Definitions
- porous membranes of such blends are described, for example, in EP 0 764 461.
- Such membranes are made by casting from an aqueous polymer composition.
- Foams made of PPSU or PES are known in principle, although not in mixture with each other. So in L. Sorrentino were: "Polymeric foams from high-performance
- Blends containing either PPSU or PSE are known as it were, though information in the art is rare. So both polymers are especially as in the Quantity of subordinate components, eg described in PS foams, in order to influence the properties in these commodity materials. Foams containing PPSU or PES as the main component are only to be found in a few descriptions, such as the following:
- WO 2015/097058 describes foams based on PPSU or PES containing at least 10% by weight of a polyolefin.
- the phase-separating polyolefin acts primarily as a nucleating agent. In this case, more uniform pores are achieved, but without the flame retardancy or mechanical properties, such as
- Temperatures good mechanical properties, in particular with respect to the elongation at break and have a sufficient for many applications in the field of vehicle and aircraft at least sufficient flame retardancy.
- the foam should be used in an application range of up to 120 ° C, preferably up to 150 ° C ambient temperature even over long periods.
- the foam should be realized from the composition to be developed by a variety of methods and with a wide range of shapes.
- this composition has 0.5 to 10% by weight of a blowing agent.
- the composition consists of 90 to 95% by weight of a mixture of PES and PPSU in a ratio between 1 to 1 and 8 to 1, 1 to 9% by weight of a blowing agent and 1 to 5% by weight of additives.
- the additives may in particular be flame retardant additives, plasticizers, pigments, UV stabilizers, nucleating agents, impact modifiers, adhesion promoters, rheology modifiers, chain extenders, fibers and / or nanoparticles.
- phosphorus compounds in particular phosphates, phosphines or phosphites are used.
- Suitable UV stabilizers or UV absorbers are generally known to the person skilled in the art.
- HALS compounds Tiuvine or triazoles.
- the impact modifiers used are generally polymer particles comprising an elastomer or soft phase. These are often core (shell) shell particles, with an outer shell that is as a maximum weakly crosslinked and as a pure polymer would have at least minimal miscibility with the blend of PES and PPSU.
- all known pigments can be used as pigments.
- the influence on the foaming process - as with all other additives used in larger amounts of more than 0.1% by weight - should be investigated. This is feasible for the skilled person with relatively little effort.
- the fibers are usually known fiber materials, the one
- the nanoparticles which can be present, for example, as tubes, flakes, rods, spheres or in other known forms, are generally inorganic materials. These can take on different functions in the finished foam. Thus, these particles partially act as nucleating agents during foaming. Furthermore, the particles can influence the mechanical properties as well as the (gas) diffusion properties of the foam. Furthermore, the particles additionally contribute to the low flammability.
- phase-separating polymers can also be added as nucleating agents.
- the polymers described are separated from the others in the consideration of the composition
- Nucleating agents as these primarily affect the mechanical properties of the foam, the melt viscosity of the composition and thus the
- the chemical blowing agents are less or non-volatile substances that are chemically decomposed under the foaming conditions and thereby form the actual blowing agent.
- a very simple example of this is tert-butanol, which is under
- Foaming conditions isobutene and water forms.
- Further examples are NaHCO 3, citric acid or their derivatives, azodicarbonamide (ADC) or compounds thereof,
- TSH Toluenesulfonylhydrazine
- OBSH oxybis (benzosulfohydrozide)
- 5-phenyltetrazole 5-PT
- foams prepared from the compositions of the invention are also part of the present invention.
- a method for foaming the compositions of the invention is part of the present invention.
- the composition is foamed at a temperature between 150 and 250 ° C and a pressure between 0.1 and 2 bar.
- the foaming takes place at a temperature between 180 and 230 ° C in a
- Polymer compositions are known, in particular with respect to methods for
- thermoplastic foams are applicable to the present composition. However, there are some particularly preferred alternatives.
- a composition still without leavening, in an autoclave at a temperature between 20 and 120 ° C and a pressure between 30 and 100 bar applied to the propellant and then by lowering the pressure and raising the temperature to the foaming temperature foamed in an autoclave.
- the composition charged with the blowing agent is cooled in an autoclave and removed after cooling. This composition can then be foamed later by heating to the foaming temperature. This can also be done, for example, with further shaping or in conjunction with other elements such as inserts or cover layers.
- the composition containing the blowing agent is heated in an extruder.
- the composition is heated without leavening agent in an extruder and charged with the blowing agent, preferably with CO 2 and / or N 2 in the extruder.
- the composition can be discharged from the extruder by means of a slot die or other shaping nozzle and thereby foamed.
- This variant can, for example, with a direct subsequent coextrusion or lamination can be combined in such a way that cover layers are applied directly to a foam sheet or foil formed from a slot die.
- the composition is foamed on exiting the extruder and thereby by means of a granulator
- the granulator is mounted so close to the exit point of the nozzle that the already separated particles foam immediately after formation.
- Composition are discharged at the exit from the extruder in a foam injection device. In this device is then foamed directly under shaping.
- a fourth alternative embodiment is characterized in that the composition is discharged on exiting an extruder in an underwater granulator, wherein in this such a combination of temperature and pressure is present that foaming is prevented.
- the resulting, propellant loaded granules can then later - for example, thermally - foamed.
- the foams according to the invention or the foams produced by the process according to the invention can be used in a variety of ways. Preference is given to
- Foams in the vehicle such. used in the construction of road, rail, water, space or aircraft. Due to the heavy flammability foams of the invention can be installed in particular in the interior of these vehicles. Further applications are found, for example, in the electrical industry, in the construction of wind turbines or in mechanical engineering.
- the foams according to the invention preferably have a degree of foaming which constitutes a reduction of the density in relation to the pure blend of between 1 and 98%, preferably between 50 and 97%, particularly preferably between 70 and 95%.
- the foam has a density between 20 and 1000 kg / m 3 , preferably 40 and 250 kg / m 3 .
