| titleOfInvention | Production method of polycaprolactone glycol modified phenolic resin foam |
| abstract | The present invention introduces a production method of polycaprolactone diol modified phenolic resin foam, which adopts the following raw materials and steps: (1), backup caprolactone, ethylene glycol, zinc acetate, phenol, paraformaldehyde, hydrogen Sodium oxide, water; (2), drop caprolactone, ethylene glycol, zinc acetate into the reactor to generate polycaprolactone diol; (3), drop phenol, sodium hydroxide and water into another reactor to generate hydroxyl Methyl phenol; (4), put in polycaprolactone diol to obtain a phenolic resin with a linear structure; (5), vacuum dehydration; (6), inject a preset mold to obtain a finished product of polycaprolactone diol modified phenolic resin foam . The method utilizes the ester group and long carbon chain structure on polycaprolactone, overcomes the defects of high brittleness, easy pulverization and poor mechanical properties of traditional phenolic resin foam, reduces the brittleness of the product, improves the performance, and achieves both increased strength and reduced mechanical properties. brittle effect. |
