Abstract

The invention discloses a dustproof, antibacterial and anti-virus coating which comprises the following components in parts by weight: 90-98 parts of organic silicon resin; 2 to 10 parts of fluorosilane resin; 0.1-0.5 part of nano inorganic oxide with the particle size of 10-200 nm; 0.1-0.5 part of polymer microspheres with the diameter of 0.1-10 [mu] m; and 0.1-0.5% of an antibacterial agent. The coating not only has excellent dustproof, antibacterial and anti-virus performance, but also has good anti-static capacity and low surface capacity. The invention also discloses a preparation method of the coating. The coating is mainly applied to various electronic and electrical equipment, other products with dustproof requirements and the like.

Description

technical field [0001] The invention relates to a dust-proof, anti-bacterial and anti-virus coating. In addition, the invention also relates to a preparation method of the coating and its application in heat dissipation equipment of electronic appliances. Background technique [0002] With the advent of the 5G era, the demand for 5G electronic equipment and terminals has greatly increased, and the demand and consumption of 5G equipment for electricity have greatly increased, and the heat generated has also increased rapidly. If the large amount of heat released cannot be dissipated in time, it will Greatly affect the efficiency and service life of electronic and electrical equipment. [0003] At present, there are a large number of heat dissipation devices in various electronic devices, such as radiators in computer CPUs. As the use time increases, due to the existence of static electricity, air humidity and various pollutants in the air, a large amount of dust adheres to t...
