Description

Heat reflection insulation {A heat insulater}

The present invention relates to a heat reflection insulation material, and to a heat reflection insulation material that is installed on the inner wall of the building to prevent the heat transfer of the indoor and outdoor to maintain a proper temperature in the room.

In general, the insulation is constructed between the inner and outer walls of the building to prevent heat loss in the room by delaying and blocking heat transfer inside and outside due to conduction, convection, and radiation phenomena, which has an insulation function that can minimize energy consumption for heating and cooling. It is a building material.

The insulation is mainly a foamed resin of various organic materials such as polystyrene foam, polypropylene foam, or the like, or an inorganic fiber nonwoven fabric such as an organic fiber-based nonwoven fabric or a felt-shaped insulation material, a long glass fiber, glass wool, etc. Felt type insulation is used.

In addition, such a heat insulator has been used by bonding a heat reflector, such as aluminum, titanium, silver, etc. to the heat insulator through an adhesive or the like for higher heat insulating effect.

However, the heat insulator to which the heat reflection material is adhered has no water passage to penetrate moisture due to the inherent micropores of the heat insulator made of nonwoven fabric or foamed resin, and there is a problem of poor breathability.

Accordingly, due to the temperature difference between warm indoor air and low temperature outdoor air after construction of the insulation, moisture condensation occurred in the insulation as water droplets.In this case, it was difficult to discharge moisture to the outside of the insulation. However, there is a problem that the humidity of the sealed space is increased because the ventilation between the wall and the insulation is not free.

In particular, if the low temperature phenomenon outside the winter season, condensation occurred and the humidity increased, the wood structure was corroded, and in the case of the concrete structure, there was a problem of condensation entering the room through the cracks of the concrete. When the dew condensation is frozen, there is a problem in that the condensation occurs on the interior surface of the inner wall by cooling the inner wall and mold occurs in the interior.

The present invention is to solve the above problems, it is an object of the present invention to provide a heat reflection insulating material that prevents the occurrence of condensation as the ventilation in the heat insulating material is made smoothly and moisture permeable and waterproof.

According to an aspect of the present invention,

A heat reflection insulating material layer having an aluminum layer coated on the upper end of the first nonwoven fabric layer to be permeable and waterproof;

An insulation layer made of a foam positioned at a lower end of the heat reflection insulation layer;

A film layer in which micropores are formed at a lower end of the insulation layer;

It is located at the bottom of the film layer provides a heat reflection insulating material comprising a; non-woven layer to protect the film layer.

In addition, the aluminum layer provides a heat reflection insulating material, characterized in that the aluminum is partially coated on the upper end of the first nonwoven fabric layer to form a condensation prevention hole that transmits moisture and blocks the transmission of water droplets.

In addition, the condensation preventing hole provides a heat reflection insulating material, characterized in that formed at least two spaced apart periodically or aperiodic.

In addition, the heat insulating material layer provides a heat reflection insulating material, characterized in that consisting of polyethylene foam or polyurethane foam having a pore form of diamond structure.

In addition, the film layer provides a heat reflection insulating material, characterized in that made of polyethylene or polypropylene resin having a micropores of 1 ~ 7㎛.

As described above, the heat reflection insulating material of the present invention has excellent heat insulating properties through the heat insulating effect of each layer, that is, the heat reflection insulating material layer, the heat insulating material layer, the film layer, and the nonwoven fabric layer, as well as due to the temperature difference between indoor and outdoor. Even if moisture is generated inside the heat insulator, the moisture can be easily vented to the outside of the heat insulator because the air passage is well formed in the heat insulator, and the ingress of water droplets formed outside the heat insulator can be blocked. Can be prevented from occurring, thereby preventing corrosion or decay of wood or concrete structures of buildings.

2 is a sectional view of Fig. 1;

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited to the embodiments shown in the drawings.

1 is a perspective view of a heat reflection insulating material according to an embodiment of the present invention, Figure 2 is a cross-sectional view of FIG.

As shown therein, the heat reflection insulating material 1 of the present invention comprises: a heat reflection insulating material layer 10 having an aluminum layer 12 coated on the upper end of the first nonwoven fabric layer 11 to be permeable and waterproof; A heat insulation layer 20 made of a foam positioned at a lower end of the heat reflection insulation layer 10; A film layer 30 formed with micropores 31 positioned at a lower end of the insulation layer 20; And a second nonwoven fabric layer 40 positioned at the bottom of the film layer 30 to protect the film layer 30.

