Conductive coating with self-cleaning function and preparation method

Abstract

The invention discloses a conductive coating with a self-cleaning function and a preparation method. The conductive coating with the self-cleaning function comprises the following raw materials in percentages by mass: 6% of a conductive material, 15% of a polyaniline / metal quantum dot composite material, 77% of a hydrophobic modified nano material and 2% of auxiliaries; the conductive material contains potassium hexatitanate and / or potassium octatitanate and tin indium oxide; and the auxiliaries comprise a dispersing agent, a coupling agent and a wetting agent. The coating is good in conductivity and easy to clean.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a conductive coating with self-cleaning function and a preparation method thereof. Background technique [0002] The existing range hood casing is made of plastic materials. Since the surface of the plastic material is electrically insulating, it is difficult to eliminate it when there is static charge on the surface, resulting in a large amount of dust and stains adsorbed on the surface of the plastic material, which is difficult to clean. At the same time, due to these Ordinary plastic materials have high surface energy, are easy to absorb stains, and also make the surface difficult to clean, which brings a lot of troubles to users and cannot meet the needs of users for easy cleaning. [0003] For this reason, search research is carried out on the prior art. [0004] In the Chinese patent CN101748461A, a two-step electrochemical treatment of aluminum or aluminum alloy sheets ...

Problems solved by technology

The superamphiphobic surface prepared by this method has the advantage of being easy to clean, but it has the problem of insufficient bonding strength or the surface is easily damaged.

[0005] However, the Chinese patent CN1379128A proposes a chemical vapor deposition method to prepare an array structure film with super-amphiphobic properties, but the process is relatively harsh, the cost is high, and it is not easy for industrial production and application.
