Description

technical field [0001] The invention belongs to the field of recycling of solid waste resources, and in particular relates to a steel slag-diatomite composite rubber filler with reinforcing-flame-retardant synergistic performance 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. Steel slag is mainly composed of oxides of calcium, iron, silicon, magnesium and a small amount of aluminum, manganese, phosphorus, etc., that is, SiO 2 , Fe 2 o 3 、Al 2 o 3 , ZnO, CaO, MgO, P 2 o 5 , MnO, SO 3 etc., also contains free calcium oxide and metallic iron. Diatomaceous earth is a siliceous rock whose main chemical composition is SiO 2 , due to the high impurity content, it cannot be used directly and requires deep processing. At present, a large amount of steel slag and diatomite are stockpiled, which not only takes up valuable land, but also pollut...
