In this paper, the result based on the techniques of indoor wood adhesive of Camellia oleifera cake and manufacturing of manmade board suggests that the most appropriate condition of preparation this adhesive is that the solid content is 50%, the reaction temperature is 50 °C, the reaction time is 40min, the dosage of PF resin prepolymer accounts for 50 percent. The pH of the reaction medium is 10 and the dosage of SDBS is 1%. The proper conditions hot pressing process of PF Camellia oleifera cake adhesive for bonding plywood are the hot pressing temperature is 120 ℃, and the hot pressing time is 0.7min/mm (42 s / mm), the gluing amount is 120g/m 2 , and the hot pressing pressure is 1.1MPa. The average water-resistant bonding strength of the plywood prepared under this condition is 0.79mpa, which meets the requirements of class II plate in the national standard GB / T 9846.3-2004. The emission of formaldehyde is 0.38 mg / L, which meets the requirements of class E0 plate in the national standard GB 18580-2001. What’s more, the cost is the lowest among all the techniques.

Optimization of hot-press process and structural characterization of PF Camellia oleifera cake adhesive
