| titleOfInvention | Aldehyde-free odorless environment-friendly and transparent polyvinyl alcohol (PVA) glue and preparation method thereof |
| abstract | The invention relates to aldehyde-free odorless environment-friendly and transparent polyvinyl alcohol (PVA) glue and a preparation method thereof, and can effectively solve the problem of complex technology or containing of harmful substances such as aldehydes in the prior art. The technical scheme includes that the glue is produced by the PVA, water, a modifier and a preservative, wherein, by weight, the PVA accounts for 1-15% of the glue, the modifier accounts for 0.5-10% of the PVA, the preservative accounts for 0.01-0.05% of the PVA and the balance water. The method includes mixing the PVA with the water at a room temperature of 18-25 DEG C, heating up to 85-100 DEG C after evenly stirring, cooling to 45-80 DEG C after completely dissolving, adding in the modifier and modifying for 0.5-2 hours at a temperature of 45-85 DEG C, cooling to the room temperature of 18-25 DEG C, adding in the preservative, and obtaining the glue. According to the PVA glue and the preparation method thereof, the reaction condition is relatively mild, the operation is simple, the glue is aldehyde-free, odorless, transparent, innovative, high in viscosity, low in production cost and prone to industrial production. |
