Definitions
- the invention relates to a foamable composition containing at least one polymer selected from the group consisting of polyvinyl chloride, polyvinylidene chloride, polyvinyl butyrate, polyalkyl (meth) acrylate and copolymers thereof, a foaming agent and / or foam stabilizer and di-2-ethylhexyl tereph-thalate (DEHT) as a plasticizer.
- polyvinyl chloride (PVC) is one of the most economically important polymers and is used both as rigid PVC as well as soft PVC in a variety of applications. Important applications include cable sheathing, floor coverings, wallpapers and frames for plastic windows. To increase elasticity, plasticizers are added to the PVC.
- plasticizers include, for example, phthalic acid esters such as di-2-ethylhexyl phthalate (DEHP), diisononyl phthalate (DINP) and diisodecyl phthalate (DIDP).
- DEHP di-2-ethylhexyl phthalate
- DIDP diisononyl phthalate
- DIDP diisodecyl phthalate
- terephthalic acid esters such as di-2-ethylhexyl terephthalate (DEHT) or cyclohexanoic acid esters such as diisonone-1,2-cyclohexanedicarboxylic acid ester (DINCH) have recently been discussed as possible alternatives.
- DEHT di-2-ethylhexyl terephthalate
- DICH diisonone-1,2-cyclohexanedicarboxylic acid ester
- EP 1 505 104 describes a foamable composition which contains isononyl benzoate as plasticizer.
- the use of benzoic acid isonon esters as plasticizers has the considerable disadvantage that isononyl benzoate are very volatile and therefore escape from the polymer during processing and also with increasing storage and use time. This provides considerable problems, in particular in applications, for example indoors. Therefore, in the prior art, the isononyl benzoates are frequently used as plasticizer admixtures with customary other plasticizers, for example phthalic acid esters. Isononyl benzoates are also known as
- EP 1 808 457 A1 describes the use of terephthalic acid dialkyl esters, which are characterized in that the alkyl radicals have a longest carbon chain of at least four carbon atoms and have a total number of carbon atoms per alkyl radical of five. It is stated that terephthalic acid esters having four to five C atoms in the longest carbon chain of the alcohol are well suited as PVC fast-curing plasticizers. It is also described that this was particularly surprising because prior art such terephthalic acid esters were considered incompatible with PVC. The document further states that the terephthalic acid dialkyl esters are also mixed or mechanically foamed layers or in compact layers or primers can be used. But even these plasticizers are classified as relatively volatile fast gelators, so that the above problems persist in principle.
- di-2-ethylhexyl terephthalate has been known for decades as a plasticizer for PVC and other polymers.
- Application technical data for this product are described in numerous publications, in particular in the form of conference reports and presentations.
- Don Beeler Tephthalate esters, a new class of plasticizers for poly (vinyl chloride)
- the object of the invention is to identify such plasticizers, which show even without the use of Schnellgelierern foaming properties that are equal to those of the DINP and therefore the above difficulties of faster viscosity increase of the corresponding plastisols with time (storage stability) and the clearly no longer show much higher volatility.
- these plastisols should also be readily processable, ie show a viscosity similar to that of the current standard DINP, because otherwise the viscosity of the plastisol would have to be adjusted by increased addition of thinners and then the thinner would have to be thermally expelled again during processing, which is economically and ecologically disadvantageous.
- a foamable composition containing at least one polymer selected from the group consisting of polyvinyl chloride, polyvinylidene chloride, polyvinyl butyrate, polyalkyl (meth) acrylate and copolymers thereof, a foaming agent and / or foam stabilizer and di-2-ethylhexyl terephthalate (DEHT) as plasticizers.
- polymer selected from the group consisting of polyvinyl chloride, polyvinylidene chloride, polyvinyl butyrate, polyalkyl (meth) acrylate and copolymers thereof, a foaming agent and / or foam stabilizer and di-2-ethylhexyl terephthalate (DEHT) as plasticizers.
- DEHT di-2-ethylhexyl terephthalate
- compositions containing di-2-ethylhexyl terephthalate (DEHT) and a foaming agent or foam stabilizer are suitable for the production of foams or foamed layers which exhibit significantly greater expansion behavior over corresponding DINP-containing compositions at the same temperature and residence time although the gelling speed is lowered.
