Characteristics and effects of the rice bran, the sugar beet, the glutinous rice, the zeolite and the wood vinegar used in the method of manufacturing the adhesive composition of the corrugated cardboard according to the present invention will be briefly described below.

First, rice bran is called rice gruel and rice bran when it is roasted from brown rice to rice gruel. That is, it is called rice gruel which rice husk which is crusted out of rice husk is ripped out, and rice husk (rice bran) It is called white rice (white rice).

In rice gruel and rice bran, which are peeled off from brown rice to white rice, 90% to 95% of total nutrients of rice are contained in rice bran and rice gruel. It is because it is a lot of contents.

At present, rice husk is a by-product produced in the process of stripping rice husks and making rice. It is mainly used as feed for livestock and used for some cleansing and nourishing supplements. As the beneficial ingredients contained in the rice are scientifically identified Since then, the US Steel has been expanding its applications to such a wide extent that it can be applied to a wide range of industrial fields such as cosmetics, food, and pharmaceuticals.

It has been proved that it has excellent efficacy such as iron calcium, magnesium, sodium, vitamin E and the like to maintain the homeostasis of the human body, to prevent aging of tocopherol and the like, and to treat wrinkles and spots freckles acne.

It is called "wrapped rice" because it is called "broken rice". Half-crushed rice is poor in quality as rice, so it is rare to eat rice and it is widely used as rice cake, alcohol, processed livestock feed, and so on.

Zeolite is a kind of hydrated aluminum silicate minerals containing alkali metal or alkaline earth metal, which is a minerals obtained from volcanic rocks. It is a structure in which tetrahedrons of (Si, Al) O4 are bonded in a cubic network. , It is possible to adsorb a large amount of water at the same time with the function of molecular sieve by the gaps, and the pore shape is maintained even at a high temperature, and ammonia, heavy metals and toxic substances It is adsorbed and becomes saturated and does not discharge again, and is used as a filter medium formed of soft water.

The structural features of zeolite are the ability to selectively adsorb unsaturated hydrocarbons or polar substances by the action of cations in the crystal structure, and they have a constant pore size, , And the separation of n-paraffin and isoparaffin, ortho, meta and para isomers can be separated by using the molecular sieve effect.

In addition, since it contains exchangeable cations in the crystal structure, it can easily exchange ions with other cations freely. By using this property, it is possible to remove harmful substances, concentrate and recover useful components.

Wood vinegar is called phytoncide and has anti-bacterial antiviral function and toxic neutralizing function from pesticides and chemicals. It is effective for skin diseases such as atopy and is also used as a fragrance. .

Accordingly, it is an object of the present invention to provide an adhesive composition which is prepared by mixing rice bran, sugar beet, glutinous rice, zeolite, wood vinegar and water, and kneading and heating the same to use as an adhesive for corrugated cardboard.

Hereinafter, a procedure for manufacturing an adhesive composition for corrugated cardboard containing rice bran and zeolite according to the present invention will be described in detail with reference to FIG.

1. Material preparation process

15 to 30% by weight of rice bran, 10 to 20% by weight of rice straw, 7 to 15% by weight of glutinous rice, 5 to 10% by weight of zeolite, 3 to 8% by weight of wood vinegar and 30 to 40% Prepare the material.

The zeolite in the form of natural minerals is put into a crusher and crushed into particles of 5 mm or less. Then, the particles are sorted to remove impurities. More specifically, the crushed mineral particles of zeolite are put into a thermal kiln and then heat is applied at a temperature of 800 to 900 占 폚 to completely remove water and impurities, and then the mixture is pulverized into fine particles, A zeolite powder in a fine powder state is prepared by filtering with a sieve having a particle size.

2. Primary mixing process

  15 to 30% by weight of rice bran, 10 to 20% by weight of rice straw, 7 to 15% by weight of glutinous rice, 5 to 10% by weight of zeolite and 30 to 40% by weight of water are mixed and kneaded at high speed. The mixture formed by stirring the rice bran, sugar beet, glutinous rice, zeolite, and water is activated as an adhesive component by reacting rice bran, wrapper and glutinous rice with water.

3. Heating process

In the heating step, the mixture is rapidly rotated in an agitator to rapidly cool the mixture of kneaded rice bran, sugar beet, glutinous rice, and zeolite by heating at 100 ° C or less for a certain period of time.

The heating and rapid cooling at 100 ° C or below is intended to prevent the microorganisms contained in the zeolite from being killed, and the cooling treatment improves the adhesion of the mixture.

That is, the mixture of rice bran, rice wine and glutinous rice reacts with water by the stirring process and the glue and glutinous rice react with water to generate the adhesive component, and the adhesive force is maintained by the rapid cooling process.

Since the zeolite powder has a large particle size, zeolite micropores can be easily adhered to the zeolite zeolite zeolite by mixing with rice gypsum and silage, so that the zeolite zeolite zeolite zeolite zeolite zeolite zeolite zeolite zeolite zeolite zeolite zeolite zeolite zeolite zeolite zeolite zeolite zeolite zeolite

4. Secondary mixing process

 The mixture is mixed with 3 to 8 wt% of wood vinegar by mixing with the mixture formed by the primary mixing step, and then the mixture is heated at 80 ° C or less for a predetermined time and cooled at room temperature.

The adhesive component formed by the above forms an eco-friendly adhesive containing the adsorption effect of the residual pesticide upon the adsorption of zeolite and the toxic neutralizing function of the throat solution.

