Description
技术领域
本发明涉及建筑材料制备技术领域，特别是一种石墨烯人造石。
背景技术
在中国飞速发展的家居业，石英石材作为一种新型高分子复合材料，除了作为橱柜行业的配套产品外，在整个行业应用日趋广泛。石英石是不饱和聚酯树脂重要应用领域。石英石的板材被广泛用于橱柜台面、卫生间台面、餐桌台面、医院台面和实验室台面等。
石英石由90％以上的天然石英和10％左右的色料、树脂和其它调节粘接、固化等的添加剂组成，是经过负压真空、高频振动成型，加温固化(温度高低是根据固化剂的种类而定的生产方法加工而成的板材。其质地坚硬(莫氏硬度5-7)、结构致密(密度2.3-2.5g/立方厘米) 具有其他装饰材料无法比拟的耐磨、耐压、耐高温、抗腐蚀、防渗透等特性。但是也由于其配方材料和加工工艺决定其材料质感接近石头，属于脆性高分子复合材料，因此很容易在加工使用过程中，由于一些不当外力和冷热内应力原因导致其开裂，影响其持续使用。
发明内容
针对现有技术中存在的不足之处，本发明提供一种石墨烯人造石，采用如下技术方案：
