Guided periodontal tissue regeneration barrier membrane and preparation method thereof

The invention belongs to the technical field of preparation of barrier membranes for guiding periodontal tissue regeneration, and discloses a barrier membrane for guiding periodontal tissue regeneration and a preparation method thereof. Calcium bicarbonate is rapidly prepared through the calcium bicarbonate preparation method, and the problem that calcium bicarbonate is difficult to synthesize in a solution is solved; the prepared calcium bicarbonate is high in purity; through the ethanol preparation method, the problems that rice husks are hard, the crushing difficulty is high, and the crushed powder contains a large amount of rice husk components to cause great abrasion to equipment in the traditional fully-crushed fermented rice husks are avoided. Meanwhile, enzymatic hydrolysate obtained after rice husks are subjected to steam explosion pretreatment is used as material stirring water in the liquefaction process, the raw material utilization rate is increased, meanwhile, the defect that the cost is too hig
