摘要： A color stabilized composite material combines polymers with cellulosic natural fibers or wood or wood based composite materials to manufacture an array of products for both indoor and outdoor applications. The invention provides the means to enhance the color stability of such products from the negative effects of ultraviolet radiation and weather in addition to improving the physical properties of the overall fiber-polymer matrix. In one aspect, the invention provides a composite material including a natural fiber, such as wood flour, and a polymer resin, wherein the natural fiber has been pretreated with a bleaching or oxidizing agent. In another aspect, the invention provides a color stabilized composite building material including an elongated substrate, and a thermoplastic material coating disposed on a longitudinal circumference of the substrate, which may be wood or a wood-based composite material such as plywood, cellulosic fiberboard, particle board, waferboard, flakeboard, chipboard, or oriented strand board.
摘要翻译：颜色稳定的复合材料将聚合物与纤维素天然纤维或木材或木基复合材料结合，以制造用于室内和室外应用的产品阵列。本发明提供了除了改善整个纤维聚合物基体的物理性能之外，还可以增强这些产品从紫外线和天气的负面影响的颜色稳定性的方法。一方面，本发明提供了包括天然纤维如木粉和聚合物树脂的复合材料，其中天然纤维已用漂白或氧化剂预处理。另一方面，本发明提供了一种颜色稳定的复合建筑材料，其包括细长基材和设置在基材的纵向圆周上的热塑性材料涂层，其可以是木材或木基复合材料，例如胶合板，纤维素纤维板，刨花板，刨花板，刨花板，刨花板或定向刨花板。
