The invention relates to the technical field of elevator switch boxes, and discloses an elevator switch box with a fireproof function. The elevator switch box comprises an outer shell and an inner shell, wherein the interior of the outer shell is fixedly connected with a heat insulation flame retardant layer. According to the elevator switch box with the fireproof function, the outer shell and the inner shell are arranged, the outer shell and the inner shell are made of ceramic silicone rubber materials, the ceramic silicone rubber has the excellent characteristics of fire prevention, flame retardance, low smoke, non-toxicity and the like, residues after combustion are hard, the ceramic shells are not molten and do not drip in a fire disaster environment, and therefore flame retardance of the elevator switch box is better realized, and use is safer. The elevator switch box is provided with a heat-insulation flame-retardant layer and a fireproof coating, the heat-insulation flame-retardant layer has the advantages of being high in strength, resistant to oxidation, low in heat conductivity, small in heat capacity and the like, the fireproof coating protects the elevator switch box against direct contact with air, ignition of the elevator switch box is delayed, the combustion speed is reduced, and therefore the elevator switch box can be better subjected to heat insulation and flame retardance.

    本发明涉及电梯开关盒技术领域,且公开了一种具有防火功能的电梯开关盒,包括外壳和内壳,所述外壳的内部固定连接有隔热阻燃层。该具有防火功能的电梯开关盒,通过设置外壳和内壳,外壳和内壳为陶瓷化硅橡胶材料,陶瓷化硅橡胶具有极佳的防火、阻燃、低烟、无毒等特性,其燃烧后残余物为坚硬的陶瓷化壳体在火灾环境中不熔且不滴落,从而更好的对电梯开关盒进行阻燃,从而在使用时更加安全,通过设置隔热阻燃层和防火涂料,隔热阻燃层具有强度高、抗氧化、导热率低、热容小等特点,防火涂料保护电梯开关盒不直接与空气接触,延迟电梯开关盒着火和减少燃烧的速度,从而更好的对电梯开关盒进行隔热阻燃。
