| titleOfInvention | Water-based self-dispersion thermosetting phenolic resin and preparation method thereof |
| abstract | The present invention belongs to the field of high polymer material. Naphthol sulfonate is introduced into the main chain of the resin molecule to endow the resin system with water solubility; adopting a mixed system of phenol and naphthol sulfonate and synthesizing under the condition of a divalent metal ion catalyst. The invention relates to a water-based self-dispersion thermosetting phenolic resin, which is prepared by catalyzing by divalent metal ions and spraying formaldehyde in batches, wherein a material system contains naphthol sulfonate and comprises the following components: 1 part by mole of phenol, 10-20% of naphthol sulfonate, and the molar ratio of phenol to formaldehyde is 1: 1.5-2.0 parts of water, 14-24 parts of water and 0.5-5 parts of divalent metal ion catalyst. The water-based self-dispersion thermosetting phenolic resin has good water dispersibility, good storage stability and higher cohesiveness and temperature resistance, is suitable for being used as a water-based thermosetting structural adhesive with high shear strength and high temperature resistance, and is particularly suitable for adhering phenolic composite materials and steel in brake pads. |
