摘要: A method for making a macromolecular laminate is disclosed. Firstly, a high solid-content polyurethane resin is prepared. The high solid-content polyurethane resin has a solid content higher than 80% by weight and a viscosity from 20000 to 60000 cps/30° C. The high solid-content polyurethane resin is liquid at the room temperature. The high solid-content polyurethane resin is mixed with additives to form a first type of polyurethane resin compound with a solid content higher than 50% by weight and a viscosity from 20000 to 60000 cps/30° C. The first type of polyurethane resin compound is liquid at room temperature and has a pot life of at least three hours at room temperature. The first type of polyurethane resin compound is coated on a releasing paper to make a main layer. Then, the releasing paper is removed from the main layer to make a laminate.
