Problems solved by technology

The film layer formed after curing of this kind of repair fluid has water resistance effect, but the water resistance effect is not good, and the fit is poor, the bonding strength is low, it is easy to fall off, and it is also easy to deform after aging, resulting in easy peeling and peeling at the corners of the attached film
In addition, this kind of repairing liquid is inconvenient to store and use, and its anti-ultraviolet performance, fogging and high temperature resistance are also poor. Therefore, it is necessary to conceive a high-performance repairing tape for photovoltaic module backplanes to solve the repair of damaged parts of solar backplanes. question

Abstract

The invention discloses a preparation method of a high-performance repair adhesive tape for a photovoltaic module backboard. The high-performance repair adhesive tape for the photovoltaic module backboard comprises a fluorine coated layer, a base material layer, a functional adhesive layer and a release material layer which are sequentially arranged from top to bottom, wherein the fluorine coated layer is prepared from organic resin, a curing agent and an inorganic filler, and the base material layer is made from a plastic film material. By specially modifying acrylic acid pressure-sensitive adhesive, namely introducing an antioxidant and an ultraviolet absorbent in an adhesive system, the weather resistance, high temperature resistance and yellowing resistance properties can be greatly improved, and the adhesive tape is high in bonding strength and is not likely to shed. In addition, the back side of the base material layer is coated with the fluorine coated layer, a base material can be protected against yellowing, the adhesive tape is convenient to adhere and convenient to construct.

Description

technical field [0001] The invention relates to the technical field of tapes, in particular to a preparation method of a high-performance repair tape for a photovoltaic module backplane. Background technique [0002] The solar backsheet is located on the back of the solar panel, which protects and supports the battery sheet, and has reliable insulation, water resistance, and aging resistance. The initial solar backsheet has a three-layer structure (PVDF / PET / PVDF), the outer protective layer PVDF has good environmental erosion resistance, the middle layer is PET polyester film with good insulation performance, and the inner layer PVDF and EVA have good Adhesive properties. At present, repairing liquid is used for repairing the damaged part of the solar backplane, or for strengthening the connection. The film layer formed after curing of this kind of repairing liquid has water resistance effect, but the water resistance effect is not good, and the fit is poor, the bonding st...
