DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, a stretch-resistant and anti-warping foam tape includes a foam layer 1, characterized in that: a reinforcing component 2 is installed outside the foam layer 1, the reinforcing component 2 includes a connecting layer 201 bonded to the top outer wall of the foam layer 1, a connecting layer 202 bonded to the bottom outer wall of the foam layer 1, a plurality of reinforcing fibers 1 203 are arranged inside the connecting layer 1 201, a plurality of reinforcing fibers 2 204 are arranged inside the connecting layer 202, and the reinforcing fibers 1 203 and the reinforcing fibers 2 204 are staggered.

[0025] The connecting layer 1 201 can connect multiple reinforcing fibers 1 203 into a whole, and the connecting layer 202 can connect multiple reinforcing fibers 2 204 into a whole, so that the positions of the multiple reinforcing fibers 1 203 and the multiple reinforcing fibers 2 204 are fixed, and the distribution is sufficiently uniform to ensure the tensile strength. The reinforcing fibers 1 203 and the reinforcing fibers 2 204 are staggered to ensure that the tape can withstand tension in different directions, thereby making the tape stronger as a whole.

[0026] like Figure 3 and Figure 4 As shown, an anti-warping component 6 is installed outside the foam layer 1, and the anti-warping component 6 is located at both ends of the foam layer 1.

[0027] The anti-warping component 6 includes two surrounding parts 301 arranged on the outer walls at both ends of the connecting layer 1 201, and the two surrounding parts 301 respectively surround the outer walls at both ends of the foam layer 1. An extension part 302 is arranged on the outer walls at both ends of the connecting layer 202, and the edges of the two surrounding parts 301 are respectively kept flush with the edges of the two extension parts 302.

[0028] The surrounding parts 301 arranged at both ends of the connecting layer 201 can protect the outside of the foam layer 1 and prevent the foam layer 1 from aging as much as possible. The surrounding parts 301 extend to both ends of the foam layer 1, and cooperate with the extension parts 302 to ensure that the cross-sectional thickness of the foam layer 1 is small enough, so that the side of the foam layer 1 is less likely to be impacted by external forces and is less likely to warp.

[0029] like Figure 1 and Figure 2 As shown, the top outer wall of the connecting layer 1 201 is provided with an adhesive layer 1 3 , and the bottom outer walls of the connecting layer 202 and the two extension parts 302 are provided with an adhesive layer 2 5 .

[0030] like Figure 1 and Figure 2 As shown, the outer wall of the bottom of the adhesive layer 5 is covered with a release film 4. When the tape is wound together, the tape can be wound under the action of the release film 4.

[0031] like Figure 1 and Figure 2 As shown, the connection layer 1 201, the connection layer 202, the two surrounding parts 301 and the two extension parts 302 are all made of polyethylene material.

Neoprene rubber glue is an adhesive with excellent viscosity and adaptability. It has strong viscosity, is suitable for a variety of substrates, is heat-resistant, water-resistant, and has a long service life.

[0033] The utility model provides an anti-stretching and anti-warping foam tape, and the specific working principle is as follows:

The reinforcing fibers 1 203 and the reinforcing fibers 2 204 are staggered to ensure that the tape can withstand tension in different directions, thereby making the tape stronger as a whole. The surrounding parts 301 set at both ends of the connecting layer 1 can protect the outside of the foam layer 1 and avoid aging of the foam layer 1 as much as possible. The surrounding parts 301 extend to both ends of the foam layer 1, and cooperate with the extension parts 302 to ensure that the cross-sectional thickness of the foam layer 1 is small enough, so that the side of the foam layer 1 is less likely to be hit by external forces and is less likely to warp.
