Embodiment 1

[0059] Preparation of Bituminous Compositions for Protecting Electronic Components 1

[0060] 72g of blown pitch was heated to 180°C, 8g of ethylenebisstearamide wax was added, and stirred for 1 hour while maintaining a temperature of 170°C. After the stirring was completed, 20 g of calcium carbonate (CaCO 3 ), and then stirred for 2 hours, thus preparing an asphalt composition for protecting electronic components.

Embodiment 2

[0062] Preparation of Bituminous Compositions for the Protection of Electronic Components 2

[0063] 81 g of blown pitch was heated to 170°C, 9g of ethylenebisstearamide wax was added, and stirred for 1 hour while maintaining a temperature of 170°C. After the stirring was completed, 10 g of calcium carbonate (CaCO 3 ), and then stirred for 2 hours, thus preparing a pitch composition for protecting electronic components.

Embodiment 3

[0065] Preparation of Bituminous Compositions for the Protection of Electronic Components 3

[0066] 63g of blown pitch was heated to 170°C, 7g of ethylenebisstearamide wax was added, and stirred for 1 hour while maintaining a temperature of 170°C. After the stirring was completed, 30 g of calcium carbonate (CaCO 3 ), and then stirred for 1 hour, thus preparing a pitch composition for protecting electronic components.

Abstract

The present invention relates to an asphalt composition for protecting electronic parts, a preparation method thereof, and an electronic unit comprising the same. More specifically, the invention provides an asphalt composition for protecting electronic parts which comprises blown asphalt, petroleum wax or lion wax, and inorganic filler. The asphalt composition of the invention: provides water resistance and dust resistance to electronic parts; improves a heat radiation property, thereby improving the safety and durability of electronic products as a result; prevents force from being applied to electronic parts in which heating and cooling are repeated; and has an excellent effect of protecting electronic parts due to an excellent fixation property.

Description

technical field [0001] The present invention relates to a bitumen composition for protecting electronic components, a method for its preparation, and an electronic device comprising the bituminous composition. Background technique [0002] Intensive research is currently underway on methods of protecting electronic components from the outside. For example, a fluorescent lamp including a ballast should have a protection device having sufficient heat radiation properties as well as dust and water resistance. Also, in the case where light-emitting diodes (LEDs), which have recently attracted attention as lighting devices, are installed outside buildings, dustproofness and waterproofness of LED power sources are considered to be very important characteristics because they are compatible with The lifetime of the LED is directly related. [0003] Also, in the case of installing a power supply in a building where natural heat radiation (wind, air flow, etc.) is insufficient, the ...
