Description

  The present invention relates to a heat insulating sheet suitable for use in vinyl sheets and summer curing sheets used in agriculture, and relates to a heat insulating sheet that may be used in cold protection equipment, cold protection articles, and the like.

  Conventionally, when synthetic resin materials, rubber materials, or sheet-like materials such as non-woven fabric, paper, cloth, etc. are in a thin state of 0.1 mm to 0.05 mm, cold air below 0 degrees cannot be insulated and conveys cold air. It was.

  Vinyl sheets and non-woven sheets used in agriculture and horticulture should be very thin sheets of 0.1mm to 0.05mm in order to reduce the burden on handling and crops even for cold protection. I am using it. However, because this sheet is thin, it conveys cold air and sometimes crops cannot be shipped due to cold damage, snow or frost.

  The curing sheet is also a thin sheet like the agricultural sheet, and has no heat insulation function, so the outside temperature is transmitted inside the sheet.

  On the other hand, in the case of conventional work clothes in winter, it is difficult to move due to blistering, such as using bulky materials such as cotton and feathers for heat insulation and cold insulation.

  A large number of foam beads are attached to one side of the flexible sheet in close or close proximity. Adhesive is applied to one side of the flexible sheet without the foam beads, and release paper is adhered to the adhesive side. Characteristic heat insulation sheet.

  It becomes a heat insulation sheet by attaching foam beads having a heat insulation effect to the flexible sheet, and since it is a foam bead, it is flexible and does not restrict the properties of the flexible sheet. Furthermore, it is a heat-insulating sheet that is easy to handle without imposing a heavy burden because it is light and foamy beads like air.

  It is a heat insulating sheet that can prevent the peeling and peeling of the foamed beads that are likely to occur when the single-sided beads are adhered by interposing the foamed beads between the two flexible sheets, and can maintain strength and heat retention.

  Double-sided tape with so-called foam beads attached, with foam beads attached to one side of the flexible sheet, adhesive or adhesive attached to the other side, and release paper attached to this adhesive surface It is a heat insulation sheet that can be used as a cold protection product by eliminating the waste by using only the necessary amount in a proper place.

  The outer diameter of the foam beads used in this heat insulation sheet is from about 1 mm for close adhesion, but when using close adhesion, the size of up to 4 mm should be used to achieve both daylighting on the agricultural sheet and heat insulation. Can do.

  This heat insulating sheet uses the heat insulating function of the foam beads, and if used for a curing sheet in summer, the temperature rise in the sheet can be prevented.

  If this heat insulating sheet is used in greenhouse house cultivation, the temperature drop in the room can be prevented, so the heating cost can be reduced.

  As shown in FIG. 1, in a state where a large number of foam beads 2 are adhered in close proximity or close to one surface of the flexible sheet 1, the foam beads are used toward the cold protection purpose side. Mainly used for agricultural vinyl sheets, glass greenhouse houses, curing sheets, sheets covering the whole fruit tree, perches for packing frozen products, etc. The size of foam beads is about 1 to 2 mm. It can also be used as carpet underlay as a flooring insulation and anti-slip tool.

  In FIG. 2, a large number of foam beads 2 are adhered to both surfaces of the flexible sheet 1 in close proximity or close to each other in the same manner as in the first embodiment to block the minus temperature and measure the heat retention. Mainly used for agricultural vinyl sheets, anti-slip carpets, and insoles for work shoes. The foam beads are about 1 to 3 mm in size. In addition, when using it as an underlay mat for floor mats, use a size of about 4 mm.

  In FIG. 3, a large number of foam beads 2 are interposed between two flexible sheets 1 and attached to both flexible sheets in close proximity or close to each other. It is mainly used for agricultural vinyl sheets and glass greenhouse houses, and foam beads are used for lighting and heat insulation by changing the size from about 1 mm to 4 mm. In addition, about 1 mm size is used for applications such as disposable sanitary gloves.

  In FIG. 4, an adhesive is attached to one side of the flexible sheet 1 shown in FIG. 1 without the foam beads 2, and a release paper is attached to the adhesive surface. Attached to the fingertips of disposable sanitary gloves and the necessary parts for cold protection purposes. In addition, products that are used by pasting on conventional products that are on the market include arm covers, waterproof apron, etc., and foam beads are about 1 to 2 mm in size.

  In FIG. 5, foam beads 2 of up to 4 mm are attached to the flexible sheet 1 in close proximity. Used mainly when lighting is required with vinyl sheets in agriculture.

  The main products that can be used as cold protection and cold protection products by processing the insulation sheet shown in Fig. 1 are arm covers, leg warmers, waterproof apron, windbreakers, rain gappers, snow mountain climbing tents, fruit protection bags, slippers, and disposable embossed gloves. The foamed beads used are about 1 to 2 mm.

These are figures which show Example 1 of this invention, and are sectional drawings which adhered many foam beads to the flexible sheet single side | surface. These are the figures which show Example 2 similarly, and are sectional drawings which made many foam beads adhere closely to both surfaces of a flexible sheet. These are the figures which similarly show Example 3, and are sectional drawings which pinched many foam beads between two flexible sheets. FIG. 9 is a view similarly showing Example 4, in which a large number of foam beads are closely attached to one side of a flexible sheet, an adhesive is attached to one side, and a release paper is attached. . These are the figures which show Example 5 similarly, and are sectional drawings which made the bead of a size up to 4 mm adhere to the single side | surface of the flexible sheet | seat close.
