Definitions
- the present invention relates to aqueous dispersions of finely dispersed surface-deactivated solid isocyanates and to preparations containing these dispersions and their use for producing latent-reactive layers, films or powders for adhesive bonds or coatings.
- EP-A 0 204 970 describes a process for producing stable dispersions of finely divided polyisocyanates by treating the polyisocyanates in a liquid with stabilizers and exposure to high shear forces or grinding.
- Suitable diisocyanates and polyisocyanates are those whose melting point is above 10 ° C., preferably above 40 ° C.
- Mono- or poly-functional amine stabilizers with primary and / or secondary amine groups are used to produce the retarding or surface-deactivating polymer coating that surrounds the isocyanate particles.
- the dispersions described are used as crosslinkers.
- EP-A 0 505 889 describes aqueous dispersions of encapsulated polyisocyanates which are prepared by dispersing the isocyanates in water and reacting with primary or secondary polyamines with a molecular weight of less than 400 on the surface.
- the polyisocyanates can be used unmodified or hydrophilically modified.
- EP-A 0 467 168 discloses aqueous preparations made from copolymer dispersions and finely divided surface-deactivated polyisocyanate solid suspensions. They are used as coating agents for woven and non-woven substrates. Such compounds are described as deactivating agents which convert the isocyanate groups sitting on the surface to urea or polyurea structures, such as water or primary and secondary amines. The crosslinking of the coatings produced with these preparations takes place simultaneously with the drying in the heat.
- EP-A 0 922 720 describes aqueous dispersions which contain a surface-deactivated solid polyisocyanate and a polymer which is reactive with isocyanate.
- the dispersions are used for the preparation of late-reactive layers or powders which are stable in storage at room temperature and are crosslinked by heating above an activation temperature.
- the polyisocyanate dispersion is produced and the surface deactivated according to EP-A 0204 970.
- WO-A 99/58590 also describes storage-stable dispersion preparations containing surface-deactivated isocyanates, but which crosslink as dried films even at temperatures of less than 70 ° C.
- the deactivation consists in the reaction of the isocyanate groups exposed on the surface of the solid isocyanate particles to form urea structures. It has been found that dispersions of these, with mono- or polyamines as deactivating agent treated Feststoffisocyanate in water, especially when using relatively long-chain polyether amines, such as Jeffamine ® D 400 or Jeffamine ® T 403 (Huntsman Corp., Utah, USA) as Des131samin to after sedimentation, also stir gently.
- the object of the present invention is to deactivate the particles of the solids cyanate on the surface in such a way that the preparations obtainable therewith based on polymer dispersions have improved shear stability and the formation of coagulate tips is prevented.
- Polyamines with anionic or anion-forming groups and with primary and / or secondary amino groups can be used.
- the ionic groups are chemically anchored by reaction of the amino groups with the isocyanate groups to form urea groups on the surface of the polyisocyanate. A stabilizing sheathing of the otherwise unchanged polyisocyanate carrying anionic groups is thus produced.
- the present invention thus relates to surface-deactivated solid isocyanates obtainable by surface reaction of finely dispersed solid isocyanates with mono- or polyamines which contain anionic or groups capable of forming anions and which have primary and / or secondary amino groups.
- Resistance of the isocyanates to the reaction with water can be determined.
- Suitable solid isocyanates are difunctional and polyfunctional solid isocyanates or mixtures thereof, which have a melting point above 40 ° C., preferably above 80 ° C. Examples include diphenymethane-4,4'-diisocyanate (4,4'-
- MDI naphthalene-1,5-diisocyanate
- NDI naphthalene-1,5-diisocyanate
- 1,4-phenylene diisocyanate dimeric 1-methyl-2,4-phenylene diisocyanate (dimeric of 2,4-TDI), 3,3-disocyanato-4, 4'-dimethyl-N, N-diphenylurea (TDIH) or the isocyanurate of isophorone diisocyanate (IPDI).
- Preferred polyisocyanates are the dimer of 2,4-TDI, TDIH and the isocyanurate (trimerization product) of IPDI.
- the dimeric 2,4-TDI is particularly preferred.
- monoamines or polyamines with primary and / or secondary amino groups are used which carry terminally or laterally anionic or anionic groups, in particular carboxylate and / or sulfonate grapples, on the molecule as part of the molecular structure.
- the deactivation (or also “stabilization") of the solid isocyanate consists in the reaction of the deactivating agent with the isocyanate groups exposed on the surface of the solid isocyanate particles to form urea structures.
