Definitions

  • the present invention relates to a profile designed to be integrated in a composite thermal break system.
  • the present invention also relates to a composite thermal break system and a method for obtaining it.
  • Thermal break systems which are normally used to minimise heat loss between two environments.
  • Thermal break systems are, for example, used in door and window frames.
  • Such thermal break systems comprise:
  • the thermally conductive elements are normally made of aluminium (for example, they are an integral part of the door or window frame), whilst the heat insulating bars are made of polyamide.
  • the technical purpose which forms the basis of the present invention is to propose a profile designed to be integrated in a composite thermal break system which optimises the thermal insulation between a hotter environment and a colder environment.
  • the present invention may also have for an aim to provide a profile designed to be integrated in a composite thermal break system which can improve structural strength.
  • Another aim of the present invention is to provide a composite thermal break system designed to comprise the profile.
  • Yet another aim of the present invention is to provide a method for making a composite thermal break system.
  • the numeral 1 denotes a profile designed to be integrated in a composite thermal break system 10.
  • the profile 1 comprises a support 2 and a first thermally expandable element 3 connected to the support 2.
  • the support 2 stably supports the first thermally expandable element 3.
  • the first thermally expandable element 3 is connected to at least one surface 20 of the support 2.
  • the support 2 comprises or coincides with a first heat insulating bar 21 suitable for being interposed between two thermally conductive elements of the composite system 10.
  • the first bar 21 extends mainly longitudinally (see example in Figure 1 ).
  • references to the bar 21 (or another element) being heat insulating mean that it is made of a material (or a combination of materials) which does not allow good heat conduction (for example, rubber, plastic materials, etc.).
  • the first bar 21 is made of polyamide.
  • the first thermally expandable element 3 extends mainly longitudinally. The first thermally expandable element 3 is applied to the first bar 21 in such a way that its longitudinal main direction of extension is parallel with the longitudinal main direction of extension of the first bar 21.
  • the first thermally expandable element 3 is glued to the first bar 21. This may be done using an adhesive interposed between the first thermally expandable element 3 and the first bar 21.
  • a double-sided adhesive material preferably in the form of a double-sided adhesive strip.
  • one surface of the strip is connected to the first bar 21 and the other surface of the strip is connected to the first thermally expandable element 3.
  • the first thermally expandable element 3 is at least partly housed in a groove in the first bar 21. This allows (or at least contributes to) a stable connection between the first thermally expandable element 3 and the first bar 21.
  • an edge of the first thermally expandable element 3, when inserted in a groove in the first bar 21, could be coupled to the latter.
  • the first thermally expandable element 3 adopts an expanded configuration (see Figure 3 ) which is substantially maintained even after any cooling which may occur.
  • the predetermined heating involves heating at a temperature greater than 170°C. This is important because the first thermally expandable element 3 is normally obtained by means of hot extrusion at around 120°C and the process for extrusion and forming of the first thermally expandable element 3 must not cause the expansion (except to a very limited and negligible degree).
  • the predetermined heating is drawn out over several minutes (advantageously at least 10 minutes, preferably around 20 minutes).
  • the first thermally expandable element 3 comprises PVC and a foaming substance (for example, it may comprise only those two components).
  • the quantity of foaming substance present, by weight, is between 0.2% and 2%, preferably between 0.4% and 1.5%.
  • the foaming substance comprises or coincides with 4,4'-oxybis(benzene sulfonyl hydrazide).
  • the first thermally expandable element 3 has a specific weight of around 1.2 g/cm 3 , ultimate tensile strength of 15 N/mm 2 and ultimate elongation of 350%.
  • the present invention also relates to a composite thermal break system 10 comprising at least:
  • the two thermally conductive profiles 4a, 4b are made of metal material, advantageously aluminium.
  • they are part of a door or window frame.
  • the composite system 10 also comprises a second heat insulating bar 22 interposed between the two thermally conductive profiles 4a, 4b.
  • the first thermally expandable element 3 of the first profile 6 is interposed between the support 2 of the first profile 6 and the second bar 22.
  • the first thermally expandable element 3 is inside a compartment 5 formed by the combination of the support 2, the second bar 22 and at least one portion of each of the two thermally conductive profiles 4a, 4b.
  • the volume of the first thermally expandable element 3 increases.
  • the first thermally expandable element 3 occupies at least two thirds of the compartment 5 (preferably it almost completely occupies the compartment 5).
  • the composite system 10 comprises a second thermally expandable element 220 which is connected to the second bar 22 and which is located inside the compartment 5.
  • the second thermally expandable element 220 is interposed between the first thermally expandable element 3 and the second bar 22.
  • the second thermally expandable element 220 is applied to the second bar 22 in such a way that its longitudinal main direction of extension is parallel with the longitudinal main direction of extension of the second bar 22.
  • the second thermally expandable element 220 is stably connected to the second bar 22, for example by gluing, or by coupling means.
  • the second thermally expandable element 220 may be connected to the second bar 22 by a double-sided adhesive strip.
  • the second thermally expandable element 220 could be at least partly inside a groove in the second bar 22 (embodiment not illustrated).
  • the groove would allow the second thermally expandable element 220 to be coupled to the second bar 22.
  • the second thermally expandable element 220 is made of the same material as the first thermally expandable element 3.
  • the second thermally expandable element 220 comprises PVC and a foaming substance (for example, it comprises only those two components).
  • the quantity of foaming substance present, by weight, is between 0.2% and 2%, preferably between 0.4% and 1.5%.
  • the foaming substance comprises or coincides with 4,4'-oxybis(benzene sulfonyl hydrazide).
  • the second thermally expandable element 220 has a specific weight of around 1.2 g/cm 3 , ultimate tensile strength of 15 N/mm 2 and ultimate elongation of 350%.
