Description

The present invention relates to a heat shield and heat insulating material.

As disclosed in Patent Document 1, a heat shield sheet is generally used in which the front and back surfaces of a foamed polyethylene sheet having a hexagonal honeycomb structure are sandwiched with a thin metal foil.

The heat shield material using the conventional hexagonal honeycomb structure core material has excellent mechanical strength, but when covering piping pipes, etc., it can be easily bent, cut, etc. with a flexible material. Material is required. The present invention is to provide a heat-shielding heat insulating material that can be easily processed in on-site pipe covering work or the like.

The present invention relates to a heat-shielding heat-insulating material characterized in that a thin metal foil is attached to the front and back of a heat-insulating plate in which square-shaped gaps are continuously provided in a predetermined gap on a flat plastic heat-insulating material.

The present invention is a heat-shielding and heat-insulating material that can be easily cut, bent, and the like at a construction site.

It is a diagram of making the core material of this invention.

The material of the foamable quadrangular mesh structure sheet used in the present invention may be a flexible material that can be easily wrapped around the outer circumference of a pipe or the like and has a heat insulating effect. As an example, a foamable polyethylene sheet is preferably used. The size of the mesh of the quadrangle may be a parallelogram, a rhombus, a rectangle, or a square having a side of about 1 to 4 cm. A metal foil is welded or adhered to the front and back of the mesh material.

When a thin metal foil, for example, a high-purity aluminum foil sheet is attached to the surface, the emissivity of aluminum is low, so that the effect of blocking the transfer of heat from the outside to the heat insulating material side of the inside as radiant heat is high.

Using a quadrangular void has a shorter porosity in the quadrangle than the hexagonal honeycomb in terms of the total length of the sides per unit area, so the porosity is larger in the quadrangle, which has a heat insulating effect. It can be expected to be higher.

The use of a heat insulating material having a quadrangular void is inferior in mechanical strength to a heat insulating material having a hexagonal honeycomb structure, but on the other hand, it has an advantage that work processes such as bending, winding, and cutting can be easily performed.

As shown in FIG. 1, a polyethylene foam having a thickness of 10 mm and a width of 300 mm was cut with a length of 60 mm and a gap of 5 mm, and widened to a width of 1000 mm. A high-purity aluminum foil sheet was attached to the front and back to create a heat-shielding and heat-insulating sheet. Since this prototype is thinner than general heat insulating materials, it has the feature of being excellent in space utilization, and the material is soft and can be airtightly sealed, reducing heat exchange and decree exchange of windows and corners. It can be expected to have the effect of blocking and suppressing the occurrence of dew condensation and mold. Therefore, heat insulation, heat insulation, and moisture resistance can be ensured by applying the heat shield / residual heat material without separately forming a moisture barrier. Furthermore, the sound insulation of the aluminum foil sheet and the sound absorption of the polyethylene foam can be expected to have a soundproofing effect. Compared to other heat insulating materials, it has the same heat insulating properties, the material cost and construction cost are low, the construction period can be shortened, and it is thin, light, soft, and has excellent workability without fiber scattering, especially in the corners. It has the feature that it is easy to break or bend.

It can be used as a heat shield / heat insulating material sheet for piping covering work.
