Abstract

The invention belongs to the field of paint, and discloses a preparation method of rare earth noctilucent paint for a road traffic sign board. The formula of the rare earth noctilucent paint comprises components in percentage by weight as follows: 35%-55% of epoxy resin, 12%-22% of low-etherification melamine resin, 1%-3% of butanol, 1%-3% of xylene, 3%-8% of a silicone oil solution, 15%-20% of white color paste and 8%-15% of luminescent color paste. The preparation method of the rare earth luminescent material comprises the following steps: alkaline earth aluminate is taken as the substrate, the rare earth EU2+ is doped and used as an activator, medium-heavy rare earth ions such as Dy3+ or Nd3+ and the like are added to serve as auxiliary activators, the doped EU2+and substrate ions can have effective energy transfer, so that when the luminescent material is irradiated/activated by ultraviolet light or near ultraviolet visible light, the alkaline earth aluminate substrate can transfer absorbed light to doped lattice EU2+ which is activated for luminescence, and the paint has the advantages of long absorbed light waveband and long afterglow time.

Description

RE luminous road and traffic sign plates coating and preparation method thereof

Technical field

The invention belongs to paint field.

Background technology

Paint is the call in coating ancient times; Coating, is modern civilization address, comprises more scientific and technological composition, be widely used in modern science and technology and industrial circle.Paint comes with organic or inorganic material with decoration and a kind of mixture protecting article.B.C. 6000, China with mineral compound and pigment dyestuff baking mixed to paint improved.B.C. 1500, in France and Hispanic cavern, paint was for drawing and decoration.B.C. 1500, Egyptian's dyestuff such as indigo and madder manufactured blue and red pigment, but this paint is still far from perfect.In 18th century, due to the exploitation to Semen Lini oil and zinc oxide, paint industry is developed rapidly.20th century, painting technology has had significant development, having occurred that clinging power paint that is larger, higher, fire-retardant, the anticorrosive shades of colour high with thermostability of glossiness paints large is in early days main raw material mainly with vegetables oil, therefore is called " paint ", as the boiled wood oil of health environment-friendly ecosystem.No matter the coating products of to be traditional with crude substance be raw material, or in modern development to synthesize the coating products that Chemicals are raw material, all belong to organic chemical industry's macromolecular material, the film formed belongs to macromolecular compound type.The classification of the Chemicals of passing through according to the modern times, coating belongs to fine chemical product.Modern coating is progressively becoming the polyfunctional engineering materials of a class, is an important industry in chemical industry.Road signs are graphical symbols of display traffic law and road information, it can make traffic law obtain image, concrete, simple and clear expression, also have expressed the content be difficult to by text description, in order to the direction of traffic that regulates the traffic, indicates to ensure the facility of the coast is clear and traffic safety simultaneously.Be applicable to highways and streets and all accommodation roads, have the character of decree, vehicle, pedestrian must observe.China's road and traffic sign plates major part is non-luminous sign panel, and this brings very large inconvenience to driving at night, so invent a kind of luminous sign panel coating is and urgent thing.

Summary of the invention

The preparation method of RE luminous road and traffic sign plates coating: (1) fills a prescription: it consists of by weight percentage: epoxy resin: 35% ~ 55%, low etherify melamine resin: 12% ~ 22%, butanols: 1% ~ 3%, diformazan is stupid: 1% ~ 3%, silicon oil solution: 3% ~ 8%, white colorant: 15% ~ 20%, luminous mill base: 8% ~ 15%; (2) preparation method of rare earth luminescent material: take alkaline earth aluminate as matrix, mix rare earth elements europium (Eu2+) as activator, and Heavy rare earth makes auxiliary activator in adding dysprosium Dy3+ or neodymium Nd3+ etc., due to can effective transmission ofenergy be there is between doping Eu2+ and matrix ion, when luminescent material is by UV-light or near ultraviolet radiation of visible light (exciting), alkaline earth aluminate base status can by the Light energy transfer of absorption to the Eu2+ mixing lattice, make it to be stimulated and luminous, its advantage is that absorb light wave band is long, and time of persistence is long.

Claims
