Definitions
- the invention relates to a method for producing a sound and / or
- Prior art insulating elements for sound and / or thermal insulation of buildings can be made of a variety of insulation materials. However, especially frequently, especially in the area of facades, insulating elements made of polystyrene particle foam are used. Because these not only have good insulation values, but are also relatively inexpensive to produce. The good insulation values are primarily attributable to the air-filled pores or cells that occur during the
- Foaming of the polystyrene particles are formed.
- other polymers are suitable for the formation of insulating materials, provided that their particles are foamable.
- the total pore volume or total cell volume also includes a gob volume remaining between the particles, which may vary in size depending on the degree of welding and / or the degree of compaction of the starting materials.
- a gob volume remaining between the particles which may vary in size depending on the degree of welding and / or the degree of compaction of the starting materials.
- From EP 2 527 124 AI go by way of example a shaped body for sound and / or thermal insulation of buildings and a method for producing such a shaped body. In the method, prefoamed polystyrene particles are welded and / or compacted under the action of pressure and / or heat, so that an existing from the interstices between the particles,
- Contiguous cavity volume is retained in the molding. Due to the coherent cavity volume of the molded body is able to absorb water vapor and water and immediately return.
- the proposed for sound and / or thermal insulation of buildings moldings is therefore used in particular as a drainage plate.
- Shaped body is lowered.
- EP 2 527 124 AI is also proposed to coat the polystyrene particles before welding and / or compacting with a binder.
- the composite of the polystyrene particles with one another is then primarily effected by the binder applied externally to the particles, which is preferably an organic binder.
- the bond caused by the binder should in particular increase the mechanical stability of the molding.
- Polystyrene particles less water repellent or even attracts water.
- a three-dimensional reticular structure forms, which pervades the entire shaped body, penetrating moisture is held by the binder in the interior of the molding. As a result, the thermal insulation performance is reduced.
- polymer particles are known which, unlike
- Polystyrene particles do not behave water repellent. These include in particular particles of biopolymers.
- Biopolymers may be composed of natural polymers such as polylactic acid or cellulose derivatives. Furthermore, they can be prepared from artificially prepared monomers, in their preparation, in turn, natural raw materials are used. As an example, polyethylene may be cited as long as the ethylene used is made from natural organic waste material. Biopolymers can therefore also be polymers of biogenic origin. Furthermore, one can speak of biopolymers, when the polymers are naturally biodegradable.
- biopolymers are used in the present case, these are understood in particular to be polar, hydrophilic polymers which are composed of polar, hydrophilic monomers.
- Polymer particle foams produced from biopolymers are prone to increased water absorption, so that they are used to form a sound and / or sound
- Measures are taken that protect the sound and / or thermal insulation element from increased water absorption.
- EP 2 366 847 A1 discloses an insulating and drainage plate made of foamed polymer particles which have been bonded together with the aid of a binder. In this way, between the particles gussets remain, which form a coherent reticulated void volume, is drained by gravity driven water. To remove the To support moisture inside the plate, the proposed in this document plate has a tapered free end, which comes to rest on attachment of the plate to a building exterior wall and the moisture leads funnel-like to the center of the plate. Furthermore, a subsequent
- the present invention has the object to provide a sound and / or thermal insulation element made of a polymer particle foam, which has good insulation values and also a low water absorbency. Furthermore, the sound and / or
- Heat insulation element to be simple and inexpensive to manufacture.
- Heat-insulating elements are used foamable and / or prefoamed polymer particles.
- the foamable and / or prefoamed polymer particles are coated with a binder and then a
- Shaping process in which the polymer particles are glued together and / or sintered.
- the bonding is effected by means of the binder.
- a non-hydrophilic binder is used to coat the foamable and / or prefoamed polymer particles.
- the non-hydrophilic binder leads to the formation of a coating enveloping the polymer particles, which not only serves to bond the polymer particles, but also reduces the hydrophilicity of the sound and / or thermal insulation element produced by the method. This means that a sound and / or thermal insulation element produced by the process according to the invention has a lower water absorption capacity.
- non-hydrophilic binder therefore makes subsequent impregnation of the sound and / or thermal insulation element to reduce the hydrophilicity dispensable. This means that the production of a sound and / or thermal insulation element with reduced water absorption capacity is simplified by the method according to the invention. This also has a cost-reducing, since not only eliminates a further step, but replaced the non-hydrophilic binder at the same time the impregnating agent.
