Dust-purifying adhesive layer, dust-purifying film, and dust-purifying film sleeve

A dust-purifying film comprising:

• a dust-purifying adhesive layer, and
• a protective layer,
• the dust-purifying adhesive layer comprising:
• a substrate layer,
• an optically clear adhesive (OCA) layer, and
• a dust-purifying layer adapted for dust-purifying and air bubbles elimination, the dust-purifying layer and the OCA layer respectively disposed on two sides of the substrate layer, wherein the protective layer is attached to the OCA layer,
• the dust-purifying layer has fluidity, and
• when the dust-purifying layer is arranged on a screen with foreign matters of an electronic device, the dust-purifying layer wraps the foreign matters on the screen and fills gaps formed between the foreign matters and the dust-purifying layer,
• wherein a material of the dust-purifying layer comprises the following components mixed by weight ratio:
• 28%-35% methyl vinyl silicone rubber, 55%-65% ethyl formate, 8%-12% xylene and 1.5%-2.5% ethylbenzene.
