Definitions

  • the present invention relates to a thermal insulation element for use in a thermal break door or window.
  • thermal break or “thermal barrier” refers to an element with low thermal conductivity arranged in an “assembly” in order to reduce or prevent the flow of thermal energy between conductive materials.
  • the metallic material which is most used in this sector is aluminum, owing to a series of advantages which characterize it such as workability, lifetime, robustness, no maintenance.
  • Aluminum is an optimum thermal conductor, transfers the temperature from the internal environment to the external environment and vice versa. This effect is commonly called “thermal bridge”, meaning for example that part of the heat produced by the heating plant will be lost.
  • an insulating material which forms an active part of the structure of the aluminum profile is usually inserted.
  • the thermal insulation element of the invention is of the type consisting of an aluminum profile which has internally profiles (of various cross-sections) made of synthetic material with a low thermal conductivity. Basically the two aluminum components are mechanically joined together by the said low-conductivity profiles and these interrupt the conductivity of the aluminum structures.
  • This assembled composition is defined as "thermal break” because the thermal conductivity and associated heat flow of the aluminum is blocked by the thermal insulating material with a lower thermal conductivity.
  • the profile which has the task of acting as a "thermal barrier” must have a low thermal conductivity and therefore first and foremost the material which forms it must be an insulating material. The more insulating it is the better will be the performance of the door or window in terms of comfort and energy consumption.
  • the thermal insulation is obtained by means of low thermal conductivity profiles, the insulating materials forming these profiles must have intrinsic properties which make them suitable for the application. They must have mechanical, thermal, chemical and physical properties which make them suitable for use in combination with aluminum. The use, for these applications, of synthetic materials such as those belonging to the family of thermoplastics has for some time been well-established.
  • the synthetic profiles used as thermal breakers in different forms, cross-sections and in various solutions are composed of nylon 6-6 reinforced with glass fiber, modified polyphenylene oxide (MPPO) reinforced with glass fiber (Noryl®), ABS, PP, PVC resins.
  • MPPO modified polyphenylene oxide
  • Noryl® modified polyphenylene oxide
  • ABS polypropylene
  • PP polypropylene
  • PVC resins polyvinylene resins
  • the low thermal conductivity polymeric materials used as thermal break profiles may be mounted/assembled with the aluminum parts both before and after painting of the door or window.
  • the painting cycle with epoxy paint or polyester paint applied electrostatically is on average between 180-200 degrees for periods from 15 to 20 minutes. It can be deduced that if it is desired to use a profile made of insulating material to be assembled before painting, i.e. on untreated aluminum, it must withstand the complete painting cycle and in particular the high painting temperatures. Choosing this manufacturing process, some of the insulating polymeric materials which cannot withstand the painting temperatures are automatically destined to be assembled, possessing good insulating properties, on already painted aluminum profiles.
  • the thermal break profiles composed of nylon 6.6 reinforced with glass fibers polyphenylene oxide + polyamide reinforced with glass fibers optimally withstand the painting temperatures and therefore may be mounted on untreated aluminum profiles, while other polymers, such as ABS, PVC, PP are assembled after the painting cycle.
  • other polymers such as ABS, PVC, PP
  • thermal conductivity which is a characteristic peculiar to each polymer.
  • ⁇ glass fiber 1 W/m°K, as opposed to a ⁇ of 0.25 W/m°K for a polymer.

  • the element object of the present invention prepared from a thermoplastic polyester based thermal insulating material, which presents with a particular performance in terms of thermal conductivity, mechanical, thermal and chemical properties which satisfy the requirements stipulated by the specifications for the thermal break doors and windows proposed.
  • a thermal insulation element which withstands the painting temperatures and which has low thermal conductivity values.
  • the said thermal insulating material may contain polymer alloys with PET and mixtures of reinforcing agents on their own or mixed with glass fiber.
  • the present invention provides a thermal insulation element for use in a thermal break door or window, characterized in that it comprises a thermoplastic polyester based thermal insulating material.
