In described coloured decorative devitrified glass layer or the wired linear marking of surface arrangement.
Embodiment
Below by embodiment, further illustrate technical scheme of the present invention.
Its coloured frit of embodiments of the invention all adopts the coloured frit of commercially available Dow company.
Embodiment 1
As shown in Figure 1, it from bottom to top comprises end base layer 1 and coloured decorative devitrified glass layer 2 to a kind of glass-ceramic clad plate successively, the wired linear marking 3 of surface arrangement of described coloured decorative devitrified glass layer 2.
Specification as above is the glass-ceramic clad plate manufacture method of 1000*1000mm, and step comprises successively:
A, ceramic powder compacting is formed to adobe the dry end base layer 1 that forms;
B, (wherein 20-30 order accounts for 5% first by a kind of fineness of screen printing, to be distributed as 20-100 order, 30-100 order accounts for 95%), initial melting temperature is that thin coloured frit 1.5kg of 1050 ℃ forms thin coloured microcrystalline coating 21, by hollow out roller, print a kind of fineness again and be distributed as 30-100 order, initial melting temperature is that thin coloured frit 0.5kg of 1060 ℃ forms thin coloured microcrystalline coating 22;
C, by fineness 4-20 order, (wherein 20-30 order accounts for 5% for thick coloured frit of initial melting temperature 1080 and fineness 4-30 order, 4-20 order accounts for 95%) thick coloured frit of 1100 ℃ of initial melting temperatures forms thick coloured microcrystalline coating 23 after mixing the adobe of rear cloth 4kg after step C
D, use that 3 diameters are respectively 5,8, the pipe of 10mm drenches fineness 250 mesh screen residues 2%, the frit slurry of proportion 1.5 forms linear and decorates texture 3, and the frit initial melting temperature of preparation frit slurry is 1050 ℃, and consumption is 0.5kg;
The PVA solution of E, spray content 0.01% is fixed, and burns till, polishing packing warehouse-in.
The glass-ceramic clad plate of the present embodiment after firing, its decorative devitrified glass layer 2 is merged and forms mutually by thin coloured microcrystalline coating 21, thin coloured microcrystalline coating 22, thick coloured microcrystalline coating 23, and linear is decorated the surface that texture is positioned at decorative devitrified glass layer 2.Step B forms decorative pattern after printing thin coloured frit, first melting in the process of firing, the thick coloured frit layer forming because being suppressed with step C cloth on thin coloured frit, thereby can be filled in the particle gap of thick coloured frit layer after thin coloured frit layer melting, multi-layer intercrossed decorative effect formed.
Should be noted that and adopting in coloured frit situation of same recipe, because thin coloured frit granularity is little, specific surface area is large, and surface can be large, thereby melt temperature is low; When adopting coloured frit of different ingredients, the height that can change melt temperature by the adjusting of formula is to meet the needs of technique.
The present embodiment is used frit slurry to replace frit powder to form linear texture, can drench the pouring slurry speed of slurry pipe and thickness and the trend that direction is controlled lines by adjusting, and by the number that pipe is starched in pouring, control the number of lines, product lines sharpness of border after firing, remarkable fluency, the ice crack producing just as lithotome, crystal stereo natural, is the favorable substitutes of lithotome.
