Abstract

The invention provides a surface protective film for a mobile phone lens. The surface protective film orderly comprises an antifouling coating layer (1), a tackifying layer (2), a polymer film layer (3), a tackifying layer (2'), an outer ring water-absorbing binder layer (4) and a stripping gasket (5). The polymer film layer (3) is an ABS film having thickness of 80-150 microns. The outer ring water-absorbing binder layer (4) comprises an external rim zone (A) and 80-90% of an inner zone (B) on the basis of the area. The surface protective film solves the problem that the lens is easy to pollute, is not waterproof, has paving difficulty, and has excellent antifouling properties (water and oil repellency), water repellency, low residues, and good paving properties.

Description

technical field [0001] The invention relates to the field of surface protection films, in particular to the field of surface protection films for mobile phone lenses, in particular to the field of small-sized surface protection films for mobile phone lenses. Background technique [0002] With the advancement of science and technology, the penetration rate of mobile phones is gradually increasing. All mobile phones have camera functions. The pollution of the mobile phone lens and the situation of water entering from the lens are gradually increasing. However, how to protect the lens part has not attracted the attention of scientific and technological workers. There are few reports on the protection of mobile phone lenses in the prior art. Utility model 201521009639.2 reports a lens protective film, which mainly focuses on the modification of the structure improvement to the overflow performance, and does not involve the above problems. [0003] Based on the above problems, t...
