| titleOfInvention | A kind of preparation method of benzoxazine-epoxy resin |
| abstract | The invention discloses a kind of preparation method of benzoxazine-epoxy resin, it is characterized in that: aminated compounds, solvent, formalin are joined in reactor, 0 ~ 30 DEG C of stirring reaction 1 ~ 2 hour, add phenolic compound, 85 ~ 95 DEG C of back flow reaction 2 ~ 4 hours, again catalyzer and alkaline phosphatase hydrogen disalt are added, under agitation add part aqueous hydrogen peroxide solution, stirring reaction is after 1 ~ 2 hour, add remaining aqueous hydrogen peroxide solution again, at 60 ~ 90 DEG C, react 3 ~ 16 hours again; Be cooled to room temperature, leave standstill 2 ~ 8 hours, the organic phase isolating top is benzoxazine-epoxy resin product.Present method adopts the benzoxazine resin of an autoclave interfacial synthesis method anamorphic zone epoxide group, concise in technology, and cost is low; Obtained benzoxazine-epoxy resin can be widely used in the field such as glass fibre fabric swatch (pipe), glasscloth preimpregnation material identical with common epoxy or resol. |
