Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package of a heat-insulating material which is particularly useful for filling walls, roofs, floors and the like of buildings and structures, and useful as a core material for building panels.

[0002]

2. Description of the Related Art Conventionally, as a heat insulating material to be filled between frames, the main material is industrial inorganic fibers such as glass wool, rock wool, and asbestos in order to improve heat insulation of walls, roofs and floors of buildings and structures. Insulated foams such as polystyrene boards, polyurethane boards, isocyanurate boards, phenol boards, etc., which are foamed by chemical reaction are used. In general, a plurality of materials are stacked and the periphery thereof is covered with a paper-based or vinyl-based sheet and packed.

[0003]

However, the fixed heat insulating material mainly composed of industrial inorganic fibers or synthetic resin foam is poor in elasticity (cushioning property) and rich in plasticity. Once packed, it has the property of not returning to its original state, and these packages require attention to impact and external pressure. Also, due to such properties, the volume of these packages must be the same as the volume of the heat insulating material itself, resulting in bulkiness, poor transport efficiency, and high cost. Furthermore, in particular, when packing, unpacking, or when the package is torn, the handling of the needle-shaped fiber will be stuck on the hands and feet of the workers, especially when packing, unpacking, or breaking the package. Piercing the skin and causing inflammation in the skin, breathing into the respiratory tract and lungs, and damaging these respiratory systems.Work requires great care and equipment such as dustproof clothing and a dustproof mask. Was.

[0004]

In order to solve the above-mentioned problems, the present invention provides a heat insulating material mainly composed of wool, and forms a closed space by covering the package with a sheet-like material. Since the volume of the heat insulating material has been reduced by reducing the internal pressure, the efficiency of transportation and loading on trucks has been improved. By forming it as odorless, it is odorless and non-irritating, it can prevent the generation of dust and allergies, and the generation of volatile organic compounds. It is easy to recycle, and by mixing polyester fiber with this, shape retention, elasticity,
Since the flatness and strength have been improved, the heat insulating material has a strong restoring force even after unpacking, and proposes a heat insulating material package that easily restores to its original bulk.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a package of a heat insulating material according to the present invention. FIG.
(A), (b) is explanatory drawing which shows a typical example of the said package A. FIG. That is, as shown in FIG. 2, which is a cross-sectional view taken along the line II in FIG. 1A, the packing body A forms a heat insulating material group B by stacking a plurality of heat insulating materials 1 formed in a mat shape. The periphery of the heat insulating material group B is covered with the sheet material 2 to form a closed space C, and the volume of the heat insulating material group B is reduced by reducing the pressure in the closed space C.

As shown in FIG. 3, for example, the heat insulating material 1 is made of wool as a main material, mixed with polyester fiber, and formed into a mat with an arbitrary thickness, width, length and density. is there.

[0007] Wool as a main raw material of the heat insulating material 1 is a natural (natural) material, and is obtained by entangled in a mat form a fibrous material formed by performing purification, washing, disinfecting treatment and the like as required. Yes, it has elasticity and shape retention, and is rich in heat insulation.

Since wool is a natural product, it is odorless, non-irritating, free of dust and allergies, and free of volatile organic compounds, and is good for health. Further, since wool is a natural organic substance, it can be easily recycled as compost or fertilizer by, for example, directly corroding waste materials, and is environmentally friendly.

The polyester fiber is mixed with 1 to 40 parts by weight (for example, 5, 10, 15, 20, 25, 30, 35 parts by weight) with respect to 100 parts by weight of wool when the heat insulating material 1 is manufactured. This is a sub-material that functions as a shape maintaining material (shape keeping material), a strength improving material, an elasticity-adding material, a flat plane formation, and the like of the heat insulating material 1.

[0010] Therefore, by mixing the polyester fiber, the correctability and the elasticity are improved. For example, when the package is packed, it easily returns to the original bulk easily.

At any stage before, during, or after the production of the heat insulating material 1, various flame retardants are added to provide a fireproof property.
The heat insulating material 1 can be improved in fire resistance, or added with a deodorant, an insect repellent, and a waterproofing agent (water repellent) to provide various functions.

The density of the heat insulating material 1 is 20 to 9
0 kg / cubic meter, thermal conductivity 0.02-
It is of the order of 0.09 Kcal / mh ° C., and has a heat insulation performance equal to or higher than that of a conventional fixed heat insulating material.

The sheet-like material 2 covers the periphery of a heat insulating material group B composed of a plurality of heat insulating materials 1 stacked and packed to form a closed space C therein. It functions as a surface protection material.

u), one or two or more of synthetic resin sheet, rubber sheet, cloth sheet, gypsum paper, aluminum hydroxide paper, glass fiber nonwoven fabric, etc., or waterproof treatment,
It is made of flame-retarded material.

The closed space C formed by the sheet 2 is decompressed by using a device (not shown) such as a compressor or a vacuum pump to reduce the internal pressure. is there.

As a result, as shown by the arrow in FIG. 4, the volume of the heat insulating material 1 is reduced, so that the transport efficiency and the loading efficiency on the truck are improved, and the hermetic material 1 is completely sealed to prevent bacteria and other germs from entering. It can also improve safety.

The package A shown in FIG.
The surplus portion 3 of the sheet-like material 2 in the package A shown in FIG. 3A is cut off, and the transport efficiency and the loading efficiency are further improved in a rectangular parallelepiped shape.
