Decorative laminate with layered structure and specific fillers
The granted patent US12036779B2 describes a decorative laminate created by pressing a decorative layer and a core layer together under heat. The decorative layer consists of decorative paper and a thermosetting resin, while the core layer is made from a prepreg that includes a fibrous base material and a slurry. The slurry contains an organic resin component and an inorganic filler, which can include endothermic metal hydroxide and/or other inorganic substances. The fibrous base material is a nonwoven fabric with entangled fibers and voids, bound by a thermoplastic resin emulsion. The inorganic filler is characterized by a specific particle size distribution, with average diameters categorized into small, medium, and large particles, and a defined blending mass ratio among them.
Further claims detail the composition and properties of the core layer, including the blending ratio of the organic resin to the inorganic filler, the maximum sectional height in waviness curves, and specific materials for the fillers, such as calcium carbonate and aluminum hydroxide. The patent also specifies the mass per unit area for both the inorganic filler and the organic resin component, as well as the potential for the decorative laminate to be non-combustible. Additional measurements related to particle size distribution and specific surface area of the inorganic filler are also outlined, emphasizing the laminate's structural characteristics and performance attributes.
