Abstract
The utility model discloses an inflation and thermal insulation plastic film which is used for covering a thermal insulation shed, laying ground film, etc; a double-layer film whose middle part can be inflated is used by the utility model, the space between the two films are divided into air chambers by a partition, and each air chamber is provided with an air charging nozzle; an air layer which does not flow and is no good at heat conduction is formed between the two films, so the thermal insulation is good.
Description
The utility model relates to a kind of insulation material that adopts plastics to make, especially a kind of aeration insulating plastic sheeting.
In background technology, be commonly used in when plastic sheeting serves as insulation material and cover plastic, thermal-insulation booth, spreading breeding, resident family's door and window winter protection, its deficiency is that plastic sheeting often uses for individual layer, inner and outside only depend on a film every, be easy to heat exchange, cause this kind film heat-insulating property poor, during in the winter time as heat preservation greenhouse, the straw screen or mat of having to add a cover thereon is to improve insulation.
The utility model purpose is to provide a kind of aeration insulating plastic sheeting that can improve heat-insulating property at above-mentioned deficiency.
Technical solution of the present utility model is achieved in that the aeration insulating plastic sheeting adopts middle inflatable duplicature, be divided into each air chamber with cutting off between two films, charge into an amount of air when having charging connector to use on the air chamber, can form certain thickness face.
Advantage of the present utility model and good effect are: 1. good heat insulating.Be bad at the air layer of heat conduction again because of between two films, forming not flow, hindered the heat exchange of inside and outside gas, reach the raising insulation effect.2. photosynthesis is good.The hot house that adopts the present invention to make can be cancelled straw screen or mat, makes the booth light application time long, abundance.3. simplify big booth structure, improve service life.Adopt the inflation double-decker, strengthened the whole tensile strength of film, can reduce a boron steel frame.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model first example structure sketch,
Fig. 2 is the utility model second example structure sketch.
Referring to Fig. 1, the aeration insulating plastic sheeting is a double-decker, is divided into film 1, following film 2.The partition of being made by film 3 is bonded between two films and along the width of film and in a row arranges spaced reciprocally, as cuts off 3, cuts off 3
1, cut off 3
2, forming a plurality of air chambers 4, each air chamber 4 can seal alone, on each air chamber 4 charging connector 5 is arranged all, also can be several air chamber 4 intercommunications, a shared charging connector 5, the height of partition 3 is generally between 20-60cm.The film limit 7 that protrude on the film both sides is used between the film and connects.
Referring to Fig. 2, cutting off 6 is in a row two moulds to be closed spaced reciprocally along the film width to form, to simplify processing technology.
But the supply of this film rolling makes things convenient for severing, the time spent inflation, and laying connected with each other has heat insulation effect preferably, energy savings.
Claims (4)
1. an aeration insulating plastic sheeting is characterized in that adopting middle inflatable duplicature, is divided into each air chamber with cutting off between two films, and charging connector is arranged on the air chamber.
2. according to the described aeration insulating plastic sheeting of claim 1, it is characterized in that cutting off is in a row to arrange spaced reciprocally along the film width between two films.
3. according to the described aeration insulating plastic sheeting of claim 1, it is characterized in that cutting off is in a row two moulds to be closed spaced reciprocally along the film width to form.
4. according to claim 2 or 3 described aeration insulating plastic sheetings, it is characterized in that there is the film limit of protrusion on the film both sides.