First, the first nonwoven fabric layer 11 of the heat reflection insulation layer 10 is formed of a polyester short fiber of the organic fiber by a needle punching process, the first nonwoven fabric layer 11 as described above has a plurality of pores therein The layer is formed to have breathability and heat insulation effect, and because the fibers are entangled due to the irregular arrangement of the fibers, it is possible to fix takapin or nails entangled in the tangled fibers and not to be detached.

The upper end of the first nonwoven fabric 11 is formed by coating an aluminum layer 12 to insulate through heat reflection. In more detail, the aluminum layer 12 is preferably formed by partially coating aluminum on the top of the first nonwoven fabric layer 11 so that moisture condensation is prevented and condensation preventing holes 121 are formed to block water droplets from being penetrated.

At this time, the partial coating is to form a condensation preventing hole 121 at the same time as the aluminum layer 12 is formed. That is, the aluminum layer 12 having the condensation preventing holes 121 is formed by coating only the upper surface of the first nonwoven fabric layer 11 of the remaining portion except for the portion where the condensation preventing holes 121 are to be formed. It is.

The partial coating method of the aluminum is sprayed on the upper end of the first nonwoven fabric layer 11 with a solution of aluminum, or the first nonwoven fabric layer 11 is immersed in a container containing the liquefied aluminum coating method The aluminum layer 12 may be formed by, for example, the present invention. In the present invention, the aluminum layer 12 may be selectively applied to the upper surface of the first nonwoven fabric layer 11 through a tool or a machine such as a brush. It is preferable to form aluminum so that the aluminum can be partially coated more easily.

The condensation preventing hole 121 of the aluminum layer 12 formed as described above has a fine size that transmits moisture in the heat insulating material generated by the temperature difference between the inside and the outside after construction to the outside, and water droplets generated outside the heat insulating material are waterproof. It is formed as a hole, the condensation preventing hole 121 is preferably formed to have a size of 1 ~ 7㎛ can be performed well moisture permeability and waterproof function.

In addition, the condensation preventing hole 121 is formed so that two or more are spaced periodically or aperiodic. That is, the condensation preventing hole 121 is partially coated to prevent the aluminum from being coated at regular intervals or at regular intervals so that the condensation preventing hole 121 can be formed in a state where the predetermined distance is spaced apart from the heat reflection insulation layer 10. Without the condensation prevention hole 121 at random without the aluminum can be partially coated.

The heat reflection insulation layer 10 formed as described above may have a heat insulation effect, and may be firmly fixed during construction due to the first nonwoven fabric layer 11, and the condensation prevention hole 121 formed in the aluminum layer 12 may be formed. Due to the ventilation, as well as moisture generated in the heat insulating material can be transmitted to prevent condensation from occurring.

The heat insulating material layer 20 positioned at the bottom of the heat reflection insulating material layer 10 may be a foam of an organic material such as polyethylene foam, polyurethane foam, or the like. The insulation layer 20 made of such a foam can slow down the heat transfer due to a plurality of pores formed therein, and thus has excellent thermal insulation effect and excellent thermal insulation function.

In addition, the pore shape of the foam constituting the insulation layer 20 can be manufactured in various forms such as triangle, bubble, honeycomb form, but to have a diamond structure formed in a diamond shape it can be carried out better aeration of the insulation Preferably, the processing of the foam having a diamond structure is a known matter, so the description thereof will be omitted.

The film layer 30 positioned at the lower end of the heat insulating material layer 20 has a micropore 31 so that the specific gravity is low, and has a heat insulating effect, and the inside of the entire heat insulating material smoothly through the micro pores 31. It is made of water, moisture is permeable, and water droplets have a function of waterproofing.

At this time, the film layer 30 is preferably made of polyethylene or polypropylene resin having a micropores 31 of 1 ~ 7㎛, wherein the size of the micropores 31 of 1 ~ 7μm to transmit moisture to the outside of the heat insulating material This is possible, but the size of the water droplets are not absorbed.

Finally, the second nonwoven layer 40 positioned at the bottom of the film layer 30 is a nonwoven fabric formed by forming an organic fiber such as polypropylene or polyester by a span bonding or needle punching process, which is according to the present invention. Complementing the insulation of the heat reflection insulating material to protect the film layer 30 to prevent the weak film layer 30 is easily torn, and prevents water condensation through the fibers forming the second nonwoven fabric layer (40).
