Abstract

The invention discloses composite physical pigments and fillers with anti-rust and flame-retardant properties and a preparation method thereof, and belongs to the field of utilization of solid waste resources. The pigments and fillers comprise a phosphoric acid solution, steel slag micro powder, graphene, cetyltrimethylammonium bromide, a dilute hydrochloric acid solution and montmorillonite, wherein the steel slag powder is one or more of hot braised slag micro powder, air quench slag micro powder, molten iron desulfurization slag micro powder, casting residual slag micro powder, converter hot splashing slag micro powder, converter drum slag micro powder, electric furnace hot splashing slag micro powder and electric furnace drum slag micro powder. According to the composite physical pigments and fillers with anti-rust and flame-retardant properties and the preparation method thereof, not only is the production cost of existing physical pigments and fillers reduced by 30%-50%, but the anti-rust property, flame-retardant property and adhesive force of the physical pigments and fillers are also improved; the integration of anti-rust property, flame-retardant property and high adhesive force on the physical pigments and fillers is realized; the market competitiveness and application range of the physical pigments and fillers are significantly enhanced; the high value-added application of steel slag and the montmorillonite is expanded; a new thought of using waste to enhancing the effect is realized.

Description

technical field [0001] The invention belongs to the field of utilization of solid waste resources, and in particular relates to a composite pigment and filler with antirust and flame retardant properties and a preparation method thereof. Background technique [0002] Steel slag is solid waste produced in the steelmaking process, accounting for about 15% to 20% of steelmaking output, and its 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, of 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, the stockpiling of a large number of steel slags not only takes up valuable land, but also pollutes the surrounding environment and groundwater. In my country, there are a large number of montmorillonites composed of silicate sheets with nanometer thickness, which mainly include calcium-based montmorillonite, sodium-based montmorillonite, sodium-calcium-b...
