Description

A kind of wall floor tile and manufacture method thereof
Technical field
The present invention relates to a kind of ceramic, relate in particular to a kind of wall floor tile and manufacture method thereof.
Background technology
Existing wall floor tile is raw materials such as feldspar, pottery stone, porcelain stone, porcelain sand, potter's clay, china clay, talcum, zircon sand, quartz and clay class mineral plastic materials such as (as kaolinite class mineral, smectite type mineral (as wilkinite), illite class mineral) are mixed according to a certain percentage and levigate, powder process, shaping, drying, to burn till.Its common base substrate chemical ingredients is: SiO 263~75%, Al 2O 315~23%, CaO+MgO=0~3%, K 2O+Na 2O+Li 2O=4.0~10%, Fe 2O 3+ TiO 2=0~3%, ZrO 2=0~10%.Existing wall floor tile exists following defective: one, owing to Al in its chemical ingredients 2O 3Higher, formed glassy phase crystallization ability is stronger in the base substrate sintering process, and it is relatively poor that base substrate burns till the back light transmission, thereby poor, the beautiful texture of wall floor tile light transmission that makes is relatively poor, exterior decorative effect is undesirable.Two, because Al 2O 3The content height, in the base substrate sintering process higher, the diffusibility of formed glassy phase viscosity a little less than, the glassy phase of viscosity higher is difficult to infiltrate and be filled in the hole of base substrate inside, still have higher water-intake rate after base substrate burns till, thereby the didirtresistance of base substrate is relatively poor.Three, for common wall floor tile, because common selected raw material Fe 2O 3+ TiO 2Content is higher, and the base substrate whiteness is not high.Therefore, for improving the base substrate whiteness and reducing Al 2O 3Content, prior art generally, the one, introduce a certain amount of quartz, but quartzy add-on can not too high (generally less than 35%), otherwise the volumetric expansion that brings owing to quartzy moment crystal conversion when burning till, be easy to make the very big stress of the inner generation of base substrate, cause the cracking and the distortion of base substrate.The 2nd, in base substrate, introduce the zircon sand (powder) of a certain amount of (2~10%), but because zircon sand (powder) has radioactivity, thereby prepared wall floor tile also has radioactivity.Simultaneously because the introducing of zircon sand (powder) has also reduced the light transmission of wall floor tile, beautiful texture.
Summary of the invention
The object of the present invention is to provide that a kind of whiteness height, good, the beautiful texture of light transmission are strong, "dead", didirtresistance and exterior decorative effect be good, the wall floor tile of the not easy to crack and distortion of base substrate, and the manufacture method of this wall floor tile.
Purpose of the present invention is achieved by the following technical programs:
A kind of wall floor tile provided by the invention, its raw material consists of quartzy 65-90%, flux 5-30% and clay class mineral 5-30% by weight percentage; Described flux is the one or more combination of the fluorochemical of the muriate of oxide compound, metal of carbonate, vitriol, nitrate, phosphoric acid, phosphoric acid salt, boric acid, borate, silicate, silicofluoride, metal or metal.Preferred version is: its raw material consists of by weight percentage: quartzy 70-82%, flux 8-11% and clay class mineral 9-22%.
Wall floor tile of the present invention is to be main raw material with the quartz, described flux is used for before base substrate burns till and quartzy mixed calcining, the stress that brings to base substrate to eliminate or to weaken volumetric expansion that crystal conversion quartzy in the sintering process produces, so can introduce a large amount of quartz in the base substrate.Generally coloring element content is lower in the quartz, so the increase of quartz content can make the whiteness of base substrate be significantly improved in the base substrate.In addition, because the increase of quartz content, formed glassy phase crystallization ability weakens in the base substrate sintering process, becomes glass power to strengthen, and the light transmission of base substrate and beautiful texture are obviously strengthened, and decorative effect is able to obvious improvement.In addition, because Al in the selected raw material of wall floor tile of the present invention 2O 3Content is lower, thereby can reduce formed glassy phase viscosity in the base substrate sintering process, and can improve its diffusibility.More low viscous glassy phase more easily infiltrates and is filled in the hole of base substrate inside, reduced base substrate and burnt the back water-intake rate, thereby the didirtresistance of base substrate is better.Simultaneously, owing to Al in its chemical constitution 2O 3Lower, in the base substrate sintering process formed glassy phase crystallization ability a little less than, it is better that base substrate burns till the back light transmission, thereby good, the beautiful texture of wall floor tile light transmission that makes is strong, exterior decorative effect is better.
Preferred flux of the present invention component by weight percentage is yellow soda ash 16%~47%, Sodium Silicofluoride 16~47%, lime carbonate 23~53%, talcum powder 7~25%, barium carbonate 7~19%.Perhaps preferred flux is yellow soda ash.

(3) the base substrate mixture is made the wall floor tile according to ordinary method.
Quartzy mixes with flux and through calcining, metal ion, fluorion, chlorion contacts with quartzy in the flux, under the high temperature with quartz in silicon ion fight for oxygen, siloxane bond is ruptured, formation silicate or silicate glass.Therefore destroy quartzy crystalline structure, eliminated or reduced the volumetric expansion of quartzy crystal conversion generation.Generally, if quartz does not mix with flux and through calcining, and directly join in the base substrate of wall floor tile, after base substrate burns till, be easy to the volumetric expansion that crystal conversion produced because of quartz and cause the sintered compact cracking or crack.The purpose that adds plastic materials such as clay class mineral such as kaolinite class mineral, smectite type mineral (as wilkinite), illite class mineral is in order to improve the forming property of base substrate, to increase the associativity of base substrate and the green strength that improves base substrate.If do not add or add less plastic raw materials such as clay class mineral in the base substrate, base substrate will be difficult to be shaped (especially dry powder press forming).
In the wall body brick preparation method's of the present invention step (3), can be undertaken by following measure: the base substrate mixture is levigate and make moisture 4.5%~12.0% powder, the fineness of powder is that 10000-hole sieve tails over 0~4%, after this powder pressing forming and drying, put into kiln and fire under 1150 ℃~1350 ℃, the firing time is 0.3~12 hour.
In order to improve the decorative effect of brick body, also can after compression moulding of base substrate mixture and drying, contain the paste or the soluble powder of soluble salt solution at its surface printing earlier, and spray water or penetration-assisting agent, and then put into kiln and fire, polish after burning till.
