【Abstract】 A preparation method of active phenol formaldehyde resins as crosslinking agent for tannin adhesives was introduced. Specific characteristics of the active phenol formaldehyde resins prepared were determined by chemical analysis and￣(13)C NMR respectively. The crosslinking reactions between tannin and PF resins were studied by DSC and laboratory scale plywood experiment was carried out.更多还原
