Thermal insulation and degradable ceramic lunch box and preparation method

Abstract

The invention discloses a method for preparing a thermal insulation and degradable pottery lunch box. The raw materials include pottery clay, bamboo fiber, chitosan, glycerin, sodium alginate, adhesive, oil-proof agent and water-repellent agent. The lunch box is divided into Two-layer structure, the inner layer is a ceramic layer, and the outer layer is a degradable fiber layer; the outer layer of the present invention is a degradable fiber layer. After a period of time, the outer layer is degraded, which greatly reduces the pollution to the environment; the inner layer It is a ceramic layer. After the ceramic layer is discarded, it will still be soil after weathering and decomposition; it is not easy to break, light in weight, safe and environmentally friendly, good in heat preservation, simple in production process, low in cost, and good in economic and social benefits.

Description

technical field [0001] The invention relates to the field of lunch boxes, in particular to a thermal insulation and degradable ceramic lunch box and a preparation method. Background technique [0002] Since the first appearance of plastic products in the early 20th century, people's lives have undergone major changes. The most obvious manifestation of this change is that it has brought great convenience to our daily life. With the rapid development of economy and technology, people's living standards continue to improve, and the pace of life continues to accelerate, so the fast and convenient fast food industry has developed rapidly. Nowadays, people gradually realize that the plastic products that once brought us great convenience are also eroding our living space, the land becomes barren, marine life is poisoned, and the balance of the biological chain is broken. Disposable fast food boxes commonly used at present, because their materials are not degradable, and certain c...

Problems solved by technology

Disposable fast food boxes commonly used at present, because their materials are not degradable, and certain chemical components harmful to human body are added in the process of processing and molding, such fast food boxes cannot be heated, and not only cause great pollution to the environment, but also The human body causes certain damage, which is neither environmentally friendly nor healthy, so it also seriously restricts the development of the fast food industry

Although biodegradable materials are getting more and more attention, it will still take a long time to completely replace some disposable lunch boxes

[0003] Not all disposable lunch boxes on the market today meet the national standards. Long-term use of unqualified lunch boxes will have adverse effects on the body
