Abstract
This invention discloses an electrothermal felt plate of activated charcoal fiber and its manufacturing method containing electrothermal conversion material, electrodes, power source contacts, insulating layer. The character of the electrothermal conversion material is the activated charcoal fiber felt adhered by the electrode and the power source contacts. The said insulating layer has two layers with the first one on the two sides of the activated charcoal fiber belt. An energy storage layer and an outer decorated layer are at the two sides of the first insulating layer and the second insulating layer is adhered to a said surface of the second insulating layer with strong insulation.
Description
The invention belongs to activated carbon fiber electric heating conversion field, especially a kind of electrothermal felt plate of active carbon fibres and manufacture method thereof.
At present, prior art adopts extrusion coating paper as the electric heating transition material, extrusion coating paper only contains the carbon fiber content of 4-5%, so electric heating conversion efficiency is low, and mechanical strength is low, when surface temperature surpasses 60 ℃, difficulty is installed and used in clot easily, in addition because insulating barrier is a single layer designs, therefore insulation effect is poor, has that heat-energy losses is big, the high deficiency of cost.
The purpose of this invention is to provide a kind of anti-steady height, mechanical strength height, low production cost, electrothermal felt plate of active carbon fibres and manufacture method thereof that heat-energy losses is little.
Technical scheme of the present invention is: electrothermal felt plate of active carbon fibres, comprise electric heating transition material, electrode, power supply contact, insulating barrier, it is characterized in that described electric heating transition material is an active carbon fiber felt, electrode and power supply contact are attached on the active carbon fiber felt, described insulating barrier has two-layer, the ground floor insulating barrier is attached to the active carbon fiber felt both sides, both sides at the ground floor insulating barrier are attached with accumulation of energy layer and outer decorative layer respectively, be attached with second layer insulating barrier in the both sides of accumulation of energy layer and outer decorative layer, on a side surface of second layer insulating barrier, be attached with heat insulation layer.
Described ground floor insulating barrier is inorganic prepreg, and second layer insulating barrier is polyester precoated film.
Described heat insulation layer is a reed straw pulp heat-insulating shield.
Described accumulation of energy layer is a metal foil paper.
Make the method for electrothermal felt plate of active carbon fibres, it is characterized in that active carbon fiber felt, electrode, first insulating barrier, outer decorative layer, accumulation of energy layer and second insulating layer material are carried out cutting, and electric heating felt, electrode, first insulating barrier, outer decorative layer and accumulation of energy layer, second insulating barrier stacked according to order from the inside to surface, carry out the hot pressing first time then, 160 ℃-180 ℃ of hot pressing temperatures, pressure is 250-400kg/cm
2, then, according to specification cutting heat-insulating shield, and at a spray epoxy class glue of heat-insulating shield, stack with for the first time hot-forming intermediate products then, carry out the hot pressing second time, the secondary hot pressing temperature is 80-100 ℃, pressure is 250-400kg/cm
2, form primary product through secondary hot pressing, at last at the power supply contact tining, form final products.
Hot pressing temperature is 170 ℃ for the first time, and pressure is 300kg/cm
2, hot pressing time is 2-5 hour.
Intermediate products through a hot pressing forms before carrying out secondary hot pressing, pass through 1-1.5 hour cooling time.
Hot pressing temperature is 90 ℃ for the second time, and pressure is 300kg/cm
2, hot pressing time is 1-2 hour.
The primary product of process secondary hot pressing will be through 0.5-1 hour cooling time before carrying out the power supply contact tining.
Activated carbon fiber to same specification resistivity is sticking, the power and the temperature that can determine electrothermal felt plate of active carbon fibres according to the series connection and the connected mode in parallel of its length and circuit.
Advantage of the present invention is: because the electric heating felt of electrothermal felt plate has adopted the activated carbon fiber powder, therefore improved electric conversion efficiency greatly, the heat efficiency is up to more than 99%; The electron density of electrothermal felt plate is very even in addition, and area of dissipation is big, and has increased insulating barrier and heat insulation layer, has therefore reduced the heat-energy losses in the practice highlightedly; Owing to adopt double insulating layer, therefore have the dielectric strength height in addition, reaching 6000V does not have the standard of hitting network, and peripheral insulating barrier also has the effect of watertight composition, and does not have any air, environmental pollution; For technology has been simplified in the warm installation of electricity, easy to use, reduced installation cost; Make that the electrothermal felt plate production technology is simple, device simple, operation easily, waste of raw materials be little, so manufacturing cost reduces greatly.
