Abstract

The invention discloses steel slag-micro-silicon powder composite rubber filler with reinforcing-flame retarding cooperative performance and a preparation method thereof and belongs to the field of cyclic utilization of solid waste resources. The filler is prepared from water, a silane coupling agent, steel slag and micro-silicon powder. The preparation method of the filler comprises the followingsteps: firstly, mixing and dispersing the water and the silane coupling agent to obtain a silane coupling agent solution; then mixing the steel slag and the micro-silicon powder and stirring to obtain a steel slag-micro-silicon powder mixture; finally, mixing and stirring the steel slag-micro-silicon powder mixture and the silane coupling agent solution to obtain the steel slag-micro-silicon powder composite rubber filler. According to the steel slag-micro-silicon powder composite rubber filler with the reinforcing-flame retarding cooperative performance, the problems that main filler carbonblack and white carbon black in a rubber industry have a relatively high price and a single function are solved, and the mechanical property and flame-retarding property of rubber are improved; the cyclic utilization of industrial wastes is realized, the benefit increasing of a metallurgical enterprise is promoted and the cost of a rubber product industry is reduced; current energy-saving and environment-friendly and cyclic economy industrial development requirements are met.

Description

technical field [0001] The invention belongs to the field of recycling of solid waste resources, and in particular relates to a steel slag-microsilica powder 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. Micro silicon fume is a ferroalloy. When smelting ferrosilicon and industrial silicon (metal silicon), a large amount of highly volatile SiO is produced in the submerged heat electric furnace. 2 And Si gas, after the gas is discharged, it is rapidly oxidized and condensed with air and prec...
