Marking paint

Abstract

The invention discloses a marking paint which comprises the following components by weight: 2-3 parts of phthalic anhydride, 1-3 parts of PE resin, 10-20 parts of calcium carbonate, 5-15 parts of a talcum powder, 5-10 parts of bentonite, 15-25 parts of industrial ethanol, 15-25 parts of titanium dioxide, 5-15 parts of glass beads, 1-2 parts of phenoxy ethanol, 30-40 parts of precipitated barium sulfate, 1-2 parts of a defoaming agent, 15-20 parts of EVA, 1-3 parts of xylene, 5-10 parts of ethylene propylene, and 5-10 parts of tung oil. The 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 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 in a dark night or under a weak-light weather, the marking paint has high identifiability and convenient use.

Description

[0001] technical field [0002] The invention relates to a paint, in particular to a road marking paint. Background technique [0003] 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 [0004] The technical problem to be solved by the present invention is to provide a road marking paint that does not need heating, dries quickly and has good...

[0003] 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 night recognition is poor, and it cannot play a security role for pedestrians and drivers traveling at night

In addition, the hot-melt marking paint is quick-drying and wear-resistant, but it needs to be heated during the construction process, so it is not suitable for construction in cold areas
