Title:
可撓性のある複合エラストマーポリウレタンスキンの製造方法
Document Type and Number:
Japanese Patent JP5596973
Kind Code:
B2
Abstract:
The present invention relates to a method for producing a flexible elastomeric composite polyurethane skin wherein a polyurethane reaction mixture is sprayed onto a mould surface and the polyurethane reaction mixture is allowed to cure to produce the skin layer. The polyurethane reaction mixture is composed of components comprising at least an isocyanate component, isocyanate-reactive components and a catalyst component and the isocyanate component is composed of at least one isocyanate having at least two NCO-groups which are not directly attached to an aromatic group. The catalyst component is substantially free of lead, which leads to a lower flexibility. In accordance with the invention, the flexibility of the polyurethane skin is increased by means of at least one flexibiliser which reduces the flexural modulus of the skin and which comprises at least one isocyanate-reactive group. The flexibiliser is preferably a monofunctional flexibiliser which comprises only one isocyanate-reactive group.
