Description of drawings
Fig. 1 is the structural representation of novel foam adhesive tape of the present invention.
Embodiment
The present invention will be further elaborated below by embodiment:
Present embodiment provides a kind of novel foam adhesive tape (as shown in Figure 1), comprises sealing coat 1, first adhesive layer 2, first stratum basale 3, second adhesive layer 4, foam layer 5, the 3rd adhesive layer 6, second stratum basale 7 and the 4th adhesive layer 8 successively from one side to the another side of adhesive tape.
The total thickness of described novel foam adhesive tape is no more than 400 μ m.The material of sealing coat 1 is two-sided release paper, PE or PET, the off-type force of sealing coat 1 is 5～100g, preferred 10～30g, second adhesive layer 4 and the 3rd adhesive layer 6 are vinylformic acid system glue, first adhesive layer 2 and the 4th adhesive layer 8 are the removable non-setting adhesive glue of vinylformic acid system.The gluing dry measure of described second adhesive layer 4 and the 3rd adhesive layer 6 is no more than 40g/m
2, the gluing dry measure of first adhesive layer 2 and the 4th adhesive layer 8 is 30～100g/m
2, preferred 40～60g/m
2, its 90 ° of peeling forces are greater than 1.5kg/25mm.The material of described foam layer 5 is PE, EVA or is these two kinds of mixtures of material, also can be the foam carrier with the blend of PP, PU or these two kinds of materials.The thickness of described foam carrier is 50～200 μ m, and frothing percentage is 1～10 times, preferred 1～5 times.This foam carrier needs pre-treatment before use, and common method is corona treatment, and described foam carrier surface wettability tension force is greater than 42nN/m.The material of described first stratum basale 3 and second stratum basale 5 is the PET film, and its thickness is 4～50 μ m.First stratum basale 3 and second stratum basale 5 select for use the chemical ingredients, thickness of film can be identical can be different.The basilar membrane color is transparent, and pigmentable is grey, white, black or other colors, and black is especially favourable, can reduce or eliminate adhesive tape to the transmitance of light.Basilar membrane need carry out pre-treatment before using, and common method is corona and etching.
Below we embody excellent part of the present invention better by several experiments.
Experiment one: tensile strength experiment
The insolated layer materials of the novel foam adhesive tape that adopts in this experiment is red PE film, the light face of off-type force is 5-10g, heavy face is 20-25g, second adhesive layer 4 and the 3rd adhesive layer 6 are vinylformic acid system glue, and first adhesive layer 2 and the 4th adhesive layer 8 are the removable non-setting adhesive glue of vinylformic acid system.The gluing dry measure of described second adhesive layer 4 and the 3rd adhesive layer 6 is 30g/m

2The material of described foam layer 5 is the foam carrier with PE.The thickness of described foam carrier is 150 μ m, and frothing percentage is 5 times.The material of described first stratum basale 3 and second stratum basale 5 is the PET film.The adhesive tape substrate thickness that adopts in this experiment is followed successively by 5um, 12um, 25um, 36um, 50um, and we will test successively to the adhesive tape of these different thickness.
The novel foam adhesive tape of above-mentioned specification is carried out the intensity Elongation test, and test obtains following experimental data:
In the above table clearly the difference place of the present invention and existing foam adhesive tape as can be seen, be higher than in tensile strength under the situation of tens times on existing foam adhesive tape, elongation only is 1/twenties of existing foam adhesive tape.As seen novel foam adhesive tape of the present invention possesses the characteristics of high tensile low elongation.
Experiment two: peel off results from residue tests
In order to highlight effect, distinguish that easily the novel foam adhesive tape here is white, by the square black plastic box of applying thing 10cm*10cm, the box surface is divided into 10*10 dice zone.
We prepare the box of 10 same sizes respectively, are labeled as box one, box two, box three, box four, box five, box six, box seven, box eight, box nine and box ten respectively.
The foam adhesive tape of the novel white of same size is fitted in five box surfaces simultaneously, and all fitted in the surface of five boxes.After a period of time the adhesive tape on box surface is torn.In order to make this experiment have cogency, adopt the unified method of tearing in the time of tear tape, pull adhesive tape at the uniform velocity outward to the diagonal angle from the adhesive tape that an angle of box is located, observe the area percentage of estimating to remain in box remained on surface adhesive tape then respectively.
Be the data form of experiment below:
| Pasted subject matter | The applying time | Residual per-cent |
| Box one | 1 hour | 0% |
| Box two | 2 hours | 0% |
| Box three | 4 hours | 0% |
| Box four | 6 hours | 0% |
| Box five | 8 hours | 0% |
| Box six | 12 hours | 0% |
| Box seven | 24 hours | 0% |
| Box eight | 36 hours | 0% |
| Box nine | 48 hours | 0% |
| Box ten | 72 hours | 0% |
Can find out significantly that from above table the present invention does not have the excellent specific property of cull when tear in quilt applying thing surface.
By above-mentioned experiment, can find out clearly that novel foam adhesive tape provided by the invention possesses high tensile strength and elongation, cut edge smooth when die-cut and cracky not, the present invention also has long-time reworking in addition, can not stay any glue trace and cull behind the heavy industry on the affixed object surface, and the tape performance that strips down does not have the decline of much degree, still can reuse repeatedly.
Although be the example purpose, preferred implementation of the present invention is disclosed, but those of ordinary skill in the art will recognize that under situation about not breaking away from by the disclosed scope and spirit of the present invention of appending claims, various improvement, increase and replacement are possible.
