Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building materials, and particularly relates to a high-strength corrosion-resistant ecological ceramic plate and a preparation process thereof. BACKGROUND

[0002] The ceramic plate is a new type of curtain wall material in the current building industry, and has the advantages of environmental protection, energy saving, moisture resistance, air permeability, sound insulation, rich and long-lasting color, wide application range and the like. It combines traditional materials with modern buildings, and provides a more flexible external facade design solution for design and application, and is conducive to beautifying the city and building a livable environment. At present, the material on the market uses pure natural clay as a raw material, adds a small amount of quartz, pumice, feldspar and other ingredients such as colorants, and is formed by high-pressure extrusion, low-temperature drying and high-temperature firing at 1200-1250 DEG C, and has the characteristics of green environmental protection, no radiation, soft color, and no light pollution.

[0003] The rise of the ceramic plate brings a large demand for natural clay, but the clay resource is limited, and the exploitation of clay will inevitably cause damage to nature, so the technical field begins to explore the use of silt, waste ceramic or iron ore tailings as the raw material of the ceramic plate. For example, CN1027958381A discloses a low-temperature fast-fired environment-friendly ceramic plate prepared from iron ore tailings and a preparation method thereof, and CN103896556A discloses a new environment-friendly energy-saving curtain wall material made of silt and waste ceramic. However, the preparation process of the ceramic plate in the above two technical solutions adopts one-step firing method, and it is found through practical application that the finished product has high brittleness and low corrosion resistance. The strength of the ceramic plate is higher than that of natural stone, but it is also a brittle material like natural stone, and has weak impact resistance. The ordinary installation method of the ceramic plate theoretically meets the technical requirements, but due to the discreteness in the production and installation process and other uncontrollable factors, there is a possibility of accidental fracture, fragmentation (such as hard object collision when cleaning the curtain wall) and falling during use. Moreover, the ceramic plate is applied to open curtain walls, and is mostly used in high-rise building curtain walls or even super high-rise building curtain walls, and is subjected to corrosion and water immersion in the environment of irradiation and strong wind and rain for a long time, so there is also a possibility of falling during use. Therefore, higher requirements are put forward for the strength and corrosion resistance of the ceramic plate, otherwise there is a great safety hazard.

[0004] The nozzle is the final extrusion forming port of the ceramic plate blank, which promotes the close combination of the clay into the brick and tile blank. Its main function is to obtain a blank with high density, good mechanical strength, smooth surface, low water content and certain shape and size. The larger the flow area of the inner cavity of the nozzle and the smoother the surface, the more conducive to the flow of ceramic clay, and the less the extrusion forming force required. On the contrary, the smaller the flow area of the inner cavity of the nozzle and the rougher the surface, the more difficult the flow of the clay, and the greater the extrusion forming force required. Process modification from the extrusion port is also a research direction for improving the quality of the ceramic plate.

[0005] Therefore, improving the strength and corrosion resistance of terracotta panels is a research topic that needs to be continuously carried out by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to improve the strength and corrosion resistance of ceramic panels by innovating in terms of raw material optimization and preparation process without increasing costs.

[0007] The specific technical solution is as follows:

[0008] A high-strength, corrosion-resistant, and eco-friendly terracotta panel, by weight, comprises 80-85 parts of clay powder, 2-5 parts of iron ore tailings, 5-8 parts of alkali-resistant glass fiber, 2-5 parts of sludge, 1-2 parts of clay powder, and 0.2-0.4 parts of plasticizer.

[0009] Preferably, the clay powder, by mass fraction, is one or more of kaolinite, illite, or montmorillonite.

[0010] Preferably, the composition of the smelting iron ore tailings is (by mass percentage): SiO2: 61.2%–70%, Fe2O3: 6%–9%, ​​Al2O3: 15%–20%, MgO: 1%–4%, CaO: 0.5%–4.5%, TiO2: 0.2%–1.5%, K2O: 0.5%–2.5%, Na2O: 0.1%–4%, with the balance being carbon.

[0011] Preferably, the sludge has an organic matter content of 3%-12% and a sand content of 1-6%.

[0012] Preferably, the plasticizer is water glass.

