Paper coated with silicon, vessel using the same and manufacturing method thereof

Abstract

Disclosed herein is a method of manufacturing a silicon-coated paper vessel, including the steps of: (a) providing liquid silicon and toluene; (b) mixing the liquid silicon and the toluene at a predetermined weight ratio to prepare a mixed solution; (c) applying the mixed solution on paper and then heating and curing the applied mixed solution to form paper coated with the mixed solution; and (d) forming the paper coated with the mixed solution into a paper vessel. The silicon-coated paper vessel manufactured using the method is advantageous in that the silicon- coated paper vessel is not harmful to the human body and exhibits high food storage capacity and high chemical stability. Further, the method is advantageous in that the silicon-coated paper vessel can be easily manufactured by pressing the silicon-coated paper using a die assembly or by adhering the silicon-coated paper to non silicon-coated paper.

Description

technical field [0001] The present invention relates to a paper container which is harmless to the human body, in particular to a silicon-coated paper coated with silicon, which is harmless to the human body and improves food safety storage, a silicon-coated paper container and a manufacturing method thereof. Background technique [0002] In modern social life, while the activity time, moving distance and information to be learned increase, it is necessary to maximize the effective use of limited time. [0003] The ingestion of food that provides energy is indispensable in human activities, and in the busy modern social life, it is necessary to ingest the required food quickly and easily within a limited time. [0004] In addition, in modern life, with the improvement of science and technology, living standards and cultural quality, and the trend of pursuing convenience, the use of disposable products has increased sharply. The development and use of beverage vending machine...

Problems solved by technology

[0010] However, the above-mentioned paper cups coated with polyethylene cannot be recycled due to the accumulation of polyethylene in the recycling process, and if they are incinerated, they will pollute the air due to the generation of smog, and even if they are landfilled, natural degradation will take hundreds of years time, thus becoming the cause of soil pollution

[0011] In addition, polyethylene emits environmental hormones according to the conditions of use, exposing users to carcinogens. Therefore, if used for a long time, it will cause toxicity and bring hidden dangers to food hygiene and stability.

[0012] In particular, it is estimated that if the above-mentioned polyethylene (PE) comes into contact with a high-temperature substance of about 100°C, PFOA (perfluorooctanoic acid) as an environmental hormone will be produced, causing a more serious problem, and an alternative substance is urgently needed.

[0013] As part of the improvement of the problems of the above-mentioned prior art, there is Korean Patent Registration No. 660980 (2006.12.18) "Environmentally friendly and recyclable food packaging water-soluble resin and paper containers utilizing the above-mentioned substances", which is to improve if used in The thickness of the paper of the container is less than 300 microns (μm), because the coated polyethylene cannot recycle or recycle the pulp, and can only be recycled when the thickness of the paper is greater than 350 microns, but the yield is less than 80%. Therefore, the technology of adding a slip agent and a dispersant to one or more water-soluble resins for coating

[0014] However, in the above-mentioned improved prior art, polypropionic acid emulsion, polyvinyl chloride, etc. are used in the coating process, silicon emulsion is used as a slip agent, and dioctyl sodium sulfosuccinate is used as a dispersant. The environmental protection aspect of recyclable pulp has not completely solved the problem of emitting environmental hormones and exposing users to carcinogens
