| titleOfInvention | A kind of polyvinyl alcohol composite hydrogel and preparation method thereof |
| abstract | The present invention relates to a kind of polyvinyl alcohol composite hydrogel and preparation method thereof, the component raw material comprising following weight parts proportioning is composited by the boric acid aqueous solution crosslinking curing containing solidifying agent: polyvinyl alcohol 30 ~ 90 parts, sodium alginate 0.1 ~ 50 part, inorganic nano-particle 0.1 ~ 20 part, elastomer material 1 ~ 20 part, coupling agent 0.5 ~ 5 part, 200 ~ 2000 parts, water; The polymerization degree of wherein said polyvinyl alcohol is 400 ~ 3000, and alcoholysis degree is 75 ~ 99%; The present invention adopts polar elastomers material, through the inorganic nano-particle of coupling agent treatment and polyvinyl alcohol compound, by playing the toughening effect of elastomer material and the reinforcing effect of inorganic nano-particle, thus improve polyvinyl alcohol hydrogel mechanical strength and toughness, increase the service life, meet the actual requirement used mechanical property; The preparation method of described polyvinyl alcohol composite hydrogel, technique is simple, and processing ease, is suitable for large-scale production. |
