Definitions
- the invention relates to curable mixtures of aromatic cyanates or cyanate-epoxy mixtures, aromatic amines and optionally catalysts for the production of thermosets based on polytriazine. It further relates to the thermosetting compositions obtainable by curing these mixtures and their use for the production of molded parts.
- polytriazines obtainable from bifunctional or polyfunctional aromatic cyanates, and the thermosets obtainable from the cyanates and epoxy resins mentioned, are valuable materials because of their outstanding heat resistance and good dielectric properties.
- Polyfunctional cyanates, epoxides or amines are understood here and below to mean compounds which contain three or more cyanate, epoxy or amino groups in one molecule.
- the starting materials mentioned can also be cured by purely thermal means, they are usually carried out by adding catalytically active transition metal compounds such as cobalt or copper acetylacetonate or zinc octanoate (“zinc octoate”).
- catalytically active transition metal compounds such as cobalt or copper acetylacetonate or zinc octanoate (“zinc octoate”).
- zinc octoate zinc octanoate
- the object of the present invention was therefore to provide alternative additives for curing aromatic cyanates and cyanate-epoxy mixtures which do not have the disadvantages mentioned.
- this object is achieved by the curable mixtures according to claim 1. It was surprisingly found that by using aromatic amines as hardeners of bifunctional or polyfunctional cyanates or their mixtures with epoxides, it is not only possible to dispense with catalysts containing heavy metals, but also to obtain products with outstanding properties after curing. In particular, the glass temperature (T g ) is significantly increased and the hardened Products have improved impact strength. In addition, through-hardening is improved and the hardening process, in particular the latency during hardening, is improved.
- the curable mixtures according to the invention contain at least the following constituents:
- Transition metal compounds are understood to mean both salts and coordination compounds, the transition metals being in particular those of the first and second transition series. These include, for example, coordination compounds such as cobalt or copper acetylacetonate, or salts such as zinc octanoate or zinc stearate. Boron trihalides are in particular boron trifluoride and boron trichloride.
- bifunctional or polyfunctional aromatic cyanates are preferably those from the group consisting of the compounds of the general formulas
- n is a number from 0 to 10 and R is hydrogen or methyl
- n has the meaning given above.
- Mixtures of these compounds, prepolymers of these compounds, prepolymers of mixtures of these compounds and mixtures of prepolymers of these compounds can also be used.
- Prepolymers are understood to mean the oligomers obtainable by partial trimerization. These contain triazine groups formed by trimerization as well as unreacted cyanate groups.
- the cyanates are known compounds and for the most part are commercially available, likewise the prepolymers are known and in some cases are commercially available or can be easily prepared from the cyanates.
- Epoxy resins are preferably those from the group consisting of the compounds of the general formulas
- R and X have the meanings given above, and the corresponding oligomers
- n and R have the meanings given above;
- n has the meaning given above.
- Aromatic amines are preferably those from the group consisting of the compounds of the general formulas
- R 3 , R 4 and R 5 are independently hydrogen, C 1-4 alkyl or halogen
- R 6 , R 7 and R 8 independently of one another are hydrogen or C 1-4 alkyl. These compounds are also known and for the most part are commercially available. Compounds of the formula VII are used, for example, as chain extenders in polyurethanes and those of the formula VIII as amine components in polyureas or as starting materials for the preparation of isocyanates.
- the invention also relates to the polytriazine-based thermosetting compositions obtainable by thermal curing of the mixtures described above, optionally with the addition of fillers and / or auxiliaries.
- Fillers and auxiliaries include, in particular, reinforcement materials in the form of fabrics, fibers or particles, dyes or other additives to achieve special mechanical, optical, electrical or magnetic properties or to improve the processing properties. to understand properties.
- These fillers and auxiliaries are known to the person skilled in the art.
- thermosetting compositions thus obtainable for the production of molded parts for electronic devices, air and space vehicles, road and rail vehicles and water vehicles and industrial purposes is the subject of the invention.
