    • PURPOSE: A method for preparing a polymer composite material using natural stones is provided to reinforce chemical resistance and staining resistance and to prevent deformation due to the load. CONSTITUTION: A method for preparing a polymer composite material comprises: a step of pulverizing natural stones to prepare natural stone powder of a powder or chip form; a step of mixing 2-8 weight parts of thermosetting resin based on 92-98 weight parts of natural stone powder, 30-100 weight parts of filler, 0.01-2 weight parts of hardener, 5-20 weight parts of polystyrene low-contracting agent, and 0.1-5 weight parts of thickener based on 100 weight parts of thermosetting resin; a step of thickening at room temperature for 10-30 hours; and a step of extruding and curing at 100-200°C and 5,000-10,000 kgf/cm^2 for a minute to one hour.
    • 目的:提供使用天然石料制备聚合物复合材料的方法,以增强耐化学性和耐污染性,并防止由于载荷引起的变形。 构成:制备聚合物复合材料的方法包括:将天然石料粉碎以制备粉末或碎屑形式的天然石粉的步骤; 混合2-8重量份热固性树脂,基于92-98重量份天然石粉,30-100重量份填料,0.01-2重量份硬化剂,5-20重量份聚苯乙烯低收缩 基于100重量份热固性树脂的0.1-5重量份增稠剂; 在室温下增稠10-30小时的步骤; 以及在100-200℃和5,000-10,000kgf / cm 2 2下挤出和固化一分钟至1小时的步骤。
