Abstract

The invention discloses a preparation method for a modified bamboo fiber-polylactic acid composite used for automobile interior trims. The preparation method comprises the following steps: (1) degumming of bamboo fiber; (2) modification of the bamboo fiber through microbial fermentation: preparing a composite bacterial strain from Bacillus licheniformis, Bacillus amyloliquefaciens and Acetobacter xylinum according to an amount ratio of 1: (0.3-0.5): 0.8, washing the degummed bamboo fiber, uniformly sprinkling the composite bacterial strain, carrying out fermentation at 38 DEG C for 50 to 96 h, then carrying out washing with warm water after completion of fermentation, and carrying out fluffing and drying; (3) blending of raw materials: carrying out preheating at 160 DEG c for 1 hr and preparing dried raw materials consisting of the modified bamboo fiber, polylactic acid, chitosan powder, nanometer talcum powder and calcium carbonate; (4) pre-presing; and (5) hot-pressing molding.