  • said thermoplastic polyester is selected from PET, PBT, PEN, PCT, PTT and mixtures thereof.
  • said thermoplastic polyester is amorphous.
  • said thermal insulating material further comprises glass fiber.
  • said thermal insulating material comprises less than 25% by weight of glass fiber.
  • said thermal insulating material comprises about 15% by weight of glass fiber.
  • said thermal insulating material further comprises at least one nucleating agent.
  • said at least one nucleating agent is selected from the group consisting of metallic stearates, olefinic type nucleating agents, waxes, olefins containing inorganic fillers, inorganic nucleating agents, ionomers and partially salified acids.
  • said thermal insulating material further comprises nanofillers.
  • said nanofillers are selected from hollow glass spheres, zirconium phosphate, nanometric metal phosphates and salts thereof, clays and halloysite.
  • said thermal insulating material comprises up to 7% by weight of said nanofillers.
  • said thermal insulating material comprises up to 5% by weight of said nanofillers.
  • said thermal insulating material comprises from 0.1 % to 5% by weight of said nanofillers.

  • Fig. 2 shows a storage modulus vs. temperature graph.
  • the thermal insulation element according to the invention is of the type consisting of an aluminum profile 1 which has internally profiles 2, 3 (with various cross- sections) made of synthetic material having a low thermal conductivity.
  • the two aluminum components 4,5 are mechanically joined together by the said low-conductivity profiles 2,3 and these interrupt the conductivity of the aluminum structures.
  • PET is a polyester derived from the reaction of terephthalic acid and ethylene glycol and has the following properties:
  • an amorphous state or a crystalline state is obtained.
  • an amorphous state of the polymer is obtained, distinguished by a certain degree of transparency since the molecules of the polymer do not have the necessary time to rearrange themselves randomly in an ordered state such as the crystalline state.
  • a so-called crystalline state is obtained, i.e. wherein the molecules are arranged in an orderly fashion in space, forming a well-defined and ordered structure.
  • the product is crystalline, it assumes an off-white color, unlike the amorphous which is transparent.
  • the two possible structures have, associated with them, a series of properties which are more or less pronounced.
  • a PET obtained from bottles has a very high amorphous component and therefore a slow crystallization and hence solidification speed; if it were to be used for molding, for example, the molding cycles would be extremely long and uneconomical.
  • the amorphous product does not have as good a performance as the product in its crystalline state.
  • the PET in its crystalline state, the PET assumes higher elastic modulus values, a greater temperature resistance and chemical resistance such that it may be used in various industrial sectors. More specifically, non-modified grades of PET obtained from bottles soften at 80°C with the result that the polymer may not be used as such in so-called engineering applications.
  • PET In order to be able to use PET in durable high-performance articles the material must be highly crystalline and must also be reinforced with glass fiber (GF) or mineral fillers or reinforcing agents in general.
  • GF glass fiber
  • Glass- reinforced PET with a high % of crystallinity has good mechanical characteristics, a low creep with a thermal expansion coefficient similar to that of aluminum (a quality which, for example, materials without glass fiber do not have, even though they offer better thermal insulation).
  • PET is a semi-crystalline polymer which, depending on the manufacturing condition, has a structure which is amorphous, crystalline and semi-crystalline. A high crystallinity is desirable in articles/products which require stability at high temperature and dimensional stability and strength.
  • the crystallinity must be induced by means of crystallization produced by chemical agents (not only technologically with controlled cooling) and precisely controlled so as to obtain the desired properties. Therefore with the use of special chemical additives called nucleating agents, in combination with the conversion and cooling conditions, the desired crystallinity levels and therefore desired performance values are obtained.
  • the thermal conductivity is the ratio under stationary conditions between the heat flow and the temperature gradient which causes the passage of the heat.
  • the thermal conductivity is a measurement of the aptitude of a substance to transmit heat, i.e. the greater the ⁇ value the less insulating is the material. It depends only on the nature of the material, not on its form.
