Problems solved by technology

However, for example, the insulating rubber sleeves worn by the workers are soft and bend, and the workers will raise their hands and shake the sleeves, and even the workers will take off the insulating gloves in violation of regulations, which will lead to some accidents. The rubber is not resistant to aging. And long-term use is easy to age, the service life is short, and it cannot guarantee the safe use of work. It can be seen that the existing live working gloves do not meet the existing use requirements, so it is seen that suitable protective equipment will play a vital role in safety. important role

Abstract

The invention discloses a preparation method of an anti-puncture glove for hot-line working and belongs to the technical field of high polymer materials. The preparation method disclosed by the invention is simple, convenient and feasible, according to the preparation method disclosed by the invention, copolymerization modification is adopted to form a polyurethane and nitrile rubber interpenetrating polymer network; the anti-puncture glove for live working is comfortable and convenient to wear, durable in use, good in physical and mechanical properties, and suitable for being worn in live working of electric and electrical equipment to prevent hands from directly touching electrified bodies, electric shock is avoided, and a hand insulation protection effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a preparation method of anti-piercing live work gloves. Background technique [0002] The guarantee factors of safe production operations should not be artificially divided into subjective and objective, and treating them separately is also conducive to clearer division of tasks. When reflecting on some accidents, it is the greatest guarantee for safe production and operation to ensure that the protective facilities are watertight and impeccable, even to the extent that anyone who wants to intentionally cause an accident will fail. To achieve this goal, adequate technical support is needed. At present, in the field of gloves for live work, there is a kind of live work gloves in some developed countries, which not only have the function of preventing electric shock, but also have the function of preventing falling. Wearing such gloves can really make people ...
