Preparation method and structure of electric safety helmet

Abstract

The invention discloses a preparation method and structure of an electric safety helmet. The method comprises the steps that a machining mode is adopted for conducting model processing on a foamed aluminum middle core body, a foamed aluminum safety helmet shell body is obtained, then drilled and used as a basic model, the surface of the foamed aluminum safety helmet is dried, and a composite material used for preparing a resin shell body is subjected to hot melting, so that the composite material has certain flowability, and then the surface of the foamed aluminum safety helmet shell body is evenly coated with composite material; meanwhile, vacuum absorption is conducted, it is guaranteed that resin is fitted to the foamed aluminum safety helmet shell body, the foamed aluminum safety helmet shell body is polished and ground after cooled and solidified, and preparation of the safety helmet structure is completed. According to the preparation method and structure of the electric safety helmet, a design technology that the foamed aluminum middle core body is compounded with the resin is adopted, the electric safety helmet is low in weight and high in strength and also has excellent anti-impact vibration reduction performance, and the life safety of on-site operation personnel is guaranteed to a greater extent.

Description

technical field [0001] The invention relates to a preparation method and structure of an electric safety helmet. Background technique [0002] The safety helmet is a shallow dome hat made of steel or similar materials worn to protect the top of the head, and it is a protective product to prevent impact objects from hurting the head. When the worker's head is impacted by falling objects, a qualified safety helmet can decompose the impact force to the entire area of ​​the skull in an instant through the cap shell and cap lining, and then use the elastic deformation and plasticity of the cushioning structure of each part to The deformation and allowable structural damage absorb most of the impact force, reducing the final impact force on the head of the personnel to below 4900N, thereby protecting the head of the operator. [0003] At present, the materials used in the manufacture of safety helmet shells in China mainly include ABS (combined with acrylonitrile, J-ene and propy...

Problems solved by technology

[0004] Compared with helmets made of other materials, FRP helmets generally have significant advantages such as high strength, good electrical properties, and good corrosion resistance, but they also have low elastic modulus, easy deformation, poor long-term temperature resistance, and low interlayer shear strength. and disadvantages of easy aging

Under the action of ultraviolet rays, wind, sand, rain and snow, chemical media, mechanical stress, etc., it is easy to cause performance degradation and even endanger the life safety of operators.
