The invention discloses a preparation method of a graphene anti-cutting coating, which comprises the following steps: (1) dissolving graphene oxide in a waterborne polyurethane emulsion under a certain condition to obtain a component A; (2) grafting anti-cutting particles and chiral molecules under certain conditions to obtain a component B; and (3) uniformly mixing the component A and the component B under a certain condition, and adding an auxiliary agent to obtain the coating. The prepared graphene anti-cutting coating has good anti-cutting performance and also has an excellent heat preservation function and an excellent far infrared heating function, meanwhile, the preparation method is simple, the effect is obvious, and the graphene anti-cutting coating can be widely applied to the fields of textiles, home textiles and the like. 本发明公开了一种石墨烯抗切割涂料的制备方法，包括如下步骤：(1)将氧化石墨烯在一定条件下溶于水性聚氨酯乳液中，得到A组分；(2)在一定条件下将抗切割粒子与手性分子接枝，得到B组分；(3)将A、B组分在一定条件下混合均匀，并添加助剂，得到涂料。本发明制备的石墨烯抗切割涂料具有良好的抗切割性能，并且还具有优异的保暖功能和远红外发热功能，同时本发明的制备方法简
