Deodorization easy-to-degrade garbage bag and preparation method thereof

The invention discloses an odor-inhibiting easily-degradable garbage bag and a preparation method thereof, and relates to the technical field of garbage bags. The deodorant is prepared through reaction of 3-formyl-4-methyl hydroxybenzoate, carbon disulfide, hydrazine hydrate, 3-amino-4-hydroxyacetophenone and diamyl cyanamide, growth and reproduction of putrefying bacteria can be inhibited or the putrefying bacteria can be killed, peculiar smell substances can be oxidized, and the garbage bag has the deodorant effect; then, a deodorant, 2-chloroethyl dichlorophosphoric acid, montmorillonite, hydroxyl-terminated polylactic acid, hexamethylene diisocyanate and pentaerythritol are subjected to a reaction to prepare modified polyurethane, the strength of the garbage bag is improved by inhibiting molecular chain movement, meanwhile, combustion is inhibited by blocking, carbonizing and releasing non-combustible gas, and the flame-retardant effect is achieved; and carrying out extrusion blow molding, blanking and he
