| titleOfInvention | A fully degradable high-toughness polyvinyl alcohol composite material and preparation method thereof |
| abstract | The invention relates to the technical field of fully degradable materials, and discloses a preparation method of a fully degradable high-toughness polyvinyl alcohol composite material. The modified polyvinyl alcohol, a defoamer, a plasticizer and a leveling agent are melt-blended , and then press the film in a flat vulcanizer to obtain a fully degraded high-toughness polyvinyl alcohol composite material. The modified polyvinyl alcohol is prepared by the reaction of nano attapulgite grafted polypropylene carbonate and polyvinyl alcohol. Nano-attapulgite, polypropylene carbonate and polyvinyl alcohol all have excellent degradation properties. The grafting of nano-attapulgite with polypropylene carbonate to modify polyvinyl alcohol can reduce the hydrophilic properties of polyvinyl alcohol. At the same time, the mechanical properties and thermal stability of polyvinyl alcohol are improved, and the polyvinyl alcohol composite material has the advantages of high toughness, full degradation and good thermal stability. |
