Super-hydrophobic high-specific-strength environment-friendly fiber board and production process

The invention discloses a super-hydrophobic and high-specific-strength environment-friendly fiber board and a production process, belongs to the technical field of fiber board processing, and aims to solve the problems that a fiber board in the prior art is relatively high in hygroscopicity and easy to damp and expand, the compatibility between fibers and matrix resin is poor, and the cost is low. The strength of the fiber board needs to be further improved; and the fiber board does not meet the green and environment-friendly requirements. The polylactic acid composite material comprises the following raw materials in parts by weight: 95-105 parts of polylactic acid powder, 75-85 parts of reinforced fibers, 8-10 parts of an assistant crosslinker, 2-3 parts of an initiator and 1-1.5 parts of an auxiliary additive, the fiber board has good hydrophobicity and specific strength, the mechanical strength of the fiber board is improved, harmful adhesives are not used in the fiber board, the fiber board has good biod
