| titleOfInvention | Biomass polyurethane adhesive and preparation method thereof |
| abstract | The invention discloses a biomass polyurethane adhesive, which comprises a component A and a component B, wherein the component A is polyurethane prepolymer with an end capped by isocyanate groups, the component B is polyhydroxy compound with an end capped by hydroxyl groups, the molar ratio of the isocyanate groups in the component A to the hydroxyl groups in the component B is N (NCO)/n (OH) 1.1-1.5: 1, the component A consists of oligomer resin A and polyisocyanate; the component B consists of oligomer resin B, polyisocyanate, a coupling agent and an auxiliary agent, wherein the oligomer resin A and the oligomer resin B are mainly prepared by reacting micromolecular polybasic acid and micromolecular polyalcohol through polyester. The adhesive uses pure green biomass raw materials, so that the dependence of polyurethane adhesive raw materials on traditional fossil resources can be reduced, the production energy consumption is reduced, the non-renewable energy consumption is reduced, and the obtained polyurethane adhesive is high in performance, sanitary and safe. The invention also discloses a preparation method of the adhesive. |
