Definitions
- the invention relates to the use of a polyol for the production of an isocyanate casting resin.
- polyols which can be prepared by ring opening epoxidized fatty acid esters of polyhydric alcohols derived from natural fats and oils with aliphatic hydroxy compounds having functionality 1 to 10. They are suitable for the production of aqueous polyurethane dispersions.
- DE 41 22530 describes the preparation of fatty acid lower alkyl esters from fatty acid glycerides and lower aliphatic alcohols. The products are characterized by a low content of bound glycerol and a low acid number. There is no question of epoxidation.
- a composition which A) consists of an isocyanate compound with functionality 2 to 10 and B) an essentially water-free polyol which contains more than 10 carbon atoms and 2 or more hydroxyl groups and which by reaction of epoxidized fatty alcohols, fatty acid esters or fatty acid amides with aliphatic or aromatic alcohols with functionality 1 to 10 and / or with di- or trifunctional phenols with epoxy ring opening and, if desired, transesterification of the fatty acid esters and / or subsequent reaction with C2-C4 epoxides has been produced. Both components can be stored separately until they are used. At least one of the two components can contain further additives such as solvents, accelerators, fillers or auxiliaries.
- a disadvantage of the polyester polyols is the poor resistance of the cured polyurethane compositions to chemicals, especially strong alkalis.
- DE 4041 119 A discloses the use of polyfunctional unsaponifiable alcohols as an additive to polyol components in the production of polyurethanes.
- the alcohols are produced by ring-opening reaction of epoxidized olefins and / or epoxidized alcohols with low molecular weight diols and / or triols. The addition serves to improve the hydrolysis stability of the polyurethane.
- the polyurethane resin was used as an adhesive. There is no question of using it as a casting resin or coating. "Coating” is understood to mean the application of a firmly adhering layer made of an informal substance to a workpiece or a carrier web.
- Casting resins are known to be liquid synthetic resins or those which can be liquefied by moderate heating, which are poured into open molds and harden there. Casting resins also include isocyanate casting resins. According to DIN 55958, this means synthetic resins which are based on aliphatic, cycloaliphatic or aromatic isocyanates and still contain free isocyanate end groups. They can be cured under various conditions.
- a one-component casting resin consists of a polyurethane prepolymer with terminal free or blocked isocyanate groups which cure when exposed to moisture, which can be heated, for example to accelerate the reaction or increase strength.
- a two-component casting resin is based, for example, on polyhydroxy compounds based on branched polyesters or polyethers as the first component and on polyisocyanate as the second component. After the two components have been mixed, they cure at room temperature or at a slightly elevated temperature. Such two-component casting resins are used, for example, for the casting of cable fittings.
- the solution according to the invention can be found in the patent claims. It consists essentially in the use of the polyols according to EP 152585, which are based on fatty acid esters, for the production of an isocyanate casting resin or a coating composition.
- the invention thus consists in the use of a polyol with more than 10 carbon atoms and 2 or more hydroxyl groups for an isocyanate casting resin or for a coating composition, the polyol being obtained by reacting fatty acid esters with aliphatic or aromatic alcohols of functionality 1, in particular 2 to 10 and / or with di- or trifunctional phenols with epoxy ring opening and, if desired, transesterification of the Fatty acid ester and / or subsequent reaction with C2 to C4 epoxides has been prepared.
- a preferred group of polyols for two-component casting resins for the purposes of the invention are the ring opening products of epoxidized fatty acid esters with aliphatic alcohols of functionality 1, in particular 2 to 10.
- a subgroup of these compounds are the ring opening products of epoxidized fatty acid esters, in particular triglycerides, i.e. epoxidized fatty acid glycerol esters, in which the Ring opening has been carried out while maintaining the ester bond.
- Such connections are particularly easily accessible and can be produced in a wide range of variations.
- a large number of epoxidized triglycerides of vegetable or animal origin can be used to produce the ring opening products. The only requirement is that there is a substantial proportion of epoxy groups.
- epoxidized triglycerides are suitable which have 2 to 10 percent by weight of epoxy oxygen. Products with an epoxy oxygen content of 3 to 5 are particularly suitable for some applications. This can be adjusted by starting from triglycerides with a relatively low iodine number and exhaustively epoxidizing them or by starting from triglycerides with a high iodine number and only partially converting them to epoxides he follows.
- Another product group suitable for other purposes is based on epoxidized triglycerides with an epoxy oxygen content of 4 to 8.5%.
- Products of this type can be produced from the following fats, oils (sorted according to increasing starting iodine number): beef tallow, palm oil, lard, castor oil, peanut oil, rapeseed oil and preferably cottonseed oil, soybean oil, tran oil, sunflower oil, linseed oil.
- Particularly preferred raw materials are epoxidized soybean oil with an epoxy number of 5.8 to 6.5, epoxidized sunflower oil with an epoxy number of 5.6 to 6.6, epoxidized linseed oil with an epoxy number of 8.2 to 8.6 and epoxidized tran oil with an epoxy number of 6.3 to 6.7.
