Problems solved by technology

The cleaning of photovoltaic module panels is mainly carried out by water washing, wind blowing and wiping, etc. The acidic and alkaline rainwater and the metal ions on the surface are often not cleaned, which will reduce the light transmittance of the photovoltaic panel glass. If things go on like this, the power generation efficiency of photovoltaic modules will decrease. More attenuation, even lead to premature scrapping of photovoltaic modules, causing huge losses to owners

Abstract

The invention discloses a protective tape for a photovoltaic module panel. The protective tape sequentially comprises a base material layer, an adhesive layer and a release layer, wherein the base material layer is composed of a high-water resistance aluminum-containing material film, ultra-thin glass, a long-acting weather-resistant anti-fouling film or modified PET (Polyethylene Terephthalate) film material; and the adhesive layer is composed of long-acting weather-resistant cohesion-retaining glue. The protective tape for the photovoltaic module panel disclosed by the invention has the advantages of being weather-resistant (acid-base, damp heat and ultraviolet), hydrolysis resistant, capable of being firmly bound to the photovoltaic module panel for a long time, anti-fouling, highly pervious to light, resistant to mechanical scratch, difficult in chemical corrosion, and capable of preventing from being adhered to dust. The dirt can be smoothly cleaned by virtue of washing and wiping, and even if natural rainwater and wind blows exist, cleaning can be completed.

Description

technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to a protective adhesive tape for photovoltaic module panels, a preparation method and a bonding method thereof. Background technique [0002] Photovoltaic modules are composed of panels + encapsulation + batteries + encapsulation + backplane / glass. The panel is transparent to light, and the backplane / glass can be transparent or impermeable to light. The panel is very important, and the light passes through The panels go into the assembly to generate electricity. Photovoltaic modules are used in a variety of environments, including the use in some harsh environments. A large amount of ash layer, a large amount of acidic and alkaline substances, metal oxides and polymer compounds are diffused in the air, which makes the ash layer on the surface of the module panel , sediment, and sulfur-containing, iron-containing powder and other substances in the air. The cleaning of photo...
