Definitions
- the present invention relates to salts of at least one imidazole of the general formula
- R 1 , R 2 , R 3 and R 4 are identical or different and represent hydrogen, an alkyl radical having 1 to 20, preferably 1 to 10, more preferably 1 to 4 carbon atoms or a substituted or unsubstituted aryl or arylalkyl radical with 6 to 10 carbon atoms, and at least one aliphatic or aromatic mono- or dicarboxylic acid.
- the invention further relates to a process for the preparation of these salts, their use as catalysts in the curing of polyepoxides and epoxy resins based on polyepoxides containing these salts.
- Epoxy resins are aliphatic, cycloaliphatic or aromatic oligomers containing oxirane groups and crosslinked with hardeners to give thermosets.
- Most epoxy resins are glycidyl ethers of bisphenol A from the reaction of bisphenol A with epichlorohydrin.
- the resins can be cured cold with polyfunctional amines or heat with multifunctional carboxylic acids or carboxylic anhydrides. This thermosetting proceeds to form ester and ether structures.
- Epoxy resins are used for a variety of uses, eg. As adhesives, paints, for components, large containers, etc. When used as technical construction materials, they are usually reinforced with glass fibers or carbon fibers.
- epoxides are a variety of polyepoxides having at least 2 1, 2-epoxide groups per molecule.
- the epoxide equivalent of these polyepoxides can vary between 150 and 4000.
- the polyepoxides may in principle be saturated, unsaturated, cyclic or acyclic, aliphatic, alicyclic, aromatic or heterocyclic polyepoxide compounds.
- suitable polyepoxides include the polyglycidyl ethers prepared by reaction of epichlorohydrin or epibromohydrin with a polyphenol in the presence of alkali.
- suitable polyphenols are resorcinol, pyrocatechol, hydroquinone, bisphenol A (bis (4-hydroxyphenyl) -2,2-propane), bisphenol F (bis (4-hydroxyphenyl) methane), bis (4-hydroxyphenyl ) - 1, 1-isobutane), 4,4'-dihydroxybenzophenone, bis (4-hydroxyphenyl) -1,1-ethane, 1, 5-hydroxy-naphthalene.
- suitable polyepoxides in principle are the polyglycidyl ethers of polyalcohols or diamines.
- polyglycidyl ethers are derived from polyhydric alcohols such as ethylene glycol, diethylene glycol, triethylene glycol, 1,2-propylene glycol, 1,4-butylene glycol, triethylene glycol, 1,5-pentanediol, 1,6-hexanediol or trimethylolpropane.
- polyepoxides are polyglycidyl esters of polycarboxylic acids, for example reactions of glycidol or epichlorohydrin with aliphatic or aromatic polycarboxylic acids such as oxalic acid, succinic acid, glutaric acid, terephthalic acid or dimer fatty acid.
- epoxides are derived from the epoxidation products of olefinically unsaturated cycloaliphatic compounds or of native oils and fats.
- epoxy resins which are derived by the reaction of bisphenol A or bisphenol F and epichlorohydrin (DGEBA or DGEBF).
- DGEBA or DGEBF epichlorohydrin
- mixtures of liquid and solid epoxy resins are used, the liquid epoxy resins preferably being based on bisphenol A and having a sufficiently low molecular weight.
- imidazole salts are sometimes referred to in the literature as curing agents and partly as catalysts.
- US Pat. No. 3,356,645 also describes imidazole salts of organic acids as curing agents or catalysts for the curing of epoxy resins.
- organic acids monocarboxylic acids having 1 to 8 carbon atoms, and lactic acid are mentioned.
- the imidazole salts which may optionally be substituted, are reacted with the acid in a molar ratio of 1: 1 for the preparation of the imidazole salts, or the acid is used in excess over the imidazole.
- the known hardeners or catalysts allow storage of the epoxy resins mixed with them at low temperature, and as the temperature increases, the curing of the resins by crosslinking occurs.
- these known systems are unsatisfactory in one respect: the temperature difference between the temperature at which the catalysed resins can be stored without crosslinking and the temperature at which effective crosslinking occurs is relatively large.
- the present invention therefore salts of the type mentioned, which are characterized in that the molar ratio of carboxylic acid: imidazole based on the functionality of the acid 1: 1, 1 to 1: 6, preferably 1: 2 to 1: 4.
- These base-rich salts act as latent accelerators for epoxy resins, and are very well suited for the rapid processing of epoxy resins.
- the salts are liquid at room temperature and can be easily mixed with epoxy resins.
- This mixture can be prepared before use and it can be easily heated to temperatures of up to about 80 0 C, for example, in the production of fiber-reinforced moldings to achieve complete wetting of the fibers.
