Abstract
The invention discloses a low-hazard hot melting reflective coating. The reflective coating is prepared from the following raw materials in parts by weight: 500-650 parts of petroleum resin, 2-6 partsof polyethylene wax, 200-300 parts of titanium dioxide, 20-35 parts of a plasticizer, 80-120 parts of stone powder and 20-35 parts of glass beads, wherein the petroleum resin is used as a base material, the polyethylene wax is used as a compound dispersant, the titanium dioxide is used as a coloring agent, the stone powder is used as an auxiliary material, and the glass beads are used as a reflective material. The domestic commonly used cheap chemical building materials are used as main raw materials, so that the raw materials are easy to obtain, and the cost is low; furthermore, the manufacturing process is simple, and the manufacturing cost is low; the whiteness, wear resistance, compressive strength and rapid moisture-releasility of the reflective coating provided by the invention aresuperior to that of solvent based coatings; after the reflective coating is painted for 1-3 min, the coating is dry, and vehicles can pass through; construction can even be carried out without blocking traffic; the coating line is complete and clear, has distinctive edges and corners, is high in sharpness, is three-dimensional, and has a good reflection effect; the reflective coating is free fromvolatile components, and is safe and non-toxic.
Description
technical field [0001] The invention relates to a heat-melt reflective paint, in particular to a low-harm heat-melt reflective paint. Background technique [0002] There are two types of road marking paints: solvent-based and hot-melt. Solvent-based coatings have a large amount of organic solvents volatilized during production and use, which pollutes the environment, affects people's health, and is prone to fire accidents. Moreover, the coatings have low strength, are not wear-resistant, and have a short service life. Although the hot-melt road sign reflective coating has the advantages of fast drying, wear resistance, good day and night visibility, and long service life, it still has some disadvantages: First, the quality of domestic petroleum resin and titanium dioxide used in it is not good enough, and the color is relatively poor. Heavy, which affects the whiteness of the coating, and the cost is higher if imported raw materials are used; second, the hot-melt road marki...
