Therefore, it is a problem to be solved in the art to provide a sealing tape having good adhesive property and excellent flame retardant property.

In view of the problems in the prior art, the present invention aims to provide an adhesive, a packaging tape comprising the same, and applications thereof. The adhesive has good bonding performance and excellent flame retardance, and the packaging adhesive tape prepared by using the adhesive can be used for directly hot-pressing and packaging the power battery heat-insulating buffer gasket in a short time, so that the power battery heat-insulating buffer gasket has excellent insulativity and flame retardance. In order to achieve the purpose, the invention adopts the following technical scheme:

Performance testing
The following performance tests were performed on the sealing tapes provided in application examples 1 to 9 and application comparative examples 1 to 7:
(1) adhesive Strength (N/mm)
Cutting the adhesive tape into strips with the width of 10mm, the size of 10mm multiplied by 125mm, laminating and pressing for 600s under the conditions of high temperature of 160 ℃ and pressure of 1Mpa, recovering to the room temperature of 25 ℃ for 10 minutes, testing the bonding strength between the adhesive tape and the silica gel pad with the bottom coating, the unit N/mm, testing according to a standard angle of 180 degrees, and the peeling speed is 100 mm/min.
(2) Breakdown voltage (Kv)
The adhesive tape is cut into samples with the size of 100mm multiplied by 100mm, the samples are clamped between two metal electrodes, the diameter of an electrode 1 is 25mm, the height of the electrode is 25mm, the diameter of an electrode 2 is 75mm, the height of the electrode is 15mm, the two electrodes are coaxially placed and soaked in transformer oil, and the boosting rate is 1 Kv/s.
(3) Tensile strength (Mpa)
The tape was cut into a 100mm × 10mm sample piece along the direction of the reel, and the sample piece was pulled and stretched by a universal pulling machine until the tape was broken at a rate of 300 mm/min.
(4) Flame retardancy
Baking the adhesive tape at the high temperature of 150 ℃ for 60min, cooling to room temperature, cutting into samples with the length of 200mm and the width of 50mm, burning according to the UL94 standard, and judging the flame retardant grade according to the standard. The final data for each performance test is shown in table 2.
TABLE 2
As can be seen by comparing application example 1 with application comparative examples 6 and 7, the amount of the flame retardant needs to be controlled within a reasonable range when the material is prepared, otherwise, the contradiction between the bonding strength and the flame retardant property exists; as can be seen from application example 1 and application comparative examples 4 and 5, the organic phosphorus flame retardant and the nitrogen flame retardant selected in the present invention have a synergistic interaction effect, and if the organic phosphorus flame retardant and the nitrogen flame retardant are replaced with other flame retardants, the flame retardant effect and the bonding strength of the present invention cannot be achieved, and meanwhile, as can be seen from comparison between application example 1 and application examples 4 and 5, the mass ratio of the organic phosphorus flame retardant to the nitrogen flame retardant affects the bonding strength of the material, and when the mass ratio of the organic phosphorus flame retardant to the nitrogen flame retardant in the adhesive is 3:1, the flame retardant performance of the obtained material is poor; as is clear from comparison of application example 1 with application examples 6 and 7, when the mass ratio of the base resin to the tackifier resin in the adhesive is too large or too small, the adhesive strength is reduced; comparing application example 1 with application examples 8 and 9, it is understood that when the thickness of the adhesive layer is more than 40 μm, the flame retardant effect is good but the adhesive strength is lowered due to a large flash amount at the time of hot pressing.
In conclusion, after a certain amount of organic phosphorus flame retardant and nitrogen flame retardant are added, the packaging tape prepared by the adhesive is reasonably matched with the matrix resin and the tackifying resin at the same time and is coordinated with each other, so that the bonding strength of the packaging tape can reach 1.5N/mm; meanwhile, the adhesive has a good flame retardant effect, and through the mutual matching of the selected flame retardant and the resin, the packaging adhesive tape provided by the invention has the advantages of good flame retardant effect and good physical property, is suitable for packaging of a cushion pad in a lithium battery, and is beneficial to industrial application.