- the material properties of the materials such as the glass transition temperature, the water absorption and the elasticity are positively influenced by the organic acid residues.
- a slight increase in temperature to about 100 0 C occurs a rapid cross-linking, ie the curing is accelerated by a factor> 2 compared to the 1: 1 salts.
- Suitable imidazoles are unsubstituted imidazole, and alkyl- or aryl-substituted imidazoles.
- alkyl-substituted imidazoles are 2-methylimidazole, 2-ethylimidazole, 2-ethyl-4-methylimidazole, 2,4-dimethylimidazole, butylimidazole, 4-butyl-5-ethylimidazole, 2-dodecyl-5-methylimidazole, 2,4,5 Trimethylimidazole, 2-undecenylimidazole, 1-vinyl-2-methylimidazole, 2-n-heptadecylimidazole, 2-undecylimidazole, 2-heptadecylimidazole, 1-propyl-2-methylimidazole, 1-cyanoethyl-2-methylimidazole, 1-cyanoethyl ⁇ ethyl-methylimidazole, 1-cyanoethyl-2-undecylimidazole, 1-cyanoethyl-2-phenylimidazole, 1-guana
- Suitable aryl substituted imidazoles are phenylimidazole, 2,5-diphenylimidazole, 2-phenylethylimidazole, 2-benzylimidazole, 2-methyl-4,5-diphenylimidazole, 2,3,5-triphenylimidazole, 2-styrylimidazole, 1- (dodecylbenzyl) -2 -methylimidazole, 2- (2-hydroxy-4-t-butylphenyl) -4,5-diphenylimidazole), 2- (3-hydroxyphenyl) -4,5-diphenylimidazole, 2-p-dimethylaropinophenyl) -4,5-diphenylimidazole , 2- (2-Hydroxyphenyl) -4,5-diphenylimidazole, 1-benzyl-2-methylimidazole, 2-p-methoxystyrylimidazole.
- Preferred imidazoles are unsubstituted imidazole, alkyl-substituted imidazoles having substituents having 1 to 6 carbon atoms, and aryl-substituted imidazoles having substituents having 6 to 8 carbon atoms.
- the carboxylic acids can be selected from the group consisting of substituted or unsubstituted, saturated or unsaturated monocarboxylic acids having 3 to 22 carbon atoms, substituted or unsubstituted, saturated dicarboxylic acids having 2 to 36 carbon atoms, substituted or unsubstituted, unsaturated dicarboxylic acids having 4 to 36 C atoms and substituted or unsubstituted aromatic mono- or dicarboxylic acids.
- carboxylic acids according to the invention are: unsaturated substituted or unsubstituted monocarboxylic acids having 3 to 5 carbon atoms and unsaturated substituted or unsubstituted dicarboxylic acids having 4 to 8 carbon atoms, for example acrylic acid, methacrylic acid or crotonic acid, fumaric acid, maleic acid or itaconic acid; saturated substituted or unsubstituted monocarboxylic acids having 1 to 5 carbon atoms and saturated substituted or unsubstituted dicarboxylic acids having 2 to 5 carbon atoms, for example formic acid, acetic acid, propionic acid, pivalic acid, oxalic acid, malonic acid or succinic acid; saturated or unsaturated substituted or unsubstituted monocarboxylic acids mt 6 to 22 carbon atoms, which may also contain cycloaliphatic structural elements, for example hexanoic acid, heptanoic acid, cyclohexane
- the invention also relates to a process for the preparation of the imidazole salts according to the invention, which is characterized in that at least one imidazole of the general formula

- the invention also relates to the use of the imidazole salts as catalysts in the curing of polyepoxides and epoxy resins based on polyepoxides having at least two epoxide groups per molecule, which contain the imidazole salts according to the invention.
- the proportion of imidazole salts is advantageously 0.01 to 40 wt .-%, preferably 1 to 10 wt .-% based on the total weight of epoxy resin and salt.
- the imidazole salts were prepared by reacting the starting materials indicated in the following table in said molar ratio.
- the Imidazolkomponenten were finely pulverized and mixed with vigorous stirring with the acid component. Stirring was continued at room temperature for 6 to 12 hours until a homogeneous phase formed.
- the imidazole salts were incorporated in an amount of 5 wt .-% based on the total weight of the mixture in an epoxy resin formulation.
- the tensile shear strength of the sample 1 of the invention was 4, to 8.3 MPa.
- the comparative samples showed values of tensile shear strength of 0.1 and 0.4 MPa, respectively.
- the results show that by the base-rich imidazole salts according to the invention a significant acceleration of the curing at 100 0 C occurs.
