BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

As shown in Figures 1 to 8, the manufacturing method of the winter clothes using the vacuum panel insulation of the present invention is silicon dioxide (SiO 2) 70%, aluminum oxide (Al 2 O 3) 13%, calcium oxide (CaO) 17% powder per unit weight To prepare a silica powder 12 by mixing.

Thus, the silica powder 12 is melted by heating to a temperature in the range of 1000 ~ 1500 ℃ using the heater 13 in the melting mold 10.

In addition, the silica powder 12 has microporosity, low density to minimize thermal conductivity, billions of nano-pockets to prevent heat transfer, heat energy reflection to reflect heat like a mirror, and a lightweight solid structure. As the powder, it is made to improve the thermal insulation by increasing the degree of vacuum of the vacuum insulation material and to give a deformation of the shape of the uneven part, the bent part or the stepped part in the appearance during panel molding.

In addition, since the silica powder 12 is harmless to humans and is nonflammable, it is very advantageous to be used as a building insulation material or a refrigerator insulation material, and has excellent moldability and low cost compared to glass fiber, urethane foam, and styrofoam used as a conventional insulation core material. It is very advantageous to be used as insulation core material

At this time, the melting mold 10 is formed in the form of a funnel as a whole, the melt is dropped to a small capacity to form a stream of water through the funnel (11).

Here, when the molten liquid falls through the funnel (11), oxygen is injected into the molten liquid falling at high pressure.

As a result, the molten liquid is formed in the form of a plate in the form of a plate by a pressure roller 30 which sucks and collects rod-shaped fine particles scattered by oxygen injected at a high pressure into the mold 20.

At this time, the fine particles are in the form of a cylindrical rod, the diameter is 3μ or less, the length is produced to 200u or less.

Here, the mold 20 has a large area of the inlet 21 through which the fine particles flow, and the narrower the area is formed as the square portion is formed in the shape of a rectangular cylinder 22 as it proceeds backward.

In addition, a plurality of blower holes 21a penetrate the inlet portion 21 along the width direction so as to induce the inflow of fine particles when the suction force of the blower is applied.

In addition, the pressure roller 30 is configured to pressurize the particulates collected through the open space 23 formed in the upper and lower left and right sides of the molding die 20 while rotating the upper and lower left and right sides.

In this case, the open space 23 is generated at a position capable of partitioning the inlet portion 21 and the molding portion 22, and the inlet portion 21 and the molding portion 22 are as much as the open space 23. It is installed spaced apart.

On the other hand, the completed core material 40 is moved to the conveyor belt (22a) located at the bottom while exposed through the molding portion 22 of the molding die 20, to the rear of the conveyor belt (22a) The cutter 22b which cuts the core material 40 to a fixed size is provided.

That is, by cutting the core material 40 with the cutter 22b and stacking a wide surface in a pair of two to form a staircase, the sealing bag 50 formed of aluminum foil on all surfaces except one side of the top, bottom, left, and right surfaces Wrapped with

In order to manufacture such a sealing bag 50, the aluminum sheet is 0.05 ~ 0.5mm thickness and overlap the two sheets of aluminum foil coated with a thermoplastic adhesive resin along the outer surface of each other, and then overlap the outer surface of the three sides of the aluminum sheet It is manufactured to have an opening on one side by heat bonding production.

In addition, the sealing bag 50 is sequential so that Ny15μ for antistatic, PE15μ for preventing oxygen penetration, Al15μ for preventing outside air penetration, PE15μ for preventing oxygen penetration, LPP30μ for adhesion from the outer side It is laminated | stacked and formed.

In this way, the core material 40 wrapped in the sealing bag 50 is inserted into a separate vacuum decompression device (not shown in the figure) to discharge the air in the sealing bag 50 is inserted into the heat insulating material through the opening. .

That is, the vacuum encapsulation material 60 is manufactured by a method of sealing and removing the air by suctioning the air through an open portion in which the sealing bag 50 is not wrapped.

At this time, the vacuum insulation coefficient of the sealing bag 50 is less than 0.003 W / mok or less, the core material 40 at the time of pressure reduction is reduced to half the initial volume when the vacuum pressure is completed, the opening portion of 150 ~ 160 ℃ It is completed by sealing by heat bonding in the range.

Since the vacuum panel insulation material 60 is an outer shell material and the silica powder 12 is sealed by reducing the pressure inside the core material, the vacuum panel insulation material 60 has excellent thermal insulation property because the thermal conductivity coefficient of the gas is almost zero. Therefore, when the vacuum panel insulation 60 is used for building insulation and refrigerator insulation, etc., the insulation performance can be improved and the thickness of the insulation can be greatly reduced, so that the internal space can be expanded.

The vacuum panel insulation 60 is made of a back plate 70 having a back portion of the human body and a front plate 80 having a half area of the back plate 70 and dividing the front part of the body of the human body.

As shown in FIGS. 9 to 11, the rear plate 70 has a first neck groove 71 and a first arm groove 72 so that the neck and both arms are exposed at one end and both side ends of the vacuum panel insulation 60. To form the altar.

In addition, the first neck groove 71, the first arm groove 72, and the connecting means 90 made of a male and female form at the edge of the edge except for the lower end is configured.

In addition, the front plate 80 forms a second neck groove 81 corresponding to the first neck groove 71 at one end of the vacuum panel insulation 60 having a half area of the back plate 70.

On the other hand, a second arm groove 82 corresponding to the first arm groove 72 is formed at the other end.

At this time, the second neck groove 81 and the second arm groove 82, a pair of the corresponding structural form attached to the connecting means 90 made of a male, male form on the edge of the edge except the lower end.

In addition, the front surface of the front plate 80 may be configured by combining the pocket (84).

As shown in Figure 12, the connecting means 90 may be composed of male and female velcro tape.

As shown in Figure 12, the connecting means 90 may be configured as a male, male zipper (zipper).

Such, the rear plate 70 and the pair of front plate 80 is connected to the coupling means 90 to configure the winter clothes 100.

At this time, the back plate 70 and the front plate 80 is configured to be stitched with each other when the edge of the edge of the step shape when connected by the connecting means (90).

In this way, the winter clothing 100 is produced by connecting the back plate 70 and the front plate 80 with the connecting means 90, the first neck groove 71 and the second neck groove 81 can face each other and the neck can be exposed A space is formed, and the first arm groove 72 and the second arm groove 82 face each other to form a space that the arms can expose.

And, the winter clothing 100 is to use to wear in the form of a vest made of fiber material.
