Definitions

  • the present invention relates to the insulation of aluminum sections or frames for doors and windows and more particularly the insulation of the spaces between the interior and exterior sections of a frame.
  • Breaking the thermal bridge by lacing is an insulation technique used on aluminum openings and frames to increase the insulation performance of this type of frame.
  • the principle is simple: a material that is not very thermally conductive (that is to say much less thermally conductive than aluminium) is crimped between the interior and exterior aluminum profiles of the sash and the frame to reduce the reciprocal exchanges of temperature between the interior to the exterior of the building or vice versa.
  • the strips are generally plastic profiles with an elongated cross section and having at each end of this section a mechanical fixing system complementary to a fixing system provided on the internal faces of the inner and outer sections, for example a fixing to dovetail.
  • the interior and exterior aluminum profiles assembled by these strips form a composite profile, also called a frame, thus generally comprising one or more cavities between the two profiles, hereinafter called a bar cavity(ies).
  • a composite profile also called a frame
  • bar cavity(ies) the cavities between the two profiles
  • air convection and/or radiation can negatively influence the insulation performance of the assembly. It is the same in the case of the cavity of barring where the convection of the air and/or especially the radiation between the internal faces of the external and internal profiles increase the flow of energy and thus the losses of energy through the chassis.
  • the bar cavity is at least partially filled with a foamed polymer material.
  • the filling of the cavity of the strapping cannot be coextruded with the profile (as for example in EP 2 501 530 A1 ), but must be done at the time of lacing or after, i.e. during or after the assembly of the two internal and external profiles by means of bars.
  • a polymer foam profile of appropriate section is inserted either by being fixed beforehand to one of the bars (filling during assembly) or even simply by sliding a polymer foam profile into the cavity by one of the ends. of the assembled frame (filling after assembly).
  • Powder coating is a process used to paint profiles in a durable way. Once the profiles have been stripped, cleaned of impurities and pre-treated to ensure perfect adhesion of the lacquer, a paint powder, for example a polyester paint powder, is applied to them via electrostatic powdering, depositing colored particles. In an oven heated to around 200°C, the polymerization then hardens everything to stabilize the chosen coating.
  • the anodizing operation which is an operation not involving high temperatures like powder coating, consists in producing a thin layer of aluminum oxide (alumina) resistant to surface of a profile, which can affect its decorative appearance. It is carried out through oxidation controlled by chemical or electrolytic colorations.
  • the parts to be anodized are immersed in several successive baths, which first ensure the preparation of the surface of the profile or the frame, then the production of the alumina with, if desired, the deposit of a appearance and color and, finally, the stabilization of the alumina layer by a so-called “sealing" operation consisting in hydrating the alumina layer in order to obtain good corrosion resistance.
  • EP 2 799 654 A1 discloses a method for insulating a barrette cavity of an aluminum frame for the opening or frame of a door or window.
  • EP 2 799 654 A1 also discloses a device for isolating a barrette cavity of an aluminum frame for the opening or frame of a door or window.
  • An object of the present invention is therefore to provide a polymeric foam profile of suitable cross-section to insulate an aluminum profile cavity and preferably a lattice cavity by reducing energy losses by convection and/or radiation, which can be used in profiles or frames intended for powder coating.
  • step (b') anodization comprising the immersion of the aluminum profile or the aluminum frame in several successive baths ensuring the preparation of the surface of the profile or the frame, the production of alumina on the said surfaces, optionally with the deposition of a appearance and/or color and stabilization of the alumina layer by a sealing operation.
  • the method comprising steps (a) and (b), further comprises, before or after step (a), a step (x) of spraying a paint powder, for example polyester , preferably by electrostatic powdering, on the outer faces of the aluminum profile or the aluminum frame, the polyester paint powder melting in step (b) to form a protective coating (powder coated).
  • a process comprising steps (a), (x) and (b) is therefore a powder coating process as described above.
  • a device for insulating a cavity of an aluminum profile or of a barrette cavity of an aluminum frame for the opening or frame of a door or window comprising a body foamed with a first polymer composition of polygonal cross-section provided on at least one surface, preferably on (each of) two opposite surfaces with one or more foamed or unfoamed fins of a second polymer composition, in which the foamed body of the first polymer composition comprises a foam based on polyesters, preferably of the polyalkylene terephthalate type, such as for example polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polybutylene naphthalate (PEN), polytrimethylene terephthalate (PTT), etc
  • the problem of insulating a cavity is twofold: on the one hand the foam inside the cavity must cover the entire distance between the bars to be able to guarantee the absence of convection and/or radiation between the two internal faces of the two external and internal profiles, and, in the case of powder coating, it must remain intact even after a heating procedure without the strips softened by the heat of powder coating do not deform. Note that in the case of additional anodizing, it will prevent the retention of liquids from successive baths by capillarity, i.e. it must allow the flow and correct rinsing of the surfaces of the profile or frame.
  • the first polymer composition comprises (co)polyesters having good rigidity even at the high temperatures of a powder coating.
  • the inventors have found that by proceeding in this way, the forces exerted by the foam subjected to thermal expansion is likely to deform the strips.
