Problems solved by technology

[0005] However, in such a case, it may be difficult for conventional rubber or silicone to maintain its shape (regularity), and as a result, it may be difficult to perform assembly work with conventional rubber or silicone
As a result, the assembly of conventional waterproof parts may result in poor work efficiency
Also, rubber or silicone may elongate due to their malleability, which may cause inconsistent shapes
Therefore, with long-term use, the water resistance may gradually decrease due to these reasons

Embodiment 1

[0044] Considering the NC machining width of a 125×47 shape, a 140×60 mm shape was machined to a depth of 0.5 mm in a 220×200 mm mold into which a UV resin solution (2004e, commercially available from Mirae C&P, Korea) was injected. Place a 300μm thick PC sheet to cover the UV resin solution, and then use a 250mm roller at 2kgf / cm 2 The pressure is compressed back and forth. The sheet was cured by irradiating the sheet with a 900J UV lamp for 10 seconds to produce a top UV resin layer. The cured top UV resin layer was removed from the mold, followed by a second injection of the UV resin solution into the mold. The PC sheet with the UV resin layer was placed on the second UV resin solution, then compressed, and then irradiated with a UV lamp for 10 seconds to cure to obtain a bottom UV resin layer, thereby assembling a waterproof part with a sandwich structure.

[0045] The produced waterproof member was NC processed to seal the gap formed between the upper case and the lower...

Abstract

The invention relates to a waterproof member and method of producing the same.The waterproof member includes a polymer sheet and a UV resin layer adhered to the polymer sheet. A method of producing a waterproof member includes injecting a first UV resin solution into a first resin molding, placing a polymer sheet onto the first UV resin solution, compressing the polymer sheet and the first UV resin solution to be closely adhered to each other, curing a first UV resin layer on the polymer sheet by irradiating UV into the first UV resin solution, injecting a second UV resin solution into a second resin molding, placing a polymer sheet having the first UV resin molding onto the second resin molding, compressing the polymer sheet and the second UV resin solution to be closely adhered to each other, and curing a second UV resin layer on the polymer sheet by irradiating UV into the second UV resin solution.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and the benefit of Korean Patent Application No. 10-2010-0122458 filed December 3, 2010, which is incorporated by reference for all purposes as if fully set forth herein. technical field [0003] The invention relates to a waterproof component and a manufacturing method thereof. More particularly, the present invention relates to a waterproof part for protecting internal parts of a mobile terminal from moisture and a method of manufacturing the waterproof part. Background technique [0004] Generally speaking, electronic products, especially mobile terminals, can be used freely without being affected by the position of the user when moving. The use of mobile communication terminals, such as cell phones and personal digital assistants (PDAs), called personal portable terminals, is gradually increasing due to the convenience of use. However, since the mobile terminal is generally used w...
