ている(実公昭37−213308号公報、実公昭36
−32609号公報等参照)。<Prior Art and Problems to be Solved by the Invention> Conventionally, laminates used as material sheets for protective covers for vehicles, for example, have been woven fabrics with waterproofing applied to one or both sides, or woven fabrics with one side waterproofed. It is known that a synthetic resin coating layer is formed on one side and an elastic body is laminated on the other side (Utility Model Publication No. 37-213308, Utility Model Publication No. 36/1983).
-Refer to Publication No. 32609, etc.).

より、車内が非常に高温状態となる等の弊害があった。Although it provided good protection against shocks and other impacts, no consideration was given to the harmful effects of sunlight falling on the ground, and in midsummer, the inside of the car could become extremely hot due to infrared rays that passed through the protective cover. There were some negative effects.

。In addition, near ultraviolet rays in a specific wavelength range, such as near ultraviolet rays, that pass through the protective cover affect the painted surface of a vehicle, causing problems such as deterioration of the paint or generation of cracks in the painted surface.

供することを目的としている。As a result of extensive testing and research in order to eliminate the disadvantages of conventional laminates used as materials for protective covers of vehicles, the present invention has revealed that a laminate having the laminate structure described below has a high resistance to infrared rays. By changing the irradiation surface,
The object of this invention is to provide a laminate suitable for use as a material for protective covers of vehicles, etc., by discovering and achieving different amounts of infrared rays transmitted.

When the surface side is the infrared irradiation surface, the infrared rays are substantially cut off, and when the base film side is the infrared irradiation surface, the infrared rays are transmitted. It consists of a laminate made of laminates.

Conversely, in the middle of winter, if the vehicle is covered with the base film side facing outward, the interior of the vehicle can be kept warm.

シート面側を外側(赤外線照射面側)にして車両をカバ

。When the sheet side that has many air pockets inside is set as the infrared irradiation surface, the infrared rays bend at the wall surface of the air pockets in the sheet, and most of the infrared rays do not reach the surface of the metal vapor deposited layer laminated on the other side. comes into contact with the incident from an oblique direction,
Since it is cut on the surface of the metal vapor deposited layer without passing through the laminate, if this laminate is used to form a protective cover for a vehicle and the vehicle is covered with the sheet side facing outward (infrared irradiation side). It is understood that the inside of the car does not become hot.

ー外に出られず取り込まれ、シートの空気溜まり部内の
空気が加温され、この加温された空気が金属蒸着層等を
加温し、輻射熱等にて車内が暖く維持されると解される
。Further, when the base film side of the laminate is set as the infrared ray irradiation side, infrared rays incident on the metal vapor deposited surface from a direction perpendicular to the surface pass through the cover. Then, most of the infrared rays reflected from the vehicle surface, etc. are cut off by the metal vapor deposition layer and are absorbed into the seat, as in the case where the seat side of the laminate is the outside. It is understood that the air in the air pocket is heated, and this heated air heats the metal vapor deposition layer, etc., and the interior of the car is kept warm by radiant heat.

りするのを防ぐことができる。In addition, in particular, when a protective cover for a vehicle is formed of a laminate in which a plastic film that has a function of cutting light in a specific wavelength range such as near ultraviolet rays is laminated on the base film, it is possible to further reduce the It can also cut light in the wavelength range, which not only prevents the protective cover from deteriorating, but also prevents the paint on the painted surface of the vehicle from deteriorating or cracking the painted surface.
