Abstract
The present invention relates to a novel practical luminescent material and the application thereof in plastic and paint industry. Raw materials of the luminescent materials in the prior art has the disadvantages of poorbrightness, short persistence time and short service life. The present invention adopts rare-earth aluminate photoluminescent material initial powder which is added in plastic or paint so as to manufacture luminous plastic or luminous paint. The present invention has the advantages of wide photic wavelength range, high irradiance brightness, long persistence time, stable performance, long service life, no toxicity, no harm to human bodies and no environmental pollution and is a novel practical luminescent material for environmental protection.
Description
The present invention relates to the luminescent material made with the rare earth class material, specifically, relate to that former powder with the rare earth aluminate embedded photoluminescent material prepares advanced luminescent material and in the application of plastics and coating industry.
At present, commercially available luminescent material raw material mainly contains three series products, and a class is a sulfide luminescent material; One class is a radioactive luminescent material; One class is the former powder of rare earth aluminate embedded photoluminescent material.Because the limitation of traditional luminescent material performance, as the brightness of sulfide luminescent material, time of persistence and work-ing life deficiency, and for example radioactive luminescent material is influential to environment, the purposes of luminescent material is limited to paint the label industry more, and the purposes of the former powder of rare earth aluminate embedded photoluminescent material is subjected to the influence of traditional luminescent material, is only limited to paint label industry.
The objective of the invention is to develop a kind of former powder of rare earth aluminate embedded photoluminescent material that utilizes and prepare novel practical luminescent material and the application on plastics and coating industry thereof.
Purpose of the present invention can reach by following measure: novel practical luminescent material contains former powder of rare earth aluminate embedded photoluminescent material and substrate material, substrate material is plastics or coating, according to the requirement of product to illumination effect, by weight percentage, the proportioning of rare earth aluminate and substrate material is 5～30%: select between 95～70%, wherein, coating weight per-cent is meant the weight resin in the coating.
The application of novel practical luminescent material is used for plastics and coating industry.The product of low-light (level) floodlighting was moulded shell, emergency source of electric power casing, uninterruptible power supply casing, sunshade, rain-proof fluffied, tinted shade, partition panel etc. as power switch panel, socket panel, plug, telephone set, facsimile recorder when wherein luminescent plastics was used to produce the significant illumination effect of needs or needs and does not have outer light source; With the product that is used to produce the ornamental illumination effect of generation, as mobile phone, pager casing, portable audio-visual products casing, the moulding shell, mould the system luminous pattern of stationery and sign of the luminous pattern of household electrical appliance and sign, computer cabinet, indicating meter casing, keyboard, mouse and other annex, luminous moulding, pattern and the sign of plastic crafts and can be attached to luminescent plastics pattern on the other products and member etc.
Luminous paint is used for the product surface that needs produce significant illumination effect, as the application of not having outer light illumination sign at application, night of application, power distribution cabinet, instrument box surface and the dash board of the sign of escape way, rescue path, direction, profile, the application of fire control equipment, the application of transportation equipment, the fence that do not have light illumination night, the application of baffle plate etc.; With the product that is used to produce ornamental illumination effect, as luminous moulding, pattern and the sign of wooden or other material artwork, the application of elevation of building, planar application, various fence, communal facility etc.
Luminescent plastics:
Commercially available rare earth aluminate is that fluorescence 10000 years Science and Technology Ltd.s in Beijing produce, the above former powder of 300 orders, and this raw material is used to prepare luminescent plastics and luminous paint.
Commercially available plastics are raw materials such as polyethylene, polypropylene, polycarbonate, ABS, polystyrene.The working method of luminescent plastics can adopt existing plastic processings such as injection moulding, extrusion molding, calendering, behind mould molding, can process finished product.In the preparation process of luminescent plastics, can select for use paraffin to make dispersion agent,, suitably improve processing temperature simultaneously to improve dispersion effect, higher 30～50 ℃ than the temperature that adopts the similar plastics of same processes, to improve processing characteristics.
Luminous paint:
Comprise paint in the coating, that is to say that paint is a kind of in the coating.Commercially available oiliness Clear paint, as acrylic type, polyester type, polyurethane-type varnish and other resin type oiliness Clear paint, with rare earth aluminate mutually mixing ratio be prepared from, generally should promptly join promptly and use.In preparation process, add softening agent (account for luminous paint total amount 0.5～2%) and wetting dispersing agent (account for luminous paint total amount 0.5～2%) in right amount, with the dispersion that improves luminous paint with apply effect.
The method that luminous paint can adopt spraying or brush all is coated on product surface.For guaranteeing illumination effect, the enamelled coating build generally should perhaps, according to the illumination effect requirement, be pressed the equal cloth area of the former opaque amount of rare earth aluminate finished product, the quantitative 25g/m that is controlled between 0.2mm～0.5mm
2To 250g/m
2Between.At the product surface of need coating luminous paint, carry out white primer in advance and handle, apply luminous paint again, can strengthen the luminosity of luminescent coating.On the luminescent coating surface, apply oiliness light Clear paint, can improve the coatingsurface light sensation.
The present invention has following advantage compared to existing technology: optical wavelength range is wide, luminosity is high, time of persistence is long because this luminescent material is subjected to, can absorbing wavelength at the ultraviolet ray of 300～450nm or visible light and be in excited state, when external light source disappears, this luminescent material can be got back to ground state and luminous from excited state by electronics, all exceed its luminosity and time of persistence traditional sulfide luminescent material several times, continue more than 20 hours its time of persistence in the dark; Secondly, this luminescent material does not contain any poisonous and harmful and radioactive substance, and is nontoxic to human body, and environment is not had any pollution, is the practical luminescent material of novel environment friendly, and this compares with traditional luminescent material has absolute predominance; Once more, the various physico-chemical properties of this luminescent material are very stable, long service life, after this material was subjected to light luminous for a long time, its performance did not change, and was applicable to various environment, work-ing life was above 10 years, this also is that traditional luminescent material is incomparable, so this material be widely used space and market outlook, and the luminous product made from this material is widely used in energy-saving illumination, the weak light source every field such as illumination and long-time illumination floodlight decoration of escaping.
Fig. 1: the decay of afterglow curve of the former powder of rare earth aluminate.Can obviously find out the application of three sections brightness of this material from this figure: 1, A point exists to continue exciting light sources (as black lamp), and requires the higher place of brightness; 2, AE section requires fluorescent lifetime in the AE segment limit, and requires the higher place of brightness; 3, the ED section is less demanding to luminosity, but requires the long place of fluorescent lifetime.In dark surrounds, it is 0.32mcd/m that human eye can be debated brightness
