Polishing glass facing brick and manufacture method thereof
Technical field
The present invention relates to a kind of polishing glass facing brick product and manufacturing process thereof.
Background technology
CN00130117.9 discloses a kind of " glass-ceramics composite board and production method thereof ", its purpose provides a kind of glass-ceramics composite board and production method thereof, the glass ceramics frit that it utilizes common process to produce, with this devitrified glass coefficient of expansion basically identical and through this glass ceramics frit of carrying that evenly distributes on the ceramic substrate of biscuiting, be positioned over to fire in the kiln and form.Its another purpose is to provide a kind of glass-ceramics composite board with the aforementioned production method preparation.Its technology constitutes: described glass-ceramics composite board is composited by top glass-ceramic layer and following ceramic substrate tight bond.The production method of described manufacturing glass-ceramics composite board comprises the following steps: that (one) prepares a kind of glass ceramics frit, its composition range following (percentage by weight): SiO
258~65%; Al
2O
34~8%; KNaO 0~4%; CaO 0~25%; MgO 0~2%; BaO 0~2%; ZnO 4~9% and an amount of fining agent and colorant, the glass frit preparation of this scope, carry out through the following steps: (1) evenly disposes batch by the mentioned component scope; (2) under 1400~1580 ℃ of temperature ranges, found into glass metal; (3) the glass metal water-cooled becomes the mm glass ceramics frit grain of 1~8 scope, then oven dry or air dry; (2) preparation ceramic substrate, its composition range is (percentage by weight): SiO
260~70%; Al
2O
3L 3~20%; KNaO 3~8%; CaO 2~6%; MgO 0~2%; Fe
2O
30~2%; Its mineral composition scope is weathered feldspar, quartz, clay, limestone, calcite, calcium carbonate, wollastonite; Carry out through the following step: (1) above-mentioned each mineral batching, evenly be mixed with batch by the composition scope, through wet ball grinding, spray drying granulation, the slurry fineness is that square hole tails over 1~10%; (2) powder moisture content is 5~8%, and the powder particle is to be to be 50~90% on<1%, 60 mesh sieves on 20 mesh sieves; (3) powder is shaped through the automatic brick machine of pottery, and specification limit is 200 * 200mm to 1000 * 1000mm; (4) biscuiting in 600~1200 ℃ of temperature ranges. (three) are uniformly distributed in the glass ceramics frit grain on the ceramic substrate of biscuiting, this frit grain thickness is 2~8mm, spray an amount of fixative, be positioned in the ceramic roller kiln and burn till, firing temperature is 1140~1250 ℃, firing period is 1~3.5 hour, and cooled semiproduct become finished product after cutting edge, polish, check, packing.Its weak point is: the ceramic substrate of compression moulding will be sintered into biscuit in advance, on the biscuit glass ceramics frit grain is being uniformly distributed on the substrate then, carries out burning till the second time in roller kilns making it to become composite plate; Its weak point also is: the glass frit particle surface layer and the edge of dried cloth is uneven on the biscuit, will carry out processing such as a large amount of side cuts, strickling, grinding and polishing to the surface of composite plate behind the kiln discharge; Cutting output is big, and waste of raw materials is big, the energy consumption height.
CN00136831.1 discloses " a kind of preparation method of devitrified glass one ceramic compounded decorative plate ", its purpose provides a kind of preparation method of devitrified glass one ceramic compounded decorative plate, with the process equipment of producing the traditional ceramics floor, but require to add the glass slag body of the crystallization of different styles or tone according to pattern on the ceramic body surface, utilize the stove of sintered ceramic, preparation devitrified glass one ceramic compounded decorative plate.Its technology constitutes: the preparation method of described devitrified glass one ceramic compounded decorative plate may further comprise the steps: (1) cloth: the general floorings ceramic powder is injected mould to 3/5~4/5 of required gross thickness; With ceramic powder with carry out the cloth second time after but the glass slag charge of one or more crystallization mixes in the ratio of 1:0.05~0.6, reach till the required gross thickness; (2) under the pressure of 20~40MPa, mould is forced into the blank forming desired density: (3) oven dry: base substrate is dried between 150~300 ℃; (4) sintering: utilize roller kilns Fast Sintering ceramic body, simultaneously, glass slag crystallization.Cooling is immediately come out of the stove; (5) corase grind polishing: after the ceramic idiosome that will come out of the stove was thrown through edging, essence, devitrified glass showed distinctive color and light.Foregoing invention is that ceramic powder and the glass slag charge that will prepare divide secondary material distributing, extrusion forming; Its weak point is: the ceramic powder bed of material and the compression of the glassy layer founded in advance be than different, wants to be covered with the surface and do not leak end base after polishing, and just needs a large amount of top layer ceramic powders and the compound of glass slag charge, the big cost height of top layer compound consumption; The glass slag charge contacts with the glued membrane of mould when compression moulding simultaneously, and mould damages easily; Need strickling, grinding and polishing after burning till equally, its cutting output is big, and waste of raw materials is big, the energy consumption height.
The weak point of above-mentioned two inventions also is the variation of the decorative pattern that it is surperficial, only is the collocation of different colours glass particle material or extremely simple decorative pattern, and whole surface color or color pattern are single.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point of the prior art, a kind of intensity of pottery and polishing glass facing brick of decorate properties such as the stereo transparent of abrasion resistance and glass and brightness of integrating is provided.Another object of the present invention provides a kind of manufacture method that glass and ceramic process are combined.