- DEHT di-2-ethylhexyl terephthalate
- foaming agent or foam stabilizer are suitable for the production of foams or foamed layers which exhibit significantly greater expansion behavior over corresponding DINP-containing compositions at the same temperature and residence time although the gelling speed is lowered.
- di-2-ethylhexyl terephthalate according to the invention is significantly less volatile than isononyl benzoate used in the prior art in foamable compositions.
- the possibility of dispensing with-as a rule-volatile, fast gelators also facilitates the use for interior applications since the plasticizers of the composition according to the invention are less volatile and less readily escape from the plastic.
- At least one polymer contained in the foamable composition is selected from the group consisting of polyvinyl chloride, polyvinylidene chloride, polyvinyl butyrate, polyalkyl (meth) acrylate, and copolymers thereof.
- the polymer may be a copolymer of vinyl chloride with one or more monomers selected from the group consisting of vinylidene chloride, vinyl butyrate, methyl (meth) acrylate, ethyl (meth) acrylate or butyl (meth) acrylate.
- the amount of diisononyl-1, 2-cyclohexanedicarboxylic acid ester in the foamable composition is 5 to 150 parts by mass, preferably 10 to 100 parts by mass, more preferably 10 to 80 parts by mass and most preferably 15 to 90 parts by mass per 100 parts by mass of polymer.
- the foamable composition may optionally contain further additional plasticizers other than di-2-ethylhexyl terephthalate.
- the solvation and / or gelling ability of the additional plasticizers may in this case be higher, equal to or lower than those of the di-2-ethylhexyl terephthalates according to the invention.
- the mass ratio of the additional plasticizers used to the di-2-ethylhexyl terephthalates used according to the invention is in particular between 1:10 and 10: 1, preferably between 1:10 and 8: 1, more preferably between 1:10 and 5: 1 and in particular preferably between 1:10 and 1: 1.
- the additional plasticizers are esters of orthophthalic acid, isophthalic acid, terephthalic acid (excluding di-2-ethylhexyl terephthalate), cyclohexanedicarboxylic acid, trimellitic acid, citric acid, benzoic acid, isononanoic acid, 2-ethylhexanoic acid, Octanoic acid, 3,5,5-trimethylhexanoic acid and / or esters of butanol, pentanol, octanol, 2-ethylhexanol, isononanol, decanol, dodecanol, tridecanol, glycerol and / or isosorbide and their derivatives and mixtures.
- citric acid esters such as acetyl tributyl citrate or benzoates can be used.
- the foamable composition can be foamed chemically or mechanically.
- chemical foaming is understood to mean that the foamable composition contains a foaming agent which forms gaseous components by thermal decomposition at a higher temperature, which then cause the foaming.
- the foamable composition according to the invention contains a foaming agent.
- This foaming agent may be a gas bubble developing compound optionally containing a kicker.
- Kicker metal compounds are called, which catalyze the thermal decomposition of the gas bubbles developing component and cause the foaming agent decomposes to gas evolution and the foamable composition is foamed.
- Foaming agents are also referred to as blowing agents.
- a gas bubble-developing component a compound is preferably used, which under the influence of heat gaseous constituents disintegrate, causing the composition to expand. A typical representative of such compounds is z.
- As azodicarbonamide which releases mainly thermal decomposition N 2 and CO. The decomposition temperature of the propellant can be reduced by the kicker.
- pp '-Oxybisibenzolsulfonhydrazid Another usable propellant is called pp '-Oxybisibenzolsulfonhydrazid), also OBSH. This is characterized by a lower compared to azodicarbonamide decomposition temperature. Further information on propellants can be found in the "Handbook of Vinyl Formulating", Second Edition, John Wiley Publication (ISBN 978-0-471 -71046-2), pages 379. The most preferred blowing agent is azodicarbonamide.
- foam stabilizers are preferably used in mechanical foams.
- Commercially available foam stabilizers may be present in the composition according to the invention as foam stabilizers.
- foam stabilizers may e.g. based on silicone or soap and are used e.g. under the brand names BYK (Byk-Chemie) offered.