- Suitable deactivating agents are, for example, the salts, especially alkali
- salts of ⁇ -amino acids such as those of glycine, lysine, glutamic acid and aspartic acid are preferred.
- Preferred salts of ⁇ -amino acids have the general formula H 2 NR-COO (_) X (+) , where R is a hydrocarbon
- Radical having 2 to 17 carbon atoms and X stands for an alkali cation or for a substituted ammonium group.
- Examples include the salts of aminopropionic acid ( ⁇ -alanine), 4-aminobutyric acid and 6- aminocaproic acid.
- a and B are a hydrocarbon radical with 2 to 6 carbon atoms, preferably with 2 carbon atoms.
- X (+) represents an alkali cation or a substituted ammonium group.
- Preferred aminosulfonates are diamino sulfonates with the general formula (II),
- X ⁇ represents an alkali cation or a substituted ammonium group.
- a particularly preferred diammosulfonate compound of the general formula (II) is the sodium salt of 2- (2-aminoethylamino) ethanesulfonic acid.
- Deactivating agent leads to low viscosities of the dispersions containing the surface-deactivated solid isocyanates according to the invention, which e.g. In the case of dispersion in bead mills, this represents a considerable advantage in terms of processing, since the dispersion can be separated off much more easily than with the very pasty dispersions, such as those used when nonionic
- Stabilizing amines are formed.
- the present invention also relates to a process for the preparation of the solid isocyanates which have been deactivated according to the invention, characterized in that finely divided solid isocyanates, with dispersion in a liquid medium, are reacted with mono- or polyamines carrying primary and / or secondary amino groups, which are reacted via anionic or groups capable of forming anions (deactivation amine). Deactivation can be carried out in different ways:
- the deactivating agent does not have to be completely in solution. In general, it is an aqueous solution or a solution in another liquid medium that does not dissolve the isocyanate.
- Low-melting polyisocyanates can be dispersed and deactivated by introducing the melt into a solution of the deactivating agent cooled below the solidification temperature of the isocyanate. In general, it is an aqueous solution or a solution in another liquid medium which does not dissolve the isocyanate.
- the solvent and the dispersing medium are generally water or another liquid medium which does not dissolve the isocyanate.
- Particle sizes of the solid isocyanates of less than 50 ⁇ m, preferably less than 20 ⁇ m and particularly preferably less than 10 ⁇ m are required for the surface-deactivated solid isocyanates according to the invention. This required particle size is achieved by grinding the solid isocyanates prior to dispersion and subsequent deactivation, or alternatively by combining the deactivation process with the fine distribution by carrying out the dispersion using suitable grinding and dispersing devices in the presence of the deactivating agent.
- Devices suitable for the fine-particle dispersion are, for example, dissolvers, rotor-stator-type dispersing devices, ball mills or bead mills, the temperature should not exceed 40 ° C. Isocyanate melts can also be dispersed using jet dispersers.
- the ratio of the amino groups to the total isocyanate groups present in the solid isocyanate is 0.001 to 0.3, preferably 0.05 to 0.15 and particularly preferably 0.01 to 0.1.
- the degree of deactivation of the isocyanate can be changed by varying the specified isocyanate / amine ratios upwards or downwards at the expense of the later activatability of the dry latent-reactive film.
- the amount of amine increases the density of the urea on the surface of the polyisocyanate particles and thus the deactivating shell is more stable.
- the liquid, preferably aqueous medium used for the deactivation and fine distribution of the polyisocyanate can, in addition to the deactivation amine
- emulsifiers Contain emulsifiers, thickeners, protective colloids and optionally stabilizers, anti-aging agents, fillers, color pigments, plasticizers, non-solvent liquids and other auxiliaries.
- the present invention also relates to preparations comprising the solid isocyanates deactivated according to the invention and isocyanate-reactive dispersions of homo- and copolymers of olefinically unsaturated monomers and / or polyurethane dispersions and, if appropriate, auxiliaries and additives.
- the isocyanate-reactive aqueous dispersions of homo- and copolymers of olefinically unsaturated monomers and polyurethane dispersions known per se are used for the preparations containing the deactivated solid isocyanates according to the invention.
- the proportion of the deactivated solid isocyanate, based on the polymer proportion is in the range from 0.5 to 20% by weight, preferably in the range from 2 to 10% by weight.
- the range from 3 to 5% by weight is particularly preferred.
