The present invention also provides a kind of manufacture method of ceramic fire resistant electric wire, and this manufacture method, for the manufacture of above-mentioned ceramic fire resistant electric wire, comprises the following steps:
First, glass fiber tape be impregnated in ceramic silicon rubber silicon liquid glue, and wherein ceramic silicon rubber silicon liquid glue is the ceramic silicon rubber silicon liquid glue that comprises that liquid silastic silicon rubber, silicon dioxide, silicone oil, platinum complex and/or platinum compounds, Vitrified powder, vulcanizing agent are mixed to form;
Then, with the wrapped ceramic silastic-layer that forms on described conductor of glass fiber tape after dipping, wherein, at least wrapped one deck of glass fiber tape;
Finally, on ceramic silastic-layer, extrude the insulating barrier of coated described ceramic silastic-layer.
Preferably, the wrapped formation on described conductor before ceramic silastic-layer of glass fiber tape after dipping, is first dried processing to the glass fiber tape after dipping ceramic silicon rubber liquid glue.
The present invention also provides the manufacture method of another kind of ceramic fire resistant electric wire, and this manufacture method, for the manufacture of above-mentioned ceramic fire resistant electric wire, comprises the following steps:
First, on described conductor, form glass layer with glass fiber tape is wrapped, wherein, at least wrapped one deck of glass fiber tape;
Then, wrapped rear glass fiber tape is flooded or smear ceramic silicon rubber silicon liquid glue formation ceramic silastic-layer, wherein ceramic silicon rubber silicon liquid glue is the ceramic silicon rubber silicon liquid glue that comprises that liquid silastic silicon rubber, silicon dioxide, silicone oil, platinum complex and/or platinum compounds, Vitrified powder, vulcanizing agent are mixed to form;
