Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a sensor lead wire insulating layer material. Background technique [0002] At present, most sensor leads are copper wires or other conductive metals covered with a layer of insulating material. Ordinary leads often generate a lot of friction during installation or construction, resulting in damage to the insulation layer, exposing the copper core, and causing safety hazards. , If it cannot be found and replaced in time, it is prone to leakage, fire or even fire. [0003] Chinese patent 201310405047.1 discloses a material formulation of a cable insulation layer with good insulation performance. The formulation includes reclaimed rubber, gas-mixed carbon black, light calcium carbonate, adhesive, butadiene rubber and flame retardant, each component The mass percentages are as follows: reclaimed rubber 10% to 15%, gas-mixed carbon black 2% to 6%, light calcium carbonate 15% to 25%,...
