Composite bamboo board and preparation method thereof

The invention discloses a composite bamboo board and a preparation method thereof, and relates to the technical field of material preparation. According to the preparation method disclosed by the invention, the product is prepared by taking bamboo as a raw material and adopting a graded sizing process, so that the waterproof effect of the prepared product is remarkably improved through a microcosmic improvement means on the premise that an aldehyde adhesive is not used, and the problems of mechanical property reduction, size enlargement, particle falling, stinking and the like caused by water absorption or soaking are avoided. 本发明公开了一种复合竹板及其制备方法，涉及材料技术制备领域。本发明所述制备方法以竹材的原料，采用分级施胶的工艺制备产品，在不使用醛类胶粘剂的前提下通过微观层面的改进手段使得制备的产品其防水效果显著提升，避免因吸水或浸泡造成的力学性能下降、尺寸变大程度大、掉粒、发臭等问题。
