[0031] Beneficial effects of the present invention:

[0032] The invention discloses a cut-resistant glove and a preparation method thereof. The invention comprises the following steps: adding polyurethane emulsion, nitrile latex, modified nano zirconium oxide, a cross-linking agent, a surfactant and a thickener into a mixer and stirring and mixing the mixture to obtain a dipping material; bonding a skin-contacting comfort layer and a cut-resistant layer to form a glove blank; and dipping the glove blank into a coagulant, taking the glove blank out and dipping the dipping material, drying the glove blank, and curing the glove blank to form a wear-resistant dipping layer to obtain the cut-resistant glove. The cut-resistant glove comprises a skin-contacting comfort layer, a cut-resistant layer and a wear-resistant dipping layer from the inside to the outside, wherein the skin-contacting comfort layer can make the glove have excellent The cut-resistant layer can effectively improve the anti-cutting performance of the gloves, greatly enhance the anti-cutting ability of the gloves, prevent sharp objects from easily penetrating, and effectively protect the safety of the hands. The wear-resistant impregnated layer can effectively improve the sealing and wear resistance of the gloves, and improve the durability and stability of the gloves. The cut-resistant gloves prepared by this preparation method can not only effectively protect the safety of the hands, but also enable the gloves to maintain excellent fit and flexibility even during high-intensity operations, ensuring that the operator can successfully complete the task in a complex environment, and significantly improving work efficiency and safety.

[0033] In the process of preparing the cut-resistant gloves, a cut-resistant layer is first prepared. First, p-methoxybromobenzene and p-methoxyaniline are reacted, and the bromine atom on the p-methoxybromobenzene reacts with -NH2 and -NH- in sequence to form an intermediate containing three benzene rings and a methoxy group. Then, the methoxy group on the intermediate forms a hydroxyl group under the action of boron tribromide to obtain a hyperbranched monomer. Then, the hyperbranched monomer, bisphenol AF, and 2,6-dichlorobenzonitrile are used as polymerization monomers to form a polyarylethernitrile containing a large number of CF bonds and hyperbranching to obtain a performance coating resin. Then, the performance coating resin is dissolved and coated on a carbon fiber cloth to obtain a cut-resistant layer. The carbon fiber cloth is a high-strength, high-modulus fiber material that can greatly improve the cut and puncture resistance of the gloves. The performance coating resin is used to After coating, the cyano group on it has strong polarity, which makes the carbon fiber cloth and the performance coating resin have excellent bonding effect. The molecular structure of the performance coating resin contains a large number of benzene rings, which can give it excellent mechanical strength, and can further improve the anti-cutting and puncture performance of the carbon fiber cloth. The introduction of a large number of CF bonds can make the carbon fiber cloth resist the erosion of various corrosive substances, improve its chemical resistance, enable it to maintain high performance in harsh environments, improve the safety of the anti-cut gloves, and increase the bonding strength of the cut-resistant layer with the skin-friendly comfort layer and the wear-resistant impregnated layer, improve the integrity and stability of the cut-resistant layer, so that the carbon fiber cloth can more effectively disperse and transfer stress when subjected to external force, thereby significantly improving the anti-cutting performance of the anti-cut gloves.

[0034] In the process of preparing the anti-cutting gloves, a modified nano-zirconia is also prepared. First, hydroquinone and isocyanatepropyltriethoxysilane are reacted, and the hydroxyl group on the hydroquinone reacts with the isocyanate group on the isocyanatepropyltriethoxysilane to form a strong modifier containing a large number of siloxane groups. Then, the nano-zirconia powder is treated with the strong modifier. After the strong modifier is hydrolyzed, the siloxane on it is converted into silanol and grafted onto the particle surface of the nano-zirconia powder to obtain modified nano-zirconia. Zirconia is an inorganic material with high hardness, high wear resistance and high chemical stability. After being added to the wear-resistant dipping layer, it gives it an excellent wear-resistant enhancement effect. After the nano-zirconia powder is modified, the dispersibility of the nano-zirconia powder can be improved, and a large number of silanol groups are introduced so that it can be connected to other components of the dipping material in the form of chemical bonds, thereby improving the overall uniformity and wear resistance of the wear-resistant dipping layer, making the wear-resistant dipping layer not easily worn and damaged, protecting the integrity of the internal structure of the gloves, and further improving the safety and durability of the anti-cutting gloves.
