Description

Technical field [0001] The invention belongs to the field of solid waste resource utilization, and specifically relates to a metallurgical solid waste pigment and filler integrating flame retardancy, anti-rust and physical properties and a preparation method thereof. Background technique [0002] Steel slag is a solid waste produced during the steelmaking process, accounting for approximately 15% to 20% of steelmaking output. The main components are CaO, Fe 2 O 3 ,Al 2 O 3 ,SiO 2 ,MgO,P 2 O 5 , MnO, SO 3 and a small amount of free calcium oxide, among which CaO (35.0% ~ 55.0%), Fe 2 O 3 (10.0%~35.0%), Al 2 O 3 (2.0% ~ 12.0%) content is relatively high. Laterite nickel slag is a non-metallic mineral composed mainly of non-metallic minerals produced after acid leaching of laterite nickel ore to recover metal minerals. Its main chemical composition is SiO 2 ,CaO,Al 2 O 3 , MgO, MnO, Cr 2 O 3 , FeO, etc., among which SiO 2 (28.2%~29.3%), CaO (26.8%~28.0%), Al 2...
