Abstract

The invention provides a super-hydrophobic micro-extinction surface protecting film and a preparation method and an application method thereof. The super-hydrophobic micro-extinction surface protecting film comprises a hydrophobic layer, a micro-extinction layer and an adhesive layer. The adhesive layer is an acrylic acid series adhesive, the micro-extinction layer is compound filler comprising silicon dioxide and titanium dioxide, and the hydrophobic layer is a fluorine-containing silane coupling agent treatment layer; the acrylic acid series adhesive is polymerized by adopting active free radicals, and the polydispersity index is smaller than 2.5; by matching silicon dioxide and titanium dioxide for the micro-extinction layer, the adhesive is selection of special composition. By means ofthe selection, effects of excellent comprehensive performances with hydrophobic property, micro-extinction, adhesiveness and without residues are achieved.

Description

technical field [0001] The invention relates to the field of surface protection films, in particular to the field of a surface protection film with superhydrophobicity and micro-extinction properties, and also to the field of a preparation method and a use method of a surface protection film with super-hydrophobicity and micro-extinction properties. Background technique [0002] The surface protective film is an optical film used to protect the adherend. It is widely used in life and work, such as: mobile phone screen protective film, TV screen protective film, electrical appliance protective film, etc. In the above fields, it can also be used for the protection of vehicles, such as the surface protection of rearview mirrors, to prevent other dirt from damaging the rearview mirrors. [0003] For the use of daily rearview mirrors, it will be found that in rainy days, there will be a large amount of water residue on the surface, which will affect the observation of the rear ca...
