Abstract

A fire-resistant thermal isolation insulation tube comprises an insulation layer, a thermal isolation packing layer, a low-expansion alloy shell and a fire-resistant protection material layer from interior to exterior in sequence. The thermal isolation packing layer is internally provided with a tube supporting frame. The insulation layer is made of a carbon fiber insulation material. The thermal isolation packing layer is made of kieselguhr. The low-expansion alloy shell is made of ferronickel materials. The fire-resistant protection material layer is made of silicon carbide. The fire-resistant thermal isolation insulation tube has the advantages that high-temperature open fire can be effectively prevented from damaging a tube stock and circuits in a cavity of the tube stock, tube stock deformation and fracture caused by the high temperature are prevented, and more serious damage caused by the short circuit of the inner circuits is prevented.

Description

technical field [0001] The invention relates to the field of fire-resistant protective materials, in particular to a fire-resistant and heat-insulating insulating pipe. Background technique [0002] With the increasing number of engineering constructions today, the demand for engineering fire protection is also increasing. In the event of a fire, intact electronic circuits can not only help fire rescue, but also prevent fires caused by short circuits caused by high-temperature open flames. Second fire, causing greater damage and loss. [0003] Existing fire-resistant circuit pipelines have low fire-resistance performance, and will be deformed due to thermal expansion under long-term burning, resulting in a decrease in fire-resistance performance and damage to the circuit. At the same time, due to the possibility of internal short circuit at high temperature, there is an unknown fire hazard to the outside world. Contents of the invention [0004] The invention aims to sol...
