The application belongs to the technical field of demulsification dehydration, and discloses a preparation method of a demulsifier and application of the demulsifier in asphalt mixture. The preparation method of the demulsifier comprises the following steps: reacting acidified clay minerals with gamma-methacryloxypropyltrimethoxysilane to obtain modified clay minerals; reacting the modified clay minerals with triethylenetetramine to obtain polyamine-based clay minerals; and reacting the polyamine-based clay minerals with bromohexadecane to obtain the demulsifier. The demulsifier is a polyquaternary ammonium salt type cationic demulsifier. Through the positive charges of cations contained on the surface of the clay minerals and quaternary ammonium salts, the double electric layer structure of the surface of anionic emulsified asphalt is changed, the thickness of the double electric layer is compressed, the electrostatic repulsion between the emulsified asphalts is reduced, and the demulsification effect is good. When the asphalt mixture is prepared, the adhesion of asphalt particles to aggregates can be effectively promoted, the water in the asphalt mixture can be effectively discharged, and the solidification and molding of the asphalt mixture can be accelerated.

This invention discloses a soybean phospholipid-based nanoemulsion and its preparation method, belonging to the fields of molecular biology and biomedicine. This invention addresses the technical problem of refining the particle size and improving the stability of existing soybean phospholipid-based nanoemulsions for use in fine pharmaceuticals. A method for preparing a soybean phospholipid-based nanoemulsion includes the following steps: S1, modified glycerol phosphorylcholine and cholesterol are mixed in ethanol, then phosphatidylethanolamine and a composite stabilizer are added to form an oil phase; deionized water, glycerol, and polyether F68 are mixed to form an aqueous phase; S2, the oil phase is injected into the aqueous phase and homogenized at high speed to obtain a preliminary mixture; the pH of the preliminary mixture is adjusted to prepare a primary emulsion; the primary emulsion undergoes low-pressure homogenization followed by high-pressure homogenization to obtain a nanoemulsion; the nanoemulsion is filtered through a microporous membrane to obtain the soybean phospholipid-based nanoemulsion. The nanoemulsion prepared by this invention has the advantages of small particle size and good photothermal stability.

This invention discloses a creatine kinase detection kit that counteracts lipemia interference and its preparation method. The kit includes reagent R1 and reagent R2; reagent R1 includes: purified water, imidazole, MgAC, and EDTA Na. 2 Glucose, PC300, Na 2 SO 3 N-acetylcysteine, NADP, AMP, ADP, AP5A, HK, and surfactant; reagent R2 includes: pure water, Capso, creatine phosphate, PEG6000, and NaN. 3 The kit contains BSA and G6PDH. The surfactant is one or a combination of two of Triton 100 and Tween 80. Through the synergistic effect of PEG6000 and the two surfactants Triton 100 and Tween 80, the creatine kinase detection kit significantly improves its resistance to lipemia interference and enhances its detection accuracy. The kit is simple to prepare, has strong resistance to lipemia interference, simple components, and low preparation cost, making it highly promising for market application.
