[0073] Example 1: Production of laminates:

[0074] For the production of laminates, the following polyurethane reaction systems are used:

[0075] Polyol Formulation (Component A):

[0076] 70.30 parts by weight of a polyether polyol starting from glycerol, having a number-average molar mass of 6011 g / mol, comprising 82.3 wt.% PO and 17.7 wt.% terminal EO blocks,

[0077] 20.00 parts by weight of polyoxypropylene polyols, starting from trimethylolpropane, having a number-average molar mass of 306 g / mol,

[0078] 7.00 parts by weight 1,4-butanediol,

[0079] 2.00 parts by weight of a polymerization catalyst that can be incorporated (Bayfill® Additive VP.PU59IF08, Bayer AG)

[0080] The polyol formulation has an OH value of 221.

[0081] Isocyanate component (component B):

[0082] Crude MDI, comprising 1-5 wt.% 2,4'-MDI, 44-55 wt.% 4,4'-MDI and 40-55% polymethylene poly(phenylisocyanate).

[0083] The foaming ratio of component A:component B is 100:52 parts, correspond...

Abstract

The present invention relates to laminates comprising metal and compact or cellular polyurethane resins, to processes for the production of these laminates, and to the production of molded articles comprising these laminates.

Description

technical field [0001] The present invention provides laminates consisting of metal and dense or cellular polyurethane resins and processes for their production. Background technique [0002] Laminates consisting of steel and polypropylene have been used in the construction of automobiles, for example, for fender trays, roof panels, instrument panels, skin components, covers, and the like. Here, due to the thermoplastic lining material, the heat resistance is still insufficient in many cases; furthermore, considerable expenditure is required to obtain a sufficiently strong polypropylene-steel bond. [0003] WO 98 / 21029 discloses laminated sandwich elements for shipbuilding in which two steel plates are bonded together by a polyurethane elastomer core. The steel plate has a thickness of 6-25mm; the polyurethane elastic body has a tensile strength of 20-55MPa, a flexural modulus of 2-104MPa, an elongation of 100-800% and a hardness of Shore 70A to Shore 80D. [0004] WO 99 / 6...