  • the crystallinity greatly influences the thermal conductivity (for example amorphous PMMA / PS: 0.2 W/m°K; crystalline HDPE: 0,5 W/m°K).
  • V average speed of the phonon
  • L is a very small constant (a few Angstroms) owing to the phonon scattering among the numerous defects which therefore produces a low ⁇ .
  • the conductivity is also dependent on the temperature: in an amorphous polymer it increases with an increase of the temperature towards the Tg, while it decreases above the Tg.
  • PE, PS, PTFE, EPOX some amorphous semi-crystalline polymers
  • Virgin PET is semi-crystalline (unlike that obtained from bottles which is amorphous)however, depending on its thermal history, it may be amorphous, or semi-crystalline or crystalline.
  • the semi-crystalline material may have an appearance which is transparent (particle dimensions ⁇ 500 nm) or opaque and white (particle dimensions of up to a few microns) depending on the crystals structure.
  • the maximum value of the crystallinity is about 60%.
  • An amorphous product may be produced by rapid cooling of the melted polymer below the Tg; in this way the molecules of the polymer do not have enough time to position themselves in an orderly manner and therefore form crystalline zones (if the polymer is heated again above the Tg so that the chains are also free to move, the first crystals start to form and then grow). This method is called "solid-state crystallization”.
  • the melted polymer is cooled slowly it forms a more crystalline material.
  • This material if crystallized from an amorphous solid, has spherulites which contain many small crystallites, instead of containing a "single large crystal" (which would result in greater conductivity).
  • the conditions favorable for crystallization occur in fact between about 85°C (slightly higher than the value of Tg) up to 250°C (slightly below the complete melting temperature). At the bottom end of this temperature range the crystallization speed which is initially very slow increases gradually until it becomes elevated between 140°C and 180°C.
  • PET has generally a thermal conductivity of between 0.15 and 0.24 W/m°K.
  • heat conduction means the transmission of a vibration quantized in the form of a "phonon" on a crystal lattice (in physics a phonon is a “quasi particle” which describes a vibration "quantum” in a rigid crystal lattice.
  • the phonon is the mechanical vibration "quantum” of the material means which transmits sounds and heat.
  • Semi-crystalline polymers are also poorly efficient heat conductors because the presence of an amorphous phase inside them reduces the transmission of the phonon.
  • the main components are:
  • a percentage of glass fiber from 22% to 30% applied to a polymer of the prior art such as polyamide 6.6 is sufficient to provide an elastic modulus, a tensile strength, a temperature resistance (High Distortion Temperature HDT, Vicat) and a coefficient of linear thermal expansion (CLTE) having a value suitable for the required application.
  • ABS without GF 0.14 it can be immediately noted how the GF component plays a major part in defining the thermal conductivity value since 30% of 1 .01 (0.303) is much greater than 60% of 0.25 (0.175).
  • Step 1 a Polyester / Nylon 6.6 polymeric alloys
  • HDT Heat Distortion Temperature - measurements
  • mechanical values measured of the tensile elastic modulus, tensile strength measurements
  • DMTA Dynamic Mechanical Thermal Analysis - measurements
  • Step 4 Verification of the possible reduction/replacement of the glass fiber with other components (nanofillers, hollow glass spheres, tubular halloysite, phenolic hollow spheres, aramidic fibers, etc.)
  • Step 5 Reduction of the thermal conductivity by means of creation of insulating cells (with % CBA) using expandable spheres
  • Step 6 Polyester based blends Step 1 Description of the material
  • polyester indicated in the present description is PET, even though it is to be understood that the invention is not limited to this polymer, but embraces all thermoplastic polyesters, of which PET is an example.
  • PET compared to Nylon 6.6 has a very low water absorption (measured, for example, according to the Standard ASTM D570).
