| titleOfInvention | Modified phenolic resin adhesive and preparation method and application thereof |
| abstract | The invention belongs to the technical field of high polymer materials, and discloses a modified phenolic resin adhesive and a preparation method and application thereof, wherein the modified phenolic resin adhesive is prepared by mixing phenol, melamine and lignin in parts by mass, adjusting the pH value to 9-10 with an alkali solution, and adding formaldehyde A to perform reaction I to obtain a product C; heating to 88-94 ℃, adjusting the pH to 10-12 with an alkali solution, and reacting II to obtain a product D; cooling to 70-90 ℃, adjusting the pH value to 10-12 by using an alkali solution, and adding formaldehyde B to react to obtain a product E; then heating to 88-94 ℃ to react until the viscosity is 100-300 mPas, and cooling to obtain the product. The wood glue consisting of the adhesive and the composite curing agent is rapidly cured at 90-100 ℃, so that the curing temperature is obviously reduced, the production efficiency is improved, and the wood glue is applied to the field of filling pipelines with artificial boards or wood. |
