s2, adding the mixed solution in the S1 into a thickening agent, stirring and mixing for 3-5min, and finally adding a bactericide and a mildew preventive to prepare a liquid A;
s3, weighing the raw materials in the powder B, crushing the raw materials by a coarse crusher, screening the crushed raw materials by a 600-mesh screening sieve, and continuously crushing the raw materials which are not completely crushed;
s4, finely crushing the completely crushed raw materials by a fine crusher, secondarily screening the crushed raw materials by a 1200-mesh sieve, not secondarily crushing the raw materials by the 1200-mesh sieve, and mixing and stirring the raw materials passing through the 1200-mesh sieve to prepare powder B;
