Problems solved by technology

[0006] A large number of bubbles in the foamed material is the key to reduce its density, but in the process of preparing composite materials with sandwich structure, how to avoid the collapse and compression of the bubbles, resulting in a large increase in density is a problem that needs to be solved
Existing methods to solve this problem, one is to directly bond with glue (bonding agent), the adhesion between the layers of the composite board prepared by this method is poor, and it is easy to fall off; the other method is to press and form Then foaming, this method has poor adaptability and can only produce pre-designed single products

Abstract

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.

Description

technical field [0001] The invention relates to a composite board and a preparation method thereof, in particular to a PVC foamed plastic composite board, a preparation method and application thereof. Background technique [0002] Foamed plastics (foamed plastics) have excellent impact resistance, good thermal and sound insulation properties, and excellent processing and molding properties, so they are usually used in sound insulation materials, packaging shock absorption materials, etc. At present, the composite materials of the foam sandwich structure generally use foam plastic as the foam core, which has high strength, low density and high rigidity, and is widely used in various fields. [0003] Common foamed plastics are mainly polyurethane, polystyrene and polyethylene foamed plastics, such as flexible or rigid polyurethane foamed plastics disclosed in patent documents US2009234036A1, JP2004-75700A, WO2001 / 096434A, EP0830419B1, polyethylene-polystyrene disclosed in CN10...
