The invention discloses an energy-saving and environment-friendly protecting material for a slab continuous casting mold, which comprises raw materials by weight percent: 2-5% of carbon black, 1-3% of carburant, 11-15% of fluorite, 1-4% of sodium fluoride, 1-3% of cryolite, 2-5% of manganese carbonate, 2-5% of barium carbonate, 10-12% of white alkali, 7-15% of grain slag, 2-7% of calcite, 40-50% of wollastonite and 1.5-2.5% of yellow dextrin. When being used, the protecting material can show good spreadability, heat preservation performance and melting performance in a crystallizer; heat transmission amount at the periphery in the crystallizer is stable and uniform, and high casting speed requirements can be met; and testing slag strip is small, non-uniformity of inflow is improved, and the protecting material has good lubricity so as to prevent caking steel leakage. No slag inclusion or caking slag phenomena exist on the surface of a casting blank, so that the surface quality of the casting blank is good.
