Embodiment 1

[0031] like image 3 As shown, a composite protective layer includes: a metal inner layer 5, a first polyurea layer 6, a hybrid fiber layer 7 and a second polyurea layer 8, which are sequentially arranged from the inside to the outside. Wherein, the hybrid fiber layer 7 is formed by alternately setting glass fiber layers and carbon fiber layers. The glass fiber layer is composed of several glass fibers arranged in the horizontal direction, and the carbon fiber layer is composed of several carbon fibers that are at a certain angle with the horizontal direction. The angle between the carbon fibers in the carbon fiber layer and the glass fibers arranged in the horizontal direction is an acute angle or an obtuse angle. For example, the glass fiber can be set horizontally, and the carbon fiber can be set at an angle of 45° or 135° with the glass fiber.

Embodiment 2

[0036] like figure 1 and 4 As shown, this embodiment provides an anti-explosion container, including a container body 1 formed of the composite protective layer provided in Embodiment 1, one end of the container body 1 is a sealed end, and the other end of the container body 1 is an opening The open end of the container body 1 is provided with a container flange 11 integrally formed with the metal inner layer 5 and provided with an annular clamping groove 12; the container flange 11 is provided with a composite energy-absorbing end cover 3, which is formed on the annular clamping groove 12. The opening and closing mechanism of the clamp 10 for opening or locking the composite energy-absorbing end cover 3 is arranged in the groove 12 .

[0037] like Image 6 As shown, wherein, the composite energy-absorbing end cap 3 includes a cover plate 16 and an encapsulation 19 disposed under the cover plate 16, and a sealing-energy-absorbing module is arranged in the encapsulation 19. ...

Abstract

The invention discloses a composite protective layer, which belongs to the technical field of anti-explosion containers. The composite protective layer includes: a metal inner layer, a first polyurea layer, a hybrid fiber layer and a second polyurea layer which are arranged in sequence from the inside to the outside. The technical scheme of the present invention is to introduce a polyurea elastomer into the anti-explosion main body of the fiber composite anti-explosion container to form a polyurea-fiber-metal composite protective shell, providing a light-weight, high-strength, simple structure, safe and reliable, sealing Portable composite material with good performance, the anti-explosion container made of this composite material can protect personnel and equipment in close range and in all directions, and can be used in trains, airplanes and other places with limited space and dense people.

Description

technical field [0001] The invention relates to the technical field of anti-explosion containers, and more particularly to a composite protective layer and an anti-explosion container. Background technique [0002] Anti-explosive containers can limit the scope of action of shock waves, detonation products and fragments generated by the explosion of explosives inside the container, and effectively protect the safety of personnel, equipment and the environment. It plays an important role in the field of safety and is a typical high-end explosion protection equipment. [0003] Metal anti-explosion containers are simple to manufacture and inexpensive, and are widely used. Composite anti-explosion containers have the characteristics of light weight and high strength, and have also been developed in recent years. The composite anti-explosion containers currently used are mostly filament wound composite materials. When carrying the same explosion equivalent, their weight is only ...
