Problems solved by technology

By selecting a weather-resistant base material layer, the effects of water resistance, insulation and ultraviolet radiation resistance can be achieved, and it can play the role of an independent backplane; the weather-resistant adhesive is used for the functional adhesive layer, which can improve the weather resistance, high temperature resistance, and yellowing resistance of the tape. , the tape has high bonding strength and is not easy to fall off. At the same time, the tape is easy to fit and easy to construct. However, this invention is bonded to the surface of the damaged backplane or cracked backplane to ensure the bonding strength and the base material can be used for insulation and wind and sand protection. And anti-ultraviolet function, its flexibility and fit are not good, and the waterproof effect needs to be further improved
[0006] At present, there is no good solution to solve the problem of water ingress in the silicone cracks in photovoltaic modules

Abstract

The invention provides a water-blocking adhesive tape for a frame of a photovoltaic module, a preparation method and application thereof. The water-blocking adhesive tape for the frame of the photovoltaic module includes a base material layer, an adhesive layer, and a release material layer. The adhesive layer is prepared from a water-blocking adhesive for the frame of the photovoltaic module. In total, the water-blocking adhesive for the photovoltaic module frame includes the following components: 100 parts of master resin, 0.1-10 parts of curing agent, 1-5 parts of antioxidant, and 0-5 parts of ultraviolet absorber. The water-blocking tape for photovoltaic module frames of the present invention has good flexibility when used for bonding photovoltaic module frames, is easy to fit, has good cohesiveness, high weather resistance, and does not become brittle, does not fall off, and does not yellow when used outdoors for a long time. No adhesive residue when peeled off.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and relates to a water-blocking adhesive tape for a frame of a photovoltaic module, a preparation method and an application thereof. Background technique [0002] Photovoltaic modules, also called solar panels, generate electricity through the "photovoltaic effect", which is the core part of the solar power generation system. Solar photovoltaic modules include crystalline silicon modules and amorphous silicon thin-film modules, and crystalline silicon modules are the mainstream products in the current market because of their LCOE cost advantage, accounting for more than 95% of the total. [0003] There are two main types of crystalline silicon components. One is packaged with glass / encapsulation film / battery / encapsulation film / backplane, and uses a metal aluminum frame as the frame, which is bonded and fixed by silica gel. The product is light in weight, easy to install and transport, and low ...