- the foamable compositions according to the invention can be, for example, plastisols which can be prepared by mixing emulsion or microsuspension PVC with liquid components such as plasticizers. It is further preferred that the foamable composition contains an emulsion PVC. Most preferably, the foamable composition according to the invention comprises an emulsion PVC which has a molecular weight expressed as K value (Fikent's constant) of 60 to 95 and more preferably of 65 to 90.

- Di-2-ethylhexyl terephthalate is prepared industrially either by transesterifying dimethyl terephthalate with the bulky oxo-alcohol 2-ethylhexanol or by esterifying terephthalic acid with this alcohol. Another possibility is the conversion of PET recycling material with 2-ethylhexanol. Corresponding preparation processes are described, for example, in WO 2008094396, US 2007038001 or in Huagong Jinzhan (2008), 27 (1), 143-146. For example, DEHT is commercially available from the Eastman Chemical Company under the designation Eastman 168.
- the preparation of the foamable composition according to the invention can be carried out in various ways. In general, however, the composition is prepared by intensive mixing of all components in a suitable mixing container. Here, the components are preferably added successively (see also EJ Wickson, "Handbook of PVC Formulating", John Wiley and Sons, 1993, p. 727).
- the foamable composition according to the invention can be used for the production of foamed moldings which contain at least one polymer selected from the group polyvinyl chloride or polyvinylidene chloride or copolymers thereof.
- foamed products are, for example, imitation leather, floors or wall-mounted wallpaper, in particular the use of the foamed products in cushion vinyl floors and wallpapers.
- the foamed products of the foamable composition according to the invention are prepared by first applying the foamable composition to a support or another polymer layer and foaming the composition before or after application and finally thermally processing the applied and / or foamed composition ,
- the foam in contrast to the mechanical foam, in the case of chemical foams, the foam is formed only during processing, as a rule in a gelling channel, ie, the unfoamed composition is applied to the carrier, preferably by brushing.
- a profiling of the foam can be achieved by selective application of inhibitor solutions, for example via a rotary screen printing machine. At the sites where the inhibitor solution was applied, expansion of the plastisol during processing either does not take place at all or only delayed.
- chemical foaming is used to a much greater extent than mechanical ones. For more information on chemical and mechanical foaming, see, for example, EJ Wickson, Handbook of PVC Formulating, 1993, John Wiley & Sons.
- profiling can also be achieved subsequently by means of the so-called mechanical embossing, for example by means of an embossing roller.
- the carriers can also be only temporary carriers, from which the foams produced can be removed again as foam layers.
- Such carriers may be, for example, metal bands or release paper (duplex paper).
- the final thermal processing takes place in both cases in a so-called gelation channel, usually a furnace, which is passed through by the applied on the support layer of the composition according to the invention or in which the provided with the layer carrier is briefly introduced.
- the gelling channel can be combined with a device used to produce the foam, for example, it is possible to use only one gelling channel, in which: the foam is chemically generated in the front part at a first temperature by decomposition of a gas-forming component and this foam is transferred into the semifinished product or end product in the rear part of the gelling channel at a second temperature, which is preferably higher than the first temperature It is also possible that gelation and
- Typical processing temperatures are in the range of 130 to 280 ° C, preferably in the range of 150 to 250 ° C. Gelation is preferably carried out such that the foamed composition is treated at the stated gelling temperatures for a period of 0.5 to 5 minutes, preferably for a period of 0.5 to 3 minutes. The duration of the temperature treatment can be adjusted in continuous processes by the length of the gelling channel and the speed at which the foam-containing carrier passes through it.
- Typical foaming temperatures (chemical foam) are in the range of 160 to 240 ° C, preferably 180 to 220 ° C.
- the individual layers are usually first fixed in their form by a so-called pre-gelation of the applied plastisol at a temperature which is below the decomposition temperature of the propellant, after which further layers (for example a cover layer) can be applied.
- a cover layer When all layers have been applied, gelation is carried out at a higher temperature - and, in the case of chemical foaming, also foaming. By this procedure, the desired profile can also be transferred to the cover layer.
- the foamable compositions according to the invention have the advantage over the prior art that they can be processed either at the same temperatures faster or alternatively at lower temperatures, and thus the efficiency of the production process of the PVC foams is considerably improved.
- the plasticizers used in the PVC foam are less volatile than, for example, the benzoic acid isononyl esters mentioned in the prior art, and thus the PVC foam is particularly suitable in particular for interior applications.
