| titleOfInvention | Preparation method of a special water-absorbing resin for adult diapers |
| abstract | The invention discloses a preparation method of a special water-absorbent resin for adult diapers, comprising raw materials in parts by weight: 30% acrylic acid, 20% sodium hydroxide solution, 60% acrylamide, 5 crosslinking agents, 60% hydroxycyclopentadiene, and deionized Water 60, hydrogen peroxide 0.8, initiator 0.6. Add all raw materials except hydrogen peroxide and initiator to the reactor and mix them evenly, then pass nitrogen gas to remove oxygen; then add initiator to initiate polymerization reaction; keep temperature at 85°C for 2 hours; dry colloidal granulation at 140°C to Moisture content <3%; add 1,4-butanediol evenly to the particles; evenly spray the surface treatment solution on the particles at 140°C for 40 minutes; finally add 30% aluminum sulfate solution and heat at 120°C. The invention has a large water retention capacity, fast absorption speed, flexibility after absorbing water, is not easily broken under pressure, and the water absorbed inside will not be squeezed out due to external force, and is especially suitable for adult diapers. |
