Platelet-rich fibrous protein composite membrane as well as preparation method and application thereof

The invention belongs to the technical field of preparation of platelet-rich fibrous protein composite membranes, and discloses a platelet-rich fibrous protein composite membrane as well as a preparation method and application thereof. High-quality chitosan can be prepared through the chitosan preparation method, so that the quality of the composite membrane is greatly improved; meanwhile, a mixed solution of an ammonium chloride solution and a calcium chloride solution is prepared through a calcium chloride preparation method; lime powder is added for double decomposition reaction, the temperature of the mixed solution of the ammonium chloride solution and the calcium chloride solution prepared in the first step in the reactor is maintained at 86 DEG C, and the lime powder is added into the mixed solution; the ammonia distillation is performed after lime powder is added for double decomposition reaction in the second step; the mother liquor is treated to prepare high-purity calcium chloride, so that the prep
