In order to solve technological problems when urea-formaldehyde （UF） or phenol formaldehyde （PF） resin was used as an adhesive for faced plywood, the author conducted a series of experiments on a modified PF resin by adding melamine urea-formaldehyde （MUF） resin. Then he analyzed the effects of molar ratio of PF and MUF resin, mixture proportion, and hot pressing conditions on viscosity and durability of the modified resin, surface veneer color and bonding performance of the board, and provided the optimum technology parameters for the application of PF resin. Furthermore, the MUF modified PF resin was used to manufacture multi-layer parquet and test results showed the physical and mechanical properties of the parquet could meet demands of the National Standard GB 9846.1-12-88.
