Description

Technical Field

[0001] The utility model relates to the technical field of explosion venting panels for building materials, in particular to a five-layer composite explosion venting panel and an explosion venting system. Background Technique

[0002] An explosion venting panel is an important product for preventing fires and explosions. It uses high-efficiency fireproof materials and explosion-proof designs. It can automatically rupture when the internal pressure of the system exceeds a predetermined value, thereby releasing pressure and avoiding equipment damage or explosion. The explosion venting panel can quickly play a role in the event of a fire or explosion, protecting people's lives and property.

[0003] Explosion venting panel materials are mainly divided into two types: metal and non-metal. Metal explosion venting panels are usually made of metals such as stainless steel, copper, and aluminum, and have characteristics such as high pressure resistance, high hardness, and light weight. They can withstand large pressure impacts without deformation or damage in high-temperature and high-pressure environments. Metal explosion venting panels are suitable for occasions with corrosion resistance, high pressure, high temperature, and complex fluid media. Non-metal explosion venting panels are usually made of special fiber materials, ceramic materials, fluororesin, etc., and the surface is treated with a PTFE (polytetrafluoroethylene) material coating, having good temperature resistance, corrosion resistance, chemical resistance, etc. Non-metal explosion venting panels are widely used in media with chemicals and viscous substances.

[0004] The main uses of explosion venting panels include explosion-proof and pressure-relieving walls and explosion venting roofs. Its working principle is that when an explosion occurs indoors, the explosion pressure is tightly closed, and then the critical pressure is relieved through the explosion venting panel. At the same time, by blocking the mass of explosion fragments and the buffering force of the explosion characteristics, the probability of explosion shock waves and explosion fragments causing personal injury and property damage can be reduced. In addition, the explosion venting panel can also control and isolate the large fire caused by the explosion to prevent the surrounding buildings from being affected. The installation of this kind of panel is simple, and only needs to fix the panel on the wall.

[0005] In the prior art, as shown in Chinese Utility Model Patent CN106988459A, a common metal explosion vent panel generally includes a three-layer structure, namely fireproof and heat-insulating rock wool and metal plates arranged on both sides of the fireproof and heat-insulating rock wool. Generally, the three-layer structure of the metal explosion vent panel is made by an adhesive bonding method. First, the rock wool on the side of the metal explosion vent panel made by this manufacturing method is exposed. The exposure of the rock wool will affect the overall waterproof and sealing effects of the wall, and additional sealing strips are required for sealing during installation. Sealing with sealing strips has the following defects: the installation steps are cumbersome, the sealing strength is insufficient, it is easy to be damaged, and it is not beautiful enough. Secondly, due to installation or other reasons, the metal plates on both sides of the existing metal explosion vent panel will be deformed, resulting in poor flatness of the metal plate on the outdoor side, which affects the appearance. Finally, with the development of various industries, the performance requirements for metal explosion vent panels are getting higher and higher, including the strength, quality, pressure relief, fire resistance limit, sealing performance, fireproof and heat insulation, and heat insulation performance of the wall after installation. The existing metal explosion vent panels can no longer meet the existing process requirements. Summary of the Invention

[0006] The purpose of the present invention is to solve the technical problems existing in the prior art, and provides a sandwich composite explosion vent panel and an explosion vent system, which solve the problems of poor sealing and waterproof effects caused by the exposure of rock wool in the prior art and poor flatness affecting the appearance, and meet the performance requirements of the existing metal explosion vent panels.

The two open ends of the honeycomb core face the composite explosion-proof panel and the honeycomb back panel respectively. Preferably, the glue is a two-component polyurethane adhesive, making the bonding effect more stable.

[0012] A further solution of the present utility model is that the honeycomb core is an aluminum honeycomb core.

[0013] A further solution of the present utility model is that the fireproof and heat-insulating filling material can be selected from one of rock wool board, glass wool board, polyurethane, aerogel. Preferably, the fireproof and heat-insulating filling material is a rock wool board.

The aluminum plate is the best choice as it is light in weight.

[0015] A further solution of the present utility model is that a decorative material coating forming a pattern is sprayed on the composite explosion-proof panel and / or the composite explosion-proof back panel.

[0016] An explosion-proof system includes the above-mentioned sandwich composite explosion-proof board, and also includes mounting angle brackets and purlins.
