Abstract

The utility model relates to a thermal insulation panel for industrial and construction applications in the manufacture of packaging and internal partitions. The thermal insulating panel includes a core (3) to one side of which a sheet (2a) is bonded, wherein an outer layer (1) is bonded to the other side of the core (3) and to the sheet (2a). The core (3) is made of polystyrene, with a sheet (2c) glued to the other side of the core (3), wherein the sheets (2a) and (2c) glued to both sides of the core (3) are profiled polypropylene with grooves, and the outer layers (1) are made of cardboard. In an embodiment of the utility model, a second core (3') and a second profiled polypropylene sheet (2a') are successively bonded to the polypropylene sheet (2c). In a further embodiment of the utility model, a third core (3") and a second sheet of profiled polypropylene (2c') are additionally disposed between the second sheet of polypropylene (2a') and an outer layer of cardboard (1). The third core (3") is bonded to the second sheet of moulded polypropylene (2a') and the second sheet of moulded polypropylene (2c') is bonded to this. The thickness of the outer cardboard layers (1) is 0,5 mm, that of the cores (3, 3', 3") is 3 mm and that of the profiled polypropylene sheets (2a, 2a', 2c, 2c') is 5 mm. The grooves of the profiled polypropylene in polypropylene (2a, 2a') are arranged longitudinally and the grooves of the profiled polypropylene in polypropylene (2c, 2c') are spaced apart.

Description

The utility model relates to a thermal insulation panel and finds application in industry and construction in the production of packaging and interior partition walls.

Prior art

From US 5248534 A a panel is known which has a core composed of a mixture of plastic and filler and also a barrier layer composed of a mixture of plastic of the same type as the plastic in the core, which are bonded. Two outer layers of oleoolefin plastic such as polyethylene, polypropylene, etc. are provided.

The known packaging material can only be used for the production of packaging articles. The packaging is heavy as it is made entirely of thick plastic.

Technical nature of the utility model

The task of the utility model is to create a thermal insulation panel that is light, strong and sound and thermal insulating.

The task is solved by a thermal insulation panel, including a core, on one side of which a sheet of plastic is glued. One outer layer is glued to the other side of the core and to the plastic sheet.

According to the utility model, the core is made of polyester. A sheet of profiled polypropylene with grooves is glued to both sides of the core. One outer layer 1 made of cardboard is glued to the outer walls of the profiled polypropylene sheets.

In a variant embodiment of the utility model, a second core and a third profiled polypropylene sheet are sequentially bonded to the polypropylene sheet.

In another embodiment of the utility model, a third core and a second sheet of profiled polypropylene are further arranged between the second sheet of polypropylene and the one outer layer of cardboard. The third core is glued to the second sheet of profiled polypropylene, and to it is glued the second sheet of profiled polypropylene.

The thickness of the outer cardboard layers is 0.3 - 0.5 mm, and each of the cores is 3 - 5 mm, and each of the profiled polypropylene sheets is 4 - 5 mm.

The thermal insulation panel can be used both for building internal partitions and for making packaging.

The combination of polyester and profiled polypropylene when making the panel reduces its weight. Thanks to the profiled polypropylene, which has longitudinal and transverse air channels, the strength qualities of the panel are improved and good sound insulation is guaranteed, and the use of polystyrene further increases the thermal insulation qualities.

Explanation of the attached figures

The utility model is illustrated by the attached figures, of which:

Figure 1 - represents a section of the main version of the thermal insulation panel.

Figure 2 - represents a section of a second version of the thermal insulation panel with two cores and three sheets of profiled polypropylene.

Figure 3 - represents a section of another variant, in which the thermal insulation panel has three cores and four sheets of profiled polypropylene.

Examples of implementation of the utility model

As can be seen from the attached figures, the thermal insulation panel is constructed from a core 3 made of polystyrene. On both sides of the core 3 is glued one sheet of profiled polypropylene with channels 2a and 2c. To the outer walls of the profiled polypropylene sheets 2a and 2c. is glued to one outer layer 1 made of cardboard. In a variant embodiment of the utility model, a second core 3' and a second sheet of profiled polypropylene 2a' are successively glued to the profiled polypropylene sheet 2c.

In another embodiment of the useful model, between the second sheet of polypropylene 2a' and one outer layer of cardboard 1, a third core 3 and a second sheet of profiled polypropylene 2c' are additionally located. The third core 3 is glued to the second sheet of profiled polypropylene 2a', and to it is glued the second sheet of profiled polypropylene 2c'.

The thickness of the outer cardboard layers 1 is 0.5 mm, of the core 3, 3', 3 is 3 mm, and of the profiled polypropylene sheets 2a, 2a', 2c, 2c' is 5 mm.

The channels of the profiled polypropylene for sheets 2a and 2a' are located longitudinally on the thermal insulation panel, and for sheets 2c and 2c' - transversely.

Application of the utility model

When the panel is intended for the production of packaging products, the variant of figure 1 is used, since it is thinner and can be easily bent. For this purpose, the set dimensions of the package and the places of bending are outlined on the panel. The panel is placed on a crimping machine and then bent to obtain the desired package.

When the panel is used for the production of partition internal walls, a variant from figure 2 or figure 3 is chosen with inserted more sheets of polyester and profiled polypropylene. The panel is mounted on a pre-built metal, wooden or PVC frame which is fixed to the floor and ceiling of a room.

Polyester and profiled polypropylene, which has longitudinal air channels, guarantee good sound insulation and thermal insulation of the panel.
