Description

[Detailed Description of the Invention] The present invention relates to a heat insulating material useful in architecture and structures. More specifically, it relates to a heat insulating material that not only provides heat insulation properties to internal and external walls, roofs, etc., but also has an air cycle function.

With the spread of energy conservation laws, the use of insulation materials in buildings is rapidly increasing. However, simply filling each part of a building with insulation material is not sufficient to prevent condensation from occurring, and water vapor cannot be reliably exhausted, leading to deterioration in the performance of insulation materials and damage to construction materials. It was often seen that this caused corrosion, etc.

In order to eliminate these drawbacks, the present invention forms the heat insulating material itself from a synthetic resin foam with a closed cell structure, suppresses the permeability of water vapor, etc., and also includes a continuous line on at least one outer peripheral surface of the synthetic resin foam. forming a recessed portion, and covering at least one outer circumferential surface continuous with the open end of the recessed portion, or the other surface with a plate-like body, and drilling a small opening or an opening in a portion corresponding to the recessed portion, The present invention proposes a heat insulating material that is equipped with air cycle, heat insulation, reinforcement, moisture proofing functions, etc. within the heat insulating material itself.

An embodiment of the heat insulating material according to the present invention will be described in detail below with reference to the drawings. FIGS. 1a and 1b are perspective views showing the heat insulating material according to the present invention, in which 1 is a synthetic resin foam (hereinafter simply referred to as foam) whose external shape is, for example, a plate with the cross section shown in FIGS. 2a to 2j, It is a columnar object. That is, figure a is a rectangle, figure b is a square, figure c is an oblong shape, figure d is a trapezoid, figure e is a half-moon, figure f is a rhombus, figure g is a slope shape, figure h is an Otsu-shape,
Figure i shows a partially cutaway rectangle, and figure j shows a triangle. Form 1 also has insulation material, core material,
For example, polyurethane foam, polyisocyanurate foam, phenol foam, polyethylene foam, vinyl chloride foam, polystyrene foam, polyacetal foam, polyamide foam, unsaturated polyester foam, epoxy form, urea form,
and modified foams thereof, and particularly foam 1 preferably has fire retardant properties, a closed cell structure, and a certain degree of shape retention. In addition to the above-mentioned outer shape, the form 1 can be formed into an outer shape depending on the area of use. Reference numeral 2 denotes a concave portion which is linear and continuous with at least one of the outer circumferential surfaces of the form 1, and is formed, for example, in the cross section shown in FIGS. 3a to 3k. That is, figure a is rectangular, figure b is semicircular, figure c is square, figure d is oblong, figure e is triangular, and figure f is square.
The figure shows a modified trapezoidal shape, the g figure shows a trapezoidal shape, the h figure shows a polygonal shape, the i figure shows a wavy shape, the j figure shows a continuous rectangular shape, and the k figure shows an elliptical shape. Further, the appearance of the recessed portion 2 is formed, for example, as shown in FIGS. 4a to 4d.
That is, figure a shows a straight line, figure b shows a tapered shape in the width direction, figure c shows a curved shape, and figure d shows a tapered shape in the thickness direction of the form 1. Note that the recess 2 can be formed by cutting it from the molded body or by using a mold. Reference numeral 3 is a plate-like member that closes the open end of the recess 2 and covers the entire outer peripheral surface of the recess 2 to form a gap 4 for an air circulation path. In addition, the plate-like body 3 covers not only the outer circumferential surface where the recess 2 exists, but also the outer circumferential surface opposite to this surface, or at least one of the other outer circumferential surfaces continuous with the recess 2, and forms the shape retaining material of the form 1. , and functions as a mechanical strength reinforcing material, a mold release material during manufacturing, a moisture proofing material, a sound insulating material, and a reflecting material. Further, the plate-shaped body 3 is provided with microholes 5 or openings 5a at least at the upper and lower ends or at necessary locations. The micropores 5 or openings 5a serve as suction for air cycle.
It serves as an exhaust hole, and the size of the micropore 5 ranges from microns to millimeters.
The type or two or more types of openings 5a are set according to the amount of intake and exhaust. In addition, micropores 5 and 5
The distribution of a is as shown in FIGS. 5a to 5e. In other words, in figure a, the upper and lower ends of the plate-like body 3 are rectangular, in figure b, triangular, in figure c, both ends have a high density and in the middle, the distribution is coarse, and in figure d, the entire surface has a density distribution depending on the purpose. This is a case where the distribution is made with a difference, and Figure e shows the case where openings 5a are provided at both ends. Furthermore, the material of the plate-like body 3 is one having one or more of air impermeability, form retention, flexibility, sound insulation, heat insulation (reflection), etc., such as a synthetic resin plate, a metal plate, Kraft paper, asbestos paper, gypsum paper, non-woven fabric, cardboard, asphalt felt, metal foil (Pb, Al,
Cu, Fe), synthetic resin film, etc., or 2
Seeds or more are laminated to form a sheet or molded product. Note that the form 1 and the plate-shaped body 3 are integrated using an adhesive, a mold, an adhesive tape, or the like.

What has been described above is only one embodiment of the heat insulating material according to the present invention, and a plurality of recesses 2 may be provided in the form 1 as shown in FIGS. It is also possible to fix the plate-shaped body 3 in this way. That is, in figure a, the plate-like body 3 is placed on the outer peripheral surface of the form 1 in the longitudinal direction, in figure b, the plate-like body 3 is placed on the entire outer circumferential surface of the form 1, and in figure c, the plate-like body 3 is placed on the entire outer circumferential surface of the form 1 in the longitudinal direction. This is a heat insulating material in which a plate-like body 3 having a gap 4 is fixed to four outer circumferential surfaces, and one outer circumferential surface thereof. In addition, in figure d, the plate-like body 3 is placed on the outer peripheral surface of the form 1,
Figure e shows a heat insulating material in which a plate-like body 3 is provided on the opposing outer peripheral surface of the form 1.

As mentioned above, according to the heat insulating material according to the present invention,
In addition to having heat insulation, air cycle, and moisture resistance, it is lightweight, inexpensive, and has excellent processability and construction properties, and has sufficient mechanical strength with little performance deterioration as described above.
