Description

[Detailed description of the invention] This invention allows even amateurs to easily apply it on-site to areas that require insulation or where it is desired to prevent condensation, such as the walls of buildings, the surfaces of sash frame materials, and frame materials. Moreover, even if the adhesive fails, it can be peeled off and reapplied, and when applied, wrinkles and unevenness do not easily occur on the surface, resulting in a beautiful finish, and the number of layers is small. Therefore, the present invention relates to a simple pasting heat insulator that can be manufactured easily and at low cost.

In recent years, there has been a widespread demand for energy conservation due to the soaring price of oil, and wall materials containing insulating materials such as glass wool and rock wool inside the walls are also being used to maintain the cooling and heating effects of buildings. It is becoming widely used.

However, many existing buildings do not use building materials with such excellent insulation effects, and even in newly built buildings, there are many areas where the insulation effect is still insufficient in the sash and other parts. It is also true that it exists.

For example, in the case of a sash, the metal part of the sash usually occupies 20 to 45% of the opening, so increasing the insulation effect of this metal part is extremely effective in terms of energy conservation. .

In this current situation, even if there are areas where the insulation effect should be further improved or where dew condensation should be prevented, there was no way to improve the insulation effect of those areas in a good manner, so conventionally they were left as they were. It was.

As a result of various studies to solve these conventional problems, the inventor of the present invention has found that it has a high heat insulation effect, can be easily and neatly pasted at a desired location even by an amateur, and can be easily applied even if it is not pasted properly. It can be peeled off once and reattached, and even if it is reattached in this way, wrinkles and unevenness do not easily occur on the surface, and since the number of layers is small, it can be manufactured at low cost and easily. The present invention was completed by successfully producing a simple adhesive heat insulating material that could be attached.

In other words, the present invention has an unfoamed portion remaining on the back side, a thickness of 0.5 mm to 10 mm, and a thermal conductivity of 0.05 Kcal/
The surface of the soft foam has a thickness of m・hr・℃ or less.
A decorative sheet consisting of a semi-rigid vinyl chloride sheet measuring 0.2 mm to 0.8 mm and containing 20% to 55% by weight of plasticizer is attached, and the adhesive applied to the back side of the foam The present invention provides a heat insulator for simple attachment, characterized in that a release material is adhered.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the simple pasting heat insulator according to the present invention will be described in detail below with reference to the drawings.

The drawing is an enlarged explanatory view of one embodiment of the simple pasting heat insulator according to the present invention.

In the figure, 1 has an unfoamed portion 1a remaining on the back side, has a thickness of 0.5 mm to 10 mm, and has a thermal conductivity of 0.05 Kcal/
It is a soft foam having a temperature of m·hr·° C. or less, and the foam 1 is preferably made mainly of a soft and highly flexible material such as foamed polyethylene, foamed vinyl chloride, or foamed rubber. 2 is the thickness of the foam 1 that is adhered to the surface of the foam 1 by an adhesive 3 such as an adhesive, adhesive or double-sided adhesive tape, or by welding.
This is a decorative sheet made of a semi-rigid vinyl chloride sheet measuring 0.2 mm to 0.8 mm and containing 20% to 55% by weight of a plasticizer. The decorative sheet 2 may have a colored or patterned surface, or may be a foamed sheet with some unfoamed parts left. 4 is an adhesive applied to the unfoamed portion 1a on the back side of the foam 1; 5 is a release material such as release paper or release film adhered onto the adhesive 4;

In this configuration, the thickness of the foam 1 is 0.5 mm.
The thickness must be in the range of ~10mm
If the thickness is less than 0.5 mm, it will be too thin and the insulation effect will not be sufficient, and if the thickness exceeds 10 mm, the flexibility will deteriorate and it will not be possible to adhere it in a state that matches the shape of the object to which it is attached. . Also, the thermal conductivity of foam 1 is
The reason why it must be below 0.05 Kcal/m·hr·°C is because if the thermal conductivity exceeds 0.05 Kcal/m·hr·°C, the heat insulating effect as a heat insulator will be insufficient. Furthermore, the unfoamed portion 1a of the foam 1 must remain on the back surface of the foam 1 because the release material 5 can be peeled off from the adhesive 4 to provide insulation for simple application of the present invention to a wall or other surface where insulation is required. Foam 1 is pasted on the body, and when the adhesion is not done well, the adhesive force of the adhesive 4 is too strong when the adhesive is peeled off and then re-attached.
This is because it is necessary to provide a strong portion to prevent the back side of the foam from adhering to the adhesive 4 and tearing the foam 1 into two layers.

In addition, the plasticizer must be added to the decorative sheet 2 in the range of 20% to 55% by weight.If less than 20% by weight of the plasticizer is added, the surface becomes hard as a heat insulator for simple application. If it is added in excess of 55% by weight, the surface will become too soft as a heat insulator for simple attachment, making it difficult to maintain a state that matches the shape of the object to be attached. The reason why the thickness of the decorative film 2 must be in the range of 0.2 mm to 0.8 mm is because it faithfully reflects the wrinkles and unevenness that occur on the surface, resulting in a marked deterioration of the appearance. The thickness is too thin, and the wrinkles and unevenness that occur on the surface side of the foam 1 are reflected on the surface, significantly impairing the appearance, and the thickness is 0.8
This is because if the thickness exceeds mm, the flexibility of the heat insulating material for simple adhesion becomes poor and it may not be possible to adhere it in a state that matches the shape of the object to which it is to be adhered.

The simple pasting heat insulator according to the present invention having such a structure is first cut to the width and length according to the size of the object to be pasted, and then pasted onto the adhesive 4 on the backmost side. All that is required is to peel off the release material 5 that has been applied and stick it with the adhesive 4 onto an object that requires a heat insulating effect.

When applying this product, if wrinkles occur on the surface or if it cannot be applied to the desired position and the position shifts, it may not be possible to apply the adhesive even if it has been applied once. If the adhesive 4 and the foam 1 are stuck together by the strong unfoamed part 1a on the back side of the foam 1, the adhesive 4 and the foam 1 can be easily pasted according to the present invention. The foam 1 will not be torn into two layers when the object to which the heat insulator is attached is peeled off, and the decorative sheet 2 will not have wrinkles or unevenness on its surface due to its appropriate amount of plasticizer and thickness. Even an amateur can easily and beautifully apply the adhesive to a desired location because it is difficult to cause any scratches.

As detailed above, the simple pasting heat insulator according to the present invention is such that the foam 1 stuck to the back side of the front decorative sheet has an unfoamed portion 1a remaining on the back side, Further, an adhesive 4 is attached to the back surface of the foam 1, and a release material 5 is attached to the adhesive 4.
It is used after being peeled off from the adhesive 4, and it does not easily cause wrinkles or unevenness on the surface, and it can be peeled off and re-attached after being pasted, and when used, it can be applied immediately by simply peeling off the release material 5. It is easy to work with because it can be worn on the skin, and it has various advantages such as excellent heat insulation and a beautiful surface, so even amateurs can easily stick it to the desired location without getting their hands dirty. , its practical value is enormous.
