Embodiment 1

[0037] In this embodiment, the degradable sorting garbage bag is composed of the following components in parts by weight: 60 parts of modified starch, 20 parts of plastic resin, 2 parts of heat stabilizer, 6 parts of biodegradable additive, 4 parts of coupling agent, 4 parts of pigment, 1 part of toughening agent, 2 parts of filler, 0.4 part of antistatic agent, 0.6 part of wear-resistant agent.

[0038] Wherein, the original starch is composed of potato starch and corn starch with a weight ratio of 1:2, and the crosslinking agent is phosphorus oxychloride.

[0039] Described modified starch is prepared by following preparation method:

[0040] S1: Prepare a starch slurry with a concentration of 10%-20%, add the original starch and water of the corresponding parts by weight to the mixer to disperse, control the rotation speed at 1500-1800r / min, heat to 75-80°C, and continue stirring for 30-45min, A starch slurry with a concentration of 10%-20% is obtained;

[0041] S2: Cool ...

Embodiment 2

[0049] In this embodiment, the degradable sorting garbage bag is composed of the following components in parts by weight: 70 parts of modified starch, 10 parts of plastic resin, 2 parts of heat stabilizer, 6 parts of biodegradable additive, 4 parts of coupling agent, 4 parts of pigment, 1 part of toughening agent, 2 parts of filler, 0.4 part of antistatic agent, 0.6 part of wear-resistant agent.

[0050] Wherein, the original starch is tapioca starch, and the crosslinking agent is sodium trimetaphosphate.

[0051] The preparation method of the modified starch and the degradable sorting garbage bag in this embodiment is the same as that in Embodiment 1, and will not be repeated here.

[0052] Prepare degradable classified garbage bags according to the above method, and carry out soil burial test on them. After 80 days, the garbage bags have been degraded, the thickness of the garbage bags has decreased from 0.03mm to 0.02mm, and the tensile strength has decreased from 22.3MPa t...

Abstract

The invention relates to the technical field of plastic products and in particular to a degradable classification garbage bag and a preparation method thereof. The degradable classification garbage bag is prepared from the following raw material in parts by weight: a garbage bag with a two-dimensional code on the surface. The garbage bag is characterized by consisting of the following components in parts by weight: 50-75 parts of a modified starch, 8-20 parts of a plastic resin, 1-2 parts of a thermal stabilizer, 2-8 parts of a biologically degradable additive, 2-4 parts of a coupling agent, 3-6 parts of a pigment, 0.5-1.5 parts of a toughening agent, 1-2 parts of a filling agent, 0.2-0.4 part of an anti-electrostatic agent and 0.4-0.8 part of a wearing resistant agent. The garbage bag provided by the invention can be completely degraded, is free of pollution to the environment, easy in raw material obtaining and low in cost; meanwhile, the garbage bag has a garbage classification function, through the two-dimensional code on the garbage bag, garbage discarded by users can be tracked, good garbage classification habits can be promoted for the users, the cost of garbage classification treatment can be reduced, and good application prospects can be achieved.

Description

technical field [0001] The invention relates to the technical field of plastic products, in particular to a degradable sorting garbage bag and a preparation method thereof. Background technique [0002] Garbage bags are mainly made of plastic, and plastic is extracted from petroleum, and it takes about 200 years for garbage bags to rot when buried in the ground, and it seriously pollutes the soil; if it is incinerated, it will produce harmful smoke and dust And toxic gas, long-term pollution of the environment. In addition, people face the situation of increasing garbage production and deteriorating environmental conditions. How to maximize the utilization of garbage resources, reduce the amount of garbage disposal, and improve the quality of living environment through garbage classification management is an urgent issue of common concern to all countries in the world. one. In view of this, a degradable sorting garbage bag and a preparation method thereof are provided for ...
