Problems solved by technology

[0003] Most of the urban residents in our country use disposable garbage bags or plastic bags obtained from supermarkets and vegetable markets to hold all kinds of garbage. Since this kind of plastic bag has only accommodating function, it can only hold waste in the bag, and because of waste Food waste, especially kitchen waste, often contains a lot of soup, which will cause the garbage to ferment when mixed with the garbage, resulting in an unpleasant smell

Embodiment 1

[0015] The water-absorbing environmental protection garbage bag comprises the following components by weight: 20 parts of linear low-density polyethylene, 10 parts of low-density polylactic acid, 10 parts of potassium sorbate, 8 parts of water-absorbing masterbatch, and 5 parts of plasticizer.

[0016] The water-absorbing masterbatch is starch acrylate polymer.

[0017] The present invention also provides a production method of the water-absorbing environmental protection garbage bag, the steps of which are:

[0018] (1) Weigh the raw materials according to the above weight ratio;

[0019] (2) Put the above raw materials into the plastic refining machine, and heat them at 130°C for 18 minutes to obtain plasticized hot materials;

[0020] (3) The above-mentioned plasticized hot material is conveyed to the extruder through the screw conveyor. The temperature of the rotating die in the center of the extruder is 150°C. It is blown and formed by extrusion, and the over-temperature...

Abstract

Water-absorbing environmental protection garbage bag, comprising the following components by weight: 20-30 parts of linear low-density polyethylene, 10-15 parts of low-density polylactic acid, 10-14 parts of potassium sorbate, 8-10 parts of water-absorbing masterbatch, plasticized 5-10 doses. The beneficial effects of the invention are that adding water-absorbing masterbatch makes the garbage bag have a certain water-absorbing function, separating the soup and water in the domestic garbage, and adding low-density polylactic acid can be higher than 55 ° C or in the role of oxygen-enriched and microorganisms. It will be automatically decomposed under the hood, the discarded polylactic acid film is in the discarded environment, and the production method is simple, the cost is low, and it is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a water-absorbing environmental protection garbage bag. Background technique [0002] Garbage bags made of polyethylene are light, thin, impermeable, strong, and low in cost. The consumption is increasing, and the waste garbage bags after use are not easy to recycle and degrade. A large number of waste garbage bags have become a serious problem of current environmental pollution. In order to reduce the pollution of garbage bags to the environment, some degradable garbage bags have been developed. [0003] Most of the urban residents in our country use disposable garbage bags or plastic bags obtained from supermarkets and vegetable markets to hold all kinds of garbage. Since this kind of plastic bag has only accommodating function, it can only hold waste in the bag, and because of waste Food waste, especially kitchen waste, often contains a lot of soup, which will caus...
