- the weight fraction of adhesion promoters on the grafted matrix polymer is 0.3 to 20%, preferably 3 to 10%.
- Fla mm protection agents can be roughly divided into phosphorus-free or phosphorus-containing flame retardants.
- Preferred phosphorus-containing flame retardants are: bisphenol A disphenyl phosphate, triphenyl phosphate, tricresyl phosphate,
- RDP oligomeric resorcinol-bis (diphenyl phosphate)
- ammonium polyphosphate red phosphorus
- ammonium polyphosphate trimethyl phosphate
- TMP trimethyl phosphate
- HMP di (polyoxyethylene) hydroxymethylphosphonate
- PIR polyisocyanurate
- Preferred phosphorus-free flame retardants are: magnesium hydroxide, carbonate oligomers, alkali metal organosulfonate, ammonium octamolybdate (AOM), molybdenum oxide, aluminum hydroxide, co-metal oxides (eg MgO / ZnO, MoO 3 / ZnO), barium metaborate, magnesium sulfate heptahydrate, antimony oxide, zinc borate and calcium borate.
- step (ii) of the inventive method of the possible classes of additives namely plasticizers, flame retardants, processing aids and means for elastomer modification
- at least two classes of additives are used, more preferably at least three classes of additives, and particularly preferably all four classes of additives, ie at least one Weichma- tend, at least one flame retardant, at least one processing aid, and at least one means for elastomer modification.
- the addition amount of additives is total (in weight percent) of 0.5 to 40%, preferably 4 to 17%.
- the plastic has a particularly high toughness and elasticity example
- FIG. 1 shows a frame element for an electrochemical cell produced according to the invention by the injection molding process (material: the abovementioned polymer blend of PA6 and PA6.6).
- FIG. 1 also shows the position of the samples in the frame. The upper three samples are transverse to the flow direction and the lower three samples are longitudinal to the flow direction.
- plastic mixture according to the invention is particularly suitable for frame elements in electrochemical energy stores.
- thermogravimetric analysis TGA Only the influence of heat aging was considered. The other influences such as environmental influences, UV light etc. were neglected.
- the TGA was carried out with four different heating rates (5, 10, 15 and 20 K / min) under air with a sample weight of about 10 mg.
- Figure 2 shows the four TGA curves.
- the first is between 300 and 350 ° C
- the second between 400 and 470 ° C.
- the loss is between 40 and 70%.
- the lifetime is calculated from the kinetic equation of the thermal degradation reaction (based on the Arrhenius equation) for different temperatures of use.
- the relationship between temperature and weight loss can be determined. From this, the activation energy can be calculated. This is 10, 617 KJ / mol for the Gn7on ST-V0 polymer blend. With the help of the activation energy, the lifetime of the polymer can be determined at any operating temperature: Service life t f service temperature
- a service life of more than eight years at a temperature of 60 ° C is to be regarded as advantageous for the intended use of the frame elements.
