An organic glass includes an acrylic plate, a methyl methacrylate layer, and a fluorescent bubble layer that are sequentially stacked; and the fluorescent bubble layer is prepared from fluorescent polymethyl methacrylate beads, a first methyl methacrylate prepolymer and a second methyl methacrylate prepolymer. The fluorescent polymethyl methacrylate beads added into the raw material of the organic glass have an expandable characteristic, and can generate bubbles according to a design pattern to achieve the purpose of controllable bubbles, and the added fluorescent polymethyl methacrylate beads show fluorescent green under ultraviolet irradiation, giving bubbles a fluorescent color, and enabling the organic glass to have extremely artistic and decorative effects.

Organic glass, and preparation method and use thereof

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.

Some embodiments of the disclosure provide a toughened TiAl-based alloy sheet with periodically misaligned through-hole titanium alloy layers sequentially stacked together. A through structure is formed in the misaligned through-hole titanium alloy layer. Two openings of the through structure are respectively located on upper and lower surfaces of the titanium alloy layer. The misaligned opening position of the through structure is at a center position of a quadrangle formed by every four through holes in adjacent titanium alloy layers. The through structure is filled with a TiAl-based alloy. The TiAl-based alloy layers on adjacent sides of the titanium alloy layer are connected through the TiAl-based alloy in the through structure. The TiAl-based alloy layer is connected to the titanium alloy layer through a TiAl interface layer. The TiAl-based alloy and the titanium alloy in the through structure are connected through a TiAl interface layer.
