Abstract: PURPOSE: A multi-wall paper manufactured by mixing starch, clay, silica sol with water is provided which improves the strength degradation of reclaimed corrugated board. CONSTITUTION: A mixture of 3-3.8 weight% of starch, 0.1-0.5 weight% of clay with a particle of 0.1-2 micro meter, 0.1-0.5 weight% of silica sol with a particle of 3-200 nanometers is stirred with 95.2-96.8 weight% of water uniformly to give a slurry adhesive, which is sprayed on the layer of a multi-wall paper with a thickness of 1-4 g/square meter, pressed with the pressure of 2-8 kg/square meter for 1-4 min, and dried at 90-150°C to give a multi-wall paper. Corn, potato and tapioca starch can be used as an organic adhesive ingredient, but corn starch is preferable in the economic and efficiency aspect. The compound improves the adhesive strength of interlayer of the multi-wall paper, the bursting strength and the compressed strength compared with a conventional single spraying process of non-gelatinized starch.
