Production method of environmental straw

Abstract

The invention provides a production method of an environmental straw. The production method includes the steps of (1) taking, cutting and drying a hollow plant stalk; (2) spraying coating to the inner and the outer surfaces of the dried hollow plant stalk and drying the same; (3) performing sterilization on the dried hollow plant stalk. The plant stalk is high polymer material with fragility and flexibility. According to the arrangement, after physical and chemical processing, the hollow plant stalk is made into the high polymer material with toughness and hardness, and the straw is acquired and made of the plant stalk and sticky rice. The production method has the advantages that green and zero-pollution effect and environmental friendliness are realized; immediate contact with human mouth cavity causes no side effect; after utilization, the straw is prone to dissolving with green burning; the production method is easy to operate and low in cost.

Description

technical field

[0001] The invention relates to a preparation method of straws, in particular to a preparation method of environment-friendly straws. Background technique

[0002] At present, it is widely known that most of the straws are made of plastic, and plastic is a main source of white pollution. Moreover, plastic straws are made of chemical raw materials, and various additives are added during the manufacturing process, which has certain toxic and side effects on the human body. The straw is directly in direct contact with people's oral cavity, which will have a certain impact on human health. Moreover, if you drink a hot drink with a straw, the plastic straw will also release toxic, harmful or carcinogenic substances, which will cause great harm to the human body. Plastic straws are not easy to decompose after use, and burning will produce a large amount of toxic and harmful gases, polluting the atmosphere. Moreover, some children like to bite the straw, which is...
