摘要
An environment-protecting polyurethane (PU) composition especially used for environmental-friendly synthetic leather, a synthetic leather and a preparation thereof. A PU composition used for environmental-friendly synthetic leather comprises the following components: polyurethane resin 35-60%, carbon powder 10-35%, coagulator 0.8-3%, N,N-dimethylformamide 1-10% and acetone 15-35%, based on the weight percent. Furthermore, 1-12% functional nano material is added. In the invention, according to the above mentioned embodiment, carbon powder is used in place of lignin that was used in the past, so that harmful substances and gases in the formulawere adsorbed by the carbon powder during agitation in the dosing stove. It is advantageous for environment-protection and workers' health. In the meantime, the intrinsic function of carbon powder was exerted sufficiently in synthetic leather through the combination of carbon powder and synthetic leather. The invention further provides synthetic leather made of the PU composition used for synthetic leather and preparation thereof.
