The invention relates to the technical field of refractory material binders. The invention discloses a modified binding agent for a low-carbon composite refractory material. The modified binding agent comprises the following raw materials in percentage by mass: 95-99% of a binding agent Carbores P and 1-5% of a catalyst. The catalyst is one of nano FeO, CoO or NiO, and the median diameter of the catalyst is 50 nm. The residual carbon rate of the binding agent Cabores P is 85%, and the softening point temperature is 235 DEG C. The invention relates to a preparation method of a modified binding agent for a low-carbon composite refractory material, which comprises the following steps: uniformly mixing the raw materials prepared according to the mass percentage, pressing into a sample under the condition of 100-170MPa, baking for 24 hours at the temperature of 200 DEG C, and carbonizing to obtain the modified binding agent with a carbon nanostructure generated in situ by Carbore P. The carbonization treatment temperature is 1300-1500 DEG C, heat preservation is conducted for 3 h, and the heating rate is 2 DEG C/min. The modified binding agent can generate a carbon nanostructure in situ after being subjected to high-temperature carbon burying treatment, so that the residual carbon rate and the graphitization degree of Carbores P are increased, and the oxidation resistance and the thermal shock resistance of the low-carbon composite refractory material are effectively improved.