  • the trend is to improve the insulation performance of strips by making them less dense (by foaming for example) and/or thinner, which further increases the risk of deformation during powder coating.
  • the inventors have found that the foam can shrink (at least partially) during cooling to room temperature after heating or powder coating and thus again free up part of the distance between the bars and therefore reduce the insulation performance. of the chassis.
  • the inventors then designed the insulation devices according to the invention by slightly reducing the initial size of the foam body with respect to the distance between two strips and by providing at least on one side of the fins which at the temperature of heating or thermolacquering will soften or melt, will be crushed by the thermally expanding foam, above all, will solidify later (at a lower temperature) than the foam of the body and will thus not only fill in any shrinkage space, even if necessary glue the foam body to the bars.
  • Such bonding depending on the choice of the nature of the second polymer composition, is moreover particularly advantageous, because it makes it possible to increase not only the insulation performance, but also the mechanical rigidity of the assembly.
  • the inventors have determined that in certain variants, for the isolation device to be particularly suitable in an isolation process comprising steps (a) and (b) or steps (a), (x) and (b), it is preferable to choose the second polymer composition preferably from polymer compositions capable of softening or melting at a temperature below a temperature between 180 and 250°C.
  • an isolation device can also be useful in an isolation process comprising steps (a) and (b) or steps (a), (x) and (b), even if the softening or melting temperature of the second composition is only slightly lower, or even identical to that of the first composition, that is to say of the foamed body.
  • the fins being located closer to the surfaces of the profile, they tend to heat up more quickly than the foamed body. It is to highlight that in these cases, the heating step must however be controlled more precisely both in terms of temperature and in terms of heating time.
  • the inventors have determined that it would also possibly be advantageous to provide a foam which, beyond a certain temperature, would be subjected not only to thermal expansion, but also to a new additional foaming, even more important than the thermal expansion, so as to fill said cavity to the maximum, that is to say by means of a post-foaming.
  • the fins provided according to the invention play the role of spacer elements which make it possible to maintain the surface or surfaces of the foam body at a certain distance from the corresponding surfaces of the profile or frame, preferably at a distance of 4 to 8 mm, preferably 5 to 6 mm, so as to ensure the normal flow (without capillarity effect) of the liquids of the treatment baths.
  • the inventors have further determined that it is not essential, in order to avoid losses by convection and/or radiation, that the opposite sides of an insulation device according to the invention cover the entire distance between the corresponding surfaces of the profile or frame (i.e. the isolation device must be in contact on two opposite sides with the profile or frame), but a gap of up to approximately 2 to 3 mm, preferably up to 'at about 1 to 2 mm, does not significantly decrease the insulation performance. Indeed, it has been found that a slot of such small width does not allow significant convection through the slot (and therefore significant heat loss). This is also true for radiation losses which are extremely low and therefore negligible under these conditions.
  • an isolation device according to the invention can be chosen to be up to 3 mm, preferably up to 1 to 2 mm below those of the cavity without reducing the insulation performance, even in the case of an anodizing process without an additional foam expansion step.
  • a particular advantage is that the isolation device is all the easier to insert into said cavity.
  • the fins can be of generally any cross-section, preferably polygonal in shape and particularly preferably of roughly triangular or trapezoidal section.
  • the number of fins per side of the foam body will be chosen appropriately, in particular according to the dimensions of the cavity to be insulated, and will often be between 1 and 10, preferably between 2 and 5.
  • the insertion of the isolation device in step (a) can be done in any suitable way.
  • the insulation device is inserted into the bar cavity after the sections have been assembled into a frame by introducing it through one end of the frame.
  • the isolation device is inserted with one of the strips at the time of assembly.
  • the fixing of the insulation device on the bar is done for example by gluing, welding, coextrusion, etc.
  • the fins are at least on the side opposite the side fixed to the bar and possibly on other sides, but not on the side fixed to the bar. In this context, it should be noted that the side fixed to the strip effectively prevents the capillary effect in the event of anodization.
  • the insulation method according to the invention is used for the insulation of a barrette cavity of an aluminum frame.
  • the fins or at least part of them are located facing a bar, either in direct contact, or at a very small distance of less than 3 mm, or even less than 2 mm.
  • the first polymer composition is preferably a composition comprising (co)polyesters, in particular PET, PBT, PTT, PEN, etc. .., or mixtures thereof, as sole polymers or optionally in combination with other (co)polymers, such as impact modifier polymers known for (co)polyesters, ethylene copolymers, such as ethylene-vinyl acetate (EVA) copolymers, ethylene-methyl acrylate (EMA) copolymers , ethylene-ethyl acrylate (EEA) copolymers, ethylene-butyl acrylate (EBA) copolymers, ethylene copolymers modified with groups such as, for example, maleic anhydride or glycidyl methacrylate, etc., thermoplastic elastomers (TPE), such as thermoplastic elastomers polyesters (TPC), thermoplastic elastomeric olefins unvulcanized (TPE), such as thermoplastic elastomers polyesters (TPC),
  • the second polymer composition comprises one or more polymers chosen from cross-linked polyethylene, copolymers of ethylene modified or not by groups such as for example maleic anhydride, thermoplastic elastomers (TPE, such as TPS, TPU, TPC, TPV, TPO), (co)polyesters (PET, PBT, PTT, PEN, ...) and is optionally foamed.
