The invention relates to the technical field of building materials, provides anti-cracking concrete and a production process thereof, and solves the problems of failure of a concrete water reducer, high cracking risk and insufficient durability in a high-mud-content gravel environment. Comprising the following raw materials: an inorganic gelling system, fine aggregate, coarse aggregate, mixing water, a composite water reducer, modified magnesium-aluminum hydrotalcite, alkali-resistant reinforced fibers and potassium stearate. The composite water reducing agent is of a core-shell structure and comprises a shell layer and a core layer, the shell layer is a macromolecular network formed by copolymerization of acrylamide, acrylic acid and light-color N-acylamino acid phosphate, and the core layer is modified Bayer process white mud; the modified magnesium aluminum hydrotalcite is prepared from the following raw materials: magnesium chloride, aluminum sulfate, potassium hydroxide, nano SiO2, gamma-aminopropyltriethoxysilane, isopropanol and ethylene glycol; the alkali-resistant reinforced fiber is a carbon nano tube with an organic silicon coating on the surface.

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.
