Abstract
In the method according to the invention, a layer of polyurethane elastomer for obtaining a polyurethane skin (5) is produced, in a first step, against a mould surface (1). In a second step, a reaction mixture for obtaining a polyurethane foam layer (6) is applied against this polyurethane skin (5). In a third step, a suitable polyurethane or polyisocyanurate reaction mixture for obtaining a rigid synthetic carrier (8) is applied against the polyurethane foam layer (6). In this way, a synthetic trim part is obtained which is easier to recycle. This method can moreover also be performed easier.
Claims23
A method for manufacturing a self-supporting synthetic trim part having a leatherlike touch and including an elastomeric polyurethane skin, a rigid synthetic carrier and a mainly open-cell polyurethane foam layer therebetween, said method comprising applying, in a first step, an elastomeric polyurethane skin having a thickness of from 0.3 to 1.3 mm of a polyurethane elastomer against a mold surface;
- applying, in a second step, by spraying against said elastomeric polyurethane skin, a reaction mixture for obtaining a mainly open-cell polyurethane foam layer having a thickness of from 1 to 7 mm and an integral skin thereon opposite said elastomeric polyurethane skin;
- and applying, in a third step, a suitable polyurethane or polyisocyanurate reaction mixture for obtaining a rigid synthetic carrier against said integral skin of said polyurethane foam layer.
