Abstract

The invention discloses modified ferrochromium slag for flame-retarding reinforced rubber filler and belongs to the field of cyclic utilization of resources. The modified ferrochromium slag comprisesan oxalic acid dihydrate solution, a silane coupling agent KH560, acetone and ferrochromium slag, wherein the mass percent of the oxalic acid dihydrate solution is 80 to 95 percent; the grain diameterof the ferrochromium slag is 4.2 to 113.8mum; the silane coupling agent KH560 is industrially pure; the acetone is analytically pure. By adopting the modified ferrochromium slag, the problems of an existing rubber industry that the price of main filler including carbon black and white carbon black is relatively high and the performance is single, the main filler only has reinforcing performance,the ferrochromium slag is directly added into rubber and is easy to agglomerate, and the compatibility between a ferrochromium slag inorganic interface and a rubber organic interface is relatively poor are solved; high-additional-value cyclic utilization of industrial waste mateirals is realized, the increasing of benefits of metallurgical enterprises is promoted and the reduction of the cost of arubber product industry are promoted; current industrial development requirements on energy saving and environment protection and cyclic economy are met.

Description

technical field [0001] The invention belongs to the field of resource recycling, and in particular relates to a modified ferrochrome slag used for flame-retardant reinforcing rubber fillers and a preparation method thereof. Background technique [0002] Ferrochrome slag is chromium-containing waste slag produced when chromium-containing ferroalloys are smelted by pyrometallurgy. It is mainly produced when high-carbon ferrochrome is smelted by submerged arc furnace method. Its main chemical composition is SiO 2 , Fe 2 o 3 、Al 2 o 3 , CaO, MgO, Cr 2 o 3 , SO 3 ,P 2 o 5 etc., where Al 2 o 3 And the content of MgO is higher. At present, ferrochrome slag is mainly used as cement raw material. Its production process pollutes the surrounding environment and has low added value. Therefore, how to use ferrochrome slag efficiently and with high added value to reduce environmental burden and increase enterprise efficiency is an urgent task. issues that need resolving. [0...
