Technical Field

The invention belongs to the field of solid waste resource utilization, and particularly relates to a solid waste resource utilization type antirust-flame retardant-physique integrated pigment filler and a preparation method thereof, and the pigment filler can be used in the field of coatings.

Background

The stainless steel slag, the phosphorus slag and the manganese slag are industrial solid wastes, wherein the stainless steel slag is alkaline and mainly comprises CaO and Fe₂O₃、SiO₂And small amount of ZnO, CuO and Cr₂O₃Heavy metal oxides such as PbO; the phosphorus slag is alkaline, and the main components of the phosphorus slag are CaO and SiO₂、P₂O₅(ii) a The manganese slag is alkaline and has CaO and SiO as main components₂MnO; high silicon bauxite is a silicon to aluminum 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. At present, the stainless steel slag, the phosphorus slag, the manganese slag and the high-silicon bauxite have low utilization rate and are piled up in the open air in large quantity, thereby not only occupying valuable land, but also polluting the surrounding environment and underground water. Therefore, how to utilize the stainless steel slag, the phosphorus slag, the manganese slag and the high-silicon bauxite efficiently in a large scale to realize the reduction of the environmental burden and the synergy of enterprises is a problem which needs to be solved urgently.

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.
