The invention discloses a polyurethane waterproofing agent containing long-chain alkane and a preparation method thereof, and when the polyurethane waterproofing agent is prepared, polydimethylsiloxane with high silicon-oxygen bond energy, low surface energy and molecular chain elasticity and glyceryl monostearate containing long-chain hydrophobic alkane groups are introduced into a polyurethane system; comprising the following steps: polymerizing TDI (toluene diisocynate), TMP (trimethylolpropane) and polydimethylsiloxane to obtain a prepolymer 1; the prepolymer 1 is subjected to a polymerization reaction with N-MDEA, diacetylmonoxime and GMS in the presence of a catalyst DBTDL, and a prepolymer 2 is obtained; acidifying the prepolymer 2 into salt to obtain a prepolymer 3; uniformly mixing the prepolymer 3 and deionized water, and carrying out self-emulsification through an emulsifying machine or by applying an instantaneous nano precipitation technology FNP to obtain a polyurethane emulsion containing long-chain alkane, so as to prepare the polyurethane waterproof agent containing long-chain alkane. The polyurethane waterproof agent prepared by using the FNP has smaller particle size, better stability and good waterproofness, can be continuously emulsified, and has a relatively great application prospect in the field of fabrics.

The invention provides a cinnamon, turmeric and coffee composition for inhibiting appetite as well as a preparation process and application thereof. The composition is prepared from the following raw materials in parts by weight: 98.5 to 99.25 parts of freeze-dried black coffee, 0.5 to 1 part of cinnamon extract and 0.25 to 0.5 part of turmeric. The preparation process comprises the following steps: S1, preparing freeze-dried black coffee: S1-1, selecting; s1-2, performing baking; s1-3, performing crushing; s1-4, extraction is carried out; s1-5, performing concentration; s1-6, carrying out freeze drying; s2, preparing the cortex cinnamomi extract: S2-1, crushing; s2-2, extraction is carried out; s2-3, drying is carried out; s3, mixing, and the prepared cinnamon and turmeric coffee composition achieves the weight-losing effects of inhibiting appetite and promoting fat loss and can be applied to weight-losing products.

The invention discloses methomyl soluble powder and a preparation method and application thereof, and relates to the field of pesticides, the methomyl soluble powder comprises the following raw materials by weight: 50-95% of methomyl, 0.1-10% of a wetting dispersant, 0.1-10% of an anti-caking agent, and 0-49.8% of a filler. According to the soluble powder disclosed by the invention, the problem that methomyl soluble powder is easy to cake is reduced or eliminated by selecting auxiliaries, long-time storage is facilitated, sub-packaging is easy, the problem of dissolution stability is solved, and the methomyl soluble powder is more uniform and more stable in the use process.

This invention relates to an anti-sulfur poisoning catalyst, its preparation method, and its application. The preparation method includes: mixing a platinum source, a vanadium source, oxalic acid, aluminum oxide, and a solvent under stirring conditions to obtain a suspension; the suspension is then dried and sintered to obtain the anti-sulfur poisoning catalyst. The anti-sulfur poisoning catalyst prepared by this invention exhibits excellent anti-sulfur performance and high activity. Through the sacrificial action of vanadium, it adsorbs sulfur oxides, thereby protecting the platinum active sites. This invention employs an impregnation method, utilizing oxalic acid as a co-solubilizer for the vanadium source, resulting in a clean and low-cost production process with promising application prospects.

This invention relates to a one-step method for synthesizing flake-like Ba3(VO4)2. The method includes the following steps: mixing an alkali source, a vanadium source, a barium source, and water, and stirring the mixture. The alkali source accounts for 5-20 wt% of the water mass. After the stirring reaction, solid-liquid separation is performed to obtain flake-like Ba3(VO4)2 and a filtrate. The method provided by this invention eliminates the need for high-temperature calcination and precise pH control, enabling the direct and efficient synthesis of highly crystalline and uniformly morphologically uniform flake-like Ba3(VO4)2 under mild conditions. This significantly reduces production costs and process complexity, and the production process is more economical and cleaner.
