まれていた。 Sheets that have both light and heat shielding properties are used in large quantities to adjust the amount of incident light in agricultural and horticultural facilities such as outdoor tent houses for sericulture, greenhouses, and other various buildings, as well as to prevent temperature changes due to heat transfer. used for. However, conventional light-shielding and heat-shielding sheets have been insufficient in terms of heat-shielding performance and light-shielding properties, and improvements have also been desired in terms of durability.
本考案は上述のような現状を背景に、特に遮熱

8 is an adhesive layer (molten polyethylene cooled and solidified).
本考案によるシートの構成材料について次に説
明する。 The constituent materials of the sheet according to the present invention will now be described.
表層のポリエステルフイルム１は、これを太陽
光線側にして使い、光線反射面であるアルミニウ
ム薄膜２の支持体兼保護膜となるものであるか
ら、厚さ５〜50μで無着色のものを用いる。 Since the surface layer polyester film 1 is used facing the sunlight side and serves as a support and a protective film for the aluminum thin film 2 which is the light reflecting surface, a non-colored polyester film 1 with a thickness of 5 to 50 microns is used.
アルミニウム蒸着膜の厚さは0.01μ以上とする
ことが望ましい。 It is desirable that the thickness of the aluminum vapor-deposited film be 0.01μ or more.
補強用織物３は、シート全体の補強に有効なこ
とはもちろんであるが、その本来の役割は、アル
ミニウム蒸着膜と厚く柔かな発泡ポリエチレンシ

で織られた狭義の織物のほか、プラスチツクフイ
ルムを細いテープ状に分割して織物状組織を形成
したもの、あるいはこれらをポリエチレンフイル
ムとラミネートしたものなどを含むものである。
好ましい具体例としては、日本石油化学(株)の日石
ワリフ（商品名）がある。 The reinforcing fabric 3 is, of course, effective in reinforcing the entire sheet, but its original role is to play an intermediate role between the aluminum vapor-deposited film and the thick, soft foamed polyethylene sheet, and prevents the vapor deposition that would otherwise occur. The purpose is to prevent destruction of the membrane due to excessive local deformation. The term woven fabric used here includes not only woven fabrics woven on a loom in the narrow sense, but also woven fabrics made by dividing plastic film into thin tapes, or those laminated with polyethylene film. .
A preferred specific example is Nisseki Warif (trade name) manufactured by Nippon Petrochemicals Co., Ltd.
発泡ポリエチレンシート４は言うまでもなく積
層シート全体の断熱性の向上に有効なものであ
り、断熱性はこの層が厚ければ厚いほど良くなる
が、あまり厚いとシートの取扱いが困難になるか
ら、通常0.5〜3.0mm程度の厚さのものを用いるこ
とが望ましい。またポリエチレンの発泡倍率は10
〜50倍程度の高率であることが望ましい。 Needless to say, the foamed polyethylene sheet 4 is effective in improving the insulation properties of the entire laminated sheet, and the thicker this layer, the better the insulation properties, but if it is too thick, it will be difficult to handle the sheet, so it is usually It is desirable to use one with a thickness of about 0.5 to 3.0 mm. Also, the foaming ratio of polyethylene is 10
A high rate of ~50 times is desirable.
基布５の素材は、補強用織物３に用いるものと
して前に述べた織物の中から選んでよいが、全体
が、又は少なくとも露出する表面の大部分が、黒
又はこれに近い暗色に着色されていることが必要
である。 The material of the base fabric 5 may be selected from among the fabrics mentioned above for use in the reinforcing fabric 3, but the entirety, or at least the majority of the exposed surface, may be colored black or a dark color close to this. It is necessary that the
以上のような材料を溶融ポリエチレンを用いて
接着して本考案のシートを製造する場合の接着順
序や接着方法は任意である。 When manufacturing the sheet of the present invention by bonding the above-mentioned materials using molten polyethylene, the bonding order and bonding method are arbitrary.
本考案によるシートは以上のような構成のもの
であるから、従来なかつたようなすぐれた遮熱性
能を示し、同時に遮音性をも有するものである。
しかも発泡ポリエチレンシートを芯層にしたこと
による全体の物性や耐久性の劣化もないから、多
くの用途においてすぐれた性能を発揮するもので
ある。 Since the sheet according to the present invention has the above-described structure, it exhibits excellent heat insulation performance that has never been seen before, and at the same time has sound insulation properties.
Furthermore, since there is no deterioration in the overall physical properties or durability due to the use of the foamed polyethylene sheet as the core layer, it exhibits excellent performance in many applications.
