Embodiment 1

[0027] refer to figure 1 , an aluminum foil adhesive tape, including a first release film layer 1 and a second release film layer 2 symmetrically arranged, and the first release film layer 1 and the second release film layer 2 are fixedly bonded on the opposite side of the second release film layer. An adhesive layer 3 and a second adhesive layer 4 are used to enhance the bonding ability of the adhesive tape. The side of the first adhesive layer 3 away from the first release film layer 1 is fixedly bonded with a first insulating layer 5 for enhancing the adhesive tape insulation capacity;

[0028] In the present invention, the side of the second adhesive layer 4 away from the second release film layer 2 is fixedly bonded with a second insulating layer 6 for enhancing the insulating ability of the adhesive tape, and the first insulating layer 5 is away from the side of the first adhesive layer 3. One side is fixedly bonded with a first flame retardant layer 7, and the side of ...

Embodiment 2

[0035] refer to figure 1 , aluminum foil adhesive tape, including a symmetrical arrangement of the first release film layer 1 and the second release film layer 2, the first release film layer 1 and the second release film layer 2 are PE release film, PET release film One of film, OPP release film, PC release film, PS release film, PMMA release film, to enhance the protection ability of the release film layer;

[0036] The opposite sides of the first release film layer 1 and the second release film layer 2 are fixedly bonded with a first adhesive layer 3 and a second adhesive layer 4, which are used to enhance the bonding ability of the adhesive tape. The first adhesive layer 3 and the second adhesive layer 4 are both thermoplastic elastomer pressure-sensitive adhesives, acrylate pressure-sensitive adhesives, and polyvinyl ether pressure-sensitive adhesives, which enhance the bonding ability of the adhesive layer, and the first adhesive layer 3 is far away from the first separa...

Abstract

The invention discloses an aluminum foil adhesive tape and a preparation method thereof. The aluminum foil adhesive tape comprises a first release film layer and a second release film layer which are symmetrically arranged, wherein a first adhesive layer and a second adhesive layer are fixedly bonded to the opposite sides of the first release film layer and the second release film layer, and a first insulating layer is fixedly bonded to the side, which is away from the first release film layer, of the first adhesive layer. The preparation method comprises the steps of S1, selecting aluminum foil to prepare a base layer; S2, adding a seed emulsion into a reactor protected by nitrogen, stirring while heating to the temperature of 80 DEG C, starting to dropwise add the pre-emulsion, starting to replenish a 10wt% aqueous solution of sodium hydrogen sulfite, heating to the temperature of 85 DEG C, keeping the temperature for 3 hours, then cooling to room temperature, adjusting the pH value to 8-9 by using ammonia water, and filtering to obtain an adhesive layer; S3, selecting a release material to prepare a release film layer; and S4, selecting silica gel glass fabric to prepare a flame-retardant layer. Through the arrangement of the multi-layer structure, the flame-retardant and insulating capabilities of the adhesive tape are improved, so that the use effect of the adhesive tape is improved.

Description

technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to an aluminum foil adhesive tape and a preparation method thereof. Background technique [0002] Aluminum foil tape, using high-quality pressure-sensitive adhesive, good viscosity, strong adhesion, anti-aging and other effects, greatly improved thermal insulation performance, specifications are available in various widths and lengths, aluminum foil tape is pasted with all aluminum foil composite material seams, heat preservation nails puncture It is the main raw and auxiliary materials for refrigerator and freezer manufacturers, and it is also a must-buy raw material for thermal insulation material distribution departments.
