Preparation method of graphite magnesium silicate system conductive material
The invention provides a preparation method of a graphite magnesium silicate system conductive material. The graphite doping amount in the magnesium silicate system exceeds the percolation threshold value by doping the dispersing agent and independently calculating the graphite dispersion water requirement, the preparation process is simple, efficient, environmentally friendly and low in cost, and the prepared graphite/magnesium silicate system conductive material is excellent in conductivity, stable in structure and suitable for industrial production. And good flowability and strength are still maintained when the graphite doping amount is high. The preparation method comprises the following steps: carrying out dry mixing and stirring, preparing a dispersion solution, preparing a graphite dispersion liquid, pulping, molding, maintaining and the like to obtain the normal-temperature graphite/magnesium silicate system conductive material, and when the graphite doping amount of the obtained product is 30%, the resistivity is less than 1.37 omega.cm, the strength retention coefficient is 0.49, and the fluidity reaches 202 mm. The method has important significance for preparing a cement-based conductive material, improving the conductivity of the magnesium silicate cement and increasing the added value of a building material.
