Abstract

The invention relates to a hydrophilic coating with a high antistatic property and a preparation method thereof. The hydrophilic coating with the high antistatic property is prepared from the following components in parts by weight: 0.3-1.8 parts of conductive filler, 0.5-1.5 parts of conductive auxiliary, 25-50 parts of silicate solution, 10-35 parts of nano sol, 13.4-42 parts of solvent and 0.5-1 part of auxiliary. In preparation, the components are mixed according to a proportion. According to thehydrophilic coating with the high antistatic property and the preparation method thereof provided by the invention, the partial discharge and the dust viscosity caused by poor electrical conductivity of a base material are solved; the hydrophilic coating has the advantages that the hydrophilic property is good, the using experience of a user is improved, the cleaning difficulty is reduced, and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a hydrophilic coating with high antistatic performance. Background technique [0002] In 2000, Professor Shirakawa of Japan and Professor MacDiarmid of the United States discovered that polyacetylene has high conductivity, which broke people's traditional thinking, that is, the concept that high molecular polymers are insulating, and made conductive polymers become the focus of many scientific research work. The focus of the researchers' research has aroused extensive attention. Conductive polymers are formed by chemical or electrochemical doping of polymers with conjugated π bonds, and a class of polymer materials whose conductivity extends from insulators to conductors. [0003] Traditional plastic parts are insulating materials, and home appliances are mostly made of plastic materials. Plastic materials have always been the main raw materials used in home appliances due to ...
