Embodiment 1

[0029]Use 2-3 micron stainless steel powder. Add a small amount of silane coupling agent to stainless steel powder, add 25 ml of alcohol-soluble phenolic paint according to the volume fraction of 15%, and stir evenly after adding, that is, the volume ratio of stainless steel powder and alcohol-soluble phenolic paint is 15%, of which: silane coupling The volume ratio of solvent to alcohol-soluble phenolic varnish is 2%. Put into ball mill and carry out ball milling, and the rotating speed of ball milling is 100 rev / mins, and ball milling time is 1 hour. After ball milling, pour it into the paint tank of the air compressor spray gun, and spray the paint on the inner side of the mobile phone case with the spray gun. The thickness of the spray coating is about 100 microns. The coating was left to dry after 24 hours at room temperature. After the coating is dry, use No. 5 metallographic sandpaper to lightly polish the surface of the coating to make it smooth. In order to ensure ...

Embodiment 2

[0032] 7-10 micron stainless steel powder is used. Add a small amount of silane coupling agent to stainless steel powder, add 25 ml of alcohol-soluble phenolic paint according to the volume fraction of 40%, and stir evenly after adding, that is, the volume ratio of stainless steel powder and alcohol-soluble phenolic paint is 40%, of which: silane coupling The volume ratio of solvent to alcohol-soluble phenolic varnish is 2%. Put into ball mill and carry out ball milling, and the rotating speed of ball milling is 100 rev / mins, and ball milling time is 1 hour. After the ball milling, pour it into the paint tank of the air compressor spray gun, and spray the paint on the inside of the mobile phone case with the spray gun, and the thickness of the spray coating is about 50 microns. The coating was left to dry after 24 hours at room temperature. After the coating is dry, use No. 5 metallographic sandpaper to lightly polish the surface of the coating to make it smooth. The extern...

Embodiment 3

[0034] Use 2-3 micron stainless steel powder. Add a small amount of silane coupling agent to stainless steel powder, add 25 ml of alcohol-soluble phenolic paint according to the volume fraction of 15%, and stir evenly after adding, that is, the volume ratio of stainless steel powder and alcohol-soluble phenolic paint is 15%, of which: silane coupling The volume ratio of solvent to alcohol-soluble phenolic varnish is 2%. Put into ball mill and carry out ball milling, and the rotating speed of ball milling is 100 rev / mins, and ball milling time is 1 hour. After ball milling, pour it into the paint tank of the air compressor spray gun, and spray the paint on the inner side of the mobile phone case with the spray gun. The thickness of the spray is about 120 microns. The coating was left to dry after 24 hours at room temperature. After the coating is dry, use No. 5 metallographic sandpaper to lightly polish the surface of the coating to make it smooth. The external antenna is ma...

Abstract

The invention discloses a radiation resistant mobile phone shell with the signal enhancement function and a manufacturing method of the radiation resistant mobile phone shell with the signal enhancement function, and belongs to the field of electronic device materials and application. The radiation resistant mobile phone shell comprises a mobile phone protection shell body, the inner side of the mobile phone protection shell body is coated with a radiation resistant coating, stainless steel powder is used as main shielding components of the radiation resistant coating, the particle sizes of the stainless steel powder range from 1 micrometer to 10 micrometer, and alcohol solubility phenolic aldehyde paint is used as base materials of the radiation resistant coating. Two external antennas are machined on the mobile phone protection shell body and used for being connected with a signal antenna and a Wi-Fi antenna of a mobile phone respectively. By means of the radiation resistant mobile phone shell, more than 70% of electromagnetic radiation of the mobile phone can be restrained; with the method that the external antennas are arranged, attenuation, caused by the radiation resistant coating, of signals of the mobile phone can be reduced to 5% from 30% generated when no external antenna is arranged, harm of electromagnetic wave radiation of the mobile phone to the human body is accordingly and effectively restrained, and meanwhile the conversion quality and the network quality of the mobile phone are guaranteed.

Description

technical field [0001] The invention belongs to the field of electronic equipment materials and applications, and relates to a radiation-proof mobile phone protective case for suppressing mobile phone electromagnetic wave radiation and enhancing mobile phone signals. Background technique [0002] With the advancement of electronic technology and electronic equipment, it has brought about the advancement of technology and the improvement of people's quality of life.
