Abstract

The invention discloses a waterproof adhesive tape, which comprises from top to bottom: a first isolation layer, a first acrylic adhesive layer, a first black thermoplastic elastomer layer, a first primer layer, a base material layer, and a second primer layer layer, a second black thermoplastic elastomer layer, a second acrylic adhesive layer, and a second release layer. The invention also discloses a preparation method of the waterproof tape and electronic products containing the waterproof tape. The waterproof adhesive tape of the invention has excellent water resistance, cushioning properties and light-shielding properties, and can be applied to permanent bonding of electronic component frames.

Description

Technical field [0001] Technical Field The present invention relates to tape, in particular to a waterproof tape, a preparation method and electronic products comprising the waterproof tape. Background technique [0002] The rapid development of the electronics industry, a variety of tape is used in computers, mobile phones and other electronic products, for temporary or permanent fix to replace the original mechanical fixing or welded internal elements fixed. Electronic components with tape border has always been a huge market, especially in the flat, notebooks and monitors and other border adhesive. [0003] Border adhesive tape addition to playing the role of a solid, it also needs to play a functional role other. The first is a light-blocking in the vertical direction to prevent the screen light leakage, black is the best choice; followed by cushioning properties, in order to reduce the distance of the electronic product has been dropped or shelved damage generated during use...
