Abstract

Two shielding carbon fiber lines that generate heat of leading mainly generates heat the group by conductive silicone sheath and carbon fiber and becomes, and the carbon fiber generates heat the line to comprise a plurality of carbon fibers and insulating layer, and the carbon fiber generates heat the line and is two, and inside the conductive silicone sheath was arranged in to the parallel each other, it set up a plurality of earth connections to generate heat at two carbon fibers between the line. The utility model discloses an it sets up the conductive silicone sheath to generate heat the line surface at the carbon fiber, utilize the good electric conductive property of conductive silicone to play sealedly and the electromagnetic shield effect, conductive silicone has outstanding high temperature resistance ability simultaneously, want tens times higher at the electric heating cable applied conductive silicone in the inside than the conductive plastic life -span, the conductive silicone cost is less than copper metallic shield material far away, can a large amount of metal resources have been saved for the country, the inside earth connection that sets up of this external sheath, had high temperature resistantly, safety and environmental protection, excellent features energy -efficient and with low costs.

Description

Two shielding carbon fiber heating lines of leading

Technical field

The utility model relates to technical field of electric wires and cables, is specifically related to a kind of two shielding carbon fiber heating line of leading.

Background technology

Heating cable is widely used in the heating on floor, road surface etc., because carbon fiber is a kind of fibrous carbon material, there is the features such as corrosion-resistant, anti-oxidant (metal easily oxidation causes partial breakdown), high stability, life-span long (generally can reach the steady operation time of 100000 hours under 300 degrees Celsius). Carbon fiber heating cable has obtained increasing application.

Electromagnetic radiation is the main inducing of cardiovascular disease, diabetes, cancer sudden change; Radiation easily damages human reproductive system, nervous system, immune system; Radiation is the risk factor of the pathologies such as pregnant woman miscarries, sterile, monster; Radiation directly affects children's growth, development of bone marrow, causes visual impairment, retinal detachment, liver hematopoiesis function to decline; Radiation can make sexual function decline, female incretion disorder, menstrual disorder.

Carbon fiber heating cable is in use because the civilian electricity of China is the alternating current of 50HZ, therefore, in the time using this heating cable, can produce the electromagnetic wave field that one-period changes, user can be for a long time in so a kind of electromagnetic wave field, human body is produced to many harmful effects, and the electromagnetic radiation that how to solve carbon fiber heating cable becomes the technical problem of being badly in need of solution. Some producer solves electromagnetic radiation at the inner conductive plastics that adopts of carbon fiber as screen layer at present, but conductive plastics exists following problem: heat resistance is bad, easily aging at higher temperature; Oxygen atom in stability shortcoming electroconductive polymer is extremely unsettled to water; It is poisonous as AsF5, I2, Br2 etc. mostly adulterant is; Conjugated structure in difficult forming conducting polymer main chain makes strand stiff, does not insolublely melt, thereby brings difficulty to the processing that is freely shaped; Less economical its cost ratio metal and common plastics are high, are difficult to practical.

Utility model content

The utility model provides a kind of two shielding carbon fiber heating line of leading, to solve the problem of the carbon fiber heating cable electromagnetic radiation that prior art exists.

The utility model solves the technical scheme that its technical problem adopts:

A kind of two shielding carbon fiber heating line of leading, mainly formed by electric silica gel sheath and carbon fiber heating line, carbon fiber heating line is made up of some carbon fibers and insulating barrier, carbon fiber heating line is two, the electric silica gel sheath inside that is placed in parallel to each other arranges some earth connections between two carbon fiber heating lines.

Electric silica gel is by nickel coated copper powder, the conductive particles such as silver powder are evenly distributed in silica gel, make conductive particle contact by pressure, reach good electric conductivity, a kind of extruding continuously or the silicon rubber of compression molding of special electrically conductive particles that be mixed with, military and commercially have an application. Its Main Function is sealing and electromagnetic shielding. Product can mold pressing or extrusion molding, has on chip or other die-cut shapes is available. Shielding properties is up to 120dB (10GHz). Electric silica gel has good electromagnetic sealing and water vapor seal ability, and good electric conductivity (blanketing frequency reaches 40GHz) can be provided under certain pressure.

The utility model is by arranging electric silica gel sheath on carbon fiber heating line surface, utilize the good electric conductivity of electric silica gel to play sealing and electromagnetic shielding action, electric silica gel has outstanding resistance to elevated temperatures simultaneously, higher tens times than the conductive plastics life-span at heating cable the inside application electric silica gel, electric silica gel cost is well below copper metal shield materials, can be country and saved a large amount of metals resources, this external sheath inside arranges earth connection, has had high temperature resistant, safety and environmental protection, the good characteristic that energy-efficient and cost is low.
