Abstract

The invention discloses a road marking coating containing magnesium hydroxide and a preparation method thereof. The road marking coating containing magnesium hydroxide is characterized by being prepared from, by weight, 1-3 parts of magnesium hydroxide, 1-3 parts of GdCl3, 6-10 parts of ethylene glycol, 1-2 parts of vinyl acetate, 1-3 parts of NaF, 40-50 parts of waterborne polyurethane emulsion, 3-5 parts of ethyl acrylate, 1-2 parts of potassium chloride, 1-3 parts of citric acid, 10-15 parts of titanium dioxide, 10-15 parts of blanc fixe, 10-15 parts of glass beads, a proper amount of deionized water and a proper amount of ethyl alcohol. The waterborne polyurethane coating has the advantages of saving resources, reducing pollution and being low in toxicity and environmentally friendly, and meanwhile, rare earth nanometer light-emitting materials are used for improving the light-emitting performance of the waterborne polyurethane coating, so that the coating is more suitable for being applied to road sections with the poor lighting effect, and potential safety hazards of roads are reduced; due to the addition of the magnesium hydroxide, the coating has the good flame retardant effect.

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 magnesium hydroxide 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 disperse 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 monochromaticity, 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
Based on above thinking, it is an object of the invention to provide a kind of reflective function good, strong with road adhesive force, easy construction, and there is the aqueous polyurethane road mark paint of luminescent properties.
The technical problem to be solved uses following technical scheme to realize:

B. NaF is dissolved in residue ethylene glycol solution, after stirring to clarify solution, mixes with step a gained settled solution rapidly, stir；
c. In step b gained liquid, add sodium lauryl sulphate, move in reactor, put into 20-25h in 150-200 DEG C of baking oven.
d. Take out reactor after having reacted, be cooled to room temperature, after separating with centrifuge, be filtrated to get precipitation, precipitate 3-5 time by deionized water and washing with alcohol respectively；
e. It is dried 20-25h under the conditions of step d gained is deposited in 40-80 DEG C, obtains intermediate；
F. magnesium hydroxide, titanium dioxide, blanc fixe, glass microballoon are put in ball mill ball milling uniformly after, use ethanol solution ultrasonic disperse, be dried, obtain mixture.
G., hydrotropism's polyaminoester emulsion adds step e gained intermediate, step f gained mixture and vinyl acetate, potassium chloride, ethyl acrylate, citric acid, stirs.
3. a kind of road mark paint containing magnesium hydroxide described in and preparation method thereof, it is characterised in that reactor used by step b is polytetrafluoroethyllining lining stainless steel cauldron, capacity is 15-25mL.
4. a kind of road mark paint containing magnesium hydroxide described in and preparation method thereof, it is characterised in that centrifuge speed used by step c is 5000-10000r/min, centrifugal 10-15min.
The invention has the beneficial effects as follows:Aqueous polyurethane coating disclosed by the invention has saving resource, reduces pollution, the feature of low toxic and environment-friendly, utilize Study of Nanoscale Rare Earth Luminescent Materials to improve aqueous polyurethane coating luminescent properties simultaneously, its section being more suitable for illuminating effect is bad is made to apply, reduce road safety hidden danger, pedestrian and vehicle safety are ensured, further, add the glass microballoon that reflecting effect is good, higher glistening intensity can be obtained.This coating glue viscosity is good, and ageing resistance is excellent, easy construction, less demanding to the cleaning degree of drying on road surface during construction, is generally applicable to various road surface, has good promotional value；Coordinate and with the addition of magnesium hydroxide, make coating have good flame retardant effect.
