Technical field
The present invention relates to a kind of marking paint, belong to paint field, particularly relate to a kind of road mark paint containing nano-calcium carbonate and preparation method thereof.
Background technology
Roadmarking is used for guiding traffic, is to improve traffic safety, ensure the unimpeded important infrastructure of road traffic.China is stepping up traffic infrastructure level, construction of modern road network, simultaneously being continuously increased along with vehicle, road load and graticule abrasion and is constantly increasing the weight of, and these all illustrate that Current traffic gage mark coating has huge market demand.
Wherein water paint is a kind of relatively new type coating on Coating Market, and for more traditional solvent-based paints coating, water paint is with water as solvent, during producing and using
VOC is well below solvent-based paints, little to human injury, and therefore, water paint is more saved resource, reduced pollution, low toxic and environment-friendly.Progressively replace solvent-based paints coating to represent the developing direction of coating industry with water paint.
Aqueous polyurethane is to replace organic solvent as the new polyurethane system of decentralized medium using water, amido-containing acid ester base, urea bond and ionic bond in its molecular structure, cohesive energy is high, cohesive force is strong, and can be by changing the short proportion adjustment polyurethane performance with soft or hard section of soft segment length, so, exploitation aqueous polyurethane marking paint is a good selection.Wu Mingjiang utilizes the Material synthesis such as waterborne polyurethane resin and blanc fixe a kind of white marking paint in the development of aqueous polyurethane marking paint, but reflective function is the most superior, do not possesses luminescent properties simultaneously, limit it in dark location, such as freeway tunnel, and the application of driving in evening.
Rare earth element show because of the electronic structure of its uniqueness excellent monochromaticjty, anti-light Bleachability, fluorescence lifetime length and
The characteristics such as Stocke displacement is big and have a wide range of applications in fields such as materials.Rare earth luminescent material has luminosity height, length persistence not available for other luminescent material, wavelength of transmitted light is adjustable, the radiationless advantage such as pollution-free, receives the extensive concern of people about its research applied.
Summary of the invention
