Application of conductive carbon black in masterbatch

By introducing nano-scale carbon black into the conductive masterbatch, it has a significant impact on the improvement of the performance of the masterbatch. Black conductive masterbatch is mainly composed of PE or special polymer material as carrier, conductive carbon black and conductive synergist. Adding a certain amount of black conductive masterbatch to PE or polymer materials can reduce the surface resistance of the polymer to 104-109, and has good compatibility with PE, PP, PS, PC, ABS, PA, etc. The electrostatic property does not change with the change of ambient humidity, does not migrate, and does not separate out. It is an ideal antistatic agent for polymer materials.

The decrease in resistivity is not linearly related to the amount of carbon black added. When a certain amount of carbon black is added, even if carbon black is added, the conductivity does not change significantly. The level of electrical conductivity is also related to the type of carbon black, particle size and distribution, aggregate shape or structure, and porosity. Increasing the specific surface area and porosity of carbon black while reducing the ash content in the carbon black can improve the electrical conductivity and reduce the added carbon black fraction.

The smaller the particle size of carbon black, the more favorable it is to form a chain conductive structure. Generally, the number of thin passes is less, and some processing aids and plasticizers are appropriately added to help reduce the resistivity. The mixing temperature is appropriately higher, and the effect of acetylene carbon black and other carbon blacks will be better. Graphite has a similar structure to carbon black and is also a conductive filler. The special material for black conductive film is mainly composed of LDPE, conductive carbon black, processing aids and other components.

The conductive film material made of the material has stable anti-static property, good electrical conductivity, high mechanical strength and good printability, and can be used for the packaging of static-sensitive products. Widely used in the electronics industry, aerospace, weapon industry and textile industry, such as electronic components (devices), electrical products, optoelectronic products, optoelectronic integrated products and packaging of dangerous products such as ammunition The above is the information sharing of conductive carbon black brought by Shanxi Shengdawei.
