Description

Technical Field

[0001] The invention belongs to the technical field of key caps, and particularly relates to an anti-sweat key cap and a preparation method thereof. Background Art

[0002] A key cap is a small plastic cap-shaped part that snaps onto the top of a keyboard key. It is marked with the function or number or letter symbol of the corresponding key. The key cap is an important part of a mechanical keyboard and is directly related to the feel, service life, and appearance of the keyboard. The main function of the key cap is to protect the keyboard's circuit board from dust and dirt while providing a comfortable typing experience. Key caps are usually made of different materials, such as ABS and PBT, which directly affect the durability, feel, and typing sound of the key caps.

[0003] Mechanical keyboards are mostly used in gaming and e-sports, and players usually tap the keycaps at a high frequency during the competition. Existing plastic keycaps are less comfortable, and players' fingers tend to sweat after long-term tapping, which further affects the player's own operating level and gaming experience. Therefore, the present invention proposes an anti-sweat keycap for a mechanical keyboard and a preparation method thereof. Summary of the invention
