Abstract

The invention discloses a fireproof and explosion-proof box special for a battery, and relates to the technical field of fireproof and explosion-proof boxes, the fireproof and explosion-proof box comprises a box body and a box cover, and the box cover is arranged on the box body in an openable manner; the box body comprises a phase change heat preservation material layer, a bonding layer, an anti-explosion layer, a bonding layer, a fireproof material layer and an outer box body layer which are sequentially arranged from inside to outside. The special fire-proof and explosion-proof box for the battery can integrate heat preservation, fire prevention, explosion prevention, monitoring and early warning, and can prevent a series of corrosive and flammable gases or steam and the like caused by battery disintegration or explosion, continuous heat conduction reaction, fire combustion, high temperature and electrolyte leakage to cause greater danger and disasters; danger can be rapidly monitored, mobile isolation is facilitated, and time is won for rescue and maintenance. Meanwhile, when the structure of the battery explosion-proof box bears high temperature, serious structural deformation does not occur, the sealing performance is good, flames and toxic gas are not emitted, and the surface temperature of the box body structure is lower than the temperature which can be borne by a human body.

Description

technical field [0001] The invention relates to the technical field of fireproof and explosion-proof boxes, in particular to a special fireproof and explosion-proof box for batteries. Background technique [0002] Batteries are more and more common in people's daily life. Compared with other batteries, lithium batteries are light in weight and small in size. Many products on the market today, such as new energy vehicles, power tools, computers, consumer electronics and Communication products use lithium batteries as power. Fires caused by batteries are different from traditional fires, especially lithium-ion batteries, which are commonly used today. The fire starts quickly, spreads rapidly, can release a large amount of toxic smoke, and has the danger of explosive shock. Once a fire breaks out, a chain reaction is likely to occur, igniting the surrounding battery system, and a large amount of water is required for cooling when extinguishing, otherwise it is easy to re-ignit...
