摘要
A method for manufacturing ecotypic artificial leather or leather-like includes the following steps: a first step of forming a surface layer; a second step of spray foaming which is to coat the partly cured surface layer with a reactive solvent-free multicomponent polymer using a multicomponent reaction injection molding device and a spray gun; a third step of once-molding roller pressing which is to press the substrate, foaming layer, surface layer and release paper together between the multicomponent polymer foaming stage and curing stage using a roller press device; and a fourth step of maturing and stripping, in which the substrate, foaming layer, surface layer and release paper are heated up, and then are cooled down while the release paper is removed. The production process utilizing the manufacturing method described in this invention is totally environmentally friendly. The physical and chemical properties of the product are excellent. The equipment utilized has high degree of automation and is easy to industrialize.
