In the immersion step (S1) of the present invention, the fiber sludge and the waste paper are immersed for 2 to 5 minutes in a container containing a plasticizer.

At this time, the reason why the fiber sludge and waste paper are immersed in the barrel containing the plasticizer is to soften the properties of the fiber sludge and the waste paper so as to be easily mixed with each other.

The fiber sludge includes all of the sludge generated when processing the fiber as well as fiber sludge such as the residue generated when processing the fabric.

In addition, waste paper is recycled waste paper that is discarded can be economical effect by recycling the waste paper without discarding.

The first dehydration step (S2) is a step of dewatering twice with water to remove the fiber sludge and paper powder contained in the barrel after the immersion step (S1) to remove dust, impurities and plasticizers of the fiber sludge and waste paper.

The reason for dewatering the fiber sludge and the waste paper by using water is to remove the plasticizer on the immersion step (S1) and to remove the foreign substances such as the dust on the fiber sludge and the waste paper. .

The disinfection step (S3) is a step of disinfecting the dewatered fiber sludge and waste paper after the first dehydration step in a container containing a disinfecting solution mixed with naphthalene solution and water.

The reason for disinfecting the dewatered fiber sludge and waste paper is to remove odors such as odors discharged through the fiber sludge and waste paper during the immersion process (S1) and the first dehydration process (S2). Of course, this is to suppress the occurrence of bacteria such as fungi generated from fibrous sludge and lung paper.

At this time, the naphthalene solution is preferably used to dissolve naphthalene at 70 ℃ and the temperature of the water mixed with the naphthalene solution is preferably maintained at 23 ℃.

The secondary dehydration step (S4) is a step of dewatering the sterilized fiber sludge and waste paper three times after the disinfection step.

At this time, the dehydration frequency of the secondary dehydration process (S4) is not limited to three times, it is natural that the dehydration frequency can be four times as necessary.

The dewatering of the fiber sludge and the waste paper in the first dehydration step (S2) and the second dehydration step (S4) may be performed using a dehydration device in which dehydration is performed by rotation.

The aging step (S5) is a step of drying the dewatered fiber sludge and waste paper after the secondary dehydration process for 2 hours, sealing and aging for 5 days.

In this way, by aging the secondary sludge and the paper sludge dewatered by the aging step (S5) for 5 days it is possible to completely remove the moisture contained in the fiber sludge and paper powder.

The grinding step (S6) is a step of crushing the fibrous sludge and waste paper aged after the aging step into a grinder.

At this time, the method of pulverizing the fiber sludge and waste paper in the grinding step (S6) may be pulverized using a pulverizer, and the aged fiber sludge and waste paper may be put into a pulverizer and then pulverized.

The kneading step (S7) is a step of preparing a dough mixture by mixing the flame retardant solution to 19kg and 1kg of paper sludge powder pulverized after the grinding step and kneading the mixture.

At this time, the method of manufacturing the dough mixture in the kneading step (S7), the fiber sludge powder 19kg and paper powder 1kg may be put into a dough, such as a stirrer, and then put the flame retardant solution in the dough to prepare a dough mixture.

The flame retardant solution in which the powdered sludge powder 19kg and the paper powder 1kg are mixed in the kneading process (S7) is made by mixing 2kg polyethylene oxide, 2kg ammonium phosphate dibasic and 1.4kg water. Can be.

In this case, the dough mixture may be prepared by rotating the dough machine while spraying the flame retardant solution mixed with 2 kg polyethylene oxide, 2 kg ammonium phosphate dibasic, and 1.4 kg water for 20 minutes.

In addition, the flame retardant solution is a mixture of crushed fiber sludge powder 19kg and paper powder 1kg of the dough process (S7), 2kg phosphate ester (phosphoric ester), 1.5kg melamine cyanurate, 3kg edible preservative 3kg and water 8kg This can be done by mixing.

In this case, a flame retardant solution consisting of 2 kg of phosphoric ester, 1.5 kg of melamine cyanurate, 3 kg of edible preservatives, and 8 kg of water is added to the kneader with 19 kg of fiber sludge powder and 1 kg of paper powder. It is good to prepare a dough mixture by kneading by rotating for 2 hours.

In addition, the flame retardant solution is a mixture of crushed fiber sludge powder 19kg and paper powder 1kg of the dough step (S7), 3kg of water-soluble magnesium hydroxide (magnesium hydroxide) and 2kg of ammonium poly phosphinate (edible preservative) 3kg 5 kg of water may be mixed.

In this case, a flame retardant solution consisting of a mixture of 3 kg of water-soluble magnesium hydroxide, 2 kg of ammonium poly phosphinate, 3 kg of edible preservatives, and 5 kg of water was added together with 19 kg of fiber sludge powder and 1 kg of paper powder. After 1 hour by rotating the kneader to prepare a dough mixture.

Thus, the flame retardant solution is mixed in the kneading step (S7) to kneading the fiber sludge powder and paper powder to prepare a dough mixture can have a flame retardant by the flame retardant solution.

The drying step (S8) is a step of drying the kneaded dough mixture after the kneading step.

The drying step (S8) is to dry the flame retardant solution soaked completely into the fiber sludge powder and paper powder at room temperature for 1 day or the flame retardant solution is put into a drying chamber maintaining the temperature of 70 ℃ for 2 days Drying the fiber sludge powder and paper powder completely or drying the dough mixture for 2 hours. The drying method may be variously modified according to the flame retardant solution.

The said grain processing should just use a generally known fiber ball processing machine, and the detailed description is abbreviate | omitted.

At this time, the reason for limiting the diameter of the granules to 0.5mm-3mm is to facilitate the ejection of the granules by ejecting the granules through the molding machine in the heat insulating material processing step (S11) and extruding the granules. If it is less than mm, it is not easy to construct the insulation by the blown grains. If the diameter of the grain is 3mm or more, it is not easy to spray the grains, and the space between the grains is too large when the insulation is formed by the grains. It is to prevent the thermal insulation effect is lowered because it is formed large.

The material to be sprayed process (S10) is a process of mixing the material to be sprayed by mixing the processed granules and water 20kg, edible room member 3kg, waterproofing agent and synthetic resin solution 2kg.
