Description

Stabilization of polyether polyol, polyester polyol or polyurethane compositions

The present invention relates to compositions comprising polyether polyols, polyester polyols or polyurethanes (which are sensitive to light-induced degradation) and at least two different light stabilizers (one of which is a specific UV- absorbers and/or hindered amine light stabilizers). the

DE 10148702A1 relates to a stabilizer blend comprising antioxidants, HALS compounds, UV-absorbers and phosphorus compounds. The initial yellowness of the thermoplastic polyurethanes stabilized with the above blends of stabilizers is not particularly great. the

WO 03/095543 relates to stabilizer mixtures for polymer substrates comprising benzylidene-bis-malonate and at least one selected from UV-absorbers, hindered amine stabilizers, sterically hindered phenols, organic phosphine , organic phosphite and organic phosphonite (phosphonite) compounds. The stabilizer mixture described above provides protection to the polymeric substrate against the damaging effects of light exposure caused by long-term storage of the polymer. the

There is a strong need in the polyurethane industry for systems with excellent initial color and good lightfastness. This is of particular importance for the shoe industry, where good color stability is required, for example, for thermoplastic polyurethanes (TPU). Furthermore, there is a need for non-yellowing or low-yellowing polyurethane hot melt adhesives and silylated polyurethane (SPUR) sealants and artificial leather, especially based on aromatic isocyanates. the

The polyether polyols, polyester polyols or polyurethane compositions according to the invention have an excellent initial color after processing, good light stability and good resistance to gas fading. the

The present invention relates to a composition comprising

(a) polyether polyol, polyester polyol or polyurethane,

(b) UV-absorbers of general formula (I) and/or hindered amine light stabilizers of general formula (II)

Wherein R ₁ and R ₂ are each independently C ₁ -C ₄ alkyl or C ₁ -C ₄ alkoxy,

and

The mentioned stabilizers and stabilizer blends are suitable as stabilizers for polyether polyols, polyester polyols or polyurethanes against oxidative, thermal and/or light-induced degradation and as polymer fogging contribution) reducer. the

The polyether polyols, polyester polyols or polyurethane compositions of the present invention can also be foams (flexible, rigid, monolithic), microcellular foams, cast PU, PU skins, PU hot melt adhesive agent, silylated polyurethane (SPUR), thermoplastic polyurethane (TPU), PU elastomer, artificial leather, PU skin, PU stray coating or reaction injection molded part (RIM). the

For example, the polyether polyol, polyester polyol or polyurethane compositions of the invention are unfoamed. the

Polyurethanes are obtained, for example, by the reaction of polyethers, polyesters and polybutadienes (which contain terminal hydroxyl groups, ie polyols) with aliphatic or aromatic polyisocyanates. the

Polyethers and polyesters with terminal hydroxyl groups are known, for example by making epoxides (such as ethylene oxide, propylene oxide, butylene oxide, tetrahydrofuran, styrene oxide or epichlorohydrin) themselves in e.g. BF ₃ in the presence of polymerization to prepare, or by these epoxides individually, in admixture or continuously with active hydrogen atom-containing starting components (such as alcohols, ammonia or amines, such as glycol, 1,3- and 1,2-propanediol, trimethylolpropane, 4,4'-dihydroxy 1,3-diphenylpropane, aniline, ethanolamine or ethylenediamine) addition reaction to prepare. Sucrose polyethers are also suitable according to the invention. Preferred in many cases are those polyethers containing predominantly primary hydroxyl groups (up to 90% by weight, based on the hydroxyl groups present in the polyether). Furthermore, polyethers modified from vinyl polymers, formed for example by polymerizing styrene and acrylonitrile in the presence of polyethers, are also suitable (hydroxyl-containing polybutadiene).

These compounds usually have a molecular weight of 40 and are polyols, especially those containing 2-8 hydroxyl groups, especially those with a molecular weight of 800-10000 (preferably 1000-6000), for example containing at least 2, usually 2-8 Polyethers having one, but preferably 2 to 4, hydroxyl groups are known for the preparation of homogeneous and microcellular polyurethanes. the

It is of course possible to use mixtures of the aforementioned compounds containing at least 2 isocyanate-active hydrogen atoms, in particular having a molecular weight of 400-10,000. the

Suitable polyisocyanates are aliphatic, cycloaliphatic, araliphatic, aromatic and heterocyclic polyisocyanates, such as ethylene diisocyanate, 1,4-butanediisocyanate, 1,6-hexamethylene diisocyanate, 1,12 - dodecane diisocyanate, cyclobutane 1,3-diisocyanate, cyclohexane 1,3- and -1,4-diisocyanate and any desired mixtures of these isomers, 1-isocyanato-3 , 3,5-trimethyl-5-isocyanatomethylcyclohexane, 2,4- and 2,6-hexahydromethylphenylene diisocyanate and any desired mixtures of these isomers, Hexahydro-1,3- and/or-1,4-phenylene diisocyanate, perhydro-2,4'- and/or-4,4'-diphenylmethane diisocyanate, 1,3- and 1, 4-phenylene diisocyanate, 2,4- and 2,6-tolylene diisocyanate and any desired mixtures of these isomers, diphenylmethane 2,4'- and/or -4,4' - diisocyanates, naphthylene 1,5-diisocyanate, triphenylmethane 4,4',4"-triisocyanate, such as polyphenylene-polymethylene polyisocyanates obtained by aniline-formaldehyde condensation followed by phosgenation, m- and p-isocyanatobenzenesulfonyl isocyanates, perchlorinated aryl polyisocyanates, polyisocyanates containing carbodiimide groups, polyisocyanates containing allophanate groups, isocyanurates Polyisocyanates containing ester groups, polyisocyanates containing urethane groups, polyisocyanates containing acylated urea groups, polyisocyanates containing biuret groups, polyisocyanates containing ester groups, and combinations of the above isocyanates and acetals reaction products, and polyisocyanates containing polymerized fatty acid groups. 

It is also possible to use distillation residues containing isocyanate groups (when they are or dissolved in one or more of the abovementioned polyisocyanates) which are obtained during the industrial preparation of isocyanates. It is also possible to use any desired mixtures of the aforementioned polyisocyanates. the

In general particular preference is given to polyisocyanates which are readily commercially available, such as aromatic isocyanates such as 2,4- and 2,6-tolylylene diisocyanate and any desired mixtures of these isomers (“TDI”), such as Polyphenylene-polymethylene-polyisocyanates (“crude MDI”) prepared by aniline-formaldehyde condensation followed by phosgenation, and compounds containing carbodiimides, urethanes, allophanates, isocyanurates, Polyisocyanates of urea or biuret groups (“modified polyisocyanates”). the

The polyurethanes are preferably prepared from liquid starting components, ie raw materials which are mixed with one another and reacted in a one-step process. the

The addition of additives and/or stabilizer blends to polyether polyols, polyester polyols or polyurethanes is carried out by known methods, for example before or during compounding, extrusion, coextrusion, also in Added before or during polymerization or before crosslinking. If additives and/or stabilizer blends are added prior to polymerization, they may be dissolved in one or all of the reactants. They are preferably dissolved in polyether polyols or polyester polyols. the

Kalahari exposure was carried out according to VW Test PV 3929 with a xenon exposure of 75 W/ ^m2 at λ = 300-400 nm.

Color measurement

The yellowness index (YI) is determined on TPU samples according to ASTM 1926-70 Yellowness Test, according to which the color quality is reported. A low YI value indicates little discoloration and a high YI value indicates severe discoloration of the sample. The whiter the TPU, the better the TPU stability. the
