Definitions
- the invention relates to an activator for cyanoacrylate adhesives based on N, N-dialkyl aniline derivatives, their production and use, and the combination product of them and the cyanoacrylate adhesive.
- Activator is generally understood to mean an accelerator to be used separately for curing a chemically reacting one-component adhesive.
- the polymerization of in particular 2-cyanoacrylic acid esters is activated.
- Activators of the generic term are known.
- particles from a porous carrier which are impregnated with an N, N-dialkyl-substituted aniline having 1 to 4 carbon atoms in the alkyl radical, are used to trigger a delayed polymerization of monomeric cyanoacrylates. The delay is caused by the porous supports.
- the N, N-dialkyl-substituted anilines are N, N-dimethylaniline, N, N, 2,4-tetramethylaniline, N, N, 3,5-tetramethylaniline, N, N, N-dimethyl-o-toluidine , N, N-dimethyl-m-toluidine, N, N-dimethyl-p-toluidine, N-methyl-N-phenylbenzylamine and / or their corresponding N-ethyl and N, N-diethyl derivatives.
- N, N-Dimethyl-p-toluidine is preferred.
- the adhesive bonds obtained are not transparent.
- the invention is used in the dental field.
- the disadvantage here that N, N-dimethyltoluidine is toxic and smells unpleasant has a particularly negative effect.
- N, N-dimethyl-toluidine for activating cyanoacrylic acid esters is still commercially available. Since this is a T substance in the sense of the Chemicals Act, this activator must be specified at a concentration of more than 1%. Further disadvantages of the known activator are the volatility, which also releases DMT after the bonding, and the associated unpleasant smell. The invention aims to remedy this situation and to provide an activator which does not have these disadvantages or does not have them practically and is better in terms of handling and usage properties than the known activators, in particular balanced in terms of discoloration, transparency, intrinsic odor, curing behavior, strength and surface structure is.
- R1 is a CH3 or C2H5 radical
- m is a number of 0 or 1
- R 2 is H or CH 3 ⁇ and p is a number from 0 to 10.
- the activator is essentially based on the action of the aniline derivatives according to the invention.
- it can also contain inert liquid or solid substances.
- the dialkyl aniline derivatives according to the invention are predominantly used in the form of a solution in organic solvents.
- the solvent should not only dissolve the dialkylaniline derivatives according to the invention, but also be soluble in the monomeric cyanoacrylate. In addition, it should be inert towards the dialkyl aniline derivatives according to the invention and light at room temperature evaporate.
- Suitable solvents are ketones such as acetone and methyl ethyl ketone, esters such as ethyl, propyl or butyl ester, chlorinated hydrocarbons such as methylene chloride or 1,1,1-trichloroethane, aromatic hydrocarbons such as toluene and aliphatic hydrocarbons such as n-heptane.
- dialkyl aniline derivatives according to the invention are advantageously dissolved in a concentration of 0.1 to 5% by weight, preferably in a concentration of 0.5 to 2% by weight.
- the solution can also contain other substances, for example dyes or optical brighteners, in order to be able to better control the application.
- solutions with the aniline derivatives according to the invention can be applied in fine distribution to the surfaces to be treated by immersion, spraying, brushing or other suitable processes. They can be applied to the parts to be joined both before, after and before and after the cyanoacrylate adhesive. An activator is preferably applied before or after.
- the activator according to the invention can also advantageously be processed with powder to form a paste, mixed with cyanoacrylate adhesive and then filled with adhesive joints or cavities.
- N, N-dialkyl compounds are N, N-dimethyl compounds, i.e. R ⁇ is preferably a methyl group.
- a third substituent can be present, namely an alkyl group with 1 to 3 carbon atoms, preferably 1 carbon atom.
- the invention also relates to a combination product for bonding parts to be bonded which, in addition to the N, N-dialkyl derivatives according to the invention, also contains a cyanoacrylate adhesive.
- the cyanoacrylate adhesive consists essentially of monomers
- Cyanoacrylates of the general formula H2C C (CN) -C00R.
- R is an alkyl, alkenyl, cycloalkyl, aryl, alkoxyalkyl, aralkyl or haloalkyl group, in particular a methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl group -, pentyl, hexyl, allyl, methailyl, crotyl, propargyl, cyclohexyl, benzyl, phenyl, cresyl, 2-chloroethyl, 3-chloropropyl, 2-chlorobutyl, trifluoroethyl, Is 2-methoxyethyl, 3-methoxybutyl and 2-ethoxyethyl group.
- They can also act like a primer, i.e. increase the adhesive strength after priming.
- the activators were investigated according to the following criteria: a) curing speed with subsequent activation, b) transparency and c) own smell of the activator.
- the curing speed on a subsequently activated surface was determined as follows:
- a drop and a bead of cyanoacrylate adhesive are dosed onto degreased aluminum test strips. Premature polymerization is achieved by subsequent spraying with a 2% activator solution. In practice, this is a process for curing excess adhesive.
- the activator according to the invention had a far less unpleasant smell than DMT.
- the appearance of the adhesive cured with the activators according to the invention corresponds to that of the adhesive activated with dimethyltoluidine. This also applies in particular to transparency and colorlessness. The strength and curing times were practically the same.
