Abstract

The invention discloses a composite body pigment and filler with antirust and flame retardant properties and a preparation method thereof, belonging to the field of solid waste resource utilization. The pigment and filler include phosphoric acid solution, steel slag fine powder, graphene, cetyltrimethylammonium bromide, dilute hydrochloric acid solution and montmorillonite. The steel slag fine powder is one of hot stuffy slag fine powder, wind quenching slag fine powder, molten iron desulfurization slag fine powder, casting residual slag fine powder, converter hot slag fine powder, converter drum slag fine powder, electric furnace hot slag fine powder, electric furnace drum slag fine powder or more. The invention not only reduces the production cost of the existing body pigments and fillers by 30% to 50%, but also improves the antirust performance, flame retardancy and adhesion of the body pigments and fillers, and realizes the antirust performance, flame retardancy and high adhesion The integration of texture pigments and fillers has greatly enhanced the market competitiveness and application scope of texture pigments and fillers; expanded the high value-added applications of steel slag and montmorillonite, and realized the new idea of ​​"using waste to increase efficiency".

Description

technical field [0001] The invention belongs to the field of solid waste resource utilization, and in particular relates to a composite body pigment and filler with anti-rust and flame-retardant properties and a preparation method thereof. Background technique [0002] Steel slag is a solid waste generated in the steelmaking process, accounting for about 15% to 20% of the steelmaking output. The main components are CaO and 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, of which CaO (35.0% to 55.0%), Fe 2 O 3 (10.0%~35.0%), Al 2 O 3 The content of (2.0% to 12.0%) is relatively high. At present, the accumulation of a large amount of steel slag not only occupies valuable land, but also pollutes the surrounding environment and groundwater. In my country, there are a large number of montmorillonite composed of nanometer-thick silicate sheets, which mainly include calcium-based montmorillonite, sodium-based montmorillon...
