Problems solved by technology

[0002] During the long-term wear of the earphones, because the earplugs of the earphones are in contact with the skin for a long time, they are prone to sweating and cannot be removed. The earplugs are prone to breed bacteria, which seriously endangers human health, especially those with sensitive skin. possible other complications
[0003] In the existing technical solutions, antibacterial agents, including aseptic antibacterial agents, are added during the molding process of silica gel. In order to achieve a certain antibacterial effect, the proportion of inorganic antibacterial agents added is generally 5wt%~10wt%. A higher proportion of aseptic antibacterial agents The amount added will affect the original performance of silica gel, mechanical properties, skin-friendly comfort and other hidden dangers.

Embodiment 1

[0033] Embodiment one: if figure 1 As shown, an earphone earplug includes an earplug body 1, the earplug body 1 is an antibacterial silicone earplug, the antibacterial silicone earplug is made of antibacterial silicone, the outer surface of the earplug body 1 is covered with a nano antibacterial protective film, The thickness of the antibacterial protective film is 5-50nm, and its preferred thickness is 22nm; the nano-antibacterial protective film is a PECVD coating, which not only has a good antibacterial effect, is not easy to breed bacteria, and is resistant to salt spray corrosion, sweat corrosion, and abrasion resistance. The treated earplug cover is soft and comfortable to wear, and while bringing beautiful and pleasant music to the user, the ear comfort is also satisfied.

Embodiment 2

[0040] Embodiment 2: The difference from Example 1 is that the antibacterial silica gel contains the finished antibacterial agent, and the antibacterial silica gel includes 6wt% of the finished antibacterial agent by weight percentage, and the antibacterial silica gel includes all the antibacterial agent by weight percentage. Said nano antibacterial agent 1.8 wt%. The finished antibacterial agent includes 270wt% of the porous antibacterial agent carrier by weight percentage.

[0041] The nano-antibacterial agent is a combination of two metal-based antibacterial agents, the nano-antibacterial agent is a combination of a silver-based antibacterial agent and a nickel-based antibacterial agent, or the nano-antibacterial agent is a combination of a silver-based antibacterial agent and a titanium-based antibacterial agent. Combination, or the nano antibacterial agent is the combination of the nickel-based antibacterial agent and titanium-based antibacterial agent.

Embodiment 3

[0042] Embodiment 3: The difference from Example 1 is that the antibacterial silica gel includes the finished antibacterial agent, and the antibacterial silica gel includes 0.83wt% of the finished antibacterial agent by weight percentage, and the finished antibacterial agent includes antibacterial agent and Porous antibacterial agent carrier, the antibacterial silica gel includes 0.5 wt% of the antibacterial agent by weight percentage.

[0043] The finished antibacterial agent includes 240wt% of the porous antibacterial agent carrier by weight percentage.

[0044] The nano antibacterial agent is a combination of two metal-based antibacterial agents, and the antibacterial agent is a combination of silver-based antibacterial agents, nickel-based antibacterial agents, and titanium-based antibacterial agents.

[0045] The present invention also relates to a preparation method of earphone earplugs:

[0046] Specifically include the following steps:

Abstract

The invention provides an earphone earplug, which comprises an earplug body, the earplug body is an antibacterial silica gel earplug, the antibacterial silica gel earplug is made of antibacterial silica gel, the antibacterial silica gel comprises an antibacterial agent finished product, the antibacterial silica gel comprises 0.04 wt%-6wt% of the antibacterial agent finished product, the antibacterial agent finished product comprises a nano antibacterial agent and a porous antibacterial agent carrier, and the antibacterial silica gel comprises 0.03 wt%-1.8 wt% of the nano antibacterial agent in percentage by weight; the antibacterial agent finished product contains the porous antibacterial agent carrier which has an ultrahigh specific surface area, so that the dispersion of effective components of the antibacterial agent is facilitated, the surface contact property of the antibacterial agent is greatly improved, the utilization rate of the inner surface of the antibacterial agent is improved, and the adding proportion of the antibacterial agent is greatly reduced; the addition amount of the antibacterial agent is low, the problem that the original performance of the silica gel can be influenced by the addition amount of the antibacterial agent with a high proportion is solved, and bad hidden dangers such as the mechanical performance and the wearing skin-friendly comfort of the antibacterial earplug are avoided.

Description

technical field [0001] The invention relates to an earplug, in particular to an earphone earplug and a preparation method thereof. Background technique [0002] During the long-term wear of the earphones, because the earplugs of the earphones are in contact with the skin for a long time, they are prone to sweating and cannot be removed. The earplugs are prone to breed bacteria, which seriously endangers human health, especially those with sensitive skin. Other complications may arise. [0003] In the existing technical solutions, antibacterial agents, including aseptic antibacterial agents, are added during the molding process of silica gel. In order to achieve a certain antibacterial effect, the proportion of inorganic antibacterial agents added is generally 5wt%~10wt%.
