Problems solved by technology

[0002] Foaming materials have good cushioning properties and are widely used. At present, PVC foaming materials are widely used decorative papers, but the types of decorative papers manufactured by PVC foaming processing are relatively single, and the chemical foaming agents used are in the The decomposition is not complete during the foaming process, leaving residues in the base material, which not only affects the performance of decorative paper products, but also easily causes environmental pollution
It cannot meet the diverse needs of people. For example, when used as interior materials or packaging materials, people require decorative paper to be flame-retardant, mildew-proof, anti-bacterial, sound-proof, heat-insulating, moisture-proof, and waterproof in addition to being beautiful and environmentally friendly. function, and at the same time have softness, improve the safety of the application, this kind of composite functional decorative paper is rare

Abstract

The invention discloses a soft environment-friendly multifunctional decorative paper and a preparation method thereof. The decorative paper has a layered structure and comprises a hot laminated layer A (2), a foamed sheet layer (3), a hot laminated layer B (4), and a substrate layer (5) from top to bottom. A patterned layer (1) is printed and / or pressed on the surface of the hot laminated layer A (2). Through the requirements on surface density, porosity, aperture, foaming ratio, and compression stress of foamed sheet layer, the substrate layer and the foamed sheet layer are directly laminated by a hot lamination technology, thus the phenomenon that the structure and performance of the foamed sheet layer are damaged by the patterned layer is avoided, the prepared decorative paper has the flame-retardant, mold-resistant, antibacterial, soundproof, heatproof, dampness-resistant, and waterproof functions, at the same time, the decorative paper is soft, and the application safety is improved therefore.
