Abstract
The invention discloses a preparation method of large-sized ultrathin architectural ceramic tile blanks. The preparation method comprises the following specific steps: firstly weighing kaolin, porcelain stone, potash feldspar, quartz and alpha-Al3O4 micro-powder in proportion; adding weighed substances and water into a ball mill according to a certain proportion, and ball-milling for 25 min to obtain slurry; carrying out semi-dry pressing on the slurry to press into strips; and finally sintering the pressed strips at a certain temperature for 2 h so as to obtain ceramic tile blanks. By introducing lithium-containing porcelain stone with low-temperature melting characteristic to preparation of large-sized ultrathin architectural ceramic tile blanks, firing temperature range of the blanks is greater than or equal to 60 DEG C, firing shrinkage is less than or equal to 6%, and sintering performance of blanks is obviously improved. Meanwhile, by adding the alpha-Al3O4 micro-powder, fracture resistance of ceramic tile blanks is raised to 140 MPa and above. Thus, required processing property and strength requirement for usage of ceramic tile blanks in the preparation process of large-sized ultrathin tiles are effectively satisfied.
Description
Technical field
The invention belongs to building material technical field, the preparation method relating to a kind of super-thin architectural ceramic tile porcelain base.
Background technology
In the stage that architectural pottery reaches its maturity, the research and development of large-scale ultra-thin brick have wide market prospect, compared with Wall or floor tile existing with on market, the large-scale ultra-thin Imitation Rock Porcelain Tiles weight that this specification is 1000 �� 3000 �� 3mm only has the 1/4 of existing Wall or floor tile, it is possible to resolve alleviate a great problem of load in building decoration. Meanwhile, the raw material of use can reduce more than 60%, and the energy uses can also save at least 40%, thus greatly reducing the exploitation to nonmetallic ore, both having protected resource, having saved again production cost. Additionally, because this tile product is thin, soon and uniformly, firing temperature and firing period can reduce, shorten in heat transfer, the harmful substance in flue gas is thus made to decline about 20%��30%. Therefore, the development of Building Ceramics Industry is had very important effect by the research and development of large-scale ultra-thin brick. But, large-scale ultra-thin Imitation Rock Porcelain Tiles, because its area is big, thickness is thin, there is also many technical barriers in processing and use. Wherein, sintering character and porcelain base intensity are one of key technologies during exploitation manufactures.
Summary of the invention
The preparation method that it is an object of the invention to provide a kind of super-thin architectural ceramic tile porcelain base, solves that sintering character in existing super-thin architectural ceramic tile production process is low, the problem of porcelain base intensity difference.
The technical scheme is that, the preparation method of a kind of super-thin architectural ceramic tile porcelain base, specifically implement according to the following steps:
Step 1, weighs following raw material by mass percentage: Kaolin 30%��40%, porcelain stone 40%��45%, potash feldspar 10%��20%, quartz 5%��10%, and above component summation is 100%; Weigh a certain amount of ��-Al3O4Micropowder;
Step 2, the material weighed in step 1 and water are added in ball mill by 1:1 in mass ratio, and spheroidal graphite 25min obtains slurry;
Step 3, adopts semi-dry pressing by slurry, suppresses slivering;
Step 4, sinters 2h at a certain temperature by the bar being pressed into, and namely obtains porcelain base.
Feature of the present invention also resides in,
Wherein porcelain stone is containing lithium porcelain stone.
Wherein ��-Al3O4Micropowder specification is 325 orders, and the amount of weighing is the 20%��30% of raw material total amount.
Wherein in step 2, the ball milling fineness of slurry is 250 mesh screen residue < 0.5%.
Wherein in step 3, sintering temperature is 1200 DEG C��1240 DEG C.
The invention has the beneficial effects as follows, this method introduce in the preparation of super-thin architectural ceramic tile porcelain base have watery fusion characteristic containing lithium porcelain stone, make firing range >=60 DEG C of base substrate, percent of firing shrinkage��6%, hence it is evident that improve the sintering character of base substrate; It is simultaneously introduced ��-Al3O4Micropowder, makes the rupture strength of porcelain base bring up to more than 140MPa, effectively meets processing performance required in large-scale ultra-thin brick preparation process and the requirement of strength of porcelain base use.
