Problems solved by technology
[0002] In daily life, disposable water cups are widely used. Ordinary paper cups are a kind of paper container made by mechanically processing and bonding base paper (white cardboard) made of chemical wood pulp. Although it is easy to use and low in cost , but a large amount of wood will be consumed in the production process, which is not conducive to environmental protection; ordinary plastic cups contain non-degradable polystyrene, and after drinking, the cups are thrown away, which also makes this disposable plastic cup a The main source of "white pollution". At the same time, disposable water cups have no handles, which cannot solve the problem of scalding hands when filled with boiling water

Embodiment Construction
[0017] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
[0018] see figure 1 , an environmentally friendly water cup, including a cup body 1, the cup body 1 is composed of a first base layer 11, a second base layer 12, an inner surface layer 14 placed on the inner surface of the first base layer 11, and an outer surface layer 15 placed on the outer surface of the second base layer 12 And be placed in the center layer 13 composition between the first base layer 11 and the second base layer 12, the first substrate layer 11, the second base layer 12 are all bamboo fiber layers, 14 layers of inner surfaces are chitosan layers, the center layer 13 It is a PS foam layer, and the outer surface layer 15 is a polyhydroxyalkanoate layer.
[0019] Further, the thickness of the chitosan layer is 0.1-0.2mm, the thickness of the bamboo fiber layer is 0.4-0.6mm, and the thickness of the PS foam layer and the polyhydroxyalka...

Abstract
The invention discloses an environment-friendly water cup comprising a cup body. The cup body is composed of a first base layer, a second base layer, an inner surface layer, an outer surface layer and a center layer. The first and second base layers are bamboo fiber layers; the inner surface layer is a chitosan layer; the center layer is a PS foaming layer; and the outer surface layer is a polyhydroxyalkanoate layer. The beneficial effects of the water cup are that the cup body comprises the two bamboo fiber layers, and the PS foaming layer is arranged between the bamboo fiber layers, so that the strength of the cup body is greatly enhanced; the chitosan layer serves as the inner surface layer, so that the cup body is advantaged by stable performance, non-toxicity and tastelessness; the polyhydroxyalkanoate layer serves as the outer surface layer, so that the cup body is degradable; and the cup body is also provided with an outer cover capable of holding the cup body and the outer cover is provided with a handle on the side edge, so that a problem that the cup is hot is solved.
Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to an environmental protection water cup. Background technique [0002] In daily life, disposable water cups are widely used. Ordinary paper cups are a kind of paper container made by mechanically processing and bonding base paper (white cardboard) made of chemical wood pulp. Although it is easy to use and low in cost , but a large amount of wood will be consumed in the production process, which is not conducive to environmental protection; ordinary plastic cups contain non-degradable polystyrene, and after drinking, the cups are thrown away, which also makes this disposable plastic cup a The main source of "white pollution". At the same time, disposable water cups have no handles, which cannot solve the problem of scalding hands when filled with boiling water. Contents of the invention [0003] In order to solve the above problems, the invention provides an envi...
