Adopt the utility model has the advantages of:
1. the fire-proof and explosion-proof blanket mainly comprises an inner base cloth layer, a fiber felt layer, a metal foil layer, an explosion-proof layer and an outer base cloth layer. The inner base cloth layer is tightly attached to the cable, and the inner base cloth layer is made of non-combustible materials, so that flame can be extinguished and spread of flame can be inhibited at the first time of cable deflagration, and the fireproof and flame-retardant effects are achieved. The outer base cloth layer and the inner base cloth layer have the same fireproof and flame-retardant effects and serve as a first defense line when flames exist outside. The base cloth layer is provided with a special coating to enhance the tensile property and the wear resistance of the base cloth layer, and the fire-proof and explosion-proof blanket can be prevented from being scratched in the transportation or installation process. The fiber felt layer has very low heat conductivity coefficient and excellent heat insulation performance, and can greatly weaken high-temperature conduction; the material itself is also a non-combustible material and therefore also acts as a fire protection. The metal foil layer has high strength, can play certain explosion-proof effect when exploding, and the metal foil layer is dense and high temperature resistant, can protect cable joint when having flame externally. The explosion-proof layer has a special coating, has excellent tear strength and tensile strength, plays main explosion-proof effect when the cable deflagrates, can also bear and withstand the high-risk voltage that discharges when the cable deflagrates. In addition, the periphery of the edge of the inner base cloth layer and the periphery of the edge of the outer base cloth layer are connected in a sewing mode to form a containing area capable of being provided with the fiber felt layer, the metal foil layer and the explosion-proof layer.
2. The utility model is composed of multilayer materials, wherein, when the multilayer materials are wrapped and curled, the wrapping turns of the outer layer materials are less than that of the inner layer materials due to the different wrapping thicknesses of the different layer materials, thereby leading to difficult wrapping and even impossible wrapping; therefore, the outer diameters of the fiber felt layer, the metal foil layer and the explosion-proof layer are gradually increased to avoid the phenomenon, so that the protective effect is effectively achieved, and the installation by constructors is facilitated.
3. The utility model discloses all establish interior base cloth layer, fibre felt layer, metal foil layer, explosion-proof layer and outer base cloth layer into square structure. The cutting tool has the advantages of convenient cutting and high-efficiency mass production. When the cable is used, the cable can be wrapped uniformly, and the phenomenon that the number of wrapping layers of a certain part is small and the fireproof and explosion-proof performance of a finished product is influenced is avoided.
4. The utility model discloses a flexible material constitutes, compares in metal cable protection device or other hard material cable protection device, can use on the cable turn. Compared with a hard material, the thickness and the weight of the fireproof and explosion-proof blanket are more convenient to install and use in a narrow space.
