poor, and it cannot play a safety role for pedestrians and drivers traveling at night. In addition, hot-melt marking paint is quick-drying and wear-resistant, but it needs to be heated during construction, so it is not suitable for construction in cold areas. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heat-free road marking paint with good wear resistance. [0004] The present inve...
