Abstract
The present invention discloses a high temperature luminescent glaze, a processing technique thereof and the application thereof in the production of luminescent ceramic tiles. The luminescent glaze is prepared from the following components: 50 to 68 wt% of SrAl2O4EuDy (alkaline earth aluminate), 25 to 40 wt% of SiO2, 4 to 6 wt% of Al2O3, 1.5 to 3.0 wt% of CaO, 0.5 to 1.0 wt% of MgO and 0.1 to 0.8 wt% of Fe2O3. The luminescent glaze is produced by processes of mixing, grinding, high temperature calcination and melting, pulverization, finished product obtainment, etc., and the luminescent glaze can be used for producing luminescent ceramic tiles. The luminescent glaze does not contain substances harmful to human bodies, harmful substances can not be generated in the use process, and thereby, harmlessness to human bodies and environment in the use process is avoided. The produced luminescent ceramic tiles have less light absorbing time and much afterglow time and have high adaptive capacity to special weather and environment.
Description
Technical field
The present invention relates to a kind of production technology and the application on the production luminous tiles thereof of luminescent material technology, particularly a kind of luminescent glaze.
Background technology
The existing luminous product that is used for caution at night or prompting, though various in style, change ten thousand times without leaving the original aim or stand, all be unable to do without the most basic luminescent material, this material mostly is sulfide luminescent material, and is added with a spot of radiation, thereby easily produces radiocontamination; Simultaneously, because the existence of sulphur tends to produce obnoxious flavour in production and use,, thereby cause damage for human body and environment as sulfurous gas and other sulfide; In addition, sulfide luminescent material easily decomposes under the light long-term irradiation, and its poor stability through secular use, can not keep stable illumination.
In addition, above-mentioned existing luminescent material is unfavorable for making production fire-retardant or that do not fire product because himself characteristic majority only can be applied on plastics and the organic material, meets the warning sign or the nameplate of fire-fighting requirement as production; Though also the someone attempts luminescent material is used for pottery to satisfy the requirement of fire-fighting, because pottery needs high-temperature firing, fires through secondary, luminous pigment is easy to loss of gloss, and Here it is will produce the main difficult technical that luminescent ceramic will overcome.
Summary of the invention
The objective of the invention is effectively to overcome new type high temperature luminescent glaze and the complete processing thereof that the problems referred to above take place in order to provide a kind of, with and application on the production luminous tiles, its good luminous performance, time of persistence is long, the brightness height, do not have toxic side effect and radioactivity, simultaneously, successfully solved the technical barrier that the luminescent material secondary is fired easy loss of gloss.
The object of the present invention is achieved like this:
1, the high temperature luminescent glaze by weight percentage, it is made of following component:
SrAl
2O
4EuDy?50-68％，SiO
2?25-40％，Al
2O
3?4-6％，CaO?1.5-3.0％，MgO?0.5-1.0％，Fe
2O
3?0.1-0.8％。
2, the complete processing of above-mentioned high temperature luminescent glaze comprises following content:
A. mixed grinding
After each component mixing described in above-mentioned 1, placed the ball milling mix grinding 6 hours, and 325 orders that sieve;
B. high heat burnout
Burn till frit on the shuttle-type stove that places the oxygen barrier makeup to put the luminescent glaze of above mix grinding, firing temperature is 800-1000 ℃, firing time 3-6 hour;
C. pulverize finished product
Above-mentioned luminous glaze frit powder is broken into 325 orders makes powdery;
3, the application of above-mentioned high temperature luminescent glaze on the production luminous tiles
A. be modulated into China ink
Be modulated into printing ink according to following ratio; Luminescent glaze 75-85%, olibanum oil 8-15%, white oil of camphor 6-12%;
B. silk screen printing
The printing ink that to make by luminescent glaze with 100 order silk screen printings at ceramic tile surface;
C. glazing is fired
It is 1.0-1.8mm glaze layer that the high temperature luminescent glaze is formed thickness by 80 purpose silk screens at the ceramic tile surface by the B gained, places then on the rod formula kiln and burns till 3-5 hour, and firing temperature is 800-1000 ℃, and the product glaze of coming out of the stove is as bright as a sixpence.
In sum, high temperature luminescent glaze essentially consist of the present invention is an alkaline earth aluminate, does not contain the material of any harmful human body, also can not produce any objectionable impurities in the use, thereby causes damage for human body and environment.When the production luminous tiles, on the luminescent material alkaline earth aluminate, form protective layer, the oxygen barrier heating under vacuum makes both 1000 ℃ of abilities of this material, does not destroy its peculiar activity again.Luminescent material through the oxygen barrier heating under vacuum has stronger activity, thereby absorbing time is shorter, and time of persistence is longer to have better adaptive faculty to special climate and environment.
