Description
Technical Field
The invention relates to the field of ceramic tiles, in particular to a ceramic tile with high toughness and a preparation method thereof.
Background
Ceramic materials have incomparable advantages with other materials, but the fatal weakness is its brittleness. Because the ceramic material is a polycrystalline structure consisting of ionic bonds or covalent bonds, the ceramic material lacks a slip system which can deform the material, and the inevitable micro defects exist on the surface of the material in the ceramic process manufacturing, namely the ceramic material possibly forms a crack source, so that the rapid propagation and brittle fracture of the crack are caused once external force is applied, and the problem that how to improve the performance and reduce the brittleness of the ceramic is urgently needed to be solved at present;
the vermiculite is a layered silicate mineral, is a natural and harmless mineral, is a clay mineral similar to montmorillonite, is generally yellow, brown and dark green in color, can be changed into grey after being heated, can be used as a building material and the like, has a wide application range, and is not reported in the ceramic industry at present to improve the toughness of the ceramic tile by adopting vermiculite powder.

0.5-1 part of vermiculite, 0.5-1 part of wollastonite, 0.1-0.3 part of adhesive and 0.5-1 part of silicon carbide;
further, the adhesive is a 15% aluminum dihydrogen phosphate aqueous solution.
A preparation method of a ceramic tile with high toughness comprises the following steps:
s1, preparation of vermiculite composition
Preparing raw materials of the vermiculite composition according to parts by weight; mixing vermiculite and wollastonite, crushing and sieving by a 20-50-mesh sieve to obtain a crushed mixture; mixing the crushed mixture with a hydrochloric acid solution, stirring and preserving heat for 2-3h at 70-80 ℃; cooling to room temperature, washing to neutrality, adding adhesive and silicon carbide, and stirring; preserving heat for 4-5h at 90-110 ℃, cooling to room temperature, and drying to obtain a vermiculite composition;
s2. material preparation
Preparing raw materials of the blank body according to the parts by weight, and fully mixing the raw materials to obtain a blank mixture; performing ball milling treatment on the blank mixture by using a ball mill to obtain slurry;

s4, preparing a semi-finished product
And (5) ageing the powder prepared in the step (S3) for 24 hours, pressing, drying in front of a kiln, and finally sintering into a semi-finished blank.
The surfaces of wollastonite and vermiculite can be treated by hydrochloric acid, and then modified by using aluminum dihydrogen phosphate aqueous solution as a binder to ensure that the surfaces of the wollastonite and the vermiculite are uniformly coated with the binder, and then silicon carbide is added; because the laminated structure of vermiculite is formed by combining two layers of laminated silica frameworks and wollastonite or silicon carbide, a double-layer silica tetrahedron is formed, and the structure is favorable for improving the toughness of the green body.
Further, in the step S1, the concentration of hydrochloric acid is 0.8-1.3 mol/L.
Further, in step S2, the ball milling process requires: the water content of the slurry is controlled to be 33-34%, the fineness of the slurry is controlled to be 250-300 meshes, and the fineness and the screen allowance of the slurry are 2-3%.
Further, in the step S4, the firing temperature is 1150-1200 ℃.
The beneficial effects of the invention are:
1. the vermiculite composition is added, so that the toughness of the ceramic tile can be obviously improved, the toughness grade is more than or equal to 3, and the ceramic tile has high toughness;
2. the toughness of the ceramic tile can be measured by the detection method of the impact resistance of the ceramic tile and the falling resistance of different heights, which shows that the ceramic tile prepared by the invention has higher impact resistance recovery coefficient.

The impact recovery coefficient X was determined by randomly selecting commercial tiles according to the evaluation method described in example 5 (10 pieces for 1 height test), and the toughness grade was evaluated according to the evaluation method described in example 5, with the following results in table 2:
TABLE 2
In table 2, we can see:
the test group 1, X =0.93 < 1.0 is more than 0.86, and the toughness grade is 3 grades according to the evaluation method, which shows that the sample to be detected has higher toughness and is not easy to crack; at the moment, when the falling height of the steel ball is 1.0 m, the sample to be detected is intact; the fragmentation rate of the steel ball when the falling height of the steel ball is 1.5 m is 10 percent; the fragmentation rate of the steel ball when the falling height of the steel ball is 1.8 m is 20 percent; the requirements of the fracture rate of the falling resistance test recorded in the table 1 are met, and the toughness of a sample to be tested can be evaluated;
the test group 2, 1.2 < X =1.3, the toughness grade is 5 according to the evaluation method, which shows that the sample to be detected has very high toughness and is difficult to crack; at the moment, when the falling height of the steel ball is 1m, the sample to be detected is intact; when the falling height of the steel ball is 1.5 m, the sample to be detected is intact; when the falling height of the steel ball is 1.8 m, the sample to be detected is intact; when the falling height of the steel ball is 2.0 m, the sample to be detected is intact; the requirements of the fracture rate of the falling resistance test recorded in the table 1 are met, and the toughness of a sample to be tested can be evaluated;
the test group 3, 0.55 > X =0.4, the toughness grade is 0 grade according to the evaluation method, which indicates that the sample to be detected has very low toughness and is very fragile; at the moment, the fragmentation rate of the steel ball when the falling height of the steel ball is 1m is 70 percent; the requirements of the fracture rate of the falling resistance test recorded in the table 1 are met, and the toughness of a sample to be tested can be evaluated;

therefore, it can be seen that the toughness of the tile can be measured by the magnitude of the impact recovery coefficient and the falling resistance, and the larger the impact recovery coefficient is, the better the falling resistance is, the better the toughness of the tile is, otherwise the worse the toughness is. If the impact resistance recovery coefficient of the ceramic tile is less than 0.55, the toughness of the ceramic tile is poor, and if the impact resistance recovery coefficient is more than 0.90, the toughness of the ceramic tile is good;
meanwhile, the anti-falling result is also within the fragmentation range in the evaluation method, which shows that the toughness evaluation method of the invention has certain applicability, can directly compare with the K value through the measured impact resistance recovery coefficient X, and then evaluates the toughness of the ceramic tile according to the toughness grade evaluation method, so as to evaluate the toughness grade of the ceramic tile and conveniently screen ceramic tile products with high toughness and poor toughness.
