| titleOfInvention | Biological polysaccharide-based waterborne polyurethane material and preparation method thereof |
| abstract | The invention relates to the technical field of high molecular polymer synthesis, and particularly discloses a biological polysaccharide-based waterborne polyurethane material and a preparation method thereof. Adding a rubber-temperature wheel into a glass reactor provided with an electric stirrer, a reflux condenser tube and a digital display thermometer, vacuumizing for 1h at 120 ℃, cooling to 75 ℃, adding 2, 4-toluene diisocyanate and isophorone diisocyanate, dropwise adding triethanolamine and stannous octoate, stirring for 0.5h at 75 ℃, then continuously adding 1, 4-butanediol, acetone and n-pentane, stirring for 1.5h at 75 ℃ to obtain a polyurethane prepolymer, and finally distilling out the acetone under reduced pressure at 58 ℃ and 0.01MPa of vacuum degree to obtain the biological polysaccharide-based waterborne polyurethane material. The preparation method of the biological polysaccharide-based waterborne polyurethane material is non-toxic, pollution-free, economical and reasonable, and can be applied to the fields of biomedicine, pavement slab bottom void, catalyst carriers and the like on a large scale. |
