Abstract

The invention discloses a high-efficiency energy-saving cured carbon felt, and a preparation method thereof. The high-efficiency energy-saving cured carbon felt is prepared from, by weight, 650 to 720parts of soft felt, 30 to 40 parts of a dilluent, 50 to 100 parts of a curing agent, 200 to 300 parts of a resin, and 25 to 35 parts of an inorganic filing material. The preparation method comprisesfollowing steps: 1, felt cutting; 2, rubber preparation; 3, rubber coating; 4, manufacturing and moulding; 5, high temperature oven drying; 6, machining; 7, coating; 8 high temperature calcining; and9, detection. The high-efficiency energy-saving cured carbon felt is low in thermal conductivity, excellent in thermal insulation performance, uniform in density, low in heat storage capacity, quick in degassing, low in outgassing amount in vacuum, possesses heat impact resistance; product pollution or hearth pollution is not caused; furnace body effective space is enlarged; installation and maintenance are convenient; thermal insulation requirements of various monocrystalline growth furnaces and polysilicon ingot furnaces are satisfied. The preparation method is simple, is suitable for largescale industrialized production, and is promising in application prospect.

Description

technical field [0001] The invention relates to a high-efficiency energy-saving curing carbon felt and a preparation method thereof. Background technique [0002] In recent years, my country's investment in polysilicon smelting and drawing monocrystalline silicon has continued to increase, and the furnace size of the smelting equipment invested has continued to increase. However, polysilicon smelting and drawing monocrystalline silicon are high-energy industries that consume a lot of electricity. , the thermal insulation effect in the smelting furnace will directly affect the power consumption of polysilicon smelting, so the thermal insulation blanket with excellent high-temperature thermal insulation effect can effectively reduce the heat in the furnace from diffusing to the furnace wall, reduce energy consumption, and save energy. , thereby saving smelting costs and increasing profits. [0003] At present, compared with graphitized soft felt, solidified carbon felt has many...