  • ASTM D570 Standard ASTM D570
  • the water absorbed by the polyamide has a "plasticizing" effect on the product which manifests itself with a reduction in the mechanical properties (reduction of the tensile strength modulus, increase of the resilience); also with GF reinforced polyamide the phenomenon occurs, so that the values of the properties diminish from the moment the article is produced until the moment it reaches the water absorption equilibrium.
  • Step 2 Formulative research to obtain thermal and mechanical values
  • thermal resistance of the thermal insulating material increases. It can also be noted that:
  • the modulus also increases with an increase in the glass fibers.
  • the nucleating agents used in the invention are substantially polyester crystallization promoters. Among these the following are mentioned: - metallic stearates (for example calcium stearate, etc.);
  • - inorganic fillers such as talc
  • Nylon 6.6 25% GF such as Licomont® by Clariant®
  • - inorganic nucleating agents for example ionomers with a high molecular weight such as Surlyn® by DuPont®.
  • the formulations with nucleating agent have HDT values which are way higher, but not yet comparable with those which normally distinguish the formulations suitable for withstanding the painting cycles, having maximum values of more than 230°C Vicat (10N).
  • test-pieces for DMTA analysis using the "three point bending" approach were obtained from the profiles extruded with the blend PET 0088B.
  • the method chosen allows the variations of flexural elastic modulus against temperature to be determined. It is therefore possible to compare the PET based composition with the material forming the thermal break profiles used in nearly all of them by thermal break window manufacturers, namely Nylon 6.6 with 25% GF.
  • Fig. 2 shows a storage modulus [MPa] vs. temperature T° [°C] graph.
  • the graph in Figure 2 shows six curves, identified respectively by the letters A, B, C. D, E and F and briefly described below.
  • Curve A Storage modulus ( ⁇ ') vs. T° of PET 0088B;
  • Curve B Loss modulus (E) vs. T° of PET 0088B;
  • Curve C Glass transition (Tg) vs. T° of PET 0088B;
  • Curve D Storage modulus ( ⁇ ') vs. T° of Nylon 66 25% GF
  • Curve F Glass transition (Tg) vs. T° of Nylon 66 25% FG
  • the composition PET 0088B has a behavior equivalent to that of Nylon 66 25% GF in the temperatures range considered (up to 220°C), while in the range between room temperature and 90°C (temperature range present during normal use of a thermal break door or window), the mechanical rigidity properties are superior. This data is important because it means that, in the case of fatigue stresses over time affecting the thermal break door or window, the PET solution offers a more significant basic resistance than Nylon 66 25% GF.
  • the tested compositions were both molded and extruded and, in the case of determination of the thermal conductivity, molded test-pieces were used; the instrument used for determination of the thermal conductivity was the C_THERM TCi (Thermal Conductivity Analyzer) manufactured by C_Therm Technologies which allows the thermal conductivity to be measured over small areas, in the region of 17 mm and greater. It was possible to compile a series of tables which illustrate in a more detailed manner the relationship between the compositions of the raw material (various additives) and the morphology of the said composition modified by the transformation and thermal conductivity parameters.
  • C_THERM TCi Thermal Conductivity Analyzer
  • a PET without GF the formulation of which following molding and "conditioning" at 140°C provides a (maximum) crystallinity of 35%, was examined by varying the mold cooling conditions (times and temperatures) so as to obtain variable crystallinity conditions to which a thermal conductivity value may be assigned.
  • the data shown in the table below was obtained:
  • Step 4 Modification of the polymeric composition with nanofillers
  • the "critical" additive for the purposes of reducing the thermal conductivity is, as seen above, glass fiber.
  • Nano-like fillers may be natural or synthetic and are characterized by very small dimensions. From 1 mm to 1 pm they may already be called nano particles, but more frequently nano particles have a size ranging from 1 to 100 nm. What makes nanoparticles unique is their high surface area/volume ratio.
  • the filler with the best performance is the zirconium phosphate based nanofiller ZrP04.
  • the table below shows the data of different nanofillers tested.