  • the first and second thermally expandable elements 3, 220 change configuration, passing from a first, non-expanded configuration (see Figure 1 or 2 ) to a second, expanded configuration (see Figure 3 ).
  • first, non-expanded configuration the first and second thermally expandable elements 3, 220 are spaced from each other, whilst in the second, expanded configuration the first and second thermally expandable elements 3, 220 are in contact with each other.
  • first and second thermally expandable elements 3, 220 create a barrier which is interposed between the first and the second thermally conductive profiles 4a, 4b.
  • the Applicant has shown through experimentation that the composite system 10 has better thermal insulation than the situation in which there is only air inside the compartment 5. Moreover, in the expanded configuration the stiffness of the composite thermal break system 10 is also improved compared with the situation in which there is only air in the compartment 5. It is important that even in the non-expanded configuration the first and second heat insulating elements 3, 220 are connected respectively to a corresponding wall of the compartment 5 to prevent them from coming off during the movement and to prevent positioning errors immediately before expansion.
  • the first and second thermally expandable elements 3, 220 only make contact with each other after heating at a temperature greater than 170°C.
  • the volume of the first and/or the second thermally expandable element 3, 220 increases by at least 20% compared with the initial volume, preferably increasing its volume by between 30% and 50% compared with the initial volume.
  • the same effect could also be achieved using only the first thermally expandable element 3.
  • the first thermally expandable element 3 in the expanded configuration would advantageously make contact with the second bar 22. In this way, a barrier would still be obtained between the first and the second thermally conductive profiles 4a, 4b.
  • the support 2 to which the first thermally expandable element 3 is applied could coincide with the first thermally conductive profile 4a.
  • the second thermally expandable element 220 (if present) could be applied to the second thermally conductive profile 4b.
  • said embodiment means that assembly of the composite thermal break system 10 is more complex.
  • the present invention also relates to a method for making a composite thermal break system 10 comprising the following steps:
  • the step of positioning a first heat insulating profile 6 between two thermally conductive profiles 4a, 4b involves inserting the first heat insulating profile 6 in corresponding grooves 8a, 8b in the two thermally conductive profiles 4a, 4b.
  • at least one shaped portion 9a, 9b of the first heat insulating profile 6 is inserted in at least one element shaped to match it which is formed by the grooves 8a, 8b made in the thermally conductive profiles 4a, 4b.
  • the shaped portion 9a, 9b of the heat insulating profile 6 is made in the first bar 21.
  • the first thermally expandable element 3 is connected to the first bar 21 before positioning the first heat insulating profile 6 between the two thermally conductive profiles 4a, 4b. In this way, the operation to insert the first bar 21 in the two thermally conductive profiles 4a, 4b can be carried out extremely rapidly and using machines known to experts in the field and normally used for that operation.
  • the element shaped to match, formed by the grooves 8a, 8b in the thermally conductive profiles is clamped on the corresponding shaped portion 9a, 9b of the first heat insulating profile 6.
  • the step of positioning a second heat insulating profile 7 between the two thermally conductive profiles 4a, 4b involves inserting the second heat insulating profile 7 in corresponding grooves 8c, 8d in the two thermally conductive profiles 4a, 4b.
  • at least one shaped portion 9c, 9d of the second heat insulating profile 7 is inserted in at least one element shaped to match it which is formed by the grooves 8c, 8d made in the thermally conductive profiles 4a, 4b.
  • the element shaped to match, formed by the grooves 8c, 8d in the thermally conductive profiles is clamped on the corresponding shaped portion 9c, 9d of the second heat insulating profile 7.
  • the second heat insulating profile 7 comprises a second heat insulating bar 22 and a second thermally expandable element 220 connected to the second bar 22.
  • the second thermally expandable element 220 is connected to the second bar 22 before positioning the second heat insulating profile 7 between the two thermally conductive profiles 4a, 4b.
  • the step of heating the first thermally expandable element 3 also causes heating and expansion of the second thermally expandable element 220. Said expansion of the second thermally expandable element 220 takes place inside the compartment 5.
  • the step of heating the first and second thermally expandable elements 3, 220 causes them to expand in such a way that they make contact with each other.
  • the step of heating the first thermally expandable element 3 comes after the step of positioning the first and second heat insulating profiles 6, 7 between the two thermally conductive profiles 4a, 4b.
  • the first and second thermally expandable elements 3, 220 are not in contact with each other. This facilitates positioning of the first and second heat insulating profiles 6, 7 relative to the two thermally conductive profiles 4a, 4b.
  • the first and second thermally expandable elements 3, 220 do not make contact with each other during positioning of the first and second heat insulating profiles 6, 7 relative to the first and second thermally conductive profiles 4a, 4b.
  • the step of heating the first thermally expandable element 3 takes place in an oven.
  • Said step involves in particular heating the composite thermal break system 10 in an oven.
  • this involves heating the composite system 10 in an oven at a temperature greater than 170°C (preferably at a temperature of between 180°C and 200°C), advantageously for a period of between 10 and 25 minutes.
  • the step of heating the first thermally expandable element 3 takes place at least partly simultaneously with the painting operation (this operation is always necessary and usually involves heating the composite thermal break system 10 in an oven at a temperature greater than 180°C).
  • the painting operation is normally carried out in a painting oven by means of polymerisation of the paint powders previously applied on at least part of the thermally conductive profiles. In this way, during painting, expansion of the first and second thermally expandable elements 3, 220 is also achieved (optimising the steps in the method).
  • the invention brings important advantages. First, it allows improved thermal insulation in a composite thermal break system. At the same time it allows the prevention of an increase in assembly times for a composite thermal break system. Moreover, it allows the use of common machines and equipment currently used for assembling a composite thermal break system.