- a produced by the process according to the invention sound and / or
- Thermal insulation element is thus particularly suitable for use in outdoor areas and / or in particularly moisture-contaminated areas. Furthermore, it is suitable for use as a drainage element or plate.
- the non-hydrophilic binder is an organic polymer binder.
- Such has a high binding force, so that a stable composite of the polymer particles is achieved with each other.
- the hydrophilicity of an organic polymer binder is largely determined by: - the polarity of the monomers
- additives are added to the binder to form the coating, for example, to improve the processability of the binder, the type and amount of the additives also play a role.
- hydrophilicity of the binder must be determined experimentally and / or determined by other factors or parameters.
- the contact angle (KW) of water and diiodomethane on the binder surface can be tentatively determined. From the
- OFE Oberfikieenenergy
- PA additive additive
- DA non-polar disperse fraction
- the pure binder in a wet layer thickness of 250 ⁇ m is knife-coated onto a Lenetta film.
- the contact angle of a water droplet after a minute Aquilibr michszeit on the surface of the binder layer with a Krüss Mobile Drop GH11 is measured.
- Binder layer determined. Subsequently, the surface energy in accordance with DIN 55660-2 (December 2011), the method according to Owens, Wendt, Rabel and Kaeble (OWRK) and the polar component and the disperse component are determined. If the binder is a dispersion powder, this is previously redispersed with water, so that the polymer solids content is 50 wt .-%.
- a binder is used which has a static initial contact angle of water after equilibrating for 1 min> 35 °, preferably> 40 °, more preferably> 50 °.
- Method may alternatively or additionally based on the surface energy of the
- Bindeffen be determined.
- a binder which has a surface energy ⁇ 70 mN / m, preferably ⁇ 65 ° mN / m, more preferably ⁇ 60 mN / m.
- the surface energy should be above 30 mN / m.
- ⁇ 25 mN / m It should preferably not fall below a value of 1 mN / m.
- a binder which has a disperse fraction of the surface energy> 10 mN / m, preferably> 20 mN / m, more preferably> 30 mN / m.
- the disperse fraction of the surface energy should not exceed 60 mN / m.
- the ratio DA / PA is preferably> 1.0, preferably> 1.4, more preferably> 1.6.
- the ratio PA / OFE is preferably ⁇ 0.50, preferably ⁇ 0.45, more preferably ⁇ 0.40.
- a "non-hydrophilic" binder in the context of the present application is preferably understood as meaning an organic polymer binder on the surface of which contact angles> 35 ° are formed with water whose surface has an OFE ⁇ 70 mN / m, the polar portion of the OFE ⁇ 35 mN / m and the disperse portion of the OFE> 30 mN / m.
- an aqueous polymer dispersion based on acrylate, (meth) acrylate, styrene acrylate, vinyl acetate, vinyl acetate-ethylene, vinyl esters, vinyl chloride, polyurethane, polysiloxanes and / or silicone resins is used as binder.
- This has the advantage that it covers the polymer particles when coating so that an approximately uniform distribution of the binder is ensured.
- the adhesion of the binder to the polymer particles can be improved by the use of an aqueous polymer dispersion.
- a dry can also be used
- Dispersion powder based on acrylate, styrene acrylate, vinyl acetate, vinyl acetate-ethylene and / or vinyl chloride can be used as a binder.
- the adhesion of the dry dispersion powder to the polymer particles can be improved by pre-moistening the particles and / or by using prefoamed polymer particles which still have a residual moisture content.
- Polyethylene terephthalate can be used. These polymers have monomers which are non-polar and therefore absorb very little water or are water-repellent. This applies correspondingly to polymer particle foams produced therefrom.
- a non-hydrophilic binder By the coating proposed according to the invention with a non-hydrophilic binder, the low water absorption capacity of such a polymer particle foam can be obtained or even further reduced.
- foamable and / or prefoamed polymer particles of a biopolymer may also be used. It is preferably in the
- biopolymers unlike the polymers mentioned above, consist of polar monomers. Accordingly, polymer particle foams produced therefrom have increased water wettability and water absorption capacity.
- Water absorption capacity can be reduced.
- the dual function of the non-hydrophilic binder as an adhesive and as an impregnating agent is particularly useful when using biopolymers. Because biopolymers usually combined worse than the other polymers mentioned above. Thus, an additional bonding of the particles is essential if a stable composite of the particles is to be achieved.
