Embodiment 1

[0013] First, prepare 970Kg of red mud, 5Kg of coupling agent, 15Kg of stearic acid and white carbon black; 10Kg;

[0014] Secondly, the red mud is refined into red mud powder, and the red mud powder reaches more than 5000 mesh;

[0015] Finally, add stearic acid, white carbon black, and coupling agent to the red mud powder in turn, and mix well.

[0016] The effect of this embodiment:

[0017] Since red mud is used as the main raw material of rubber reinforcing agent, it is because it contains elements such as Fe, Al, Si, potassium, titanium, arsenic, yttrium, zirconium and niobium, and then adding coupling agent, stearic acid, white carbon black ; Thereby play the effect of reinforcement and environmental protection, therefore, use reinforcing agent of the present invention, not only can play rubber reinforcement effect, can also play the effect of anti-aging, heat resistance and flame retardant, have energy saving and environmental protection, reduce characteristics of co...

Embodiment 2

[0019] First, prepare 1940Kg of red mud, 10Kg of coupling agent, 30Kg of hard acid and 20Kg of white carbon black;

[0020] Secondly, the red mud is refined into red mud powder, and the red mud powder reaches more than 5000 mesh;

[0021] Finally, add stearic acid, white carbon black, and coupling agent to the red mud powder in turn, and mix well.

[0022] The effect of this embodiment:

[0023] Since red mud is used as the main raw material of rubber reinforcing agent, it is because it contains elements such as Fe, Al, Si, potassium, titanium, arsenic, yttrium, zirconium and niobium, and then adding coupling agent, stearic acid, white carbon black ; Thereby play the effect of reinforcement and environmental protection, therefore, use reinforcing agent of the present invention, not only can play rubber reinforcement effect, can also play the effect of anti-aging, heat resistance and flame retardant, have energy saving and environmental protection, reduce characteristics of c...

Embodiment 3

[0025] First, prepare 194Kg of red mud, 1Kg of coupling agent, 3Kg of stearic acid and black and white carbon; 2Kg;

[0026] Secondly, the red mud is refined into red mud powder, and the red mud powder reaches more than 5000 mesh;

[0027] Finally, add stearic acid, white carbon black, and coupling agent to the red mud powder in turn, and mix well.

[0028] The beneficial effects of the present invention are:

[0029] Since red mud is used as the main raw material of rubber reinforcing agent, it is because it contains elements such as Fe, Al, Si, potassium, titanium, arsenic, yttrium, zirconium and niobium, and then adding coupling agent, stearic acid, white carbon black ; Thereby play the effect of reinforcement and environmental protection, therefore, use reinforcing agent of the present invention, not only can play rubber reinforcement effect, can also play the effect of anti-aging, heat resistance and flame retardant, have energy saving and environmental protection, reduc...

Abstract

A method for preparing a rubber reinforcing agent from red mud. The method comprises the following steps: first, preparing red mud, a coupling agent, stearic acid and white carbon black in accordance with the ratio of 194:1:3:2; second, refining the red mud into a red mud powder higher than 5000 mesh; and finally adding stearic acid, white carbon black and the coupling agent into the red mud powder, and mixing evenly. The method not only can realize rubber reinforcing effect but also can realize effects of aging resistance, heat resistant and flame retardance, and has characteristics of energy conservation, environmental protection and reduced cost.

Description

technical field [0001] The invention belongs to the technical field of rubber production, and in particular relates to a preparation method of using red mud to make a rubber reinforcing agent. The red mud used in the production of tailings in the aluminum industry is used as the main raw material, and then refined and processed into powder and chemical additives are added. After proportioning, it can be directly added to products made of rubber, so as to achieve the reinforcing effect of rubber and anti-aging performance. Background technique [0002] For a long time, the tailings slag produced by enterprises that manufacture and smelt non-ferrous metal aluminum—red mud has been hoarded like a mountain, and it is very difficult to further digest and utilize it, thus seriously polluting the local air and water sources. During the 12th Five-Year Plan period, the state issued a series of preferential policies to encourage scientific research and public relations, and effectivel...
