た。 Conventionally, synthetic resin sheets have been used as this type of agricultural thermal insulation sheet, but synthetic resin sheets generally do not have water absorption properties, so when applied as a thermal insulation sheet for an agricultural greenhouse, for example, it can be used both indoors and outdoors. Due to the temperature difference, the indoor surface of this heat insulation sheet,
In particular, water droplets condensed on the ceiling drip downward, giving excessive moisture to the seedlings of cultivated crops, which caused the seedlings to rot.
本考案は上記の点に鑑みなされたもので、結露

である。 The present invention was developed in view of the above points, and an object of the present invention is to provide an agricultural heat-insulating sheet that can prevent water droplets from dripping due to dew condensation and thereby prevent seedlings from rotting. That is, the gist of the present invention is an agricultural heat-insulating sheet formed by laminating and integrating a polyolefin resin foam sheet having closed cells and a water-absorbing sheet made of a synthetic resin foam having open cells.
以下、本考案の一実施例を図面に基き説明す

を発揮できるからである。 The agricultural heat insulation sheet 1 is formed by laminating and integrating a polyolefin resin foam sheet 2 having closed cells and a water absorbent sheet 3 made of a synthetic resin foam having open cells. As the material for the polyolefin resin foam sheet 2, for example, polyethylene, polypropylene, ethylene-propylene copolymer, or the like can be used. Polyolefin resin is used because it has excellent weather resistance, flexibility, and strength. Further, the reason why a closed cell foam is used as the sheet 2 is that such a closed cell foam can exhibit a heat insulating and heat retaining effect.

As a means for laminating and integrating the sheets 3 and 3, for example, bonding with an adhesive may be used, or both sheets 2 and 3 may be sewn together with a thread.

過剰の水分付与による苗６の腐敗という不慮の事
態を招く危険はない。 The heat insulating sheet 1 having the above structure is applied to an agricultural greenhouse 4, for example, as shown in FIG. Reference numeral 5 denotes a plurality of support frames provided at predetermined intervals, and the heat insulating sheet 1 is stretched over these support frames 5 so that the three layers of water absorbent sheets are on the bottom surface. Here, even if dew condensation occurs on the indoor surface of the heat insulating sheet 1, especially on the ceiling 1a, due to the temperature difference between indoors and outdoors, especially at night, this water droplet will be absorbed by the three layers of the water-absorbing sheet and will drip downward. Never. Therefore, the water droplets are not dropped on the seedlings 6 of agricultural crops for cultivation, and as a result,
There is no risk of causing an unexpected situation in which the seedlings 6 rot due to excessive moisture application.
また保温シート１は独立気泡を有する発泡体シ

泡体シート２の発泡体の発泡倍率は1.5〜50倍発
泡が好ましい。 Furthermore, since the heat insulating sheet 1 has two layers of foam sheets having closed cells, it also exhibits a heat insulating and heat retaining effect and can keep the inside of the greenhouse well warm. In addition, the foaming ratio of the foam of the foam sheet 2 is preferably 1.5 to 50 times.
本考案は独立気泡を有する発泡体シート２層を
有するから、結露による水滴の発生を極力抑止で

ものである。 Since this invention has two layers of foam sheets with closed cells, it is possible to suppress the generation of water droplets due to condensation as much as possible, but even if water droplets do occur, the three layers of water-absorbing sheets will surely prevent water droplets from dripping. It is possible.

培に好適なものである。 As explained above, according to the agricultural thermal insulation sheet of the present invention, even if water droplets are formed due to dew condensation, the water droplets can be absorbed into the water absorbent sheet layer, and the water absorbent sheet is made of a synthetic resin foam having open cells. Therefore, when the heat insulating sheet is applied to an agricultural greenhouse, it can reliably prevent the water droplets from dripping, and has the effect of preventing the rotting of seedlings of cultivated crops. In addition, since it has a closed-cell foam sheet layer, it can also exhibit heat insulation and heat retention.Moreover, since the sheet of this invention is made only of synthetic resin foam, it is lightweight and can be used to insulate structures that are not very strong, such as agricultural greenhouses. It can be easily used as a sheet for agricultural purposes without reinforcing buildings, and synthetic resin foam sheets can also be configured to transmit a certain amount of light, making them suitable for growing crops. It is something.
