Modified formula of conductive master batch

Abstract

The invention discloses a modified formula of conductive master batch. The conductive master batch is obtained by uniformly mixing components, adding the mixed components to a double screw granulator and granulating the mixed components, and the components comprise, by weight, 25-30% of carbon black, 30-45% of polypropylene, 1-5 % of glass fibers, 1-2% of nanometer iron oxide, 1-2% of nanometer zirconium oxide, 0.5-1% of cocamamide, 1-5% of terpene resin, 5-10% of methylimidazole, 1-5% of naphthenic oil, 1-5% of polyoxymethylene, 1-5% of diatomaceous earth, 0.1-0.5% of silver nano-powder, 1-3% of polyhedral oligomeric silsesquioxane epoxy resin, 1-5% of cross-linked carboxymethylcellulose, 5-10% of polyurethane acrylate, 1-3% of nanometer aluminum isopropoxide, 0.1-0.3% of 2-hydroxy-2-methyl-1-phenyl-1-acetone, 0.1-0.3% of a polymeric flowable agent, 0.1-0.3% of an antioxidant, and the balance of polyethylene. The formula of the conductive master batch is improved, and direct granulation is carried out by adopting the traditional screw granulator and a traditional granulation technology, so the process is simple, the reaction in the crosslinking reaction is full, the production cost is low, the content of the carbon black in the conductive master batch is high, and the conductive master batch has good electrical conductivity, good injection fluidity, good surface appearance quality, good toughness, good bending strength and good other physical properties.

[0002] Conductive masterbatch contains carbon black, the content of carbon black determines the conductivity, the more carbon black content, the better the conductivity, the granulation process of the transmission is to mix all the components of the conductive masterbatch evenly and put it into the screw granulator , direct granulation to obtain conductive masterbatch, but the physical properties such as injection fluidity, surface appearance quality, toughness, bending strength and other physical properties of conductive masterbatch obtained by direct granulation by transmission process will be greatly reduced

Therefore, it is necessary to adopt more advanced granulation equipment and use more advanced and complex granulation process to solve the problem of reduced physical properties such as injection fluidity, surface appearance quality, toughness and bending strength of conductive masterbatch

However, it needs to be divided into several process steps, and multiple screw extruders and screw granulators are required, the equipment cost is high, the power consumption is large, and the production cost is high, so it is necessary to improve
