Varnish containing nano calcium carbonate filler

The invention relates to the technical field of varnish, and discloses a varnish containing a nano calcium carbonate filler, the varnish is prepared by mixing epoxy resin as a main film forming substance and modified nano calcium carbonate, a polyphenylene sulfide modifier, a dispersant and other auxiliary materials, the advantages of nano calcium carbonate are efficiently exerted, the wear resistance of the epoxy resin varnish is enhanced, the hardness of the epoxy resin varnish can be improved by adding a polyphenylene sulfide modifier, and meanwhile, the epoxy resin varnish can show the super-hydrophobic property due to a large number of extremely-low silicon-oxygen bonds and tert-butyl structures; therefore, the prepared epoxy resin varnish can have a self-cleaning effect. 本发明涉及清漆技术领域，公开了一种含纳米碳酸钙填料的清漆，该清漆是以环氧树脂为主要成膜物质，辅以改性纳米碳酸钙、聚苯硫醚改性体、分散剂等辅料，经混合制得，其中改性纳米碳酸钙能够充当化学交联核心的作用，高效发挥纳米碳酸钙的优势，增强环氧树脂清漆的耐磨性，聚苯硫醚改性体的加入可以提高环氧树脂清漆的硬度，同时大量具有极低硅氧键和叔丁基结构能够使环氧树脂清漆表现出超疏水性质，从而使制得的环氧树脂清漆能够具有自清洁效果。