[0013] Preferably, the raw materials for the terracotta panel, by weight, include 83 parts of clay powder, 4 parts of iron ore tailings, 6 parts of alkali-resistant glass fiber, 4 parts of sludge, 1 part of clay powder, and 0.3 parts of plasticizer.

[0014] The preparation process of the high-strength, corrosion-resistant, eco-friendly ceramic panel includes the following steps:

[0015] (1) According to the proportion, take clay powder, iron ore tailings and alkali-resistant glass fiber and crush each raw material to 200 mesh or more. Then add sludge, clay powder and plasticizer to form mixed raw materials.

[0016] (2) The raw materials and water are mixed in a mixer according to the ratio of water to the mass of the raw materials, which is 15%-20% to obtain wet material.

[0017] (3) The above wet material is fed into a plywood mixing machine for mixing, thereby obtaining a clay material with a plasticity index of 9-12;

[0018] (4) The above-mentioned mud material is fed into a vacuum extruder and shaped through the nozzle and die. While extruding, a titanium ester graphene mixed solution is dynamically and continuously injected into the inner surface of the nozzle and die. After the mud material is extruded, it is cut into the corresponding specifications to obtain a wet blank. The flow rate of the titanium ester graphene mixed solution is 2-3 ml / m².

[0019] (5) Dry the wet green body at a temperature of 40℃-150℃ for 4-8 hours to obtain a dry green body;

[0020] (6) The dry blank is sent into the firing kiln and sintered at a temperature of 1000℃-1140℃ for 3-5 hours.

[0021] (7) Cool the ceramic plate.

[0022] Preferably, the method for preparing the titanate-graphene mixed solution in the above process step (4) is as follows: graphene oxide is completely dispersed in water, titanate coupling agent is added and mixed evenly to obtain a mixed solution with a viscosity of 2000-4000 cps (25℃) and the mass ratio of graphene oxide to titanate coupling agent is 4:1-2.

[0023] Preferably, the drying method of the above process step (5) is: first dry at 40-50℃ for 3-5 hours, then dry at 51-80℃ for 0.5-2 hours, and then dry at 81-150℃ for 0.5-1 hour. The sintering method of step (6) is: 1000-1050℃ for 1-2 hours, and 1051-1140℃ for 2-3 hours.

[0024] Preferably, the cooling method of the above process step (7) is as follows: transfer the ceramic plate to the cooling room, cool the ceramic plate to 300-600℃, maintain the ambient temperature at 200-300℃ for 2-3 hours, lower the ambient temperature to 100-200℃ for 2-3 hours, and then cool naturally.

[0025] The beneficial effects of this invention are as follows:

[0026] (1) This invention uses industrial solid waste, iron ore tailings and sludge combined with ceramic wood powder as raw materials to prepare ceramic slabs. Glass fiber is also incorporated. This technical solution employs a high-silicon, low-alumina, high-potassium-sodium formulation system and specific plasticizers to optimize the ceramic slab formula, improve the fluidity of the clay, and facilitate the extrusion forming of the ceramic slab blank. The resulting ceramic slab has high strength and good corrosion resistance, greatly improving its performance and making it safer and more widely applicable during application and construction.

[0027] (2) When the raw material formulation contains a higher content of plastic material, the required extrusion molding pressure is lower, but the drying and sintering shrinkage deformation of the green body is greater; conversely, when the ceramic raw material formulation contains a lower content of plastic material, i.e., a higher content of lean material, the drying and sintering shrinkage deformation of the green body is obviously smaller, but the required extrusion molding pressure is greater. The ratio range of plastic material and lean material in the raw material formulation of this invention is appropriate, and the required extrusion molding pressure and the drying and sintering shrinkage deformation of the green body are moderate.

[0028] (3) In the preparation process described in this invention, the drying, sintering and cooling processes all adopt a stepped temperature method, which can be combined with the characteristics of the blank to reduce the quality defects such as cracks and bending of the prepared clay.

[0029] (4) Surface treatment of ceramic substrate is a key step to improve the quality and performance of ceramic substrate. In this technical solution, a mixed solution of titanate graphene is dynamically injected into the extrusion mold during the extrusion process, which can reduce the interference of the mold surface on the ceramic substrate surface and help to ease the extrusion pressure of the clay material, making the ceramic substrate surface smoother and cleaner.
