Definitions
- Silane-crosslinking adhesives or sealants process for their preparation and their use
- the present invention relates to silane-crosslinking adhesive or sealant compositions comprising a) at least one polymer of the general formula (I)
- R 1 is an alkyl radical having 1 to 8 C atoms
- R 2 is an alkyl or alkoxy radical having 1 to 8 C atoms
- A is a carboxy, carbamate, carbonate radical , Ureido, urethane or sulfonate bond or an oxygen atom
- adhesion promoters adhesion promoters, drying agents and / or reactive diluents.
- Silane-crosslinking adhesives and sealants contain alkoxysilane-terminated polymers as binders.
- Polymer systems that have reactive alkoxysilyl groups have long been known. In the presence of atmospheric moisture, these alkoxysilane-terminated polymers are capable, even at room temperature, of condensing one another with elimination of the alkoxy groups.
- mainly long-chain polymers thermoplastics
- relatively wide-meshed three-dimensional networks elastomers
- highly crosslinked systems thermosets
- the polymers typically have an organic backbone bearing alkoxysilane groups at the ends.
- the organic skeleton may be, for example, polyurethanes, polyesters, polyethers, etc.
- a one-component reactive system composition which contains an alkoxysilane-terminated polyurethane, a curing catalyst and optionally conventional additives.
- WO 99/48942 A1 discloses alkoxysilane-terminated polyurethanes and corresponding polyurethane-containing preparations which, in addition to the alkoxysilated polyurethanes, may contain solvents, catalysts, plasticizers, reactive diluents, fillers and the like.
- the polymeric backbone may also contain organosiloxane in addition to organic components, as described in WO 96/34030 A1.
- the alkoxysilane end group-containing polymers used in the prior art generally contain methoxysilane end groups. These binders are often used as a replacement for NCO-terminated polyurethanes and have significant toxicological advantages for the processor due to the isocyanate-free. However, a disadvantage is the elimination of small amounts of methanol during curing.
- the currently customary silane-terminated polymers generally contain dimethoxymethylsilyl or trimethoxysilyl end groups. Replacement of the methoxy groups with ethoxy groups reduces the reactivity of the polymers to such an extent that the curing rate of the adhesives is no longer acceptable.
- the present invention therefore provides adhesives or sealants of the type mentioned, which are characterized in that the adhesion promoters, desiccants and / or reactive diluents containing ⁇ -silanes ethoxy groups of the general formula (II)
- R 3 is an organic radical connected via a heteroatom to the methylene group and R 4 is an alkyl radical having 1 to 8 C atoms or an ethoxy radical.
- the radical R 3 in the general formula (II) is advantageously a methacryloxy or carbamate radical, an amino group or an alkoxy radical.
- the polymeric backbone R is a mono- to tetravalent, preferably a di- or trivalent, hydrocarbon radical which may contain heteroatoms and / or organosiloxane groups.
- Examples of the polymeric backbone are alkyd resins, oil-modified alkyd resins, unsaturated polyesters, natural oils, e.g. As linseed oil, tung oil, soybean oil, as well as epoxies, polyamides, thermoplastic polyesters such.
- polyethylene terephthalate and polybutylene terephthalate polycarbonates, polyethylenes, polybutylenes, polystyrenes, polypropylenes, Ethylenpropylenco- and terpolymers, acrylates, for. B. homopolymers and copolymers of acrylic acid, acrylates, methacrylates, acrylamides, their salts and the like, phenolic resins, Polyoxymethylenhomo- and copolymers, polyurethanes, polysulfones, polysulfide rubbers, nitrocellulose, vinyl butyrates, vinyl polymers, eg.
- ethyl cellulose, CeIIu loseacetate and butyrates, rayon, shellac, waxes, Ethylencoplymere such.
- Ethylene acrylate copolymers organic rubbers, silicone resins and the like.
- Other examples include polyethers such as polyethylene oxide, polypropylene oxide and polytetrahydrofuran.
- polyethers, polyesters and polyurethanes are particularly preferred.
- adhesion promoters, desiccants and / or reactive diluents ⁇ -silanes are selected from the group consisting of ⁇ -amino, ⁇ -methacrylic, ⁇ -carbamatosilanes and ⁇ -alkoxysilanes.
- Suitable examples are N-cyclohexylaminomethylmethyldiethoxysilane, N-cyclohexylaminomethyltriethoxysilane, N-phenylaminomethyltriethoxysilane, (methacryloxymethyl) methyldiethoxysilane and methacryloxymethyltriethoxysilane, N- (triethoxysilylmethyl) -O-methyl-carbamate and N- (methyldiethoxysilylmethyl) -O-methyl-carbamate.
- the adhesives and sealants in addition to the polymer and the ⁇ -silane as a further component fillers.
- Suitable fillers are for. As chalk or lime, precipitated and / or fumed silica, zeolites, bentonites, ground minerals and other familiar to the expert inorganic fillers.
- organic fillers can also be used, in particular fiber short cuts and the like.
- fillers are preferred which impart thixotropy to the adhesive or sealant compositions, e.g. B. swellable plastics such as PVC.
- the adhesives and sealants in addition to the polymer and the ⁇ -silane and the fillers contain other conventional additives such as plasticizers, solvents, UV stabilizers, antioxidants, catalysts, desiccants, reactive diluents and adhesion promoters.
- the adhesive or sealant compositions according to the invention advantageously contain 5 to 90, preferably 10 to 70 parts by weight, more preferably 15 to 50 parts by weight of polymer a) and 0.1 to 10 parts by weight of ⁇ -silane.
- the invention also relates to a process for preparing the silane-crosslinking adhesive or sealant compositions, which is characterized in that the polymer a), the ⁇ -silanes b) and optionally fillers are mixed together.
- the polymer a), the ⁇ -silanes b) and optionally fillers are mixed together.
- the invention further relates to the use of the adhesive compositions according to the invention for bonding wood, plastics, metals, mirrors, glass, ceramics, mineral substrates, leather, textiles, paper, cardboard and rubber, wherein the materials can be bonded to each other with themselves or with each other ,
- the invention also relates to the use of the adhesive composition of the invention as a reactive postcrosslinking pressure-sensitive adhesive.
- the invention relates to the use of the sealant compositions of the invention as a sealant mass.
- the compositions of the invention can also be used as a surface coating agent, as a water vapor barrier, as a dowel, perforated or cracked filler and for the production of molded parts.
- Polymer 1 ( ⁇ -triethoxysilyl-terminated polypropylene glycol):
- Polymer 2 ( ⁇ -trimethoxysilyl-terminated polypropylene glycol):
- Kaneka MS Polymer S 303 H 1 a dimethoxymethylsilyl-terminated polymer from Kaneka, was used as polymer 4.
- AMMO aminopropyltrimethoxysilane
- AMEO aminopropyltriethoxysilane
- DBTL dibutyltin dilaurate
- DBTAc dibutyltin acetonate
- An adhesive formulation based on ⁇ -methoxysilyl-terminated polypropylene glycol and methoxysilanes has good properties, but it does split off> 2% of methanol (Comparison 3).
- An adhesive formulation based on ⁇ -methoxysilyl-terminated polypropylene glycol and ethoxysilanes has good properties, eliminating ⁇ 0.3% of methanol (Examples 1 and 3).
