入射を防ぎ、冷房用のエネルギーコストを軽減するため
の改良された遮光用フィルムに関する。
[Detailed Description of the Invention] The present invention relates to an improved light-shielding film that is applied to window glass surfaces of buildings to prevent sunlight from entering and reduce energy costs for air conditioning.

近時、原油価格の高騰に伴ない、消費エネルギーの節減
が叫ばれ、種々研究開発がなされている。
BACKGROUND ART Recently, with the rise in crude oil prices, there has been a call for reducing energy consumption, and various research and development efforts have been made.

中でも、夏の冷房費は、太陽光の屋内への入射がなけれ
ば、大巾に軽減されるものであるとされている。
In particular, summer cooling costs are said to be significantly reduced if sunlight does not enter indoors.

スからの透過光である。
Sunlight also shines on the walls of buildings, but the walls have a small effect on indoor temperature due to their own insulating effect, and most of the influence on room temperature comes from window glass. This is the transmitted light.

However, completely blocking this is problematic in terms of daylighting and increases lighting costs. Transmit light to a level that does not interfere with the brightness of the
A light-shielding film that has the functionality of blocking long-wavelength infrared rays that have a thermal effect as much as possible is used and is attached to window glass to block sunlight.

After cleaning the indoor surface of the window glass, the light-shielding film must be firmly attached one after another from one end, with the adhesive side facing the glass surface, so that there are no gaps between the film and the glass surface. However, in this case, air bubbles may remain between the glass surface and the film surface, which not only causes peeling and damage of the film surface during use, but also
The appearance was severely damaged.

However, if you want to bond the glass surface and the film surface tightly without introducing air bubbles, it requires a considerable amount of skill, so you have to rely on a professional installation company, which makes it difficult to use casually. However, it was also uneconomical.

That is, the present invention has a diameter of 0.5 m on the surface of the light-shielding film.
This is a light-shielding film in which small pores of m or more are opened so that the pore area ratio is 10% or less with respect to the total film area.

This thin film can be formed on the film surface by any method, such as adhesion, vapor deposition, lamination, or sputtering, as long as it can firmly and stably join the two. Among them, vacuum evaporation is a method that can stably form a uniform thin film. It is particularly preferable because it forms

次に、フィルムの他面に接着層を形成するが、該接着層

Next, an adhesive layer is formed on the other side of the film, and the adhesive layer may be an adhesive layer or an adhesive layer that adheres when wetted with water or other solvent.

また、必要により離型剤シート層を設けてもよい。Further, a release agent sheet layer may be provided if necessary.

The film surface has a diameter of 0.51! Small pores of L7IL or more are opened so that the pore area ratio is 10% or less with respect to the membrane area.

ここで、孔の直径が0.5間以下では貼付の際、脱泡し
にくいし、フィルム製造時も困難であるのでよくない。
Here, if the diameter of the pores is less than 0.5 mm, it is not good because it is difficult to defoam during pasting and it is also difficult to manufacture the film.

また、開孔面積率が全面積の10%を越えると、遮光効
果が減少し、フィルム面も弱くなり好1しくなく、開孔
面積率を10饅以下にすることが必要である。
Further, if the open pore area ratio exceeds 10% of the total area, the light shielding effect will decrease and the film surface will become weak, which is not preferable, so it is necessary to keep the open pore area ratio below 10%.

このような制約と、脱泡に必要な開孔密度、云いかえれ

大きさは、直径5mm以下である方がよい。
In order to satisfy such constraints and the opening density required for defoaming, in other words, the opening interval of the small holes, the size of each small hole is preferably 5 mm or less in diameter.

After cleaning the indoor surface of the window glass, the light-shielding film having the above structure is mechanically pasted sequentially from one end to the other end with the adhesive side facing the glass surface. Air bubbles that occur between the glass surface and the film surface are absorbed by the small perforated holes, and no air bubbles remain between the glass surface and the film surface, resulting in a beautiful appearance and a light shielding effect that is better than conventional It was almost as good as the quality.

なお、本考案に釦いて、開孔面積率は次の式に従った。In addition, according to the present invention, the open pore area ratio was determined according to the following formula.
