The invention discloses a scale inhibition composite material and a preparation method thereof, and the scale inhibition composite material comprises the following components by mass: 32-50% of a scale inhibitor; 50-68% of an inorganic carrier; or the scale inhibitor comprises the following components in percentage by mass: 30-50% of the scale inhibitor; 50-68% of an inorganic carrier; 0.6-2% of a binder; wherein the scale inhibitor is obtained by reacting an organic phosphine scale inhibitor or dispersing agent with carbonate or bicarbonate and calcium chloride. The scale inhibitor which is originally easily soluble in water is powerfully grafted on the surface of a carrier under the action of hydrogen bonds, so that the scale inhibitor is slightly soluble in water, a large number of active scale inhibition factors are generated, various scale forming factors cannot be combined, and the trace and efficient scale inhibition performance is achieved. Meanwhile, the selected raw materials are simple and easy to
