Abstract
본 발명은 자율제어형 고분자 발열전선의 발열체용 콤파운드 및 콤파운드 제조방법에 관한 것으로, 발열체 조성물은 종래의 조성물 이외에 0.2 내지 2㎛의 입자크기의 무기충전제를 카본블랙과 동일함량 또는 2이상 함유하며 콤파운드 제조방법은 반바리믹서, 트윈스크류 압출기, 부스니더등에서의 용융혼련전에 카본블랙, 무기충전제등의 파우더타입의 첨가제를 볼밀혼합기, 헨셀믹서등을 이용하여 1차 드라이블랜드한 후 이들 파우더 첨가제와 매트릭스수지를 다시 2차로 용융혼련하여 제조함으로써 자율제어형 고분자 발열전선의 가열노화에 따른 출력저하가 방지된다.The present invention relates to a compound and a method for producing a compound for heating elements of a self-regulating polymer heating wire, wherein the heating element composition contains an inorganic filler having a particle size of 0.2 to 2 μm in the same amount or two or more as carbon black in addition to the conventional composition. In the method, the powder-type additives such as carbon black and inorganic filler are firstly dry-blended with a ball mill mixer, Henschel mixer, etc. before melt kneading in a half-barrier mixer, twin screw extruder, booth kneader, etc. By melting and kneading again to second, the output decrease due to heating aging of the self-regulating polymer heating wire is prevented.
