This invention relates to a multi-substrate painting swirl stick and its preparation method. The multi-substrate painting swirl stick includes sodium hydroxide, stearic acid, myristic acid, potassium stearate, and nano-silica. In this invention, sodium hydroxide reacts with stearic acid to form sodium stearate, and sodium hydroxide reacts with myristic acid to form sodium myristate. Sodium stearate, sodium myristate, and potassium stearate together form a composite hydrogel soap-based system. Nano-silica acts as heterogeneous nucleation sites, guiding the formation of a microcrystalline network structure during the formation of the composite hydrogel soap-based system. During application, this microcrystalline network structure can achieve controllable interlayer slippage under shear force, thereby resulting in good adhesion, good color development on smooth material surfaces, minimal flaking, uniform color application, strong hiding power, and smooth painting.
