Problems solved by technology

This kind of adhesive tape is laminated by multi-layer structure, the upper layer is the substrate layer, the lower layer is the release material layer, and the acrylic foam glue is used in the middle, which has the function of blocking water and water, but the water blocking effect is not obvious, and it is hair The foam material is relatively thick and hard, and the adhesion is not good. It is easy to deform after aging, and the corners are easy to bulge due to overlapping.

Embodiment 1

[0019] Example 1. 100 parts of butyl rubber, 25 parts of tackifying resin T-803L, added toluene to dissolve into a solution, coated on the release film, the thickness of the dry glue is 50 μm, and transferred to a PVC substrate with a thickness of 100 μm after drying (Insulation buffer PVC film) to make tape products.

Embodiment 2

[0020] Embodiment 2. 75 parts of butyl rubber, 25 parts of EPDM, 25 parts of tackifying resin FTR6100, add toluene and dissolve into a solution, coat the release film, the dry glue thickness is 50 μm, transfer to On a PVC base material (insulating buffer PVC film) with a thickness of 100 μm, an adhesive tape product was prepared.

Embodiment 3

[0021] Example 3. 75 parts of butyl rubber, 25 parts of isobutyl rubber, 25 parts of tackifying resin GB-100, add toluene to dissolve into a solution, coat the release film, the thickness of the dry glue is 50 μm, and transfer to the thickness after drying Tape products were prepared on a 200 μm PVC substrate (insulating buffer PVC film).

Abstract

The invention discloses a high-watertightness solar module edge-sealing adhesive tape, comprising a base material layer, a functional adhesive layer and a release material layer arranged in succession from top to bottom.The functional adhesive layer is formed by: dissolving rubber adhesive in an organic solvent to form a solution and applying the solution to the release material layer; the adhesive tape is characterized in that the rubber adhesive is made from the following components according to parts by weight: 80-120 parts of a main agent and 20-30 parts of a viscosifier, wherein the main agent at least comprises butyl rubber.Since the rubber adhesive in the middle functional adhesive layer uses the butyl rubber of high watertightness as the main agent, watertightness of the whole adhesive tape is greatly enhanced; in the adhesive tape compared with original acrylic foam adhesive, the adhesive layer formed by curing of butyl rubber is better in softness and application performance, and thereby, this adhesive layer is imparted same bonding force through only half of usage of original acrylic foam adhesive, helping reduce overall thickness of the adhesive tape.

Description

technical field [0001] The invention belongs to the technical field of PSA, and in particular relates to a high-resistance water-based solar module edge-sealing adhesive tape. Background technique [0002] At present, solar modules, such as various photovoltaic cell products, are designed with special edge-sealing tapes to connect and strengthen glass edges. This kind of adhesive tape is laminated by multi-layer structure, the upper layer is the substrate layer, the lower layer is the release material layer, and the acrylic foam glue is used in the middle, which has the function of blocking water and water, but the water blocking effect is not obvious, and it is hair The foam material is relatively thick and hard, and the adhesion is not good. It is easy to deform after aging, and the corners are easy to bulge due to overlapping. SUMMARY OF THE INVENTION [0003] The problem to be solved by the present invention is to provide a high water-resistance solar module edge-seal...
