Two-component Polyurethane Adhesive for Gluing Fibre Mouldings |
| 摘要 |
Disclosed is a 2-component polyurethane adhesive containing
a) 2 to 30% by weight of at least one oleochemical polyol having a molecular weight of greater than or equal to 500 g/mol,b) 5 to 35% by weight of at least one 3 to 14 functional polyol,c) 5 to 35% by weight of at least one polyol on the basis of ethoxylated or propoxylated polyphenols,d) 0 to 20% by weight of at least one further polyol,e) 2 to 65% by weight of at least one further additive, wherein the sum of a) to e) should be 100% by weight,as well as an isocyanate component containing at least one aromatic and at least one aliphatic polyisocyanate in an NCO/OH ratio of 0.9:1 to 1.5:1,wherein the cross-linked adhesive has a Tg of greater than or equal to 65° C.;Further, the use of such adhesives is described. |
