Graphene premixed mortar with thin-layer plastering and masonry functions and preparation method of graphene premixed mortar

The invention discloses graphene premixed mortar with thin-layer plastering and masonry functions. The graphene premixed mortar is prepared from raw materials in parts by weight as follows: 100-300 parts of cement, 500-800 parts of manufactured sand, 50-150 parts of water, 0-150 parts of limestone powder, 5-20 parts of a polycarboxylate superplasticizer, 10-20 parts of polyacrylamide, 500-800 parts of graphene, 5-10 parts of Arabic gum and 10-20 parts of azadirachtin. Graphene oxide is used for replacing part of manufactured sand, the Arabic gum and the azadirachtin are used as bonding agents,the viscosity and workability of mortar are effectively adjusted, so that the produced premixed mortar can meet the requirements of construction units for masonry and plastering under the condition of consistent strength numbers and conform to various indexes of masonry and plastering in the aspect of performance indexes. Meanwhile, the consumption of raw materials of the thin-layer plastering mortar is greatly reduced,
