A kind of photic light ceramic brick and production method thereof held
Technical field
The invention belongs to the preparation field of architectural pottery product, be specifically related to a kind of photic light ceramic brick and production method thereof held.
Background technology
Photic light-storing material is called again light storage type self luminous material, on-radiation light-storing material, non-transformer self-luminescent material etc.This material was initiatively inhaled visible rays such as holding sunshine, light, ultraviolet light, veiling glare after 5~10 minutes, just can continue in the dark luminous 6-8 hour, and can according to actual needs, make it send the multiple colouramas such as red, green, blue, Huang, purple.Due to its distinctive high brightness, fast extinction, the long good physicochemical properties such as light that hold, making it be widely used in the every field such as architectural decoration, communications and transportation, security against fire, electronic communication, electric apparatus, instrument and meter, petrochemical industry, subway tunnel, printing printing and dyeing, advertising board, bullion, is extremely rising decorative hair luminescent material of 21 century.
The sign made from photic light-storing material, can be widely used in road caution sign, prohibitory sign, Warning Mark, tourist district's sign, road construction safety sign and facility, changeable-message sign, people can clearly recognize in the weather of dark, foggy, bad weather, reduce the incidence of traffic accident, make the guiding of highway communication more convenient, thoughtful.Photic light-storing material is a kind of luminescent material of Intelligent energy-saving, its not electricity consumption, and equipment that need not be complicated, does not generate heat, can not cause fire, utilizes the sunlight on daytime and the light at night to hold light; Night automatic luminous, completely without manual operation.
The photic light-storing material great majority that use for safety sign on the market at present adopt the resin paste that contains transparent resinous principle and light-storage luminant pigment ingredient and form light-storage luminant layer, the transparent resinous principle that coordinates 95% weight of total amount in resin paste, above-mentioned material is as the uses such as mark of road, and abrasion performance, weatherability, chemical resistance are all poor.
Summary of the invention
In view of the deficiencies in the prior art, the object of the present invention is to provide a kind of photic light ceramic brick and production method thereof held, be intended to solve existing photic light-storing material abrasion performance, weatherability, the poor problem of chemical resistance.
For achieving the above object, the technical solution used in the present invention is as follows:
The photic light ceramic brick that holds is made photic luminescence glass layer by photic light-storing material through printing or distributing technique on ceramic biscuit, can present in the dark multiple color, and persistence is long.
Described photic luminescence glass layer, wherein, if by typography, formula by mass percentage, comprises 10 ~ 30% photic light-accumulating powder, 10 ~ 30% high temperature frit, 0 ~ 1% glaze stain and 40 ~ 60% stamp-pad ink; If press distributing technique, formula by mass percentage, comprises 10 ~ 50% photic light-accumulating powder, 60 ~ 80% low temperature frit and 0 ~ 1% glaze stain.
Wherein, described photic light-accumulating powder is rear-earth-doped high temperature long-afterglow material, by rare earth activators doping matrix material, is prepared from, and matrix material is specially Sr

(2) if by typography, take high temperature frit and glaze stain by formula, after mixing with photic light-accumulating powder, cross 80 mesh sieves, add stamp-pad ink, stir; If press distributing technique, by formula, take low temperature frit and glaze stain, after mixing with photic light-accumulating powder, cross 80 mesh sieves;
(3), if by typography, the slip preparing is crossed to the logical reticulated printing of 80 orders on ceramic biscuit; If press distributing technique, mixed frit is crossed to the logical screen cloth material of 80 orders on ceramic biscuit;
(4) in adobe, execute again one deck low temperature frit;
(5) through 850-950 ℃ of kiln, burn till afterwards edging polishing.
beneficial effect
1, photic light-storing material is covered on ceramic body as glass composite bed, the product of making is compared to resinae product on the market, more wear-resisting, chemical resistance, longer service life.
2, adopt ceramic process to produce, technology controlling and process is easy, can be used for producing in enormous quantities.
3, adopt frit serigraphy or distributing technique, can change at any time floral designs, coordinate colorant toning, male and female mold more can present the multiple decorative artistic effect that third dimension is strong, pattern level is abundant.
