Background
The high-silicon bauxite isAluminum-silicon ratio (Al)2O3/SiO2) Lower bauxite, due to its lower alumina content and acidity, results in higher production costs and poor product quality of desiliconized refined alumina, and therefore is discarded in large quantities. The dust mud kiln slag is metallurgical solid waste generated after zinc oxide rotary kiln treatment of zinc-containing intermediate material, and the main chemical component of the dust mud kiln slag is Fe2O3、CaO、SiO2It is alkaline. The phosphorus slag, the magnesium slag and the semi-dry desulphurization ash are common industrial solid wastes, wherein the phosphorus slag is alkaline and mainly comprises CaO and SiO2、P2O5(ii) a The magnesium slag is alkaline, and the main components of the magnesium slag are CaO and SiO2MgO; the semidry desulfurized fly ash is alkaline and comprises the main components of CaO and SiO2. At present, the utilization rate of high-silicon bauxite, phosphorus slag, magnesium slag, semidry desulfurization ash and dust mud kiln slag is low, and a large amount of high-silicon bauxite, phosphorus slag, magnesium slag, semidry desulfurization ash and dust mud kiln slag are piled up in the open air, so that not only is precious land occupied, but also the surrounding environment and underground water are polluted. Therefore, how to utilize high-silicon bauxite, phosphorus slag, magnesium slag, semidry desulfurization ash and dust mud kiln slag in a large scale and high efficiency to realize environment reduction and enterprise synergy is an urgent problem to be solved.
The paint is mainly prepared from base materials, a solvent, pigment and filler and an auxiliary agent, wherein the pigment and filler not only can play a role in coloring and filling, but also can effectively improve the storage stability of the paint and the related properties of a paint film, such as the durability, the heat resistance and the wear resistance of a paint film are improved, and the shrinkage of the paint film is reduced. The pigment and filler used in the antirust coating mainly comprises antirust pigment and filler, coloring pigment and filler and body pigment and filler, and the three pigments and fillers have different functions in the antirust coating, namely the antirust pigment and filler mainly play a role in enhancing the corrosion resistance of the antirust coating, so that the service life of the antirust coating is prolonged; the coloring pigment and filler mainly play a role in coloring, so that the antirust coating has a specific color; the body pigment and filler mainly play a role in filling, so that the solid content and the coverage rate of the antirust coating are improved. At present, the main antirust coating pigments and fillers mainly comprise iron oxide, micaceous iron oxide, chromium oxide, zinc oxide, titanium oxide, lithopone, calcium carbonate, talc, nano clay and the like, but the pigments are expensive and have single functionality, namely poor multifunctional integration.
