Degradable plastic material for tableware

Abstract

The invention discloses a degradable plastic material for tableware. The degradable plastic material is prepared from the following materials in parts by weight: 110-130 parts of polypropylene, 30-40parts of pine needle meal, 20-30 parts of fruit residue, 25-50 parts of sweet potato starches, 22-30 parts of stuffing, 15-30 parts of calcium fruit fiber, 14-25 parts of peach gum, 5-10 parts of antimicrobial composite, 3-7 parts of plasticizer, 2-7 parts of water-proof agent, 2-5 parts of Bayogenin, 8-16 parts of epoxidized vegetable oil, 10-15 parts of calcium stearate and 100-200 parts of water. In the preparation process of plastic tableware according to the invention, no organic solvent is added, thus, the content of the organic solvent in the plastic tableware is greatly reduced, and the harm of plastic tableware to the human body is reduced. In the process of plastic tableware machining, bayogenin not only can improve the processing performance of polypropylene, but also can adsorborganic solvent carried in raw materials, as a result, the probability of organic solvent permeating food is reduced.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a plastic material for degradable tableware. Background technique [0002] With the rapid development of economy and science and technology, people's life rhythm is getting faster and faster, fast food has become the main work meal for people to go to work, followed by an increase in the use of tableware, disposable plastic tableware on the market now generally use poly Made of polymer compounds such as styrene, polypropylene, polyvinyl chloride, etc. Disposable plastic tableware not only brings us convenience, but also produces a variety of side effects that constitute direct pollution to the human body and secondary pollution to the environment: disposable In the production process of foam tableware, a large amount of foaming agents that are ozone-depleting substances are consumed, which endangers the earth's protective umbrella - the ozone layer. Moreover, polymer compounds such as pol...

[0002] With the rapid development of economy and science and technology, people's life rhythm is getting faster and faster, fast food has become the main work meal for people to go to work, followed by an increase in the use of tableware, disposable plastic tableware on the market now generally use poly Made of polymer compounds such as styrene, polypropylene, polyvinyl chloride, etc. Disposable plastic tableware not only brings us convenience, but also produces a variety of side effects that constitute direct pollution to the human body and secondary pollution to the environment: disposable In the production process of foam tableware, a large amount of foaming agents that are ozone-depleting substances are consumed, which endangers the earth's protective umbrella - the ozone layer. Moreover, polymer compounds such as polystyrene, polypropylene, and polyvinyl chloride are difficult to biodegrade, and the degradation cycle is extremely short. It can last for about 200 years under ordinary environment, thus causing a large amount of white garbage and polluting the environment; at the same time, the existing degradable disposable tableware adds a lot of chemicals, which will decompose when heated, and be discarded. Inhalation of food causes trace pollution to the human body, and long-term deposition damages health; at this stage, some degradable and environmentally friendly tableware are costly
