Effect and service life are all effectively promoted；The two-sided compound cutan can be widely used in various protecting film of mobile phone screen
In, so that the quality of protecting film of mobile phone screen is higher, pad pasting operates simpler, bubble-free, and non-breakable, pad pasting effect obtains greatly
Big promotion.
Detailed description of the invention
Fig. 1 is the cross section structure schematic diagram of double-sided adhesive film described in one embodiment of the utility model；
Fig. 2 is the cross section structure schematic diagram of protecting film of mobile phone screen described in one embodiment of the utility model.
Wherein: acrylic gel coating 1, polyethylene terephthalate film 2, silica-gel coating 3, surface layer film 10.
Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, a kind of double-sided adhesive film, successively includes: acrylic gel coating 1 to bottom, gathers to benzene from top layer
Dioctyl phthalate second diester film 2 and silica-gel coating 3.
The acrylic gel coating 1 is that the painting of acrylic glue is located at polyethylene terephthalate film 2 by coating process
Upper surface, the acrylic glue is current material, main ingredient are as follows: dual-component polyurethane resin, antioxidant, thickening
Agent, elastomer and butanone.
The layer of silica gel is that the painting of acrylic glue is located at 2 lower surface of polyethylene terephthalate film by coating process
, the silica gel is current material, main ingredient are as follows: cyanacrylate, elastomer, tackifier, thickener, toughening
Agent, polymerization inhibitor and butanone.It is in the prior art generally that layer is carried out using pressure-sensitive silica gel in the middle layer of protecting film of mobile phone screen
Between bond, the silica-gel coating 3 is coated with using coating process in the present embodiment, 3 quality of silica-gel coating is more uniform can be with
It is directly bonded with mobile phone screen, and the quick-replaceable of more convenient protecting film of mobile phone screen.
The polyethylene terephthalate thin film, smooth surface is glossy, has in wider temperature range excellent
Physical mechanical property, highest Applicable temperature can reach 120 DEG C, and electrical insulating property is excellent, or even under high-temperature high-frequency, creep resistant
Property, fatigue durability, rub resistance, dimensional stability are all fine, organic solvent-resistant and good weatherability, it is ensured that safeguard film for cellular phone
It is used for a long time.
Specifically, the polyethylene terephthalate film 2 with a thickness of 10-32 μm, preferably 10 μm；Acrylic gel coating
1 with a thickness of 10-32 μm, preferably 12 μm；Silica-gel coating 3 with a thickness of 10-32 μm, preferably 12 μm.Due to the translucency of material,
