Problems solved by technology

[0005] Such conventional acrylic foam tapes (10) have high elongation such that they have a tendency to be easily stretched during the die-cutting or punching process used to form such tapes into desired shapes or sizes
Therefore, it has poor processability, which is disadvantageous
Once traditional acrylic foam tape (10) is attached to a product, if it is separated or altered, it often happens that the acrylic foam is stretched cannot be reused

Embodiment 1

[0067] figure 2 is a cross-sectional view of a double-sided acrylic foam tape (20) having a base layer (PET layer) according to the first embodiment of the present invention. Such as figure 2 As shown, a base layer (24) is provided below the lower surface of the acrylic foam layer (22) having a thickness of 0.1 mm to 4 mm, and below the base layer (24), a pressure sensitive adhesive layer (26) is provided. Below the pressure-sensitive adhesive layer (26), a release film (28) is provided. Since the acrylic foam layer (22) itself is also self-adhesive, it functions as a double-sided adhesive tape. The acrylic foam layer (22) further serves as an impact absorbing layer due to its cushioning effect against external impact.

[0068]Hereinafter, a method for preparing a double-sided acrylic foam tape (20) having a base layer according to a first embodiment of the present invention is described. First, by utilizing functional acrylic acid (ester) monomers such as acrylic acid, an...

Embodiment 2

[0092] image 3 is a cross-sectional view of a double-sided acrylic foam tape (30) with a base layer according to a second embodiment of the present invention. Such as image 3 As shown, a base layer (34) is provided under the lower surface of the acrylic foam layer (32) having a thickness of 0.1mm-4mm, and under the base layer (34), a second pressure-sensitive adhesive layer (36) is provided. Below the second pressure sensitive adhesive layer (36), a release film (38) is provided. In order to achieve stronger adhesion, a first pressure sensitive adhesive layer (37) is provided on the upper surface of the acrylic foam layer (32). If desired, the first pressure-sensitive adhesive layer (37) may be mixed with various pigments (translucent, red, gray, etc.), or spices (eg, fruit, pine, herbs, etc.) may be added.

[0093] image 3 The preparation method of the shown double-sided acrylic foam tape (30) is similar to the method described in the foregoing Example 1, so a detailed...

Embodiment 3

[0095] Figure 4 is a cross-sectional view of a double-sided acrylic foam tape (40) with a base layer according to a third embodiment of the present invention. Such as Figure 4 As shown, the base layer (44) is provided under the lower surface of the first acrylic foam layer (42) having a thickness of 0.2 mm to 0.6 mm, and under the base layer (44), a second acrylic foam layer ( 43). Below the second acrylic foam layer (43), a release film (48) is provided.

[0096] Figure 4 The preparation method of the shown double-sided acrylic foam tape (40) is similar to the method described in the foregoing Example 1, so a detailed description of the preparation method is omitted here.

Abstract

The present disclosure provides a double sided acrylic foam tape having a base layer and a double sided acrylic foam tape using the same, for mobile phone use. Specifically, the present disclosure provides a double sided acrylic foam tape, comprising: an acrylic foam layer with a certain thickness; a base layer formed on either side of the acrylic foam layer; a pressure sensitive adhesive layer formed on one side of the base layer; and a release film formed on the pressure sensitive adhesive layer.

Description

[0001] related application [0002] This application claims the benefit and priority of Korean Patent Application No. 10-2006-0134778, filed December 27, 2006, and U.S. Application No. 11 / 829,427, filed July 27, 2007, the entire contents of which are adopted Incorporated by reference. technical field [0003] The present invention relates to a double-sided acrylic foam tape (double-sided acrylic foam tape), in particular to a double-sided acrylic foam tape with a base layer (or base layer) and a double-sided acrylic foam tape using the base layer Base layer double sided acrylic foam tape for mobile phone applications. Background technique [0004] Figure 1 is a cross-sectional view of a conventional acrylic foam tape (10). As shown in FIG. 1, the conventional acrylic foam tape (10) is composed of an acrylic foam layer (12) with a certain thickness and a release film (14). [0005] Such conventional acrylic foam tapes (10) have high elongation such that they tend to be eas...
