| titleOfInvention | Multifunctional bio-based epoxy acrylate prepolymer and its preparation method and application |
| abstract | The invention belongs to the field of UV curing materials, and specifically relates to a preparation method of multifunctional bio-based epoxy acrylate, comprising: mixing unsaturated vegetable oil-based carboxylic acid, thioglycolic acid and a photoinitiator, and performing photochemical reaction to obtain vegetable oil-based diacrylate Carboxylic acid. Mix the obtained vegetable oil-based dicarboxylic acid with a certain amount of itaconic acid, add a solvent to dissolve it, then control the temperature, add a tertiary ammonium salt catalyst, then raise the temperature and add resorcinol diglycidyl ether containing a polymerization inhibitor to carry out reaction, then raise the temperature to carry out the reaction, and then slowly add glycidyl methacrylate to continue the reaction to obtain the product. The present invention introduces active double bonds into the main chain of epoxy acrylate, thereby greatly improving its functionality, and utilizes the long chain of fatty acid in vegetable oil-based dibasic acid to have a growth effect on the main chain of epoxy acrylate , which is conducive to enhancing its hydrophobic effect, and through the introduction of biomass benzene rings, it helps to enhance its hardness and reduce the use of petrochemical resources. |
