Problems solved by technology

[0002] At present, the paper cups on the market are only single-layer, which cannot provide the effect of heat preservation and heat insulation. If it is folded and formed in multiple layers, the paper material used will be more than doubled, which will lead to deforestation, which will greatly consume environmental resources and cost. also extremely high
[0003] Moreover, the heat-proof containers on the market are all used by adding plastic cups, but it is also extremely inconvenient to use. Generally, plastics are not easy to degrade and cause great harm to the environment.

Embodiment 1

[0029] Embodiment 1: as figure 1 -Shown in 3, a method for preparing a paper / plastic container with a thermal insulation surface layer is characterized in that, comprising the following steps:

[0030] a. Brush the composite foam coating on the outer surface of the material used to make the container 1 (thus forming the coating layer 2). The composite foam coating is applied on the material by means of rotation, spraying, printing, etc., and preferably The other is to paint on the part where the user may hold the container 1, so as to achieve the purpose of saving materials without affecting the use effect;

[0031] b. The material processed in the previous step is made into a container, and the cup-making machinery used is available in the market;

[0032] c. The prepared container 1 is heated again, so that the foaming coating on the outer layer of the container 1 is heated and foamed (forming such as image 3 The bulging microbubbles are shown in 3). During the heat...

Embodiment 2

[0039] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that in step a, patterns or characters are first printed on the outer surface of the material, and then the composite foaming paint is applied on the outer surface of the material.

Embodiment 3

[0040] Embodiment 3: This embodiment is basically the same as Embodiment 1, except that in step a, after the composite foam coating is applied on the outer layer of the material, patterns or characters are printed on the outer layer of the material.

Abstract

The invention provides a manufacturing method of a paper / plastic container with a heat insulation surface layer. The manufacturing method comprises the following steps of: (a) brushing a composite foaming coating on an outer surface layer of a material for manufacturing the container; (b) manufacturing the container by the material after processing in the last step; and (c) further heating the manufactured container, and heating the foaming coating on the outer surface layer of the container for foaming. According to the manufacturing method disclosed by the invention, the composite foaming coating containing microsphere foaming particles is brushed on the outer surface layer of the container, and when the container is heated, the foaming effect of the microsphere foaming particles is utilized, and a foaming layer is formed at a hand-holding part on the surface of the container, so that the effects of increasing thickness, realizing heat preservation and heat insulation, preventing slippage and preventing water condensation can be realized and resources can be greatly saved.

Description

technical field [0001] The invention relates to a method for making a disposable container, in particular to a method for making a paper / plastic container with a heat-insulating surface layer. Background technique [0002] At present, the paper cups on the market are only single-layer, which cannot provide the effect of heat preservation and heat insulation. If it is folded and formed in multiple layers, the paper material used will be more than doubled, which will lead to deforestation, which will greatly consume environmental resources and cost. Also extremely high. [0003] Moreover, the heat-proof containers on the market are all used by adding plastic cups, but it is also extremely inconvenient to use. Generally, plastics are not easy to degrade and cause great harm to the environment. Contents of the invention [0004] In order to overcome the above-mentioned deficiencies existing in the prior art, the object of the present invention is to provide a method for maki...
