Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a formula of carbon material impregnating agent and its preparation and application process. The carbon material impregnating agent can be used to make the impregnating agent organized and completely Immerse into the internal pores of the carbon anode to solve the problems of too long immersion time, insufficient immersion depth, high raw material cost and unsatisfactory product purity in the existing anode impregnation technology. It can effectively penetrate the pores and effectively deal with the problem of ineffective oxidation and slag falling in the pore channels of the anode carbon block

Embodiment 1

[0031] A carbon material impregnating agent. The impregnating agent is a glue solution prepared by mixing carbon materials, treatment agents and water. The specific raw material ratio is as follows:

[0032] 1. A carbon material with a total mass fraction of 30%, including 25% carbon black and 5% graphite powder;

[0033] 2. The total mass fraction is 6% of the treatment agent, including 2% of the oxidant hydrogen peroxide, 2% of the coupling agent vinyltriethoxysilane, 1% of the dispersant fatty alcohol polyoxyethylene ether sodium sulfate and 1% thickener aluminum silicate;

[0034] 3. 64% water.

[0035] Its process method concrete steps are as follows:

[0036] A. Calculate and weigh the raw material of the carbon material according to the requirements of the formula, and mix it with the dispersant to obtain the mixture I;

[0037] B. Transfer the mixture I to a ball mill for ball milling, use a medium ball with a diameter of 0.5 mm, set the rotor speed to 80 r / min, and...

Embodiment 2

[0047] The impregnating agent is a treatment agent with a total mass fraction of 35% of carbon materials (including 30% of carbon black and 5% of graphite micropowder) with a total mass fraction of 6.5% (including 2.3% of hydrogen peroxide oxidant, vinyl three 2.3% ethoxysilane coupling agent, 1.3% fatty alcohol polyoxyethylene ether sodium sulfate dispersant, 0.6% aluminum silicate thickener) and 58.5% water. Its processing method concrete steps are with embodiment 1.

[0048] The obtained air reactivity test results show that the loss rate of the anode carbon block is 4.32%, the residual rate is 95.25%, and the shedding degree is 0.52%; the current density test result is 1.31 A / cm2.

Abstract

The invention discloses a carbon material impregnant formula and a preparation and application process thereof. An impregnant is a glue solution prepared by blending 1-60 wt% of a carbon material, not more than 10 wt% of a treating agent and water according to a certain proportion, the carbon material is a mixture composed of carbon materials with different particle sizes, the treating agent comprises an oxidizing agent, a coupling agent, a dispersing agent and a thickening agent. According to the invention, the composition of the carbon material can be adjusted according to the pores of different anode carbon blocks, so that the carbon materials with different particle sizes are organized to fill the corresponding pores, and thus the density and weight of the anode carbon blocks are increased and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of an impregnating agent for carbon or graphite materials mixed and pressed with one or more raw materials of graphite, carbon powder, petroleum coke and pitch coke and sintered, especially an anode for electrolytic aluminum The carbon block impregnating agent specifically relates to a carbon material impregnating agent formula and its preparation and application process. Background technique [0002] Electrolytic aluminum carbon anodes generally use various cokes as the main raw materials. The coke itself has a honeycomb or fiber macrostructure, and there are pores with different pore sizes on the surface and inside. Pyrolysis will occur and volatilization escapes, which also leads to the formation of irregular air outlet holes inside the anode. In short, after the prebaked anode carbon block is produced, there will be a large number of pores inside the carbon block. In order to improve the service life o...
