A preparation method of an alkaline drainage agent comprises a product formula and manufacturing steps, and the product formula comprises 50%-80% of magnesia, 2%-15% of forsterite, 1%-10% of potassium feldspar, 2%-25% of alumina balls and 0.1%-2% of carbon black. The preparation method comprises the following steps: step 1, screening magnesia, forsterite and potassium feldspar to specified granularity according to the granularity requirement of a product; 2, uniformly mixing the sieved magnesia, forsterite, potassium feldspar and alumina balls in a mixing tank according to a ratio; step 3, adding carbon black into the inorganic binder according to the ratio, uniformly mixing, pouring into the mixing tank, and continuously mixing until the carbon black is uniformly mixed on the magnesia, the forsterite, the potassium feldspar and the alumina balls; and fourthly, drying equipment is started for drying, and the problem that in the steel continuous casting production process in the prior art, the drainage agent r
