Problems solved by technology

One is composed of a metal layer helmet body and a high-strength fiber fabric layer helmet body arranged in the metal layer helmet body. This safety helmet is heavy and too rigid, which not only restricts the wearer's mobility, but also seriously affects the ability to perform tasks. play of action
The other is composed of a plastic layer and a high-strength fiber fabric layer helmet body arranged in the plastic layer helmet body. The plastic layer helmet body and the high-strength fiber fabric layer helmet body of this safety helmet are not tightly bonded, and the plastic layer helmet body and the high-strength fiber fabric layer There will be certain gaps between the layers of the helmet body, and the existence of the gap will undoubtedly affect the safety performance of the helmet. At the same time, the thickness of the existing high-strength fiber fabric layer helmet body is relatively thick, making the anti-riot helmet very bulky and low in comfort.
[0004] In addition, the environmental protection, touch and material of the lining material are also very important indicators for safety helmets. The environmental protection performance and contact feeling of existing materials need to be strengthened

Abstract

The invention relates to the technical field of safety equipment manufacturing, and in particular relates to a safety protective crash helmet with resistance to cold, heat and impact The safety protective crash helmet with resistance to cold, heat and impact of the invention comprises an outer helmet body and an inner liner body, wherein the inner liner body is connected with the outer helmet body through a buffer bracket;the outer helmet body is prepared by mixing modified phenolic epoxy acrylic resin and a wire mesh with other added substances to perform injection molding pressing; the inner lining layer is formed by first weaving and forming a net by using a fiber composite material and modified carbon fiber, and then curing through an adhesive formed by the combination of modified ultrahigh molecular weight polyethylene and other additives. According to the safety protective crash helmet with resistance to cold, heat and impact, the strength of the helmet body is improved; the helmet has excellent high-pressure-resistant, water-proof, flame-retardant and radiation-proof effects; meanwhile, through the preparation of t he inner lining layer, the tensile strength and mechanical property of a wearing material are improved, and a certain antibacterial effect is also realized; the manufacturing cost is reduced; relatively high practical value and good application prospects are realized.

Description

technical field [0001] The invention relates to the technical field of safety equipment manufacturing, in particular to a cold and heat shock resistant safety protective cap. 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 that prevents 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 h...
