Recyclable artificial marble and preparation method thereof
The invention belongs to the field of building decoration materials, and particularly discloses recyclable artificial marble and a preparation method thereof.The recyclable artificial marble is prepared from, by mass, 4%-30% of epoxy prepolymers, 2%-20% of imine curing agents, 0.05%-1% of catalysts, 50%-90% of inorganic filler and 0-20% of auxiliaries, the artificial marble is formed by hot-pressing and curing the raw materials. According to the method, an epoxy prepolymer, an imine curing agent and a catalyst composition are adopted as an adhesive, and the purpose of recycling the artificial marble is achieved by utilizing the function that an imine dynamic covalent bond can be recombined with matrix resin through a dynamic reversible exchange reaction under a certain condition. The artificial marble is simple in preparation process, low in shrinkage rate in the curing process, excellent in mechanical performance, heat resistance and corrosion resistance and capable of shielding ultraviolet rays, leftover materials and waste can be recycled, energy is saved, and the environment is protected.
本发明属于建筑装饰材料领域，具体公开了一种可循环回收利用的人造大理石及其制备方法，以质量百分含量计，包括如下原料：环氧预聚物4％～30％、亚胺固化剂2％～20％、催化剂0.05％～1％，无机填料50％～90％和0～20％的助剂，所述人造大理石由上述原料热压固化而成。该方法采用环氧预聚物、亚胺固化剂和催化剂组合物为粘接剂，利用亚胺动态共价键在一定条件下能够通过动态可逆交换反应与基体树脂重新结合的功能实现人造大理石循环回收利用的目的。该人造大理石制备工艺简单、固化过程收缩率较低，具有优良的机械、耐热、耐腐蚀性能，可屏蔽紫外线，边角料和废弃物可循环回收再利用，节约能源、保护环境。
