Problems solved by technology

However, with the advancement of technology, electronic products have higher and higher requirements for the performance of conductive masterbatches, and the conductivity can reach 1×10 4 Conductive masterbatches within Ω cannot fully meet the needs of the industry. Moreover, the conductive masterbatch has poor dispersibility due to the large content of conductive carbon black, and the interface between carbon black and polymer materials is poor, resulting in poor performance. , therefore, it is urgent to study a conductive masterbatch with better performance

Abstract

The invention relates to macromolecule conductive master batches which comprise, by mass ratio, 50% to 90% of polymer coated carbon nanometer tubes and 10% to 70% of carrier resin. Plastic finished products obtained through the conductive master batches are low in production utilization cost, the pipe surface is smooth, dispersity is good, no air bubble is inside products, and the quality is stable; the conductivity property (surface and internal resistance) achieves 5000 omegas on the premise of not increasing the cost, so that products have excellent antistatic properties.

Description
