The present invention proposes an alumina slurry with high solid content and low viscosity and a preparation method thereof, which relates to the field of alumina fiber composite materials, and the preparation steps include: preparing a lanthanum phosphate precursor solution; adding high-purity nano-alumina powder to the lanthanum phosphate precursor solution to obtain an alumina slurry with lanthanum phosphate; mixing the alumina slurry with lanthanum phosphate in a high-speed disperser, and then heating it to obtain a mixed system; after the mixed system is gelled, high-temperature sintering is performed to obtain a solid; deionized water is added to the solid and ball-milled to obtain an alumina slurry with high solid content and low viscosity. The present invention can solve the problem of low impregnation efficiency in the preparation process of alumina-based composite materials.

The application discloses a special dust-settling agent under a tunnel construction environment and a preparation method thereof. The application relates to the field of dust-settling agent preparation under a tunnel construction environment, and solves the problems of high preparation cost, difficulty in large-scale production and limited dust-settling performance of the existing dust-settling agent preparation method. In the application, polyvinyl alcohol, guar gum and itaconic acid are subjected to graft copolymerization reaction under nitrogen protection at 60 DEG C-70 DEG C, N,N'-methylene bisacrylamide crosslinking agent is added to form a chemical crosslinking network, and then the chemical crosslinking network is compounded with a surfactant to obtain the dust-settling agent. The dust-settling agent does not need low-temperature freezing and thawing treatment, can significantly reduce equipment energy consumption and production cost, is convenient for industrialized production, has good film-forming property, moderate viscosity and long water-retention duration, and can efficiently inhibit diffusion of dust generated in tunnel construction.

The present invention discloses a high-efficiency heat storage phase-change composite material and a preparation method thereof. A mechanical ball milling method is used to compound high latent heat lithium-based fluoride salt, nitrate and chloride salt in a specific proportion to achieve the design of low-temperature high latent heat eutectic molten salt. Graphene is functionally modified by a strong oxidant to increase the spacing between graphene sheets and improve the agglomeration effect of graphene in molten salt. In addition, the dispersion uniformity of graphene in the composite material is further improved by strong ultrasonic dispersion, forming a low thermal resistance heat conduction path, thereby improving the heat transfer performance of the composite material. The raw materials of the entire phase change material are widely available and the synthesis method is simple, which improves the problem that the current phase change material cannot take into account both high heat storage and high thermal conductivity, realizes the rapid charging and discharging function of the phase change material, and is conducive to the large-scale promotion of heat storage applications.
