preparation example Construction
[0019] The preparation method step of free formaldehyde scavenger is described below:
[0020] 1. Put water, stearamide, sulfuric acid, and sodium polyacrylate into the reaction kettle, stir while heating, control the temperature at 30-60°C, and keep the reaction for 1-3 hours.
[0021] 2. Add nonylphenol ethoxylate, control the stirring speed at 200-300 rpm, and stir for about 30 minutes.
[0022] 3. Finally, dilute sulfuric acid is added to adjust the pH to about 5, and the reaction material is cooled to room temperature, and then filtered and packaged to obtain the finished product.
[0023] Each component weight percentage is respectively in above-mentioned three steps:
[0024] Water: 85~95%
[0025] Stearamide: 5~20%
[0026] Sulfuric acid: 0.1~5%
[0027] Sodium polyacrylate: 0.1~3%
[0028] Nonylphenol ethoxylate: 0.5-12%
Embodiment 1
[0030] In 100 parts of water in this example, add 8 parts of stearamide, 0.5 part of sulfuric acid, 0.5 part of sodium polyacrylate, and 0.6 part of nonylphenol ethoxylate, and stir and react under the condition of 30-60 °C, and keep warm for 1-3 Hours later, the finished product can be obtained by filtration, a colorless and transparent free formaldehyde scavenger.
Embodiment 2
[0032] In 100 parts of water in this example, 10 parts of stearamide, 2 parts of sulfuric acid, 1 part of sodium polyacrylate, and 3 parts of nonylphenol ethoxylate were added respectively, and stirred and reacted at 30-60°C, and kept warm for 1-3 Hours later, the finished product can be obtained by filtration, a colorless and transparent free formaldehyde scavenger.
