Problems solved by technology

Metal-based fillers have good electrical conductivity, but are expensive and easy to oxidize, which will lead to a decrease in the electrical conductivity of the coating film; carbon-based conductive fillers and inorganic salt fillers are relatively low in cost compared to metal-based fillers, but their electrical conductivity is relatively poor. The conductivity of the film cannot meet the requirement of a resistance of less than 10 ohms measured by a digital ohmmeter; metal oxide fillers also have a balance between conductive effect and price

Abstract

The invention relates to a functional coating and particularly relates to an electroconductive coating for a plastic substrate material. The electroconductive coating comprises a matrix resin, a curing agent, electroconductive powder, an auxiliary agent and a diluent. The electroconductive coating also comprises a foaming agent. The matrix resin has viscosity of 100-2000 cP. The electroconductive coating comprises, by weight, 50-80 parts of the matrix resin, 10-30 parts of the curing agent, 10-50 parts of the electroconductive powder, 3-10 parts of the auxiliary agent, 10-30 parts of the diluent and 15-20 parts of the foaming agent. The electroconductive coating contains the foaming agent, can produce a foam structure in molding, can improve electroconductive powder contact probability, can reduce a use amount of the electroconductive powder and can reduce the cost of the whole electroconductive coating. The electroconductive coating layer with the electroconductive coating has a foam structure, has good buffering effects to external stress, improves impact resistance and prevents damage to the electroconductive coating under external stress.

Description

technical field [0001] The invention relates to a functional coating, more specifically, a conductive coating for plastic substrates. Background technique [0002] Conductive coating is a special functional coating developed rapidly along with modern science and technology, and has been widely used in various military and civilian industrial fields such as electronics, electrical appliances, aviation, chemical industry, and printing. Conductive coatings usually refer to a functional coating that is coated on a non-metallic substrate to enable it to conduct current and eliminate the ability to accumulate static charges. With the widespread use of household appliances, mobile phones, etc., the coating of conductive coatings on their shells can prevent electromagnetic interference, radio frequency interference, radio noise interference, and corona interference. Some conductive coatings can also play an antistatic role, so conductive coatings are increasingly valued by people. ...
