B: preheating the obtained material, adding 6-8 parts of foaming agent when the temperature reaches 25-35 ℃, sealing the tank body, fully stirring for 1 hour, and then cooling the material for standby;
C: the cooled material is added into an aluminum casting mold in an integral casting mode, a plurality of ceramic columns (2) which are placed at equal intervals are fixed in the aluminum casting mold in advance through a fixed net (3), the thickness of each ceramic column (2) is two thirds of the thickness of the polyurethane lining plate after molding, and after the material is completely solidified and solidified, demolding is carried out, so that the polyurethane lining plate can be obtained.
