Abstract

The invention discloses a production process of hot-melt reflective coating for durable pavement markings. A formula comprises water-based polyurethane resin, perchloro-ethylene resin, rutile type titanium dioxide, glass beads, a plasticizer, nano talcum powder, an environment-friendly colored mixed-phase inorganic pigment and a plant pest-control bacteriostatic agent as raw materials for performing preparation, wherein the water-based polyurethane resin accounts for 25-30 parts by weight as a base material, the perchloro-ethylene resin accounts for 22-25 parts by weight as a dispersing agent,the rutile type titanium dioxide accounts for 8-12 parts by weight as a coloring agent, the glass beads account for 5-8 parts by weight as a reflective agent, the plasticizer accounts for 2-5 parts by weight, the nano talcum powder accounts for 5-8 parts by weight as an auxiliary material, the environment-friendly colored mixed-phase inorganic pigment accounts for 10-20 parts by weight as a durable agent, and the plant pest-control bacteriostatic agent accounts for 2-4 parts by weight. The hot-melt reflective coating for durable pavement markings has extremely high endurance and excellent infrared reflection function and UV resistant function, effectively avoids damage of the sunlight on the pavement markings, prevents pests from corroding and biting the markings, and further improves thedurability of the hot-melt reflective coating.

Description

Technical field [0001] The invention relates to a production process of hot-melt reflective paint, in particular to a production process of hot-melt reflective paint for durable road markings. Background technique [0002] Road markings are divided into: hot melt markings, cold paint markings at room temperature, color non-slip markings, oscillating non-slip reflective markings and preformed markings. The principle of the reflective marking line is to add a reflective material to the paint to play the role of marking to form a convex reflective marking line on the road surface. Due to long-term exposure to multiple factors such as wind and sun, insect bites and ageing, road markings will gradually fade until they disappear. Under such circumstances, a durable road marking reflective paint is needed to avoid this phenomenon. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a durable road marking hot-melt refl...
