Definitions
- the present invention relates to a novel solvent for polyamide-imides and polyimides as well as corresponding applications.
- Polyamide-imides are known and described for example in US 3,554,984, DE 2,441,020, DE 25 56 523, DE 12 66 427 and DE 19 56 512.
- Polyimides are also known and described for example in GB 898,651, US 3,207,728, EP 0 274 602, EP 0 274 121.
- the high quality wire coating agents commonly used today are generally solutions of typical binders, such as polyamide-imides and polyimides in solvents, optionally in combination with commercial hydrocarbon blends.
- the organic solvents with which polyamide-imides and polyimides are dissolved include amide solvents such as dimethylformamide, N, N-dimethylacetamide and N-methylpyrolidone (NMP). These solvents can be partially replaced by cosolvents.
- amide solvents such as dimethylformamide, N, N-dimethylacetamide and N-methylpyrolidone (NMP).
- NMP N-methylpyrolidone
- NMP To dissolve polyamide-imides or polyimides, especially when they are wholly aromatic, NMP must normally be used.
- the object of the present invention is therefore to find a new solvent or solvent mixture which is able to dissolve polyamide-irides and / or polyimides very well and no longer has the problems of the prior art solvents, nevertheless results should be achieved which are the same as those of the prior art State of the art equals.
- compositions in particular wire enamels, and processes for their preparation, which contain polyamideimides and / or polyimides and which can be formulated without solvent as NMP.
- room temperature means a temperature of 20 ° C. Temperature data are, unless stated otherwise, in degrees Celsius (° C.).
- Wholly aromatic polyamide-imides or wholly-aromatic polyimides are those in which the individual constituent components all consist of aromatic compounds.
- both polyamide-imides and polyimides can be excellently dissolved with this solvent.
- the present invention is therefore the use of 3-methoxy-N, N-dimethyIpropanamid as a solvent for polyamide-imides, for polyimides, for mixtures of polyamide-imides and polyimides, and for compositions containing polyamide-imide, polyimide or mixtures of these resins.
- the subject of the present invention is the use of 3-methoxy-N, N-dimethylpropanamide as a solvent for wire enamels whose binder component contains polyamide-imides and / or polyimides or from this consists.
- co-solvent preferably at least 70% by weight of 3-methoxy-N, N-dimethylpropanamide and at most 30% by weight of co-solvent, more preferably at least 80% by weight of 3-methoxy-N, N-dimethylpropanamide and at most 20% by weight of co-cutting agent and more preferably at least 90% by weight of 3-methoxy-N, N-dimethylpropanamide and at most 10% by weight of co-solvent, the percentages in each case based on the total weight of 3-methoxy-N, N- dimethylpropanamide and cosolvents, the compositions being, in particular, wire enamels.
- Not least object of the present invention is a process for the preparation of compositions, in particular wire enamels, by mixing the components, wherein the binder component polyamideimides and / or polyimides contains or consists of these, wherein as the solvent pure 3-methoxy-N, N-dimethylpropanamide or a mixture comprising at least 60% by weight of 3-methoxy-N, N-dimethylpropanamide and at most 40% by weight of extender, preferably at least 70% by weight of 3-methoxy-N, N-dimethylpropanamide and at most 30% by weight Coupling agents, more preferably at least 80% by weight
- the present invention is applicable to any polyamide-imides and / or polyimides, since the inventive solvent
- wholly aromatic polyamide-imides and / or polyimides are used in mixture with non-wholly aromatic polyamide-imides and / or polyimides.
- Polyamide-imides and polyimides should be referred to by way of example:
- the preparation of the polyamide-imides can be carried out, for example, in a known manner from polycarboxylic acids or their anhydrides in which two carboxyl groups are in the vicinal position and which must have at least one further functional group and polyamines having at least one primary, capable of imide bond amino group. Instead of the amine group, an isocyanate group can be used to form the imide ring.
- the polyamide-imides can also be obtained by reacting polyamides, polyisocyanates containing at least two NCO groups, and cyclic dicarboxylic anhydrides containing at least one further condensable or additionable group.
- the polyamide-imides from diisocyanates or diamines and dicarboxylic acids, if one of the components already contains an imide group.
- a tricarboxylic anhydride can be reacted with a diprimary diamine to form the corresponding diimidocarboxylic acid which then reacts with a diisocyanate to form the polyamideimide.
- tricarboxylic acids or their anhydrides in which the carboxyl groups are in the vicinal position.
- the corresponding aromatic tricarboxylic acid anhydrides e.g. Trimelllthklareanhydrid, Naphthalintricarbonklareanhydride, Biphenyltricarbonklareanhydride and other tricarboxylic acids with two benzene nuclei in the molecule and two vicinal carboxyl groups, such as the examples listed in DE-OS 19 56 512, Very particularly preferably trimellitic anhydride is used.
- the carboxylic anhydrides are reacted with diisocyanates in a suitable solvent, with elimination of carbon dioxide from the Anhydride imide structures are formed and from the carboxylic acid amide groups.
- diisocyanates examples include trimethylene diisocyanate, tetramethylene diisocyanate, pentamethylene diisocyanate, hexamethylene diisocyanate, propylene diisocyanate, ethylethylene diisocyanate, 3,3,4-trimethylhexamethylene diisocyanate, 1,3-cyclopenthyl diisocyanate, 1,4-cyclohexyl diisocyanate, 1,2-cyclohexyl diisocyanate, 1,3-phenylene diisocyanate.
- the imide structures can also be prepared by a reaction of the anhydride groups with diamines.
- diamines As an amine component diprimary diamines can be used which are first reacted with two moles of polycarboxylic acid. These are then built up on the remaining free carboxyl groups with diisocyanates to polyamide-imides.
- polyamide-imides and polyimides are well-known to the person skilled in the art, further detailed descriptions are unnecessary here. It is preferred in a variant of the present invention if the polyamide-imides and / or polyimides are completely aromatic.
- co-solvents which may optionally be used in addition to 3-methoxy-N, N-dimethylpropanamide in the context of the present invention preferably consist of pure hydrocarbon compounds or mixtures thereof, i. other atoms besides carbon and hydrogen are present at most as technical impurities.
- xylene preferably those selected from the group consisting of xylene, Solventnaphtha, toluene, ethylbenzene, cumene, Schwerbenzol, various types of Ci 0 -Ci3-aromatics, for example, the brand Solvesso (R) , various types of hydrocarbons, aromatic-rich Kohlertwasserstoffgemische, for example, the brand DeasoF , and mixtures thereof.
