Problems solved by technology

[0003] In the process of use, because the film formed by nitrile is relatively dense, it cannot play an anti-slip effect when it encounters liquids such as water or oil. However, nitrile latex has better oil resistance and cannot be chemically textured. In order to increase the surface friction, most gloves use salt spray as a surface treatment method, and this method not only destroys the latex, but also requires a lot of water to clean the salts such as sodium sulfate or sodium chloride. , causing waste of water resources and polluting the environment

Abstract

The invention relates to a preparing method for a butyronitrile-particle anti-sliding glove. The preparing method includes the steps that S1, first soaking gum with the first viscosity and second soaking gum with the second viscosity are provided, wherein the first soaking gum and the second soaking gum are obtained through hbutadiene-acrylonitrile latex by adjusting the viscosity, and the first viscosity is larger than the second viscosity; S2, a glove blank sleeves a hand mold, and the product is soaked into the first soaking gum in the step S1; S3, particles are evenly sprayed on the glovesoaked in the step S2, and then pre-drying is carried out; S4, the glove obtained in the step S3 is soaked into the second soaking gum, and the soaked glove is obtained after soaking; S5, the soaked glove obtained in the step S4 is heated and vulcanized, and the butyronitrile-particle anti-sliding glove is obtained. According to the preparing method for the butyronitrile-particle anti-sliding glove, particles outside the glove are increased, coating is carried out after particles, the original wear resistance and oil resistance of a product are guaranteed, the friction force of the surface ofthe glove is improved, the glove also has the anti-sliding effect after meeting liquid such as water or oil, and the operability is improved.

Description

technical field [0001] The invention relates to a preparation method of nitrile particle anti-slip gloves, which belongs to the field of labor protection products preparation. Background technique [0002] Gloves are used as a kind of protection to protect the hands. According to different working environments, the performance of the selected gloves is also different. Among them, cotton gloves and chemical fiber gloves are used as the inner liner, and one or two layers of nitrile latex are impregnated on the outside to form a protective layer on the surface of the gloves, so that the gloves have the functions of wear resistance, oil resistance, and anti-skid. [0003] In the process of use, because the film formed by nitrile is relatively dense, it cannot play an anti-slip effect when it encounters liquids such as water or oil. However, nitrile latex has better oil resistance and cannot be chemically textured. In order to increase the surface friction, most gloves use salt ...
