Disclosed is a micro-surfacing sealing coat mixture, comprising the following raw materials in parts by weight: 10-20 parts of a cationic emulsified asphalt, 5-7 parts of an ethylene-1-octene copolymer, 3-6 parts of an organic silicone resin, 8-12 parts of a filler, 80-90 parts of an aggregate, 2-4 parts of a ditertiarybutyl peroxide, 20-30 parts of water, and 0.5-2 parts of an accelerator. The method for preparing the micro-surfacing sealing coat mixture comprises: weighing raw materials other than the filler, aggregate and water, adding to a high-speed shear emulsifier and mixing at a temperature of 170-175° C. for 20-35 min, then continuously shearing at 3000-3500 r/min for 60 min to obtain a modified emulsified asphalt; cooling the modified emulsified asphalt to 20-30° C., adding the filler, aggregate and water thereto, and adding the resulting mixture to a mixer to mix evenly to obtain the micro-surfacing sealing coat mixture.

The present invention discloses a preparation method for a surface molding film of a PVC-based stone plastic composite board, including: surface activation treatment of the PVC-based stone plastic composite board: preparation of an activated putty, coarse roughening of a substrate surface, application and solidification of the activated putty, and fine roughening of the substrate surface; preparation of a PMMA slurry; and surface film forming of the PVC-based stone plastic composite board. The PVC-based stone plastic composite board coated with a PMMA film is obtained by cold pressing and shaping in a mold, tightening up a clamp, solidifying at low temperature, treating at high temperature, cooling and demolding. The PVC-based stone plastic composite board coated with the PMMA film prepared by the present invention can avoid the problems of large investment in production lines and equipment and high production costs involved in the production of floorboards by the conventional surface printing and surface laminating technologies, to partially replace composite floorboards, stone, acrylic panels, and curtain wall panels, etc. currently popular in the market, and provide a new path for the high additional utilization of waste.
