However, the electromagnetic shielding coatings in the prior art often have relatively poor radiation protection effect, and are easy to absorb external infrared rays (the electromagnetic shielding coatings in the prior art seldom have a reflection or shielding effect on infrared rays and visible light), causing the temperature of the coating to rise. Further weaken the anti-radiation function of the coating, and it is easy to cause the coating to fall off

Abstract
The invention belongs to the field of materials, and discloses a radiation-proof and heat-insulating coating, which comprises the following components: resin, nanometer metal, carbon nanotube, carbon nanotube, filler, solvent and auxiliary agent. Due to the one-dimensional structure of carbon nanotubes, it has special electronic properties. The combined use of nano-metals and carbon nanotubes is beneficial to improve the electromagnetic shielding performance of the coating and play a role in radiation protection; the use of fillers and carbon nanotubes , it is beneficial for the coating to reflect infrared rays and visible light, and conduct heat in time, and has a good heat insulation effect for electronic products coated with the coating. The coating contains basalt fiber, which further enhances the electromagnetic shielding performance of the coating. The high-speed stirring in the preparation process of the coating is conducive to the uniform dispersion of nano metals and carbon nanotubes on the filler surface, improving the electromagnetic shielding performance and the effect of reflecting infrared rays and visible light.
Description
technical field [0001] The invention belongs to the field of materials, in particular to a coating for radiation protection and heat insulation. Background technique [0002] With the rapid development of the electronic industry and the popularization of electronic products, tens of thousands of electronic and electrical equipment emit electromagnetic waves of different frequencies when they are working. These electromagnetic waves will cause cross-interference to various electronic and electrical equipment, communication and transmission lines that are working nearby, which is extremely harmful. [0003] Electromagnetic shielding coating is a radiation-proof coating that can be sprayed on non-metallic substrates such as composite materials, engineering plastics, wood, and cement surfaces to prevent or reduce electromagnetic radiation (such as microwaves, visible light, ultraviolet light, etc.) hazards. However, the electromagnetic shielding coatings in the prior art often...
