Manufacturing method of Nonflammable EPS sandwich pannel
The present invention relates to a method for manufacturing a nonflammable insulating sandwich panel, the method comprising: (a) an inorganic mixing process for preparing an inorganic powder liquid mixture in which 800-1,000 parts by weight of a spontaneously heated separate liquid mixture are mixed with 50-70 parts by weight of an inorganic powder prepared by mixing carbon powder and silica in equal amounts, heating and melting the mixture at 1,300-2,000°C, and cooling and pulverizing the mixture; (b) an expanded Styrofoam bead process for preparing expanding Styrofoam beads of 0.3 mm by 30-50 times to prepare expanded Styrofoam beads (EPS); (c) an expanded Styrofoam beads mixing process for mixing 120-150 parts by weight of the EPS with the heated inorganic powder liquid mixture; and (d) a sandwich panel process for pouring the EPS mixture into a mold to prepare expanded Styrofoam expanded through spontaneous heat, and manufacturing a sandwich panel using the expanded Styrofoam. In particular, the separate liquid mixture is prepared through the following steps: a base liquid step (a1) for mixing 100 parts by weight of water with 11-19 parts by weight of nitric acid, and gradually dropping therein 3-7 parts by weight of magnesium in small amounts as the mixture starts to boil and becomes clear, to complete a base liquid; a mixed liquid step (a2) for slowly stirring in a heating stirrer, 100 parts by weight of water, 14-21 parts by weight of sodium oxide, 45-56 parts by weight of silicon dioxide, 0.03-0.07 parts by weight of iron oxide, and 0.3-0.9 parts by weight of a dispersing agent; a stirring step (a3) for gradually dropping in the mixed liquid prepared in the mixed liquid step (a2), 1.6-5.2 parts by weight of magnesium carbonate and 4-9 parts by weight of the base liquid prepared in the base liquid step (a1), and stirring the same until steam is generated; and an addition step (a4) for adding 3-9 parts by weight of a water repellent to the stirred mixture, and stirring and heating the mixture until the mixture becomes clear.
