The invention belongs to the technical field of carbon deposition, and particularly relates to a preparation method for simulating a carbon deposition layer in a laboratory. The method specifically comprises the following steps: step 1, firstly performing slicing and sand blasting process treatment on a matrix rod-like material to obtain a test piece, then cleaning and drying the test piece, weighing and recording as m0; 2, preparing raw materials of the carbon deposition paste according to a certain mass ratio, and uniformly mixing; step 3, carbon deposition firing: uniformly smearing the carbon deposition paste obtained in the step 2 and covering the two-thirds area of the surface of one side of the test piece; heating the test piece coated with the carbon deposition paste to 250 DEG C, keeping the temperature for 2 hours, and cooling along with the furnace; step 4, taking out the sample, brushing away unfirmly bonded carbon deposits on the surface, weighing and recording as m1; and 5, calculating the quali
