Abstract
The invention relates to the technical field of heating plates, in particular to a conductive carbon crystal powder heating plate. The production method includes: grinding and mixing, by weight, 100 parts of flame-retardant epoxy resin, 5-30 parts of conductive carbon crystal powder, 30-50 parts of acetone, 2-3 parts of dicyandiamide and 0.5 part of imidazole to obtain conductive adhesive, coating glass fiber cloth with the conductive adhesive, heating and drying to obtain a conductive heating sheet, slicing the conductive heating sheet into conducive heating power sheets, spreading fixed copper wires to two sides of each conductive heating power sheet to obtain conductive heating power lead sheets, and pressing and combining the conductive heating power lead sheets with reserved conductive copper wires, and high-temperature-resistant epoxy resin insulation boards on two sides to obtain a semi-finished integrated product, mounting a frame and a switch heat-insulating board to the semi-finished product, and connecting a switch to the product to obtain the finished conductive carbon crystal powder heating plate. The conductive carbon crystal powder heating plate is applicable to everyday life, industrial and medical aspects such as floor heating, wall heating and office heating, and is simple in process, high in quality, low in cost, and convenient to popularize.
Description
technical field [0001] The method for manufacturing a conductive carbon crystal powder heating plate of the present invention relates to the technical field of heating plates; in particular, it relates to the technical field of a manufacturing method for a conductive carbon crystal powder heating plate. Background technique [0002] Existing heating panels both at home and abroad mainly add carbon fiber into paper fibers to make mixed paper paddles, make carbon fiber electric heating paper with papermaking methods, and finally make electric heating panels through double-sided cladding of insulating plates. The method and current situation of the known technology have high production cost, inconvenient use, short service life, low heat resistance temperature (less than 100 ° C), overheating will burn and unsafe use, and cannot be made into high-power heating plate products. But the scope of use is limited and other deficiencies, defects and drawbacks. Based on the inventor's...
