Description

A kind of green body and preparation method thereof enhancing Imitation Rock Porcelain Tiles paving adhesion strength
Technical field
The invention belongs to architectural pottery fields, and in particular to a kind of green body and its system for enhancing Imitation Rock Porcelain Tiles paving adhesion strength Preparation Method.
Background technique
Hollowing phenomenon is always the Imitation Rock Porcelain Tiles quality problems common in paving and use process, potential safety caused by it Hidden danger greatly limits the use scope of Imitation Rock Porcelain Tiles.On the one hand, tilting or falling off easily occur in use in hollowing Ceramic Tiles, shadow Ring decorative effect；On the other hand, when hollowing phenomenon occurs easily to form product at hollowing in the Water Districts domain such as balcony, kitchen, bathroom Water generates stench, seriously affects people and occupies experience.Bond strength deficiency between binder based on Ceramic Tiles and cement mortar is One of the reason of causing hollowing.It solving to increase in Ceramic Tiles and the intensity of binder, glue for tile is a kind of mode being often used, But its cost is often several times of ordinary mortar, and construction cost is higher.Chinese invention patent CN107129308A discloses one kind The Ceramic Tiles adobe and its preparation method and application that anti-hollowing falls off will contain pore creating material in situ by the way of layer-by-layer distribution Powder cloth impose on bottom, so that bottom is formed biggish pore structure, pass through increase ceramic tile and binder contact area and pinning The generation of effect reduction hollowing phenomenon.But by Ceramic Tiles and binder bond strength the study found that water absorption rate is to influence The very important factor of adhesion strength.The water absorption rate for controlling Ceramic Tiles to a certain extent, can effectively reduce Ceramic Tiles hollowing Risk, therefore, can be improved bottom green body water absorption rate enhancing Imitation Rock Porcelain Tiles paving adhesion strength.But for Imitation Rock Porcelain Tiles, national standard rule Determine the water absorption rate and intensity of full sized brick, therefore wants the water absorption rate of suitable control bottom, thickness.Meanwhile the base of different material property It is easily deformed in body sintering cooling and storage process, therefore, to consider the composition matching of bottom blank and surface layer blank.
Summary of the invention
It is an object of the invention in view of the above shortcomings of the prior art, provide a kind of enhancing Imitation Rock Porcelain Tiles paving adhesion strength Green body and preparation method thereof.
The technical solution adopted by the present invention is that：A kind of green body enhancing Imitation Rock Porcelain Tiles paving adhesion strength, which is characterized in that The green body is followed successively by surface layer and bottom from top to bottom, and wherein bottom is that open structure Shi matter layer or ceramic layer, water absorption rate are lower than 0.5%；The water absorption rate of the bottom is higher than 0.5%, and surface layer and the drying shrinkage difference of bottom is less than 0.2%, surface layer and Less than 0.2%, the chemical component and mass percent of the bottom are the percent of firing shrinkage difference of bottom：
Further, raw material used in the bottom and its by mass percentage proportion be：
Further, the chemical component of the surface layer and mass percent are：
Further, raw material used in the surface layer and its by mass percentage proportion be：
Further, the water absorption rate of the surface layer is lower than 0.5%, and surface layer water absorption rate is conducive to improve full sized brick less than 0.5% Waterproof performance.
Further, the surface layer and the drying shrinkage difference of bottom are less than 0.2%；Surface layer and the dry of bottom are shunk The difference of rate can make surface layer and bottom in the drying process, contraction is consistent, so that full sized brick is in drying less than 0.2% Shape is unlikely to deform in the process.
Further, the surface layer and the percent of firing shrinkage difference of bottom receive the firing of surface layer and bottom less than 0.2% Shrinkage difference is conducive to surface layer and bottom and shrinks in sintering process be consistent, so that full sized brick is in drying process less than 0.2% Middle shape is unlikely to deform.
A kind of preparation method for the green body enhancing Imitation Rock Porcelain Tiles paving adhesion strength, includes the following steps：
(1) according to raw material proportioning, the raw material of surface layer or bottom is weighed respectively, is added suitable water, after respective ball milling, sieving Except iron, surface layer slurry and base pastes are respectively obtained；
(2) respectively by the surface layer slurry of step (1) and base pastes it is aging after mist projection granulating, respectively obtain surface layer powder and Bottom powder；
(3) by the surface layer powder and bottom powder of step (2), by the mode secondary material distributing just beaten, and green body bottom is controlled The thickness of layer, it is dry-pressing formed to obtain the green body containing double-layer structure；
(4) green body of step (3) is dry in dry kiln；
(5) by green body dried in step (4), through dry before leaching ground coat enamel, ink-jet printed, leaching throwing glaze, kiln, into firing Kiln firing, obtains the semi-finished product of Ceramic Tiles；
(6) polished, edging, waxing by the semi-finished product of step (5), obtain final products.
Further, the moisture content 60%~65% of surface layer slurry and base pastes in the step (1), Ball-milling Time are 6~8 hours, it was 0.8%~1.0% that surface layer slurry and base pastes, which cross 250 mesh screen residues, and flow rate of slurry is 30~70 seconds.
Further, in the step (2), surface layer slurry and base pastes aging time are 6~12 hours, surface layer powder And the moisture content of bottom powder is 7%~9%, and surface layer powder and bottom powder are sieved with 100 mesh sieve down and tailed over less than 5%, surface layer It is 30~50% that powder and bottom powder, which are crossed on 40 mesh and tailed over, and surface layer powder and bottom powder are crossed on 20 mesh and tailed over less than 1%.
Further, the thickness of control green body bottom accounts for the 10%~20% of entire adobe thickness in the step (3)；It is logical The thickness for crossing control green body bottom, so that relatively thin bottom is smaller to the intensity effect of full sized brick.
Further, drying temperature is 160~180 DEG C in the step (4), and drying time is 40~60 minutes.
Further, in the step (5), the face temperature maximum temperature of calcining system is 1180~1210 DEG C, and bottom temperature is most High temperature range is 1210~1230 DEG C, and firing time is 55~65 minutes.
Beneficial effects of the present invention are：Green body is double-layer structure in the present invention, is followed successively by surface layer and bottom from top to bottom, and Optimize bottom chemical component proportion, so that bottom forms the Shi matter layer or ceramic layer of open structure, and makes the water absorption rate of bottom Higher than 0.5%, the water absorption rate of green body bottom is improved, to enhance the adhesion strength of Ceramic Tiles and cement mortar, effectively The hollowing for reducing Ceramic Tiles falls off risk；Double-layer structure Imitation Rock Porcelain Tiles prepared by the present invention can cooperate with conventional cement mortar and make With compared with the methods of glue for tile paving, cost is lower.
Compared with existing bottom is using pore creating material technology, the present invention has preparation method simple, does not need additional pore former, The bottom side for also avoiding preparing by pore creating material simultaneously easily exposes porous structure, influences the beauty of full sized brick.
