摘要

In this study corn husk used as raw material, and achieved corn husk fiber through degumming properly. Then degradable fiberboard can be obtained with husk fiber and polylactic acid particles through blending and hot pressing. Taking mass fraction and length of corn husk fiber, hot-pressing time and temperature as factors, and taking tensile, bending and impact strength as index, through the L9 (34) orthogonal testing and range analyzing and achieved the optimal process parameters is: corn husk fiber mass fraction is 50%, corn husk fiber length is 10 mm, hot pressing time is 6 min, hot pressing temperature is 180°C. Under the optimal process condition, a optimal fiberboard is obtained, whose tensile strength is 69.32 MPa, bending strength is 90.26 MPa, impact strength is 18.5 KJ/m2. The conclusion of this paper provides the theoretical guidance for the reuse technology of corn husk fiber.