- the preparations may contain further polymer dispersions, including those without isocyanate-reactive groups, furthermore emulsifiers, thickeners, protective colloids and optionally stabilizers, anti-aging agents, fillers, color pigments, plasticizers, non-solvent liquids and other auxiliaries.
- the proportion of isocyanate-reactive polymer dispersions is 20-99.9% by weight of the preparation, the proportion of solid-state isocyanates deactivated according to the invention is 0.1-13% by weight, and the proportion of auxiliaries and additives is 0-79.9% .-%.
- Suitable polymers of olefinically unsaturated monomers are e.g. in EP-A 0 206 059. These are, for example, homopolymers and copolymers based on acrylic esters of C 1 -C 4 -alcohols or homopolymers and copolymers based on vinyl esters of carboxylic acids having 2 to 18 carbon atoms, preferably having 2 to 4 C atoms, such as Vinyl acetate. These can optionally contain up to 70% by weight, based on the total amount of other olefinically unsaturated monomers and / or homo- or copolymers
- Isocyanate-reactive functions result from the co-polymerization of OH- or NH-functional monomers, e.g. Hydroxyethyl or hydroxypropyl (meth) acrylate, butanediol monocrylate, ethoxylated or propoxylated (meth) acrylates, N-methylol-acrylamide, tert-butylamino-ethyl methacrylate or (meth) acrylic acid.
- Glycidyl methacrylate and allyl glycidyl ether can also be copolymerized. The subsequent reaction of the epoxy groups with amines or amino alcohols then leads to secondary amino groups.
- aqueous dispersions of polymers or copolymers of 2-chlorobutadiene-1,3, optionally with other olefinically unsaturated monomers of the type mentioned above by way of example are also suitable.
- These dispersions have, for example, a chlorine content of 30 to 40% by weight, preferably one chlorine content from 36% by weight.
- the reactivity of the a priori non-isocyanate-reactive polymers of 2-chlorobutadiene results from an exchange of hydrolyzable Cl groups for OH groups in the course of the manufacturing process or according to EP-A 0 857 741. (Examples of polychloroprene dispersions with different degrees of hydrolysis, Table 1 , Page 5 with CR dispersions 1 to 4).
- Suitable aqueous polyurethane dispersions are those as described in the prior art, e.g. in US-A 3 479 310, US-A 4 092 286, DE-A 2 651 505, US-A 4 190566, DE-A 2 732 131 or DE-A 2 811 148.
- Preferred polymer dispersions are isocyanate-reactive polyurethane and / or polyurea dispersions and polymers of 2-chlorobutadiene.
- Dispersions of isocyanate-reactive polyurethanes are particularly preferred which are composed of crystallized polymer chains which, when measured by means of thermomechanical analysis, at temperatures of +23 ° C. to +110 ° C., preferably at temperatures of
- the preparations according to the invention can contain auxiliaries and additives, such as emulsifiers, thickeners, protective colloids and stabilizers, fillers, color pigments, plasticizers or catalysts and other auxiliaries such as those used in the prior art for the formulation of aqueous Dispersion adhesives or coating agents can be used.
- auxiliaries and additives such as emulsifiers, thickeners, protective colloids and stabilizers, fillers, color pigments, plasticizers or catalysts and other auxiliaries such as those used in the prior art for the formulation of aqueous Dispersion adhesives or coating agents can be used.
- the preparations according to the invention are distinguished by a much better shear stability and, above all, by the prevention of the formation of coagulate specks which disrupt spray processing. After drying, very uniform, optically homogeneous streak-free and smooth layers with such a high surface quality result that they are not only suitable as adhesive layers, but also for producing optically appealing surface coatings.
- the present invention furthermore relates to the use of the surface-deactivated solid isocyanates for the production of latent-reactive coatings.
- Latent reactivity is understood to mean that possible crosslinking reactions of the polymer with the isocyanate present do not occur either in the ready-to-use preparation or in the coating which has already dried. This enables storable preparations or coatings to be produced. Networking is only initiated by brief heat activation, but then proceeds in a few days at RT without additional heat. The coatings have a significantly increased softening temperature, water and solvent resistance.
- the present invention also relates to a latently reactive adhesive bond which can be obtained by applying the preparations according to the invention to the substrates to be bonded either on one side or on both sides, then drying and activating with brief supply of heat and simultaneous joining.
- the adhesive application dried on the substrate to be bonded is decrystallized by briefly heating, preferably for 30 to 60 seconds, to temperatures of + 65 ° C. to 110 ° C. and joined in the decrystallized state. This can be done by a two-sided order or by a one-sided order.
