Embodiment 1

[0020] A buffer layer of a safety helmet, including a first unit 301, a second unit 303, and a third unit 305; Setting: both the first unit 301 and the third unit 305 are filled with cushioning materials, the first unit 301 is uniformly provided with hollow spheres 302 ; the second unit 303 is uniformly provided with elastic members 304 .

[0021] Further, the elastic member 304 is a return spring. After the cap shell 100 bears the downward impact force, the return spring will generate an elastic force corresponding to the above-mentioned impact force upwards, so as to prevent the impact force from continuing to move towards the cap liner 200, and effectively alleviate the damage of the impact force to the human head.

[0022] A buffer material for preparing the buffer layer of the safety helmet, which is composed of the following raw materials in parts by weight: 100 parts of methyl vinyl silicone rubber, 60 parts of modified fumed silica, 6 parts of phenyl silicone oil, and ...

Embodiment 2

[0028] It consists of the following raw materials in parts by weight: 110 parts of methyl vinyl silicone rubber, 80 parts of modified fumed silica, 9 parts of phenyl silicone oil, 3 parts of fluorine release agent, 10 parts of quartz powder, polydimethylsiloxane 2 parts of oxane. Other implementations are the same as in Example 1.

Embodiment 3

[0030] It consists of the following raw materials in parts by weight: 105 parts of methyl vinyl silicone rubber, 70 parts of modified fumed silica, 8 parts of phenyl silicone oil, 2.5 parts of fluorine release agent, 6 parts of quartz powder, polydimethylsiloxane 1 part of oxane. Other implementations are the same as in Example 1.

Abstract

The invention discloses a buffer layer of a safety helmet. The buffer layer comprises a first unit, a second unit and a third unit; the first unit, the second unit and the third unit are sequentiallyarranged from a helmet shell to a helmet liner; the first unit and the third unit are both filled with a buffer material, and hollow spheres are uniformly arranged in the first unit; elastic pieces are uniformly arranged in the second unit; the buffer material is prepared from methyl vinyl silicone rubber, modified fumed silica, a fluorine-containing release agent, quartz powder and polydimethylsiloxane. Compared with the prior art, the buffer layer has the advantages that the modified fumed silica has higher ductility, dispersibility and tensile property than fumed silica, and thus the buffereffect of the buffer layer is well improved; the buffer layer obtained finally is good in buffer effect and high in resistance and elasticity, and the safety performance is greatly improved.

Description

technical field [0001] The invention relates to the field of safety helmets, in particular to a cushioning layer of a safety helmet and the cushioning material used therefor. 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. Consists of shell, lining, lower chin strap and rear hoop. The cap shell is hemispherical, firm, smooth and elastic, and the impact and puncture kinetic energy of the striking object is mainly borne by the cap shell. There is a certain space between the cap shell and the cap liner, which can buffer and disperse the instantaneous impact force, so as to avoid or reduce the direct injury to the head. Impact absorption performance, puncture resistance performance, lateral rigidity, electrical insulation and flame retardancy are the basic technical performance requirements for safety helm...
