▎ 摘　　要

NOVELTY - An easily degradable and environmentally friendly intelligent toilet plastic bag comprises 50-70 pts. wt. corn starch, 8-10 pts. wt. glycerol, 10-20 pts. wt. polyethylene, 10-12 pts. wt. pullulan, 3-6 pts. wt. antioxidant, 20-40 pts. wt. nano-flame retardant compound, 20-40 pts. wt. diethylene glycolpolysuccinate, 10-30 pts. wt. polylactic acid, 20-30 pts. wt. poly(propylene carbonate), 10-20 pts. wt. modified silicon dioxide, 5-10 pts. wt. four-needle shaped zinc oxide crystal whisker, 3-9 pts. wt. graphene oxide, 2-5 pts. wt. plasticizer, 1-3 pts. wt. lubricant, 3-4 pts. wt. dispersant, 6-8 pts. wt. kaolin, and 1-2 pts. wt. UV absorbent. USE - Easily degradable and environmentally friendly intelligent toilet plastic bag. ADVANTAGE - The plastic bag will automatically decompose under the action of oxygen and microorganisms, completely degrades and digests by microorganisms in nature, has excellent degradation performance on carbon dioxide, water and organic fertilizer, simple preparation method, high production efficiency, and easy industrial implementation, and can be produced with ordinary machines. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the plastic bag comprising weighing each component in the raw material, adding into the mixer for mixing uniformly, and banburying for 0.8-1.2 hours; putting the mixed material into a double-screw extruder for melting under the temperature of 180-240 degrees C and extruding the plastic particles; and opening and pressing plastic particles by double-roller plastic refining machine, extruding, and film-blowing.
