摘要： A die-formed chamfered plastic floor and a preparation method thereof are disclosed. The method includes: mixing raw materials for preparing a plastic floor matrix to obtain a mixed material; subjecting the mixed material to an extrusion, a laminating-embossing treatment, a die forming-chamfering treatment, a coating with an ultraviolet curable paint, a slicing, and a tenoning in sequence, to obtain the die-formed chamfered plastic floor. In the disclosure, a die forming-chamfering treatment is set between a laminating-embossing treatment and a coating with an ultraviolet curable paint, and thereby a chamfer embossing could be formed on the surface of the workpiece through pressing.

摘要： The disclosure belongs to the technical field of floor preparation, and provides a method for treating a surface of a floor. Compared with traditional methods for preparing floor, in the method according to the disclosure, an embossing is performed not directly after laminating, but after applying a wear-resistant primer, and a topcoat is then applied. Therefore, the resulting embossed floor has a clear texture. Further, the composition of the wear-resistant primer could be optimized, such that the resulting embossed floor exhibits excellent wear resistance and hardness.
