| titleOfInvention | Preparation method of foam inhibiting and antifoaming agent for polyvinyl alcohol (PVA) aqueous solution |
| abstract | The invention relates to a preparation method of a foam inhibiting and antifoaming agent for a polyvinyl alcohol (PVA) aqueous solution. The foam inhibiting and antifoaming agent for the PVA aqueous solution consists of the following components in parts by weight: 30-50 parts of a main antifoaming and foam breaking agent, 1-5 parts of a synergistic antifoaming agent, 3-5 parts of a dispersing and wetting agent, 5-10 parts of a solubilizing agent and 40-60 parts of water, and is a mixture which is dispersed into water and is mixed by dispersing in a way of stirring at a high speed at the temperature of 80-95 DEG C for 30 minutes. The foam inhibiting and antifoaming agent prepared with the method is suitable for the preparation process of a high-concentration and high-viscosity PVA aqueous solution, and has excellent foam inhibiting and antifoaming functions by being added in the amount of 0.3-1 percent. |
