Problems solved by technology

[0003] In order to protect the internal electronic components in the harsh environment, the current charger plug is generally covered with a rubber protective layer on the outside of the electronic components. Since the heat generated by the electronic components is emitted through the rubber protective layer, the protective layer It is not easy to dissipate heat, and the internal temperature is too high, which may easily cause damage to electronic components

Abstract

The invention discloses a rubber heat conduction protecting layer for a charger plug. The rubber heat conduction protecting layer is prepared from the following raw materials in parts by weight: 110 to 120 parts of main ingredients, 1 to 1.6 parts of 1,3-bis(tert-butylperoxyisopropyl) benzene, 0.5 to 1.2 parts of dicumyl peroxide, 0.1 to 0.8 part of vulcanization accelerator CZ, 0.4 to 1 part of vulcanization accelerator TMTD, 75 to 85 parts of filling reinforcing agent, 2 to 8 parts of C9 petroleum resin, 0.5 to 1.5 parts of hydroxyl silicone oil, 1 to 2 parts of microcrystalline wax, 1 to 2parts of epoxidized soybean oil, 1 to 2 parts of polyvinyl alcohol, 1 to 4 parts of melamine polyphosphate and 1 to 2 parts of antiager. A preparation method of a cellulose compound comprises the following process: mixing ethyecellulose, formamide and acetone and raising the temperature for stirring; adding the epoxidized soybean oil and a carbon nanotube for continuously stirring; filtering, washing and drying to obtain the cellulose compound. The rubber heat conduction protecting layer for the charger plug, disclosed by the invention, has excellent mechanical property; in addition, the rubber heat conduction protecting layer is internally provided with a large number of heat conduction channels, so that internal heat of the charger can be dissipated in time and heat dissipation performance is excellent.

Description

technical field [0001] The invention relates to the technical field of chargers, in particular to a rubber heat-conducting protective layer for a charger plug. Background technique [0002] A charger generally refers to a device that converts alternating current to low-voltage direct current. Chargers are widely used in various fields, especially in the field of life, they are widely used in mobile phones, cameras, cars, etc. The charger is a static converter device that uses power electronic semiconductor devices to convert alternating current with constant voltage and frequency into direct current. [0003] In order to protect the internal electronic components in the harsh environment, the current charger plug is generally covered with a rubber protective layer on the outside of the electronic components. Since the heat generated by the electronic components is emitted through the rubber protective layer, the protective layer It is not easy to dissipate heat, and the in...
