Problems solved by technology

[0003] However, what follows is the problem of scratch resistance of the conductive coating coated on the surface of electronic products. If the reliability of the coating is insufficient, scratches often occur so that the conductive coating cracks, not only not Conducive to the maintenance of electrical conductivity, but also affect the appearance

Abstract

The invention relates to the technical field of functional coatings, in particular to an anti-scratch conductive coating. The thickness of the conductive coating is 80-100 micrometers, and the conductive coating comprises, by weight, 50-80 parts of matrix resin, 10-30 parts of curing agent, 10-15 parts of inorganic filler particles, 10-50 parts of conductive powder, 3-10 parts of additives and 10-30 parts of diluent; the inorganic filler particles form protrusions on the conductive coating, the height of the protrusions is 3-15 micrometers, and the coverage rate of the protrusions on the surface of the conductive coating is 30-60%. The anti-scratch conductive coating contains the inorganic filler particles, protrusion structures are formed on the surface of the conductive coating, accordingly the anti-scratch performance of the conductive coating is effectively improved, the damage to the conductive coating caused by the applied force of the external environment is avoided, and the service life of the conductive coating is prolonged.

Description

technical field [0001] The invention relates to the technical field of functional coatings, in particular to a conductive coating with scratch resistance. Background technique [0002] Conductive coatings generally contain matrix resins, solvents and conductive substances, which can form a conductive coating on a substrate (such as a high-resistivity polymer material). The conductive substance in the coating can conduct current, eliminate the accumulation of static charges, and shield Electromagnetic radiation. When the surface of electronic products is coated with conductive paint, on the one hand, it can prevent the interference of electromagnetic wave radiation in the environment on the signals of electronic products, so that the signals of electronic products are fidelity and stable; on the other hand, it can prevent electronic products from polluting the environment by electromagnetic wave radiation. Keep the signal of electronic products confidential. The conductive ...
