Abstract
The invention discloses a dust-proof plug with shielding function and a preparation method thereof. The dust-proof plug includes a dust-proof plug body, a conductive layer coated on the dust-proof plug body, a dust-proof plug body and a Between the conductive layers and through crosslinking and curing, the conductive layer and the dust plug body are combined into an adhesive layer; the adhesive layer includes the following raw materials in parts by mass: 100 parts of EPDM glue, 2-2 10 parts, 2-10 parts of stearic acid, 10-300 parts of reinforcing carbon black, 0.2-5 parts of triethanolamine, 0.2-10 parts of accelerator, 0-10 parts of sulfur, 0.5-20 parts of tackifier and 50 parts of solvent ‑10000 copies. In the dustproof plug of the present invention, the conductive layer is compounded on the outer periphery of the dustproof plug body through an adhesive layer, which endows the dustproof plug with a shielding function and resistance to plugging and unplugging, and satisfies the use of ports on electronic, communication and other equipment.
Description
technical field [0001] The invention relates to a dustproof plug, in particular to a dustproof plug with shielding function and a preparation method thereof. Background technique [0002] At present, the dust-proof plugs used in ports on electronic equipment, communication equipment, etc. usually only have a dust-proof function and do not have a shielding function. With the development of products, especially the development of 5G, there are requirements for port shielding. The dust-proof plug made of metal-filled conductive adhesive is not resistant to plugging and unplugging, and has a short service life. Therefore, it is necessary to design a material that is resistant to plugging and has shielding and dustproof functions to solve the above problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a plug-resistant dust plug with shielding function and a preparation method thereof. [0004] The technical solu...
