  • Particle defoamer comprising a silicone emulsion and process for preparing same
    Patent number: 9023781
    Abstract: A process for preparing a particle defoamer. The particle defoamer of 55%-75% of a carrier, 15%-35% of a silicone emulsion, 3%-10% of a texturing agent and 2%-10% of a solvent, based on the total weight of the particle defoamer; the process for preparing the particle defoamer is: (1)first adding a carrier A1 into a mixer, and then adding thereto a silicone emulsion B1, and stirring uniformly; (2)adding a carrier component A2 to the mixture obtained in (1), and stirring uniformly; (3)adding a silicone emulsion B2 to the mixture obtained in (2), and, after uniformly stirring, adding the solvent thereto and stirring uniformly; and (4)pelleting and drying by baking the mixture obtained in(3), so as to produce the product.
