Application analysis of water-based reflective road marking paint

Jun 04, 2020

   At present, foreign road marking paints are highly water-based and develop rapidly. Over 90% of road marking paints in developed countries such as the United States, Germany, Spain, Sweden and Finland use water-based products. Due to the early start of road marking paints abroad and the rapid development of technology, nano road marking paints, two-component road marking paints, and road coatings with pigment coatings have appeared.

       A few months or even a few days after production, there will be large changes in viscosity, surface skinning and other phenomena, resulting in poor paint sprayability and poor opening effect; the non-sticking time cannot meet the actual requirements of road construction, affecting construction Smooth traffic at all times.

      There are more than 100 road marking paint production plants in China, and several large factories with strong technical strength have also begun to produce water-based road marking paints. The Ministry of Communications has formulated relevant industries to ensure the quality of road marking paints. Standard, is vigorously promoting water-based road marking paint. Analysis of floor coating experts: With the development of China's road transportation industry and the sharp increase in car ownership, the demand for marking paint will soar. A lot.

  Our country's water-based road marking paint products have been used in airport, highway and other engineering construction, which also exposed some technical bottlenecks. The current problems of water-based reflective road marking paint include: poor wear and weather resistance, need to be repainted at intervals of 1a; poor water resistance and alkali resistance, which cannot meet the actual requirements of road water soaking; Affects the retroreflective coefficient to reduce the reflective effect; poor storage stability.
