The invention relates to a synthetic method capable of improving wettability of a zeolite molecular sieve. The synthetic method comprises the following steps: carrying out grinding mixing on a template agent or seed crystal and a solid raw material silicon source, an alkali source and/or an aluminum source; putting the grinded mixture into a reaction kettle, and crystallizing for 24-44 hours at atemperature of 160-190 DEG C; taking out the crystallized solid product, and drying; and roasting the obtained molecular sieve to obtain a ZSM-5 molecular sieve material with required infiltration performance, wherein the roasting process is programmed heating, and the roasting conditions are that the temperature is 400-800 DEG C, the heating rate is 1-10 DEG C/min, and the roasting time is 1-24 hours. By controlling the roasting conditions, the target control of the wettability of the molecular sieve is realized, the adsorption and catalytic performance of the molecular sieve to a substrate can be changed, the contro
