Description

technical field [0001] The invention relates to the technical field of graphene materials, in particular to a preparation method of modified graphene slurry, a preparation method of graphene UV curing glue and an application method of composite glass. Background technique [0002] Graphene is a two-dimensional crystalline material composed of closely packed carbon atoms. Because of its unique structure and excellent electrical, mechanical, optical, chemical and thermal properties, it has become a research hotspot for many people. [0003] UV light-curing coatings have the advantages of no volatile organic compounds (VOC), less environmental pollution, fast curing speed, energy saving, good performance of cured products, and suitable for high-speed automatic production. However, traditional coatings are volatile and slow to cure, which is not conducive to environmental protection. Graphene is directly added into coatings and UV curing systems. Due to the large specific surfa...
