The invention provides a PVC foam composite board and a production method and application thereof. An upper base and / or one surface of a PVC foam board is glued; the upper base and the PVC foam board are adhered through the glued side; the upper base and the PVC foam board are pressed to prepare the expanded PVC material composite board. The PVC expanded plastic composite board provided by the invention has low density, high strength, good adhesion between the layers, heat and sound insulation, and flame retardant properties. Due to the small density of the composite board, two simple usage methods can be employed: one is to directly combine the composite board with the matrix by a nail-free glue; and the other is to coat a proper adhesive on the back of the matrix, so that users can directly apply the composite board to the matrix (such as a wall) subjected to certain treatment by themselves. The composite board is simple for installation and convenient for operation, so it has excellent usage properties and processing performances, and has obvious advantages compared with the existing wall decorative materials.

The lightweighthigh-strength microcrystal ceramic insulation board is prepared by the following steps of: mixing and crushing waste minerals, a foaming agent and a sintering modifier; mixing the crushed mixture with the nucleating agent; after ball-milling, filter-pressing, pelleting and staling the mixture, directly paving the powder in a fire-resistant mould fully, scraping the mould smoothly and allowing themould to enter a kiln; and after performing high-temperature sintering, quick cooling, nucleating treatment, quick heating and crystallization, cooling again and then annealing to prepare the product. The lightweight high-strength microcrystal ceramic insulation board has the advantages that: the average grain diameter is between 0.5 and 5 mu m; and crystal grains are dense and uniformly distributed and develop well.
