Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to specific embodiments.
The invention provides repair mud for a sanitary ceramic semi-finished product, which comprises the following components in percentage by mass: 52-72% of production slurry, 8-20% of quartz, 2-4% of calcined kaolin, 0.5-2.5% of dolomite, 7-13% of porcelain powder and 6-15% of rock wool.
Preferably, the repair mud comprises the following components in percentage by mass: 55-70% of production slurry, 10-20% of quartz, 2.5-4% of calcined kaolin, 0.5-2% of dolomite, 8-12% of porcelain powder and 8-12% of rock wool.
More preferably, the repair mud comprises the following components in percentage by mass: 60-68% of production slurry, 10-15% of quartz, 2.5-3% of calcined kaolin, 0.5-1.2% of dolomite, 8-10% of porcelain powder and 8-10% of rock wool.
The production slurry is the slurry used for grouting sanitary ceramics, and can be selected by a formula well known by a person skilled in the art. For example, the components of the production slurry can refer to CN102942384A, paragraph 0015 of the specification of the repair slurry for sanitary ceramics, but are not limited thereto.
The quartz can stabilize the sintering temperature of the repair mud, and when the addition of the quartz is more than 20 wt%, the sintering temperature of repair can be influenced, so that the width of repaired cracks is reduced, and even the cracking phenomenon can occur; when the addition amount of quartz is less than 8 wt%, the product repair mud is easy to over-burn, and a good repair effect cannot be achieved.
The calcined kaolin has a stable structure, a small thermal expansion coefficient and small volume change in high-temperature exothermic reaction, can reduce stress in firing, can reduce cracking defects and can reduce high-temperature deformation defects.
Dolomite is a good high-temperature fluxing raw material, can reduce the firing temperature of clay and promote the melting of quartz. When the addition amount of dolomite is more than 2.5 wt%, the crack of the repair mud is easily caused; when the addition amount of dolomite is less than 0.5 wt%, the melting temperature of the repair mud is too high, the repair mud is difficult to burn, and the repair effect is poor.
The main chemical components of the porcelain powder are silicon oxide and aluminum oxide, the compositions of the porcelain powder are similar to those of a blank body and are compatible, and the fusion of the repair mud and the blank body is effectively improved.
Specifically, the average particle size of the rock wool is 0.2-1.6 mm. Illustratively, the rock wool has an average particle size of 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4 mm. Furthermore, the particle size of rock wool is 0.25-1.5 mm.
The rock wool is made up by using basalt and dolomite as main raw materials, and adopting high-speed centrifugal equipment after high-temp. melting process. In the prior art, only fine cracks can be repaired by adding glass fiber or refractory cotton and the like, and the rock wool with the average particle size of 0.2-1.6 mm is adopted, so that the toughness of the repair mud can be further improved, and the width of the repair cracks of the repair mud can be effectively improved. When the average particle size of the rock wool is less than 0.2mm, the repaired part is easy to crack, and the repairing effect is poor; when the average particle size of rock wool is larger than 1.6mm, white spots appear on the repaired part after firing, and the expected repairing effect cannot be achieved.
The repair mud for the sanitary ceramic semi-finished product also comprises 0.65-3.5 wt% of pigment. Specifically, the pigment comprises 0.5-1.5 wt% of yellow pigment, 0.1-1 wt% of red pigment and 0.05-1 wt% of black pigment. According to the invention, the color of the repaired part can be consistent with that of the blank body by adding the coloring material.
The invention also provides a preparation method of the repair mud for the sanitary ceramic semi-finished product, which comprises the following steps:
s1, uniformly mixing the production slurry, quartz, calcined kaolin, dolomite, porcelain powder and rock wool according to the proportion to obtain base slurry;
specifically, step S1 includes:
s11, uniformly mixing the production slurry, quartz, calcined kaolin, dolomite and porcelain powder according to the proportion to obtain a mixture;
s12, ball-milling rock wool and then sieving, and taking materials on a screen;
and S13, adding the materials on the screen into the mixture, and uniformly mixing to obtain the basic slurry. The mesh number of the screen in the step S12 is 10-80 meshes. The rock wool: ball grinding: 1 in water: (5-7): (11-13). Further, rock wool: ball grinding: water 1: 6: 12.
s2, drying the basic slurry until the water content is 15-25 wt%, and obtaining the repairing mud for the sanitary ceramic semi-finished product.
Specifically, step S2 includes:
s21, adding the pigment into the basic slurry, and uniformly mixing to obtain color slurry;
s22, drying the color paste until the water content is 15-25 wt%, and obtaining the repairing mud for the sanitary ceramic semi-finished product.
The preparation method of the repair mud for the sanitary ceramic semi-finished product has the advantages of simple process and strong practicability, and can improve the performance of the product and reduce the cost.
The invention also provides application of the repair mud for the sanitary ceramic semi-finished product in the field of repairing the sanitary ceramic semi-finished product. Which comprises the following steps:
(1) repairing the part needing to be repaired on the sanitary ceramic semi-finished product by using the repairing mud;
(2) glazing and firing the repaired sanitary ceramic semi-finished product.
The invention is further illustrated by the following specific examples.
