Production method of washing machine balancing weight

The invention provides a production method of a washing machine balancing weight. The method comprises the steps that 15 parts of slags, 12 parts of cement, 8 parts of waste metal scrap granules, 2 parts of gravels and 5 parts of carborundum are mixed, a proper amount of water is added for stirring to form slurry, and the slurry is poured into a mold to form a foundation balance weight core; 45 parts of high-purity acrylic acid and 20 parts of sodium hydroxide are neutralized in water to be cooled, 10 parts of plant starch and 0.3 part of potassium persulfate are added for stirring, nitrogen is introduced, heating is performed to 40 DEG C, 10 parts of dialkyl siloxane, 4.5 parts of alkyl acrylate, 3 parts of acrylonitrile, 1 part of chloroprene, 2.5 parts of vinyl fluoride and 4 parts of vinyl acetate are added in sequence, heating is performed to 75 DEG C, the temperature is kept constant, and stirring is performed for 20 min to obtain adjusting balance weight castable, the castable is poured into a mold, the foundation balance weight core is completely soaked in the adjusting balance weight castable, and cooling and solidification are performed to obtain the balancing weight. The balancing weight has the good water absorption, the weight of the balancing weight can be increased after water is absorbed, and the weight of the balancing weight is decreased after water is lost.