- the preparation according to the invention is applied to a substrate and dried and then pressed with a film material which has been plastically softened by heating. Through contact with the adhesive, the adhesive takes on a temperature above the decrystallization temperature of the polymer and the heat activation is triggered.
- Suitable substrates are all substrates that have sufficient adhesion to the adhesive film.
- Examples of such substrates are wood, wood fiber pressed material, thermoplastics, thermosets, textiles or leather.
- the present invention further provides latent-reactive adhesive films which can be obtained by applying the preparations according to the invention to a substrate, then drying and detaching them from the substrate as a film.
- Suitable substrates are those substrates which do not adhere well to the adhesive film so that the latent-reactive adhesive strip can be easily removed, such as Teflon, silicone rubber, siliconized paper or release agent-coated polished chrome or aluminum surfaces.
- the present invention likewise relates to latent-reactive powders which can be obtained by spray drying the preparations according to the invention.
- the adhesive films and powders produced in this way can be stored at temperatures below the decrystallization temperature of the polymer and crosslink when heated above this limit, but at least at temperatures of + 65 ° C. to + 110 ° C.
- Necal ® BX emulsifier Manufacturer: BASF AG, D-67056 Ludwigshafen
- IPDA Isophoronediamine
- DispercoU ® U 53 polyurethane dispersion with a decrystallization temperature of approx. 55 ° C, manufacturer Bayer AG, D-0214 Leverkusen
- Desmodur TT is deactivated with the following amines.
- DispercoU ® U 53 100 parts by weight of DispercoU ® U 53 are introduced and 10 parts by weight of the deactivated Desmodur ® TT suspensions are added with a dissolver. Since the deactivated suspensions of Desmodur ® TT all contain approx. 40% by weight of solid isocyanate, this amount corresponds to 4.0 parts by weight of TT. The mixtures are homogenized for 5 min. stirred at 1000 rpm.
- the viscosities of the mixtures are then in the range from 3800 to 13200 mPas.
- the viscosity stability during storage of the preparation is an important technical parameter for reproducible processing. For this reason, it is generally the subject of narrow specification limits.
- the thickened preparations are more stable, however, in the comparative examples la-lc and 2a-2c (Table 5), the formation of coagulate specks increases after some time. Only the preparations according to the invention with 3 a up to 3c stay free of specks. If these preparations according to the invention are applied to a smooth surface, very uniform layers with a smooth surface are obtained, while the comparative examples produced with amines not according to the invention have very uneven, rough surfaces due to the high content of specks.
- DispercoU ® U 53 200 g of DispercoU ® U 53 are introduced and mixed for 2 minutes and with 20 g of isocyanate dispersion in the Dispermat at 1000 rpm. Then about 6 ml of Borchigel ® L 75 (20% solution in water) are added and the formulation is shaken for a further 120 min at 1000 rpm. After 30, 60 or 120 minutes, samples are taken and spread on glass plates. Table 6 shows the assessment of the coagulation of the individual formulations.
- the ionically modified surface of the surface-deactivated Desmodur ® TT particles according to the invention results in a dispersion which is much more shear-stable than in the comparative examples 1c and 2c, which shows no signs of coagulum formation even after extreme shear stress (120 minutes), while in the best case the comparative examples already are coagulated after 60 minutes.
- the adhesive preparations produced according to II.2 (formulation with thickening) are tested immediately after their preparation and after 4 weeks of storage at RT.
- the adhesive formulation is applied to both sides of the 20 x 10 mm adhesive surface with a brush.
- the adhesive layer is 60 min. at 23 ° C / 50% rel. Moisture dried.
- the adhesive surfaces are irradiated for 10 seconds with an IR radiator from Funk (shock activation device 2000).
- a 10 second activation of the adhesive film on the NORA sample gives a surface temperature of 115 ° C.
- the decrystallization temperature of the polymer chain of the polyurethane dispersion used (DispercoU ® U 54) is 55 ° C.
- the adhesive is applied immediately after heat activation of the adhesive-coated test specimens by placing the activated adhesive layers against one another and pressing them in a press at 4 bar for one minute.
- the test specimens thus produced are 7 days at 23 ° C and 50% rel. Moist stored. Heat test:
- test specimens are loaded with 4 kg and in a heating cabinet within 30 minutes. tempered to 40 ° C. Then the test specimens with a linear heating rate of 0.5 ° C / min. heated to 150 ° C.
- the softening temperature i.e. the