  • TPE thermoplastic elastomers
  • the densities of the fins will generally be greater than 25 kg/m 3 , preferably between 100 kg/m 3 and the non-foamed density of the second polymer composition.
  • the first polymer composition that is to say the foamed body
  • the second polymer composition that is to say the fins
  • chemical post-foaming in the case of chemical foaming agents is done by the additional volume of gas generated by the decomposition of the chemical foaming agent, the gas initially contained in the cells and the gas generated during heating at higher temperature being further simultaneously subjected to thermal expansion.
  • the first polymer composition and/or the second polymer composition can comprise, as sole foaming agent or in addition to other physical and/or chemical foaming agents commonly used for foaming such compositions, an amount between 0.001 and 5% by weight, preferably between 0.01 and 3% by weight, in particular from 0.1 to 2% by weight of at least one physical foaming agent that is liquid at room temperature (and at atmospheric pressure), preferably chosen from alkanes having a boiling point above 25°C, in particular n-pentane, isopentane or cyclopentane, hexanes (all isomers), heptanes, etc., or among ethanol, dimethyl ether, etc., or mixtures thereof.
  • foaming agents in the first and/or second polymer composition will cause post-foaming inside the cavity during heating or powder coating.
  • the phenomenon responsible for the so-called physical post-foaming in the case of liquid physical foaming agents at ambient temperatures results not only from the liquefaction then the re-evaporation of the initial physical foaming agent, but results from a combination with the phenomenon of gas exchange through the cell walls. This phenomenon is well known in the field and is the reason why the gas initially responsible for the foaming will generally be gradually exchanged with atmospheric air.
  • the so-called physical post-foaming described here takes advantage of the air permeability and the liquefaction of agents that are normally liquid at room temperature, which means that the entry of air into the cells is increased by reducing the volume of the agent. of foam becoming liquefied on cooling. After a certain time, the cells therefore not only contain the amount of foaming agent initial (whose volume is reduced by its change of state), but also a large quantity of air. If such a foam is then heated, its volume will correspondingly increase further, when the liquid foaming agent evaporates again.
  • the foaming agents that can be used for the initial foaming of the first and/or second polymer compositions can be physical or chemical foaming agents or a combination of these two types.
  • Physical foaming agents such as in particular molecular nitrogen, carbon dioxide, linear or branched C 1 to C 4 alkanes, are in the form of gases under normal temperature and pressure conditions. These gases or liquids are soluble in the polymer compositions melted at high temperature and under high pressure and form a single phase under the appropriate pressure and temperature conditions. By depressurizing the monophasic system, the nucleation and growth of gas bubbles that have become insoluble generate a cellular structure.
  • the foaming agent or agents are preferably chosen from propane, isobutane, n-butane and/or carbon dioxide.
  • Chemical foaming agents decompose under the effect of a rise in temperature. They can be classified into two families: exothermic chemical foaming agents, such as azodicarbonamide, OxydiBenzeneSulfonyl Hydrazide, etc. which decompose producing heat. For example, azodicarbonamide decomposes around 210°C (see above if its decomposition is not desired during initial foaming), but in the presence of a suitable decomposition accelerator, such as zinc oxide and /or zinc stearate, the decomposition temperature can be lowered by about 60°C. Endothermic chemical foaming agents decompose by absorbing heat. For example, citric acid, baking soda and their mixtures decompose between 150 and 230°C and generally produce less gas volume per gram of chemical foaming agents than exothermic chemical foaming agents.

  • the aluminum profiles or aluminum frames have been subjected to powder coating and optionally to anodization after the insertion of the insulation device into at least one of the cavities of the profile or frame.
  • the cavity provided with an insulation device according to the invention is a cavity for baring a chassis.
  • the invention envisages in yet another aspect the use of an insulation device according to the invention for the insulation of cavities in aluminum profiles or in the bar cavities of an aluminum frame to improve their performance. insulation.
  • a barrette cavity is the cavity formed when two profiles (generally one intended to be located outside and one intended to be located inside a building) are attached by means of barrettes in order to avoid a bridge heat between the two profiles.
  • a bar cavity is therefore generally of polygonal section, often roughly rectangular, delimited on the one hand by two bars and on the other hand by the internal faces (facing each other) of the two profiles.
  • the strips that can be used for the stripping of two profiles to form a frame are those generally used in the field, preferably they are made of polyamide, in particular polyamide 6.6, a mixture composed of poly(phenylene oxide) and polystyrene (PS/PPO ), for example Noryl, dense or foamed, optionally reinforced with glass fibers, and they have a generally essentially linear central section comprising at each end a partial section allowing mechanical fastening with a corresponding section provided on the profiles, for example a section called dovetail or similar. It should be noted that the strips may have a more complex cross-section, but they nevertheless always comprise at least two mechanical fastening regions for joining (at least) two sections.
