Abstract
The invention discloses a waterproof anti-corrosion traffic sign noctilucent material and a preparation method and application thereof. The waterproof anti-corrosion traffic sign noctilucent material is prepared from 30-45 wt% of hydrophobic film-forming agent, 10-20 wt% of rare earth doped alkaline-earth metal aluminate long-lasting phosphor material, 10-15 wt% of organic solvent, 5-15 wt% of gaseous phase nano-silica and the balance organic bentonite anti-settling agent. The waterproof anti-corrosion traffic sign noctilucent material is free of toxicity and radioactivity and stable in chemical performance, can shine automatically and continuously after absorbing all kinds of visible light such as daylight, lamplight and environment stray light, can stop hydrolysis of most of the rare earth doped alkaline-earth metal aluminate long-lasting phosphor material after making contact with water and being corroded so that the rare earth doped alkaline-earth metal aluminate long-lasting phosphor material can shine continuously, and has good waterproofness and corrosion resistance.
Description
Technical field
The invention belongs to field of light emitting materials, relate in particular to the anti-corrosion traffic mark noctilucent material of a kind of waterproof and preparation method and application thereof.
Background technology
Road traffic mark is the graphical symbol of display traffic law and road information, it can be vivid, concrete and simple and clear expression traffic law, also can express the content be difficult to by text description, in order to regulate the traffic and to indicate direction of traffic, to ensure the facility of the coast is clear and traffic safety simultaneously.The road traffic mark majority of current use is coated with reflection-type coating, does not generally have noctilucent function.But if without street lamp on road, this kind of passive reflection-type traffic mark can only play a role to having the vehicle of illuminations night, its effect then substantially can not be played for without the pedestrian of illuminations and cyclist.Therefore, the noctilucence traffic mark coating of active illuminant is very important.As traffic mark luminescent coating, need long-term exposure in rainwater, under moist environment, require very high to the water-repellancy of coating and solidity to corrosion.Current noctilucence traffic mark is generally directly be coated on road by phosphorescent coating to form, and with the addition of rear-earth-doped alkali earth metal aluminate long after glow luminous material in phosphorescent coating and be very easily hydrolyzed with the steam in rain water and air, make noctilucence traffic mark lose guide elicitation effect.With rear-earth-doped alkali earth metal aluminate long after glow luminous material SrAl

3↑, this reaction can generate aluminium hydroxide, and the pH value of system is raised, and has both destroyed the crystalline structure that luminescent powder is original, have impact on again the acid base equilibrium of system.Under the impact of rainwater and moisture, the luminous intensity of rear-earth-doped alkali earth metal aluminate long after glow luminous material declines at least 50%, even completely not luminous.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of anti-corrosion traffic mark noctilucent material of waterproof containing rear-earth-doped alkali earth metal aluminate long after glow luminous material and preparation method and application thereof.
The object of the invention is to be achieved by following technical proposals.
The anti-corrosion traffic mark luminescent coating of a kind of waterproof, be made up of the raw material of following weight percents: hydrophobic film-forming agent is 30-45wt%, rear-earth-doped alkali earth metal aluminate long after glow luminous material is 10-20wt%, organic solvent is 10-15wt%, gas phase nano silicon-dioxide is 5-15wt%, and surplus is organobentonite anti-settling agent; Wherein, described organic solvent is the mixture of dimethylbenzene, ethyl acetate and butanols, described hydrophobic film-forming agent is the mixture of silicone resin, organic fluorine and acrylic resin or organic fluorinated silicone modified acrylic resin, and described rear-earth-doped alkali earth metal aluminate long after glow luminous material is SrAl

3+by mass, in described organic solvent, the ratio of dimethylbenzene, butanols and ethyl acetate is (4-35): (4-35): 1, and in described hydrophobic film-forming agent, the ratio of silicone resin, organic fluorine and acrylic resin is (0.2-0.5): (0.2-0.5): 1.
In technique scheme, hydrophobic film-forming agent is 35-40wt%, and rear-earth-doped alkali earth metal aluminate long after glow luminous material is 13-17wt%, and organic solvent is 12-14wt%, gas phase nano silicon-dioxide is 7-13wt%, and surplus is organobentonite anti-settling agent.
In technique scheme, the particle diameter of described gas phase nano silicon-dioxide is 5-50 nanometer.
In technique scheme, by mass, in described organic solvent, the ratio of dimethylbenzene, butanols and ethyl acetate is (20-30): (20-30): 1.
The preparation method of a kind of above-mentioned waterproof is anti-corrosion traffic mark luminescent coating, at room temperature 20-25 DEG C, hydrophobic film-forming agent, rear-earth-doped alkali earth metal aluminate long after glow luminous material, organic solvent, gas phase nano silicon-dioxide and organobentonite anti-settling agent are mixed in proportion to evenly, namely obtain the anti-corrosion traffic mark luminescent coating of waterproof.
In technique scheme, hydrophobic film-forming agent is 35-40wt%, and rear-earth-doped alkali earth metal aluminate long after glow luminous material is 13-17wt%, and organic solvent is 12-14wt%, gas phase nano silicon-dioxide is 7-13wt%, and surplus is organobentonite anti-settling agent.
In technique scheme, the particle diameter of described gas phase nano silicon-dioxide is 5-50 nanometer.
In technique scheme, by mass, in described organic solvent, the ratio of dimethylbenzene, butanols and ethyl acetate is (20-30): (20-30): 1.
A kind of above-mentioned waterproof is anti-corrosion traffic mark luminescent coating is as the application of indication light body, the anti-corrosion traffic mark luminescent coating of waterproof described in road surface even application or brushing multilayer, wherein, often spraying or after brushing the anti-corrosion traffic mark luminescent coating of waterproof described in one deck, solidifies little for this layer of waterproof anti-corrosion traffic mark luminescent coating layer dry 0.5-6 at 20-80 DEG C up to waterproof anti-corrosion traffic mark luminescent coating layer.