  • PET0094 and PET 0102 produce an increase of the modulus and the breaking load. Moreover the E-modulus obtained is greater than that of Nylon 66 25 GF in its natural state, in equilibrium with the moisture and equivalent to that of Nylon 66 25 GF in the DAM condition. Formulations with 1 % to 5% by weight of nanofillers are preferred.
  • PET 0094 has a very good performance in terms of its temperature resistance, despite having a GF content of 15%, since it contains the nanofiller
  • test-pieces in Table 24A were then examined for their thermal conductivity properties again using the C-Therm instrument
  • Step 5 Reduction of the thermal conductivity by means of expansion
  • the formulation PET 0094 was extruded with the addition of "expandable spheres" using a specially modified extrusion apparatus. The results are shown in the table below.
  • the GF is reduced from the 25% of Nylon 6.6 to the 15% of PET+GF+nanofillers+nucleating agents+expandable spheres
  • the PET has a thermal conductivity reduced from 0.34 W/m°K to 0.2 W/m°K
  • the Vicat temperature (thermal properties) is higher than 230°C
  • the elastic modulus E (mechanical properties) is greater than 3000 MPa.
  • the reduction of the GF% with the introduction of special nanofillers and therefore the further reduction of the thermal conductivity coefficient may be adopted also with blends of thermoplastic polyesters according to the invention, namely with the specific addition of polymers which are compatible with the polyesters or made compatible with the adoption of specific compatibility agents.
  • Polymeric bases with improved thermal conductivity or with improved mechanical/thermal performances compared to the basic characteristics for example of PET are thus obtained.
  • NY 66 Poly(hexamethylene adipamide), for example Durethan® or Zytel®
  • NY6 Polyamide 6, for example Ultramid® or Techyl®
  • PC Polycarbonate, for example MacroLan® or Lexan®
  • PEI Polyetherimide, for example Ultem®
  • PPO/PPE Modified Polyphenylene Oxide, for example Noryl® or Vestoran®
  • ABS Acrilonitrile butadiene styrene, for example Novodur® or Magnum® Sincral®
  • PS Polystyrene, for example Edistir® or Styron®, SPS (Syndiotactic Polystyrene, for example Xarec®
  • PCT polycyclohexylene dimethylene terephthalate, for example Termx® PCT
  • PEN polyethylene-naphthalate, such as Teonex®
  • PES Polyether
  • the preferred alloy or composition is that consisting of PET and NY 66.
  • the studies carried out show that there is an important synergic action between the two materials. In fact, when mixing PET with NY 66 in all the proportions, namely with both a greater proportion of PET and a greater proportion of NY66, the following may be noted:
  • NY66 helps increase the speed of crystallization of the system, making the blend easier to mold and/or extrude.
  • PET has the lowest value for the degree of crystallization
  • NY66 has the highest value.
  • the glass fibers act as nucleating agents for crystallization of the polymer. This effect is more significant for PET GF which has a low crystallization speed and this addition of NY66 to the PET makes the latter much easier to extrude than in the case of 100% PET which would require many more additives to make it easily extrudable (workable).
  • the 100% PET and/or PET/NY66 alloy and/or the other alloys mentioned may be mixed not only with nanofillers but also with other natural or synthetic fillers which have a value of ⁇ 1 W/m°K (this being the thermal conductivity of the glass fibers normally used in the thermoplastic compounds for this application).
  • the various reinforcing fillers hollow glass spheres (which contain air which has a ⁇ value of 0.024 W/m°K), generally with an aminosilane primer, are preferred, ensuring on the surface a solid "bridge" with the polymer in which they are immersed.
  • tubular halloysite which has a ⁇ value of 0.095 W/m°K and may be mixed with the PET polymer or its alloys preferably in its version with primer which ensures solid adhesion to the polymer matrix.
  • the GF, nanofillers and expansion system with suitable expansion agents may be present in these compositions. All these solutions result in a lowering of the initial thermal conductivity level associated with the base polymer which is to be used.
  • the density may not be reduced by very much as in the case of purely insulating and non-structural materials.
