Definitions
- the present invention relates to blocked polyisocyanate crosslinking agents, their production and use in IK stoving lacquers, in particular OEM clear lacquers (original equipment material, first lacquering).
- blocked polyisocyanates are used as improving additives in 1-component stoving lacquers in automotive painting. With blocked polyisocyanates, demanding requirements for improved paint properties can be met relatively well. Other properties, such as a low baking temperature up to max. 140 ° C or low thermal yellowing when overburning, on the other hand, cannot be achieved with all available raw materials.
- the most important technical lacquer polyisocyanates are based on 1,6-diisocyanato-hexane (HDI).
- Blocking agents for polyisocyanates available on an industrial scale are malonic esters and 1,2,4-triazole, if deblocking temperatures of up to 140 ° C. are taken into account.
- the combination of HDI based polyisocyanates with Malonester or 1,2,4-triazole, or, as the following comparative example demonstrates, with a mixture of Malonester / 1 J, 4-tri ol *, does not lead to a useful shelf-stable and liquid Lackvernetzer because crystallize these products.
- the tendency towards crystallization of malonic ester-blocked HDI polyisocyanates is already known from EP-A 600 314, that of triazole-blocked polyisocyanates from EP-A 654 490 and 741 157.
- the object of the invention was to modify HDI-based polyisocyanates mixed-blocked with malonic ester and 1,2,4-triazole in such a way that liquid crosslinkers for IC baking lacquers which do not crystallize in solvents result. This problem was solved with the blocked polyisocyanates described below.
- the invention relates to aliphatic and / or cycloaliphatic polyisocyanates, the isocyanate groups of which
- blocked (reacted) are present, characterized in that they contain 0.05-1.0 mol of formaldehyde in the incorporated form, based on 100 equivalent% of blocked NCO groups.
- the invention also relates to a process for the preparation of the non-crystallizing blocked polyisocyanates according to the invention from
- the non-crystallizing blocked polyisocyanates according to the invention can preferably have a level of stabilizers against thermal yellowing of
- Such stabilizers are e.g. known from EP-A 829 500.
- the invention also relates to the use of the blocked polyisocyanates according to the invention as crosslinking agents for organic polyhydroxyl compounds in polyurethane stoving lacquers, for example for automotive clear lacquers.
- the content of formaldehyde is essential to the invention for the polyisocyanate crosslinking agents claimed.
- the formaldehyde surprisingly shows two modes of action: First, it prevents the crystallization of the blocked polyisocyanates, especially when the polyisocyanate component is based on HDI. On the other hand, it increases the resistance of the blocked polyisocyanates to thermal yellowing.
- Per 100 equivalent% blocked polyisocyanate 0J to 0.4 mol of paraformaldehyde are preferably used and reacted by means of a catalyst, such as Na methylate. This is approximately 0.8 to 5.0% by weight of formaldehyde, based on blocked polyisocyanate.
- the polyisocyanate component is optionally mixed with a little solvent, e.g.
- 1-methoxy-2-propyl acetate (MPA), initially charged at approx. 50 ° C, the CH-acidic ester, e.g. Malonic ester, is added as a mixture with about 2% of a 30% Na methylate solution and reacted at 70-90 ° C until the calculated NCO content. Then the calculated amount of 1,2,4-triazole, dissolved in further MPA, is added and the mixture is reacted at about 90 ° C., so that no more NCO groups can be detected. The batch is cooled to about 45 ° C.
- the CH-acidic ester e.g. Malonic ester
- the polyisocyanates on which the blocked polyisocyanates according to the invention are based are known lacquer polyisocyanates with aliphatic and / or cycloaliphatic and / or aromatically bound isocyanate groups and an isocyanate content of 7 to 30, preferably 12 to 25,% by weight.
- HDI 1,6-diisocyanatohexane
- IPDI 5-trimethyl-5-isocyanatomethyl-cyclohexane
- H 12 MDI or Desmodur W® / Bayer AG lacquer polyisocyanates containing allophanate and / or uretdione groups based on 1,6-diisocyanatohexane (HDI), l-isocyanato-3J, 5-trimethyl-5-isocyanatomethyl-cyclohexane (I
- asymmetrically trimerized lacquer polyisocyanates based on 1,6-diisocyanatohexane which in addition to isocyanurate also have iminooxadiazinedione groups, can be used as polyisocyanate components, as described, for example, in EP-A 798 299.
