Abstract

The invention discloses an environment-friendly hot-melt marking coating and a preparation method thereof, and belongs to the technical field of environment-friendly hot-melt marking coatings. The environment-friendly hot-melt marking coating is prepared from, by weight, 13-15 parts of modified C5 petroleum resin, 6-8 parts of a pigment, 27-29 parts of quartz sand, 26-28 parts of ground calcium carbonate, 1-3 parts of castor oil, 2-4 parts of polyethylene wax, 1-3 parts of powdered acrylonitrile-butadiene rubber and 20-23 parts of glass beads. The invention also discloses a preparation methodof the environment-friendly hot-melt marking coating. The environment-friendly hot-melt marking coating has the advantages of good fluidity, high compressive strength, short drying time, high softening point, good flexibility, water resistance, acid and alkali resistance, good light reflection performance and the like.

Description

technical field [0001] The invention relates to an environment-friendly hot-melt marking paint and a preparation method thereof, belonging to the technical field of hot-melt marking paint. Background technique [0002] The road performance of road traffic marking materials not only affects road maintenance and maintenance costs, but also directly affects traffic safety. Road marking paints on the market can usually be divided into two categories: solvent-based and hot-melt. Solvent-based marking paint releases a large amount of solvent during use, pollutes the environment, and the paint film takes a long time to dry and has poor wear resistance, so it usually only lasts for about 3 months. Hot-melt marking paint has the characteristics of excellent durability, quick drying, good visibility at night and no solvent. Therefore, it has received extensive attention since its inception, and its usage has increased year by year. [0003] With the rapid development of road traffic...
