Embodiment 1
[0017] The formaldehyde-free adhesive used in this example is made of soybean defatted protein powder, PPE, urea, polyether, sodium hydroxide, ethylene glycol, and silicone oil. Raw material of natural coconut palm fiber: moisture <15%, impurity <3%, length 5-25cm.
[0018] 1. Preparation of formaldehyde-free adhesive: Add metered water in sequence to the glue mixer, dry basis content of 0.1% urea, 0.1% polyether, 0.01% sodium hydroxide, 0.5% ethylene glycol, 0.1% Silicone oil, 29.19% PPE, 70% soybean defatted protein powder, and stir well;
[0019] 2. After unpacking, the natural coconut palm fiber filaments are paved to a suitable thickness by the paving machine, and needled;
[0020] 3. Glue spraying on the front side and glue spraying on the back side, the amount of glue applied is 10-18% (dry basis);
[0021] 4. Dry in a dryer, the temperature in the drying room is 80-100°C;
[0022] 5. Cutting;
[0023] 6. Hot pressing, the hot pressing temperature is 120-150°C, and ...
