Description

Method of manufacturing high strength sheet using paper {Method of manufacturing a solid board utilizing paper}

The present invention relates to a high-strength sheet manufacturing method using paper, and more particularly, to a high-strength sheet manufacturing method using paper that can be utilized as a new environmental protection packaging material because of the high strength and low consumption of materials.

In general, in order to package expensive articles or fragile articles such as glass articles, development of a packaging box made of a hard and shock-absorbing material has been continuously required.

In order to meet these demands, the corrugated boards, which are configured to be folded or cut out in a form of styrofoam or a predetermined form, are fixed to the inside of the packaging box.

In addition, in the case of a package having a heavy weight, such as a refrigerator, wooden pallets are widely used because of the cushioning against external impact and durability to support the weight with sufficient force.

In recent years, as well as the difficulty of supplying raw materials and the recycling and recycling movement using waste resources in an effort to protect the environment, waste resources that are discarded instead of expensive natural pulp or wood, which are almost entirely dependent on imports Although the strength decreases somewhat by using, the corrugated material having durability and cushioning at the same time is used in various forms in various fields.

However, such a conventional corrugated material maintains excellent buffering properties and stable strength, but not only very weak to the perforation strength, but also because the strength is below a certain level, there was a problem that it is difficult to apply to a heavy article.

In addition, various materials made of paper have a problem in that the strength is easily lost and the function is lost in long-term use or a place where there is a little moisture due to excellent water absorption.

Therefore, the main object of the present invention is to provide a high-strength paper sheet to be used for high-weight articles and the like, and to utilize not only waste paper, but also to recycle, to provide a high-strength sheet manufacturing method using environmentally friendly paper.

Another object of the present invention to provide a high-strength plate manufacturing method using a light and easy to use paper.

Another object of the present invention is to provide a method for producing a high strength plate using paper that can be used safely in places where moisture or moisture is not only extended to the life of the high strength plate by inhibiting the penetration of moisture.

In order to achieve the above object, a high-strength sheet manufacturing method using the paper of the present invention, the adhesive manufacturing process, the honeycomb-shaped honeycomb manufacturing process, and the honeycomb manufacturing process Before, after, the left, right, upper and lower surfaces by using a step of attaching a sheet of paper using the adhesive as a basic feature of the technical configuration.

When described in detail with reference to the accompanying drawings a preferred embodiment of the present invention configured as described above are as follows.

1 is a process chart showing a high-strength plate manufacturing method using a paper according to the present invention, Figure 2 is a perspective view showing the decomposition of the plate produced by the high-strength plate manufacturing method using a paper according to the present invention.

As shown in Figures 1 and 2, the method of manufacturing a high strength sheet using paper of the present invention is 17.9% corn starch, the main adhesive, 80.2% water, sodium oxide 1.4% neutralizing agent, boron 0.4% having a coating function and coagulant Adding 0.1% of phosphorus magnesium chlorate to a stirrer and mixing the mixture to produce an adhesive mixture, manufacturing a honeycomb-shaped inner core 110 using the adhesive mixture, and manufacturing the inner core 110. In the unfolded state before, after, left, right, up and down, using the adhesive mixture of the cotton paper 120, and the step of drying using a microwave pressurized and cut to a certain standard.

The adhesive mixture generation step is preferably produced by stirring evenly for 30 to 70 minutes at room temperature of 5 ℃ or more.

The centrifugal force of the stirrer is ideally about 600 kg.

In the manufacturing step of the inner core 110, the base paper 111 is pressed and compressed in a state in which several layers are wound, and then cut into a predetermined thickness and applied by gluing by applying an adhesive mixture to the shape mutually attached portions of the honeycomb, and the attachment is completed When this occurs, honeycomb-shaped honeycomb is formed.

Here, the base paper 111 of the inner core 110 uses a high-strength paper made of 180 g of paper per square meter.

Attaching the cotton paper 120 to the inner core 110 made of a honeycomb shape is attached to the cotton paper 120 using an adhesive mixture on the upper and lower surfaces of the inner core 110 spread in a honeycomb shape and dried Let's do it.

Drying is dried in the microwave oven, the condition is preferably to dry the cotton paper 120 attached to the inner core 110 by maintaining the temperature from 18 ℃ to 22 ℃ and the humidity fixed from 60% to 70%. .

In addition, after attaching the cotton paper 120 to the inner core 110 may be laminated sequentially to naturally dry.

In this case, it is preferable that the pressing plate or the like is placed on the upper surface of the top surface paper 120 and dried.

Here, the paper 120 is preferably used to use a cardboard of 360g reinforcement paper in 1㎡, the thickness of the minimum.

When the drying of the inner core 110 and the cotton paper 120 is completed, the high strength plate 100 of a predetermined size is completed by cutting the left and right sides before and after.

On the other hand, the front letter of the high-strength sheet material 100 cut off before, after, left and right may be formed by selectively attaching the sheet of paper 120 to the front, rear, left and right as desired or necessary.

Referring to the operation of the present invention as follows.

First, 17.9% of corn starch, the main raw material, 80.2% of water, 1.4% of sodium oxide, neutralizing agent, 0.4% of boron having a coating function, and 0.1% of magnesium chlorate, a coagulant, were added to the stirrer and mixed to form an adhesive mixture. As well as excellent adhesive strength of the adhesive mixture by inhibiting the penetration of moisture into the interior of the paper to prolong the life of the high-strength plate 100 and to be quickly and firmly bonded.

In addition, the base paper 111 of the inner core 110 forms a honeycomb honeycomb using high-strength paper made of 180 g of paper at 1 m 2, and the cotton paper 120 is made of 360 g of reinforced paper at 1 m 2. By using cardboard and improving the strength of the adhesive mixture, the strength of the high strength plate 100 can be further improved.

In addition, since it is made of paper, there is no fear of environmental pollution, and it can be produced as waste paper and has excellent recyclability.

As described above, the high-strength sheet manufacturing method using the paper of the present invention is 17.9% corn starch as the main adhesive, 80.2% water, sodium oxide 1.4% neutralizing agent, 0.4% boron having a coating function and magnesium chlorate 0.1 as a coagulant Injecting the% in a stirrer and evenly mixed to produce an adhesive mixture, to produce a honeycomb-shaped inner core 110 using the adhesive mixture, and in the state that the prepared inner core 110 is unfolded And, after, using the adhesive mixture of the cotton paper 120 on the left, right, top, bottom, and the step of drying using a microwave pressurized and cut to a certain size, so it can also be used for heavy articles It can be recycled using waste paper, and there is no fear of environmental pollution, and it can minimize the weight.
