Specifically, the powder is pressed and formed under the unit pressure of 310-340bar, so that the green strength is good, and the drying and the firing are easy.
The traditional granite blank formula mainly uses raw slime to provide plasticity, meanwhile, a large amount of pigment is often required to be added into a dark blank, and the content of the pigment can reach more than 2% in many cases, so that the blank is easy to have the problem of black core caused by insufficient oxidation during firing, and the pigment cost is very high. The raw ore mud with the C content lower than 0.5 percent is selected in the blank formula, the using amount is controlled within 5 percent, a large amount of water washed sand with the C content lower than or equal to 0.2 percent and raw ore bentonite are used to adjust the blank plasticity, the vanadium-titanium slag is used to replace pigments for color development, the blank prepared by the low C content is easy to oxidize and burn and is not easy to generate black cores, the capacity can be improved by 15 to 30 percent compared with the traditional formula, and simultaneously, the vanadium-titanium slag can completely replace black pigments in gray-black blanks, thereby greatly reducing the cost of the pigments for the blank.
The following description will be given by way of a specific example.
Referring to fig. 4, the preparation method of the dark granite ceramic tile specifically comprises the following steps:
s1, blending raw ore clay 3-5%, washed sand 13-16%, raw ore bentonite 4-5.5%, medium-high temperature potassium sand 35-40%, medium-low temperature sand 15-20%, recycled waste 10-15%, flux raw material 4-5%, vanadium-titanium slag 4-6%, sodium silicate 0.8-1.0%, sodium naphthalene sulfonate 0.05-0.1% and reinforcing agent 0.1-0.2% to obtain dry material;
step S2, adding water according to the ratio of the dry materials to the water of 1: 0.5;
step S3, loading the dry material added with water into a ball mill, and grinding for 10-11 hours to obtain semi-finished slurry;
step S4, sieving the semi-finished product slurry through a 70-mesh sieve to obtain slurry;
s5, performing spray drying treatment on the slurry by using a spray drying tower to obtain powder with the water content of 7.0-7.5%, the particle size of more than 40 meshes of 45-50% and the powder volume weight of more than 0.92 g/mL;
step S6, ageing the powder for more than 24 hours;
and S7, pressing and forming the aged powder under the unit pressure of 310-340bar to obtain a dark-color granite ceramic tile green body, and treating the dark-color granite ceramic tile green body to obtain the dark-color granite ceramic tile.
The invention also provides a dark granite ceramic tile which is prepared by the preparation method of the dark granite ceramic tile.
In summary, the preparation method of the dark granite ceramic tile and the dark granite ceramic tile disclosed by the invention comprise the following steps: proportioning raw materials for a preset blank according to a raw material formula, and then preprocessing the mixture to obtain slurry, wherein the raw material formula for the preset blank contains vanadium-titanium slag; drying the slurry to prepare powder to obtain powder; and carrying out compression molding treatment on the powder to obtain a dark-color granite ceramic tile green body, and treating the dark-color granite ceramic tile green body to obtain the dark-color granite ceramic tile. According to the invention, the industrial tailings vanadium-titanium slag is used to replace a black pigment to develop color, the consumption of traditional clay raw ore mud (the content of C is generally more than 0.5%) which is difficult to burn through and easy to blacken but has good plasticity in the blank is greatly reduced, the plasticity of the blank is adjusted by using a part of washed sand (the content of C is less than or equal to 0.2%) raw materials which have the advantage of low carbon content but have plasticity inferior to that of the raw ore mud and the raw ore bentonite, the prepared blank is suitable for quick firing and has good drying strength, the consumption of the pigment can be greatly reduced, the cost of the pigment for the blank is greatly reduced, and the capacity of the green body of the dark-color granite ceramic tile is improved.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
