Description
Technical Field
The invention relates to the field of ceramic materials, in particular to a multi-element composite flux low-temperature sintered marble tile blank and a preparation method thereof.
Background
The ceramic belongs to the high-energy-consumption industry, taking ceramic bricks as an example, the traditional production technology has the defects of high firing temperature, long firing period, high energy consumption and cost and low yield, and the development of the industry is seriously hindered. At present, the energy utilization rate of the ceramic industry in China is far from the abroad. The energy utilization rate of developed countries is generally up to more than 50%, the energy utilization rate of the developed countries reaches 57% in the United states, and the energy utilization rate of the developed countries only reaches 28% -30%, so that the energy consumption is reduced, and the energy utilization rate is increased. In order to solve or alleviate the situation, the low-temperature fast burning technology is developed. Aiming at the ceramic industry, the low-temperature quick firing technology is a firing process which obviously shortens the firing time and ensures that the product performance is the same as or similar to that of the product produced by adopting the traditional technology; according to thermodynamic equilibrium calculation, the firing temperature is reduced by 100 ℃, and the heat consumption of a unit product can be reduced by more than 10%; the sintering time is shortened by 10%, the yield can be increased by 10%, and the heat consumption is reduced by 4%. Therefore, the low-temperature fast firing technology can remarkably reduce the unit energy consumption and cost of enterprises while increasing the yield of the ceramic product, and realize energy conservation and emission reduction, thereby providing a way for realizing sustainable development for the development of the ceramic industry.
In general, the addition of a fluxing agent to the body increases lattice defects, lowers the temperature at which the body will exhibit a liquid phase, and promotes the formation of mullite in the body. A common fluxing agent is alkali metal oxide (Li)2O、Na2O and K2O) and alkaline earth metal oxides (CaO and MgO). The lithium has low atomic weight and high surface charge density of lithium ions, so that the lithium ions have high electrostatic field, therefore, the lithium ions have high electrostatic charge density2O has very strong fluxing effect, can obviously reduce the sintering and melting temperature of the material, can reduce the thermal expansion coefficient of the melt, and can shorten the sintering time. The patent CN201210446388.9 utilizes the lithium feldspar in the lithium mine tailings as a green brick cooling material, overcomes the defects of high firing temperature and long firing time of the glazed brick in the prior art, and realizes low-temperature quick firing of the glazed brick. However, Li2Small surface tension of O melt and high yieldThe raw capillary force is also small, which is not beneficial to tensioning the blank particles and carrying out the vitrification reaction, so that the comprehensive performance of the fired blank is poor, the breaking strength of the fused mass is reduced along with the increase of the content of the lithium oxide, the melting temperature range is narrowed, and the thermal expansion coefficient is increased. In the patent CN1275547A, 10-30% of albite or 1-4% of alkaline earth metal mineral is introduced into the blank, the blank is sintered at 1230 ℃ for 120min, the physical properties of the sintered product meet the national standard of daily fine porcelain, but the fluxing and cooling effects of the independent albite or alkaline earth metal mineral are not obvious, the sintering temperature is still higher, and the sintering period is longer.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a multi-element composite flux low-temperature sintered marble tile blank and a preparation method thereof.
In order to achieve the purpose, the invention adopts the technical scheme that: a multi-element composite flux low-temperature fired marble tile blank comprises the following components in percentage by weight: SiO 2264～69％、Al2O318～20％、Fe2O30.4～0.6％、TiO20.15～0.2％、CaO 0.4～2.0％、MgO 1.4～2.2％、K23.5 to 4.5 percent of O and Na2O 2.0～3.5％。

The water absorption rate mainly represents the degree of cooking, the strength of the cooked blank represents the workability of the ceramic tile, the shrinkage rate represents the shrinkage of the ceramic tile in the firing process, the water absorption rate is less than 0.5 percent, and the strength of the cooked blank is more than or equal to 35MPa, which indicates that the properties of the blank after firing meet the national standard of the ceramic tile (GB-T4100-2015). As is apparent from Table 3, the green compacts obtained in examples 1 to 5 were fired for a short time, and the fired products had high strength and low water absorption and shrinkage. Meanwhile, the dolomite, diopside and albite are zero at most in the examples 6-9, otherwise the blank is difficult to burn, the sum of the three components is not less than 1.5, otherwise the blank is not easy to burn (example 8) and not more than 8 parts, otherwise the blank is easy to burn too much (example 9). The examples 1 to 5 show that the eutectic effect of the calcium-magnesium ion flux is far more obvious than that of potassium-sodium, so the content of the calcium-magnesium ion flux is in a proper range and is not too high or too low.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
