And can be widely used in the field of construction because it can be provided in a plate form.
BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows an extruder that can be used to produce sheet-like insulation according to one embodiment of the present invention.
Hereinafter, the present invention will be described in detail by way of examples. These examples are for further illustrating the present invention, and the scope of the present invention is not limited to these examples.
A method of manufacturing a heat insulating material using the water glass of the present invention comprises:
1) mixing water glass with TEOS and zirconium propoxide and stirring;
2) adding distilled water to the stirred mixture and reacting at a temperature of 100 to 150 ° C with stirring;
3) cooling the reactant to obtain a water-resistant waterglass;
4) mixing the water-resistant water-glass and cellulose; And
5) adding titanium oxide to the mixture and mixing.
According to an embodiment of the present invention, the above materials are mixed with water glass: zirconium propoxide in a ratio of 25: 1: 1 Ratio. ≪ / RTI > The TEOS and zirconium propoxide serve to impart water resistance to water glass by replacing silicon contained in water glass with zirconium. The mixing ratio is sufficient to ensure the water resistance of the water glass. In one embodiment of the present invention, the mixture is agitated at about 300 rpm using a stirrer. At this time, the water glass is dispersed at first, and after about 15 seconds, it is solidified into one lump. After about 10 minutes, the hardened mass starts to loosen a little, and the lump is cracked with a wooden stick and released, and it is stirred again.
According to an embodiment of the present invention, distilled water corresponding to about 6% by weight of water glass is added to the completely dissolved mixture, and the mixture is stirred in an autoclave at 150 ° C for about 24 hours Respectively. In this process, the silicon (Si) in the water glass is replaced with zirconium (Zr) and the water glass becomes water resistant. The reason why water glass has water resistance is that hydrolysis is difficult when the silicon in water glass is replaced with zirconium.
The step 3) is a step of obtaining the water-resistant water glass produced in step 2). According to an embodiment of the present invention, when the mixture reacted for 24 hours as described above is cooled and water glass is taken out from the reaction flask It is desirable to seal the entrance with wax paper. This is because the surface of the water glass in the flask can be prevented from being dried to form a film. At this time, when the film is formed by surface drying, the membrane also has water resistance, so it does not melt into the water glass.
In step 4), cellulose is mixed with the water-resistant water glass obtained in step 3). The reason for mixing cellulose is to prevent cracks on the surface during drying of the water glass sol, foaming process, it is necessary to prevent the bubbles from becoming larger than necessary. In one embodiment of the present invention, the mixing ratio of the cellulose and the water-resistant water glass may be 1:40 by weight of the cellulose: water-resistant water glass. Specifically, the cellulose may be put into a mixer and operated. Then, the water-resistant water glass prepared in the step 3) is added and the mixer is operated until the cellulose is sufficiently dispersed.
The step 5) is a step of mixing titanium oxide with the mixture of step 4). The reason for mixing titanium oxide is that when water is mixed with other oxides, the water glass sol tends to harden with the lapse of time, And in particular to utilize the antimicrobial properties of titanium oxide in this process. In one embodiment of the present invention, it is preferable that the titanium oxide is mixed in an amount such that the weight ratio of the water-resistant water glass used in the step 4) to the titanium oxide: water-resistant water glass is 1: 5. Titanium oxide is added to the mixture and mixed until thoroughly mixed. When the titanium oxide is fully dispersed, it is put in a plastic container and sealed so that moisture does not evaporate.
Further, in the method of the present invention, in order to produce plate-
6) mixing the titanium oxide-added mixture obtained in the step 5) with soda and rapidly mixing the mixture in 10 seconds or less; And
7) The step of introducing the soda-added mixture into a roller in an extruder maintained at a temperature of 100 to 150 ° C.
In accordance with one embodiment of the present invention, an extruder that can be used in steps 6) and 7) is shown in FIG. 30% by weight of soda was added to the heat insulating material completed in the step 5), and the mixture was quickly mixed through the extruder within 10 seconds. Then, the mixture was placed between the thick paper as shown in FIG. 1, When the temperature of the roller is maintained at about 120 ° C., foaming occurs due to the generation of carbon dioxide. As a result, a plate-shaped heat insulating material having porosity and being insoluble in water and being incombustible is produced. If this insulation board is cut to the proper size, it can be used as general building insulation.
