Abstract: Lignin phenolic resin (LPF) mixed with common phenolic resin (PF) at certain mass ratio were added with fillers and additives to plasticate, grinded into LPF molding power, and then were pressed to products. The results of property test showed that the product with 60% mass fraction of LPF (LPF-60) had better physical properties, flexural strength is 78.0 MPa, impact strength is 3.65 kJ/m2 and heat deflection temperature is 174.03℃. The TG analysis showed that the molding power had better heat resistance, mass loss were 8.89%, 58.16% and 93.39% at 400, 800 and 1000℃, respectively.

Key words: lignin phenolic resin, molding power, property
