Detailed Description
The invention is further explained below with reference to the drawings:
referring to fig. 1 to 2, a silica gel damping sheet structure applied to a rear cover of a mobile phone battery comprises a base film 1, a silica gel damping layer 2 formed on one surface of the base film 1 through liquid silica gel curing, and a first release film 3 adhered to the other surface of the silica gel damping layer 2, wherein the first release film 3 and the silica gel damping layer 2 are peelable. The production process comprises the following steps: coating liquid silica gel on the surface of a base film 1, and curing at a high temperature to form a silica gel damping layer 2, wherein the curing temperature can be set to 100-150 ℃ usually, and the curing time is 10-30 minutes; after the silica gel damping layer 2 is formed, the other surface of the silica gel damping layer has slight viscosity, and the silica gel damping layer is adhered to the first release film 3 through the slight viscosity. The silica gel damping layer 2 formed by curing liquid silica gel has no air holes in the material, has high density and strong elasticity compared with silica gel foam, and can effectively reduce resonance when being attached to the inner surface of the rear shell of the mobile phone; base film 1 makes 2 non-deformable of silica gel damping layer to the tear resistance of silica gel damping layer 2 has been improved, be convenient for cut into different shapes according to the use scene moreover, simultaneously, the first slight viscidity that can protect 2 surfaces of silica gel damping layer from type membrane 3, can not adsorb the dust in the transportation storage process, and then this slight viscidity of accessible is directly pasted silica gel damping layer 2 in the mounting surface in the use, the cost is reduced and efficiency has been improved.
The base film 1 is PET, PE or PC material, first from type membrane 3 for fluoroplastic from type membrane or non-silicon from type membrane, first thickness from type membrane 3 is 25 ~ 75 mu m, the thickness of silica gel damping layer 2 is 0.1 ~ 2.0mm, base film 1 with can not peel off between the silica gel damping layer 2.
The thickness of the base film 1 is 25-75 μm. The thickness of base film 1 is thicker, and anti deformability and tear resistance are stronger, also are convenient for cut.
Preferably, a second release film 5 capable of being peeled is adhered to the other surface of the base film 1 through an adhesive layer 4, and the thickness of the second release film 5 is 25-75 μm. For scenes needing thinner silica gel damping sheets due to space limitation, the thinner base film 1 can be used for realizing the purposes of improving the tear resistance and facilitating cutting, improving the proportion of the silica gel damping layer 2 and ensuring the damping and noise reduction performance; simultaneously, peel off the back with the second from type membrane 5, the viscidity on usable silica gel damping fin two sides for it is more convenient to install, and accommodation is wider.
