What process can make conductive plastic

Time: 2018-08-29 20:36 Author: admin Hits: Times
The stability and processability of structural conductive plastics are still the main problems in industrial production and practical applications. Most of the structural conductive polymers developed in the industry are unstable and easily decomposed during heating. Some are sensitive to oxygen and some are stored during storage Lost its original nature.
In addition, they are insoluble in water and currently cannot be well dispersed in organic solvents or viscous resins, so there is no fixed molding method. To solve this problem, polymer blends have been developed abroad to improve their stability And processability. Or it can be first prepared as a soluble polysulfide so that it can be processed into the pancreas in solution.
Or use copolymerization and grafting methods to introduce processable parts. In recent years, conductive polymers formed by thermoplastic processing methods have been developed, and breakthroughs have been made in processing and applications. It is expected that more varieties will appear before doping And will stabilize after doping.
The conductive plastic filled with conductive plastic is formed by dispersion and compounding. The conductive filler and alkaline resin are evenly mixed in the kneading machine, and then granulated to form the particles.
The formation process of metal fibers is conductive plastic, and short fibers are directly added to the base resin. The process is the same as conductive plastics. Metal fibers can also be added with conductive fillers at the same time. The use of metal short fibers is not limited. Metal fibers and gold fibers can be used for Wire drawing or melt spinning.
Bundle long gold fibers and cut into 5-15am pieces (master batches), mix or clamp with alkaline resin, and evenly disperse; long metal fibers of various materials can be used.
When combined with alkaline resins, low speed and low shear stress devices should be used. BMC method (prefabricated all-mold plastic first weaves long metal fibers into a mesh (roller or silk blanket) and then puts it into two layers of plastic material .
The effect of adding metal fibers on the performance of the base resin is less than the effect of adding conductive fillers on the performance of the base resin. It has no effect on processability, equipment damage and pollution, and does not affect the coloring of the product. At present, the resistance of metal fiber conductive plastic The rate can reach 10Q.cm ...
