    摘要： Natural Marble and Natural Granite, being used in civil construction, are finite resources not perpetually available. There have been attempts to match the attributes of natural marble and granite by artificial processes and at less expense. Though these products closely resemble natural stones, the processes used in manufacturing these articles are slow, and they are difficult to recycle due to the fact that they are made using a combination of different materials. The present invention provides a method for preparing composite board in polypropylene and digitally printing & coating it externally to provide aesthetics and required hardness. The method comprises corona treatment; applying and drying a primer; applying and curing base coat on the dried surface; sanding of the board using fine emery boards; digitally printing and curing the sanded board; application and curing of a primer; and coating and curing to gain surface hardness, abrasion resistance, scratch resistance, fire resistance and gloss.

    摘要翻译： 天然大理石和天然花岗岩，用于民用建筑，是永久可用的有限资源。 已经尝试通过人造过程和较少的费用来匹配天然大理石和花岗岩的属性。 虽然这些产品与天然石材非常相似，但是用于制造这些制品的方法很慢，并且由于它们是使用不同材料的组合制成的，所以它们难以回收。 本发明提供了一种在聚丙烯中制备复合板的方法，并在外部进行数字印刷和涂层以提供美观和所需的硬度。 该方法包括电晕处理; 施用和干燥底漆; 在干燥的表面上涂覆和固化底漆; 使用精美砂纸打磨板; 数字打印和固化砂光板; 底漆的施用和固化; 并涂覆和固化以获得表面硬度，耐磨性，耐刮擦性，耐火性和光泽。