- Polyisocyanates based on other isocyanates such as e.g. 1,4-diisocyanato-butane, 2,4- or 2,6-diisocyanato-1-methyl-cyclohexane, 2,5- and / or 2,6-bis-isocyanato-norbornane, 3- and / or 4- Isocyanatomethyl-1-methylcyclohexane, 1,4-bis (2-isocyanato-prop-2-yl) benzene, 1J-diisocyanatomethylbenzene, 1, 3- or 1,4-bis-isocyanatomethylcyclohexane can be used.
- 1,4-diisocyanato-butane 2,4- or 2,6-diisocyanato-1-methyl-cyclohexane
- 2,5- and / or 2,6-bis-isocyanato-norbornane 3- and / or 4- Isocyanatomethyl-1-methylcyclohex
- isocyanurate group-containing polyisocyanates based on 1,6-diisocyanatohexane are very particularly preferred as the polyisocyanate component.
- CH-acidic esters come on the one hand as the blocking component
- 1,2,4-triazole is used in this mixed blocking. The latter can be obtained on an industrial scale from 1 mol of hydrazine hydrate and at least 2 mol of formamide.
- the CH-acidic esters or triazole can be used in amounts of
- Amounts of up to 50 equivalent%, preferably up to 20 equivalent%, can also be used as additional blocking agents: oximes, such as e.g. Butanone oxime, secondary amines, e.g. Diisopropylamine, NH-acidic heterocycles, e.g. Imidazole or 3,5-dimethylpyrazole or lactams, e.g. ⁇ -caprolactam.
- oximes such as e.g. Butanone oxime, secondary amines, e.g. Diisopropylamine, NH-acidic heterocycles, e.g. Imidazole or 3,5-dimethylpyrazole or lactams, e.g. ⁇ -caprolactam.
- the stabilizers known from EP-A 0 829 500 can be used as additional stabilizing components.
- the readily accessible hydrazide of the formula (Ia) which is readily accessible by adding hydrazine hydrate to 2 mol of propylene carbonate
- the first-mentioned stabilizer is preferably 3 to 6% by weight, the latter preferably 0.5 to 1.5% by weight, in each case based on blocked
- Solvents which are known from polyurethane chemistry and which are inert to NCO groups, for example 1-methoxy-2-propyl acetate, solvent naphta 100 or butyl acetate, can be used. If the NCO groups are blocked, alcohols, e.g. Isobutanol to enable transesterification with the alcohol residues of the blocking agent.
- This mixed-blocked polyisocyanate is stabilized with 3.0% of formaldehyde, based on the solids content of the blocked polyisocyanates.
- the ratio of the blocking agents for malonic ester: triazole 40:60 equivalent%, based on 100 equivalent% of NCO groups.
- HDI 1,6-diisocyanatohexane
- Polyisocyanate and methoxypropyl acetate are introduced and heated to approx. 50 ° C.
- Example 2 This example is similar in type and amount to Example 1 except that the modification of the blocked polyisocyanate with formaldehyde is omitted. The result is a product which begins to crystallize after one week of storage at room temperature. This blocked polyisocyanate can therefore not be used in storage-stable IC lacquer formulations.
- This mixed-blocked polyisocyanate is stabilized at 2.1%, based on the solids content of the blocked polyisocyanate. There are also two more
- Stabilizers (cf. EP-A 829 500 A2) mixed in the blocked polyisocyanate solution, namely 2.0% of a hydrazide which has already been explained and 1.0% of a HALS amine.
- NCO content of approx. 21%, a viscosity at 23 ° C of approx. 3,000 mPas and a functionality of approx. 3.5
- Solids content 70% blocked NCO content: 8.8% viscosity (23 ° C): approx.5,000 mPas Appearance: clear, Hazen 60
- the polyisocyanate and methoxypropyl acetate are presented. At about 50 ° C and with stirring, the mixture of diethyl malonate is carried with about 2%, ie. H.
- the crosslinker according to Example 3 becomes one with the following components
- This clear lacquer is applied to test panels that are coated with a commercially available white basecoat, e.g. from Spies & Hecker / Cologne, are applied in a wet layer thickness of approx. 120 to 150 ⁇ m and, as explained in the table below, baked and tested.
