耐磨损装饰性层压板
摘要：
本发明提供具有改进的耐刮擦性和耐磨性的装饰性层压板。在一个实施例中，该装饰性层压板包括基板或芯板，基板上的装饰薄片，和该装饰薄片上的覆盖薄片。该覆盖薄片在两个主表面上进行涂覆，以使该层压板具有耐刮擦性和耐磨性。面向内的表面上的涂层含有具有大约10至30微米的颗粒尺寸的矿物颗粒。面向外的表面上的涂层含有第一矿物颗粒和第二矿物颗粒的混合物，该第一矿物颗粒具有大约3至8微米的颗粒尺寸，该第二矿物颗粒具有小于大约1.0微米的颗粒尺寸。该第一矿物颗粒最好为氧化铝颗粒，并且第二矿物颗粒最好为溶胶凝胶处理氧化铝颗粒。
摘要（英）：

A decorative laminate having improved scratch and abrasion resistance is provided. In one embodiment, the decorate laminate includes a substrate or core, a decorative sheet on the substrate, and an overlay sheet on the decorative sheet. The overlay sheet is coated on both major surfaces to provide scratch and abrasion resistance to the laminate. The coating on the interior facing surface containsmineral particles having a particle size of from between about 10-30 microns. The coating on the exterior facing surface contains a mixture of first mineral particles having a particle size of from between about 3-8 microns and second mineral particles having a particle size of less than about 1.0 micron. The first mineral particles are preferably alumina particles, and the second mineral particles are preferably sol gel process alumina particles.
