Problems solved by technology

[0002] Nowadays, the power bank electronic products on the market do not have any protective structure, and the user is extremely unstable and easy to slip when holding it. At the same time, the power bank may slip out of the pocket accidentally
This will cause the charging treasure to hit the ground directly, causing cracks or broken screens at the corners, which will cause adverse effects on the use of the charging treasure.
[0003] At present, the most common anti-drop method for charging treasures is: put an ordinary silicone shell on the outside of the charging treasure, which has an obvious protective effect, but the poor thermal conductivity of the silicone shell will easily cause the internal temperature of the charging treasure to rise significantly, resulting in obstacles to use. solve

Abstract

The invention discloses a preparation method of a power bank rubber sheath with good thermal conductivity. The preparation method comprises the following steps: stirring fluorinated silicon rubber, butyl rubber, chlorosulfonated polyethylene, potassium titanate whiskers, graphene, mica powder, talcum powder, montmorillonite, acetyl tributyl citrate and epoxidized soybean oil, regulating the temperature, and carrying out vacuum standing to obtain a mixed material; and heating the mixed material, standing the mixed material, adding tert-butyl hydroperoxide, an accelerant TMTM and an anti-aging agent, carrying out mill run and primary vulcanization, and then, carrying out secondary vulcanization to obtain the power bank rubber sheath with good thermal conductivity. The rubber sheath providedby the invention is excellent in mechanical property, so that the damage caused by unexpected dropping of a power bank of a mobile phone is favorably avoided; and a great number of thermal conductinglayers are formed inside the rubber sheath, so that the power bank rubber sheath is extremely good in thermal radiation effect and thermal stability, the temperature inside the power bank can be effectively reduced, and the normal use of the power bank can be guaranteed.

technical field [0001] The invention relates to the technical field of power bank, in particular to a method for preparing a rubber sheath of power bank with good thermal conductivity. Background technique [0002] Since the power bank electronic products on the market today do not have any protective structure, the user is extremely unstable and easy to slip when holding it. At the same time, the power bank may slip out of the pocket accidentally. This will cause the power bank to hit the ground directly, causing cracks or broken screens at the corners, which will have a negative impact on the use of the power bank. [0003] At present, the most common anti-drop method for charging treasures is: put an ordinary silicone shell on the outside of the charging treasure, which has an obvious protective effect, but the poor thermal conductivity of the silicone shell will easily cause the internal temperature of the charging treasure to rise significantly, resulting in obstacles t...
