Abstract

The invention relates to a rat-proof biobased garbage bag and a preparation method thereof. The rat-proof biobased garbage bag comprises the following components in parts by mass: 20-70 percent of polyethylene, 15-60 percent of starch, 5-10 percent of plasticizer, 5-10 percent of rat-proof repellent and 0.5-2 percent of color master batch. The preparation method of the degradable rat-proof biobased garbage bag comprises the following steps of: preparing a required biobased material from the polyethylene, the starch, the the plasticizer and the rat-proof repellent according to a specific production process; and matching the biobased material with the color master batch and carrying out secondary processing to obtain the degradable rat-proof biobased garbage bag. In the invention, the polyethylene is filled with the thermoplastic starch, so that the thermoplastic starch is uniformly dispersed in a polyethylene matrix; then a polyethylene modified material is disintegrated into fragments along with the biodegradation of the starch, so that the polyethylene modified material has a certain biodegradability; and due to the utilization of the plasticizer, the starch has thermoplasticity, so that the machinability of the starch and the compatibility of polyethylene matrix resin are improved.

Description

technical field [0001] The invention relates to a degradable rodent-proof bio-based garbage bag and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] With the improvement of people's living standards, the concept of garbage bagging has gradually entered people's lives in recent years. Compared with the traditional garbage disposal method, the garbage bag treatment avoids garbage exposure and leakage during transportation, can effectively control the garbage landing, reduce dust in the air, eliminate the breeding grounds of mosquitoes, flies and mice, reduce the spread of various germs, and thoroughly It solves the problem of easy blockage of garbage passages in residential buildings and the odor of garbage after corruption, facilitates the classification and collection of garbage, and finally achieves harmless, resourceful, and reduced treatment of garbage, and is increasingly favored by people. However, most ...
