| titleOfInvention | Castor oil modified benzoxazine resin and preparation method thereof |
| abstract | The invention relates to a castor oil modified benzoxazine resin and a preparation method thereof. A castor oil modified benzoxazine resin is obtained by carrying out one-step reaction on diisocyanate, castor oil and a bis-hydroxymethyl benzoxazine monomer and then carrying out crosslinking curing. Preparation: uniformly mixing castor oil and a bis-hydroxymethyl benzoxazine monomer in a solvent, wherein the ratio of cyanate groups in diisocyanate to total hydroxyl groups in the castor oil and the bis-hydroxymethyl benzoxazine monomer is 1: 1, slowly dripping diisocyanate into the reaction solution for reaction, and cooling to obtain a castor oil-based polyurethane benzoxazine prepolymer; and curing the obtained prepolymer solution to obtain the castor oil modified benzoxazine resin. The modified benzoxazine resin prepared by introducing castor oil which is a natural renewable resource as a raw material has good compatibility, flexibility and excellent dielectric property, and the synthesis process is simple. |
