摘要： Disclosed are a bamboo outer skin-retaining bamboo veneer and a preparation process thereof, belonging to the technical field of bamboo processing. The preparation process includes the following steps: segmenting bamboo and cutting into bamboo strips with an arc-shaped section; softening the bamboo strips by pressurizing and heating, and unfolding the softened bamboo strips at equal arc and fixed thickness; performing double-sided protection and gradual flattening under a condition of heat preservation until the bamboo strip is completely flattened, to obtain a bamboo board; and continuously cooling the bamboo board, shaping the bamboo board under a heavy weight and then drying, and then trimming under a fixed width to obtain the bamboo outer skin-retaining bamboo board finished product. The bamboo outer skin-retaining bamboo strip can be unfolded under the promise of not destroying the bamboo outer skin surface, and there will be no cracking and rebound problems.
