The temperature adopted by the hot pressing is set to be 110-135 ℃, the pressure is set to be 11-17 MPa, and the hot pressing time is 1200-1600 seconds. Preferably, the temperature used for the hot pressing is set to 115, 120 or 125 degrees, the pressure can be set to 12, 13, 14, 15 or 16 mpa, and the hot pressing time can be set to 1300, 1400, 1500 or 1580 seconds.
Preferably, after the hot pressing operation is completed, the semi-finished product/finished product of the decorative board may be subjected to a cooling process, that is, after step S5 is completed, before step S6 is performed, the semi-finished product (only one surface is manufactured) of the decorative board is cooled, and after step S7, the finished product (both surfaces are processed) of the decorative board is cooled, so as to prevent the semi-finished product/finished product of the decorative board from being deformed due to an excessive temperature difference between the semi-finished product/finished product of the decorative board and the outside. The preferred adopts the mode of mechanical cooling to the cooling is more even, can not lead to the decorative board to warp because of the cooling is inhomogeneous. The specific cooling degree is determined according to the ambient room temperature at that time, and the temperature difference can be no more than 60 ℃.
In this embodiment, the hot pressing operation may be performed in a hot press, and after the hot pressing operation is completed, the temperature in the hot press is reduced, and in this cooling process, the semi-finished product or the finished product of the decorative plate in the hot press is also cooled along with the temperature. In order to balance the manufacturing efficiency and the quality of the semi-finished product or the finished product of the decorative plate, the temperature is generally reduced to a temperature which is not higher than 60 ℃ with the hot pressing temperature.
