| titleOfInvention | Preparation method organic silicon-modified polyurethane resin for synthetic leather |
| abstract | The invention designs organic silicon-modified polyurethane resin for synthetic leather and a preparation method thereof, which relates to the field of processing of the synthetic leather and aims at solving the technical problems of poor anti-sticking property, water resistance, wear resistance and other properties of the existing synthetic leather. The organic silicon-modified polyurethane resin disclosed by the invention is characterized by comprising the following raw material ingredients in percentage by weight: 2%-30% of diisocyanate, 5%-40% of polyester or polyether type polylol, 0.5%-20% of hydroxyl-terminated organic silicon, 0%-10% of small molecular polylol chain extender, 0%-13% of small molecular polyamine chain extender, 0.01%-1% of catalyst and the balance of solvent, wherein the hydroxyl-terminated organic silicon adopts a polyether-polysiloxane copolymer with two ends which are of hydroxyl groups, and a polyether chain segment is of polyoxyethylene or polyoxypropylene. The glossiness and transparency of the polyurethane resin after modification can not be affected by the organic silicon, and the anti-sticking property, surface smoothness, wear resistance and water resistance are obviously improved simultaneously. |
