    • 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.
    • 公开了制备高分子层压体的方法。 首先,制备高固含量聚氨酯树脂。 高固含量聚氨酯树脂的固含量高于80重量%,粘度为20000至60000cps / 30℃。高固含量聚氨酯树脂在室温下为液体。 将高固含量的聚氨酯树脂与添加剂混合以形成固体含量高于50重量%,粘度为20000至60000cps / 30℃的第一种聚氨酯树脂化合物。第一种类型的聚氨酯树脂化合物 在室温下为液体,在室温下具有至少3小时的适用期。 将第一种类型的聚氨酯树脂化合物涂覆在脱模纸上以制成主层。 然后,将脱模纸从主层移除以制成层压体。