- the insulation elements thus achieve sufficiently good thermal insulation values.
- the amount of binder content contributes to the fact that the sound and / or thermal insulation element produced by the method according to the invention has a high mechanical stability.
- the starting materials for producing a sound and / or thermal insulation element conventional additives may be added.
- the proportion of the additives is preferably 0 to 40 wt .-%, preferably 0 to 30 wt .-%, further preferably 0 to 20 wt .-% based on the total solids weight of the starting materials.
- the flame retardant used is preferably an intumescent flame retardant, preferably expandable graphite.
- Expanded graphite is usually present in the form of coarse and / or angular particles, which ensure a good toothing with the polystyrene particles.
- the addition of expandable graphite as a flame retardant therefore has no negative impact on the stability of the composite of the polymer particles with one another.
- expandable graphite - in contrast to most conventional flame retardants - toxicologically harmless.
- the addition of the flame retardant can be carried out in such a way that the polymer particles are additionally coated with the flame retardant before they are subjected to the shaping process.
- Flame retardant can, before, during or after coating with the
- Binder done.
- the flame retardant can be added to the binder, so that the polymer particles can be coated in only one coating operation with the flame retardant and the binder.
- the coated polymer particles are preferably introduced into a mold and adhesively bonded and / or sintered with the addition of pressure and / or heat.
- the pressure and / or temperature conditions during mixing the size of the interstices remaining between the polymer particles can be controlled. Depending on the respective degree of compression and / or on the expansion of the polymer particles can therefore a sound and / or
- Heat insulation element are produced, which also has a drainage function.
- An expansion-limiting effect is furthermore achieved via the binder, which deposits on the polymer particles during sintering as a binder film and thus counteracts expansion of the particles. The extent of expansion is therefore controllable via the binder content.
- a sound and / or thermal insulation element made of a polymer particle foam is further proposed, which comprises bonded together and / or sintered polymer particles, wherein the bonding - if provided - is effected by means of a binder with which the Polymer particles, preferably before the United, have been coated.
- the binder is non-hydrophilic and forms a coating which at least partially envelops the polymer particles.
- the polymer particles substantially completely enveloping coating is achieved.
- hydrophilic binder thus has a dual function, namely that of an adhesive and that of an impregnating agent.
- the coating with the non-hydrophilic binder causes the following
- the specified sound and / or thermal insulation element is therefore suitable
- Drainage element or plate can be used.
- Non-hydrophilic in the sense of the present application in particular, a binder is considered that meets at least one of the following parameters, based on the contact angle of water and / or on the
- the binder which forms the coating preferably has a static initial contact angle of water after equilibrating for 1 min> 35 °, preferably> 40 °, more preferably> 50 °.
- a binder may be non-hydrophilic in the sense of the present invention
- the binder forming the coating preferably has a polar fraction of the surface energy ⁇ 35 mN / m, preferably ⁇ 30 mN / m, more preferably ⁇ 25 mN / m.
- the binder forming the coating has a disperse fraction of the surface energy> 10 mN / m, preferably> 20 mN / m, more preferably> 30 mN / m.
- the coating is preferably formed by a binder based on acrylate, (meth) acrylate, styrene acrylate, vinyl acetate, vinyl acetate-ethylene, vinyl esters, vinyl chloride, polyurethane, polysiloxanes and / or silicone resins. Whether this is actually a non-hydrophilic binder must, if necessary, be determined experimentally beforehand if the abovementioned parameters are not known. This can be done as described previously in connection with the method according to the invention.
- the polymer particle foam preferably contains polymer particles of polystyrene, polyurethane, polypropylene, polyethylene and / or polyethylene terephthalate. These polymers have monomers that are nonpolar and therefore inherently water repellent.
- Binder this property can be obtained or even increased. Furthermore, an active water absorption by capillary effects can be counteracted, for example, the drainage effect of the sound and / or
- polymer particle foam polymer particles from a
- Biopolymer in particular from polylactide and / or from a biopolymer based on starch or cellulose, for example cellulose acetate, cellulose propionate and / or cellulose butyrate. Monomers of these biopolymers are naturally polar and polymers themselves are then relatively polar. A sound and / or thermal insulation element produced therefrom accordingly has a comparatively good water wettability or high water absorption capacity.
