Description

Manufacturing method for Biodegradable Starch Resin vessel

The present invention relates to a method for producing a biodegradable container, and more particularly, by mixing biodegradable fillers, adhesives, lubricants and polishes with powders containing biodegradable cellulose, and compression molding under high temperature and high pressure to prepare containers after use. The present invention relates to a method for producing a biodegradable container so that it is easily decomposed naturally.

Conventionally, containers made of synthetic resin, such as styropol, are mainly used for packaging, but such synthetic resin containers are not only harmful to the user's health because chemicals harmful to the human body are used in the manufacturing process, and these containers are mainly used for disposable use. After being easily discarded, the discarded container thus causes environmental pollution because it is hardly decomposed, and when incinerated, dioxins, which are carcinogens, have a problem that adversely affects health.

In order to reduce such a problem, a container in which straw is added to synthetic resin has been manufactured recently, but since synthetic resin is still included in this container, environmental pollution and adverse effects on the human body will be somewhat reduced compared to a container composed of conventional synthetic resin. The problems of environmental pollution and deterioration due to the use of packaging containers could not be completely solved.

An object of the present invention for solving the problems as described above is to prepare a container by compression molding under high temperature and high pressure by mixing biodegradable filler and adhesive powder and lubricant and polish powder in powder containing biodegradable fiber, It is to provide a method for producing a biodegradable container that does not cause environmental pollution by causing the natural degradation easily and cause a user's deterioration of health.

1 is a process chart showing a method for producing a biodegradable container according to the present invention.

An embodiment of the present invention for achieving the above object will be described in more detail below.

The method for producing a biodegradable container according to the present invention is 60-80% by weight of powder containing fiber passed through 60 mesh sieve, 5-15% by weight corn starch passed through 60 mesh sieve as a filler, 60 mesh sieve as a binder. 10-20% by weight of wakame powder passed through, 1-5% by weight of Ca (C ₁₇ H ₃₅ C ₉ ) ₂ Ca and _3-5 % by weight of CaCO _{3 with a} polishing agent, and then inserted into the mold 110-180 ℃ The container was molded by compression molding at 10-45 mpa / cm for 15-45 seconds, and the molded container was dried and disinfected.

On the other hand, the filler and the binder serves to make the components constituting the container well mixed, the lubricant is to be easily separated from the mold when the mold is put in the mold, the gloss to make the product itself glossy.

In addition, the powder containing fiber is selected from straw, rice straw, peanut peel, buckwheat husk, corn stalk, ocher, charcoal, ginseng leaf, green tea leaf, pine needles or two or more of these mixed and used.

One embodiment of a biodegradable container according to the present invention configured as described above will be described with reference to the accompanying drawings.

1 is a process chart showing a method for producing a biodegradable container according to the present invention.

Grinding process

Choose from two or more straws, rice straws, peanut shells, buckwheat husks, or cornstalks, or mix and dry the optional fibrous material among them, pass through a 60 mesh sieve, and pass 70% by weight of the fiber to the total weight. Prepare the powder containing.

Then, the dried corn starch is pulverized and passed through a 60 mesh sieve to prepare 10% of the total weight.

In addition, after grinding the dried seaweed to prepare a 15% to the total weight by passing through a 60 mesh sieve.

Stirring process

(C ₁₇ H ₃₅ C ₉ ) ₂ Ca 3% and CaCO ₃ 2% are mixed with 70% by weight of the powder containing fiber as described above, 10% by weight of corn starch, and 15% by weight of dry seaweed powder.

Molding process

Then, the mixture is inserted into a mold and then compression-molded at 110-180 ° C. and 10-45 mpa / cm for 15-45 seconds to form a container.

Drying and Sterilization Process

As described above, by drying the container subjected to the coating process, drying and disinfection are performed at the same time.

Printing process

As described above, a predetermined pattern or text is printed on the surface of the container which has been dried and sterilized.

According to the present invention as described above all the components constituting the packaging container is biodegradable, even if discarded after use there is an effect that does not easily cause environmental pollution.

In addition, it does not contain harmful chemical components to the human body, and does not generate harmful substances such as dioxin even during incineration, so there is an effect that does not harm the health of the user even after the use of the container and the use of the container.

Claims (1)

In the manufacturing method of the packaging container, 60-80 wt% of powder containing fiber passed through 60 mesh sieve, 5-15 wt% of corn starch passed through 60 mesh sieve as filler, 10-20 wt% of seaweed powder passed through 60 mesh sieve as binder, lubricant 1-5% by weight of CaCO _{3 and} 1-5% by weight of CaCO _{3 with a} polishing agent, and then inserted into a mold and compression molded for 15-45 seconds at 10-45mpa / cm at 110-180 ° C to form a container. And drying and disinfecting the molded container.