- the epoxidized triglycerides can be subjected to the complete ring opening with polyfunctional alcohols or also the partial ring opening. Modified triglycerides with an average of epoxy and hydroxyl and ether groups are formed during the partial ring opening.
- the manufacture of such products is the subject of the older German patent application P 3246612.9.
- triglycerides of a fatty acid mixture containing at least partially olefinically unsaturated fatty acids with mono- or polyhydric alcohols are subjected to the partial ring opening by the reaction by destroying or removing the catalyst and / or the alcohol reactant after a conversion of 20 to 80 mol%, based on epoxy groups, is stopped.
- the complete or partial ring opening of the epoxidized triglycerides with hydroxy compounds of functionality 2 to 10 can be carried out according to the process known for the epoxidized fatty alcohols (see EP 152585 A).
- the hydroxy compounds already described there are also suitable.
- epoxidized fatty acid triglycerides instead of epoxidized fatty acid triglycerides, other epoxidized fatty acid esters of polyfunctional alcohols can also be used. So epoxidized trimethylolpropane, fatty acid methyl ester, ethyl ester and / or -2-ethyl-hexyl ester can be used in the same way and can be processed into partial or full ring opening products with one of the aforementioned multifunctional or onofunctional alcohols.
- a particularly important class of polyols suitable according to the invention for two-component casting resins are ring opening and transesterification products of epoxidized fatty acid esters of onofunctional C 1 to C 1 alcohols, in particular C 1 -C 6 alcohols, that is to say, for example, of epoxidized fatty acid methyl, ethyl, propyl or -butyl esters.
- the ring opening and transesterification products with alcohols of functionality 2 to 4 are preferred here, in particular the reaction products with ethylene glycol, propylene glycol, 1,2-propanediol, 1,4-butanediol, 1,6-hexanediol, oligomeric ethylene glycols, oligomeric propylene glycols, the reaction products with glycerol, trimethylolpropane or pentaerythritol and mixtures of these alcohols. Products of this type can be produced by known epoxidation and ring opening processes.
- Ring opening and transesterification products are preferred in which a ratio between epoxidized fatty acid esters and the alcohol used for the reaction of 1: 0.1 to 1:10, in particular 1: 0.5 to 1: 4, has been used.
- Analogous to the opening products of epoxidized fatty alcohols, 1: 1 or 1: 2 adducts can also be produced here.
- the monoalcohol of the fatty acid esters should preferably have 1 to 18, in particular 1 to 8, carbon atoms, methanol, ethanol or 2-ethylhexanol being the most expedient.
- the aliphatic or aromatic alcohols preferably have a functionality of 2 to 4 and contain 1 to 36 C atoms, in particular 2 to 12.
- Fatty acids are understood to mean carboxylic acids with almost exclusively unbranched carbon chains, in particular with more than 8 carbon atoms, preferably with 12 to 36 carbon atoms.
- the following may be mentioned as monounsaturated fatty acids: palitoleic, oleic and erucic acid.
- polyunsaturated fatty acids can also be used, e.g. Linoleic and linolenic acid. They can be obtained from fats and oils of natural origin, e.g. from palm, beet, linseed, oil of oil, castor, castor, peanut and soybean and beef tallow.
- a preferred group of polyols for two-component casting resins for the purposes of the invention are the ring opening products of epoxidized fatty acid esters with aliphatic alcohols with functionality 2 to 10.
- a particularly important subgroup of these compounds are the ring opening products of epoxidized fatty acid esters in which the ring opening has been carried out while maintaining the ester bond .

- Such products can be produced by known epoxidation and ring opening processes.
- Ring opening and transesterification products are preferred in which a ratio between epoxidized fatty acid ester and the alcohol used for the reaction of 1: 0.5 to 1: 5 has been used.
- epoxidized fatty alcohols 1: 1 or 1: 2 adducts can also be produced here.
- Advantageous polyols are the reaction products of epoxidized fatty acid methyl ester with aliphatic C2 to Cg alcohols with functionality 2 to 4.
- All previously mentioned alcohol mixtures which can be used as polyol can still be subjected to a chain extension reaction. For this purpose, they are reacted with C2 to C / j epoxides under conditions known per se.
- the reaction with ethylene oxide is preferred here.
- the alcohol mixtures can be reacted with 1 to 40 moles of ethylene oxide per mole of 0H groups.
- the reaction with 5 to 20 mol and in particular with 10 to 15 mol of ethylene oxide is preferred.
- propylene oxide using up to 40 moles, preferably 5 to 20 moles, of propylene oxide per mole of OH group.
- other short-chain epoxides for example glycidol, can be used.
- butene oxide is a suitable reaction medium.
- the reaction with ethylene oxide and / or with glycidol leads to a hydrophilization of the hardener, which is desirable for some applications.
- the isocyanate component of the casting resins according to the invention is an isocyanate compound with functionality 2 to 4. Both aromatic and aliphatic, monocyclic and polycyclic, polyfunctional isocyanate compounds are suitable here.
- tolylene diisocyanate or diphenylmethane diisocyanate can be used as the aromatic isocyanate compound.
- Technical diphenylmethane diisocyanate with a content of higher functional diisocyanates and a functionality of isocyanate groups greater than 2 is particularly suitable.
