Screening conductive coating/paint

Abstract

The invention relates to a shielding conducting coating paint,comprising the following components;metal powder 25-45%,sticker 5-25%, and thickener 1-12%,solvent 20-25%,regulator of PH value 0.5-2% and water 5-20%. The slice-shaped conducting powder is arranged averagely when the product is sprayed to be film,with high conductivity,cleanliness and degree of shielding. Its raw material being chosen and matched reasonably,makes the electric very small and outstanding shielding effect. The invention has rapid drying in low temperature,outstanding adhesive force, density of adhesiveness and wear resistance.

Description

Technical field:

[0001] The invention relates to a chemical electronic material, especially a shielding conductive material, which is applied in the field of electronic communication. Background technique:

[0002] Electromagnetic interference refers to the phenomenon that the normal function of electronic devices is disturbed or caused by harmful electromagnetic waves, hereinafter referred to as EMI. EMI can interfere with the normal function of almost all electronic appliances. This pair of electrostatic discharges also has a negative impact on electronic devices and is harmful to human health. It is a kind of electronic pollution for both products and humans.

[0003] Product performance and cost requirements often prevent EMI problems from being resolved in the selection of electronic components. Therefore, the product chassis (shell) and wires are shielded to meet various specifications of electromagnetic compatibility. One method that is used more and more is to spr...
