<p>Provided is a method for formulating a high-stability non-ionic N-vinylbutyrolactam iodide solution, comprising dissolving high-stability non-ionic N-vinylbutyrolactam iodide in water, then adding citric acid, a iodine ion stabilizer, a non-ionic surfactant, and an emulsifying agent, and adjusting to pH 5 with a pH adjusting agent. Preferably, the iodine ion stabilizer is potassium iodate, the non-ionic surfactant is Tween 20, the emulsifying agent is polyethylene glycol 200, the pH adjusting agent is sodium hydroxide, and the high-stability non-ionic N-vinylbutyrolactam iodide is formed by complexing PVP-K30 and iodine in the presence of a grinding aid at a temperature of 60-90°C. Also provided is a high-stability non-ionic N-vinylbutyrolactam iodide solution formulated by the method. The high-stability non-ionic N-vinylbutyrolactam iodide solution of the present invention has a high stability, which is convenient for long-term storage and use.</p> |