- aromatic diisocyanate is xylylene diisocyanate.
- aliphatic isocyanates with functionality 2 and higher can be used. Examples are isophorrone diisocyanate, tris (6-isocyanatohexyl) isocyanurate and dicyclohexylmethane diisocyanate as cyclic aliphatic diisocyanates.
- aliphatic, straight-chain diisocyanates such as those obtained by phosgenation of diamines, for example tetramethylene diisocyanate or hexamethylene diisocyanate.
- prepolymers can also be used.
- Prepolymers are understood here to mean the adducts of polyfunctional isocyanates with polyfunctional alcohols, for example the reaction products of one of the aforementioned aromatic or aliphatic diisocyanates with ethylene glycol, propylene glycol, glycerol, trimethylolpropane or pentaerythritol.
- Reaction products of diisocyanates with polyether polyols for example polyether polyols based on polyethylene oxide or based on polypropylene oxide, can also be used as prepolymers.
- cyclic prepolymers made from diisocyanates can also be used, for example isocyanurates.
- the two-component casting resins and coating compositions can furthermore contain various auxiliaries, which are preferably added to the polyol.
- Fillers for example, can be used here. Suitable fillers are inorganic compounds which are not reactive toward isocyanates, such as chalk or gypsum, precipitated silicas, zeolites, bentonites, ground minerals and other inorganic fillers known to the person skilled in the art.
- Organic fillers can also be used, in particular fiber short cuts and others. Fillers are preferred which impart thixotropy to the casting resins.
- the two-component casting resins or coating compositions according to the invention can also contain accelerators.
- Suitable are, for example, tertiary bases such as bis (N, N-dimethylamino) diethyl ether, dimethylaminocyclohexane, N, N-dimethylbenzylamine, N-methylmorpholine and the reaction products of dialkyl ( ⁇ -hydroxyethyl) amine Monoisocyanates and esterification products of dialkyl (ß-hydroxyethyl) amine and dicarboxylic acids.
- Another important accelerator is 1,4-diamino-bicyclo- (2.2.2) octane.
- non-basic substances can be used as accelerators.
- Metal compounds may be mentioned here, for example iron pentacarbonyl, nickel tetracarbonyl, iron acetylacetonate and tin (II) - (2-ethylhexoate), dibutyltin dilaurate or molybdenum glycolate.
- the casting resins or coating compositions may also contain other auxiliaries.
- Solvents should be mentioned here. Solvents which in turn do not react with isocyanate groups are suitable, for example halogenated hydrocarbons, esters, ketones, aromatic hydrocarbons and others. Plasticizers, Flame retardants, retarders, dyes and anti-aging agents, as are known in corresponding casting resins, can be co-worked.
- the polyols used according to the invention can be replaced by other polyols to an extent of up to 80%. However, they are preferably used unmixed.
- the isocyanate casting resins or coating compositions are stored in two components until they are used, that is to say up to this point in time the polyol and isocyanate compound are stored separately. For use, these two compounds are mixed with one another and the mixture is applied to the substrates to be bonded.
- mixing ratio and measures to influence the pot life please refer to the general specialist knowledge of the person skilled in the art. This is documented, for example, in the monograph by Saunders and Frisch “Polyurethanes, Chemistry and Technology", Volume XVI of the series High Polymers "Interscience Publishers” New York - London, Part I (1962) and Part II (1964).
- the person skilled in the art will generally strive for equivalence of isocyanate and OH groups.
- the OH number of the alcohol mixtures and the isocyanate number of the isocyanate compounds can be determined in preliminary tests, from which the number of moles of reactive groups per gram can then be calculated.
- Particularly suitable polyols according to the invention have OH numbers between 120 and 400, preferably between 150 and 380.
- compounds with a lower or higher OH number for example with OH numbers between 60 and 120 or between 240 and 500, are also suitable, provided that their functionality is not below two OH groups per molecule.
- the casting resins or coating compositions prepared according to the invention are largely inert to moisture and even to water. It is thus possible to use them for moist substrates made of, for example, wood or textiles. In addition, they are also resistant to aggressive media such as salt solutions, inorganic or organic acids - for example acetic acid -, alkalis, organic solvents and ester oils on an organic basis, for example synthetic esters such as rapeseed oil methyl ester and lubricant ester.
- the resins and compositions are therefore suitable for use in the chemical industry, in the electrical and mineral oil industry and, for example, in bathrooms, in model making and in facades, in particular in concrete renovation and painting, and for corrosion protection. Tough, impact-resistant, flexible coatings can be produced.
- the cured compact polyurethanes are also transparent.
- PUR test specimens (diameter 5 cm) were produced from the polyols and Desmodur VKS (isocyanate from Bayer), then cured for 24 h at room temperature (approx. 23 ° C) and 2 d at 80 ° C. Recipe: 20 g polyol
- test specimens were stored at 80 ° C. in 20% potassium hydroxide solution and the mass and / or the Shore hardness were determined at intervals.
- Castor oil 70A decay 1 b) weight loss as a function of time (weight in g)
- MDI methane diphenyl diisocyanate
