Abstract

The invention discloses an inflaming retarding typed carbon fiber heating cable comprising a carbon fiber heating element. A protective sleeve is arranged around the heating element, an insulating layer is arranged around the protective sleeve, the insulating layer comprises an inner insulating layer and an outer insulating layer, a shielding layer is arranged around the outer insulating layer, a threading casing pipe is arranged around the shielding layer, a ground lead is arranged between the shielding layer and the threading casing pipe, and the materials of the threading casing pipe contain nano-grade inorganic flame retardant. The inflaming retarding typed carbon fiber heating cable is good in inflaming retarding performance, and oxygen indexes acquired from the combustion performance testing is greater than 40 which meets requirements of safe use. The inflaming retarding typed carbon fiber heating cable is high in electric heating transfer efficiency, the carbon fiber electric heating element is a kind of black body radiation material, electric heating transfer efficiency increases 30% compared with metal heating, and electrothermal efficiency is about 100%.

Description

Technical field [0001] The invention relates to a heating cable, in particular to a flame-retardant carbon fiber heating cable. Background technique [0002] In winter, homes or public shopping malls say that they are designed to use floor heating for heating, and the heating source is radiated from the underground to the indoor space to achieve the heating effect. Electric floor heating is to heat the ground by laying underground heating cables to generate heat. At present, heating cables have been widely used in industrial fields such as petroleum, chemical, thermal power plants and public fields such as fire pipelines. [0003] When heating cables are used outdoors in industrial fields, threading pipes are often used. At this time, the flame-retardant performance of the threading pipes is relatively high. Threading pipes can be divided into two types according to flame retardant: halogen-free flame-retardant and halogen-free flame-retardant. Although halogen-containing flame-r...
