Abstract

The invention discloses a scraping-type two-component road marking paint and a preparation method thereof, relating to the technical field of transportation paints, comprising A component with a mass fraction of 57.45% and a B component with a mass fraction of 42.55%. The components are formulated according to the following mass fractions: 45-55% of modified epoxy resin, 5-10% of pigment, 35-40% of filler, 0.5-1% of auxiliary agent, and 0.2-0.7% of thixotropic agent; the B group According to the following mass fraction formula: 30-40% epoxy curing agent, 10-15% pigment, 50-55% filler, 0.5-1% additive, 0.2-0.7% thixotropic agent; the A component and Component B is uniformly mixed according to the mass ratio of 1‑1.5:1. The scraping type two-component epoxy marking paint produced by the invention has strong adhesion to road surfaces and glass beads, good wear resistance and water resistance, long service life, low maintenance cost, high solid content, and is healthy for construction workers. No impact, fast curing.

Description

Technical field: [0001] The invention relates to the technical field of transportation coatings, in particular to a scraping type two-component road marking coating and a preparation method thereof. Background technique: [0002] Road pavement markings play a vital role in regulating and guiding the safe and orderly circulation of pedestrians and vehicles, especially in unfavorable environments such as night and rainy days, so the continuous brightening of road markings and continuous excellent retroreflectivity are particularly important important. Hot-melt road marking materials have high solid content, fast drying, and convenient construction, and have been widely used. With the improvement of technology, the mechanical properties have also been greatly improved. However, due to the characteristics and defects of thermoplastic resin materials, hot-melt marking paint and The adhesion of glass beads is poor. Under the action of tire friction, the glass beads on the surface...