The corrugated cardboard sheet according to another embodiment of the present invention will be described with reference to FIG. 4. Referring to FIG. 4, the corrugated cardboard sheet 15 to 30% by weight, 10 to 20% by weight of sugarcane, 7 to 15% by weight of glutinous rice, 5 to 10% by weight of zeolite and 30 to 40% by weight of water are mixed and kneaded at high speed to rapidly quench the mixture. And then cooled at room temperature to produce an adhesive 100 (step S100)

The adhesive 100 prepared as described above is evenly applied to the upper carton 200 and the lower carton 210 or the corrugated paper 220 of the cardboard.

Then, in step S200, a super absorbent polymer (SAP) 400 called polymer is applied to the upper or lower paperboard 200 or the lower paperboard 210 (step S300)

The superabsorbent polymer (SAP) is a polymer that absorbs water several tens to hundreds of times its own weight. Since the material itself absorbs water, it absorbs more water than cotton or cottonseed. It is most commonly used for diapers for infants, adults, and animals because it does not emit water.

Meanwhile, the SAP 400 may be applied to the upper and lower paperboards 200 and 210, respectively, depending on the use of the paperboard.

In the case of corrugated cardboard manufactured through the superabsorbent resin (400), the adhesive component of the adhesive (100) can be maintained by absorbing moisture when exposed to moisture, and the corrugated cardboard can be protected by absorbing external moisture.

The corrugated paper sheet 220 is bonded between the upper and lower paperboards 200 and 210 to which the adhesive 100 is applied and is passed between the bonding rollers 300 to bond the corrugated paperboard. (Step S400)

On the other hand, the material of the corrugated paperboard according to the present invention may be any one of EVA resin, paraffin wax, melamine phosphate, sodium silicate, carbon nanotube, starch, carboxymethylcellulose, stearic acid, clay, potassium oxide, titanium dioxide, iron oxide, , The mixture is conveyed to an impregnation tank, and the liner and corrugated paper are dried at a speed of 100 to 150 m / min through an impregnation tank to prepare a corrugated paperboard.

The properties of the corrugated paperboard of the present invention are as follows: EVA resin is an environmentally friendly aqueous emulsion type resin having good water resistance, unique elasticity, excellent adhesion to corrugated paper, and paraffin wax having excellent water repellency There are characteristics.

The above-mentioned melamine phosphate is a compound of melamine and phosphorus having a high content of nitrogen, and is an environmentally friendly flame retardant which does not contain formalin at all, unlike a melamine resin, and enhances the tensile strength of corrugated paper. Sodium silicate, called "water glass", acts to strengthen the role of flame retardant and tensile strength of corrugated cardboard.

The carbon nanotube serves as a flame retardant filler and acts to enhance flame retardance by combining with melamine phosphate, sodium silicate and clay. Starch is a low viscosity starch, It improves the strength of the paper and enhances the adhesion between the liner (Liner) and the corrugated paper (Medium paper).

Carboxy methyl cellulose acts as reinforcement of clay together with clay. Clay (clay) is an earth power reinforcing agent, and is a mixture of silicon oxide, aluminum oxide, iron oxide, magnesium oxide, and the like.

On the other hand, potassium oxide (K ₂ O), titanium dioxide (TiO ² ), iron oxide (Fe ₂ O ³ ) and the like serve to strengthen and maintain bonding between the respective components of the clay, and the amino binder As a binder exhibiting its function, it serves to stabilize binding with melamine phosphate, and at the same time, exhibits a function of strengthening the tensile strength of paper.

In addition, the mixing ratio of each of the mixed components of the composition may be adjusted according to the use of the finished corrugated cardboard or corrugated cardboard laminate board. It is possible to control the amount of the melamine phosphate and the amino binder which determine the strength and the durability of the composition or to adjust the amount of the mineral raw material including the clay to select the mixing ratio suitable for the strength of use.

Accordingly, the composition for corrugated cardboard of the present invention comprises 10 to 20 wt% of ethylene vinyl acetate (EVA) resin, 10 to 20 wt% of paraffin wax, 5 to 10 wt% of starch, 0.1 to 0.3 wt% of carboxymethyl cellulose, 0.1 to 0.3 wt% of stearic acid, 1 to 10 wt% of clay (clay), 5 to 10 wt% of potassium oxide, 1 to 5 wt% of titanium dioxide, 1 to 2 wt% of iron oxide and 40 to 60 wt% of water .

According to the above-described constitution, the process for producing the corrugated paperboard of the present invention is as follows. First, water, EVA resin and paraffin wax are added to a mixer and stirred slowly for 30 minutes. Carboxymethylcellulose is then added in small amounts for 30 minutes, , Starch is added 4 to 5 times, and mixing is continued for 120 minutes.

Then, water and stearic acid are added to the mixer and dissolved for 60 minutes, melamine phosphate is added and dispersed for 30 minutes. Then, the clay, potassium oxide, titanium dioxide and iron dioxide are added and dispersed in order, and finally the amino binder is added, followed by stirring for 2 hours to carry out secondary mixing.

After completion of the secondary mixing, the primary mixture is dropped into the secondary mixer from the primary mixer for 40 to 50 minutes before impregnation, and further mixed for 20 to 30 minutes after completion, thereby completing the mixing of the corrugated cardboard material. The corrugated paper is dried at a speed of 100 to 150 m / min through the impregnation tank, and the corrugated paperboard is produced.
