Description

Water-blocking adhesive tape for photovoltaic module frame and preparation method thereof
Technical Field
The invention belongs to the field of water-blocking tapes, and particularly relates to a water-blocking tape for a photovoltaic module frame and a preparation method thereof.
Background
Photovoltaic modules, also called solar panels, generate electricity through the "photovoltaic effect" and are a central part of solar power generation systems. The solar photovoltaic component comprises a crystalline silicon component and an amorphous silicon thin film component, and the crystalline silicon component has the advantage of LCOE electricity cost, so that the crystalline silicon component is a mainstream product in the current market and accounts for more than 95% of the total.
The crystal silicon assembly mainly comprises two product types, wherein one type is that glass/packaging film/battery/packaging film/back plate is adopted for packaging, a metal aluminum frame is used as a frame, and the frame is bonded and fixed through silica gel, so that the packaging form occupies the leading position of the current market due to light weight, convenient installation and transportation and low manufacturing cost, and accounts for more than 90 percent of the product; the other method is to use glass/packaging adhesive film/battery/packaging adhesive film/glass for packaging, and does not use an aluminum frame.
For the components packaged in the form of metal aluminum frames and silica gel, in the early development stage of the industry (before 2014), photovoltaic component manufacturers mainly adopt a manual operation mode for leading the silica gel into aluminum frame grooves through a glue gun and then assemble the aluminum frame grooves through a frame filling machine due to the low production automation level and the low popularization rate. In order to avoid the pollution of the overflowing silica gel to the glass, the cleaning cost of the glass pollution caused by the silica gel is reduced, the use cost of the silica gel is reduced, and the use amount of the silica gel is artificially reduced by a component manufacturer, so that no silica gel overflows or lacks among the front surface, the frame and the glass of the solar component. Along with the long-term outdoor use of the solar modules, rainwater gradually flows into the module from the front side, namely a gap between glass and a frame, and water vapor gradually permeates into the module along with the accumulation of time, so that sensitive and fragile silver grid lines of a solar cell are corroded, and the performance attenuation of the solar module is aggravated; on the other hand, the use amount of the silica gel is reduced, so that the wet insulation performance of the solar module is reduced, serious potential safety hazards are generated, and the risk that a module manufacturer is claimed by a terminal customer or even prosecuted by law is increased.
CN109294475A discloses a water-blocking adhesive tape for a photovoltaic module frame and a preparation method and application thereof.

As can be seen from the data in table 1, the water vapor barrier performance of the two-layer (PVDF + PE, examples 3 and 4) and three-layer composite substrates (PVDF + PE + PCTFE, examples 5 and 6) is better (especially, PCTFE is added into the three-layer composite, which is more significant) than that of the single-layer substrate (PE, examples 1 and 2), the UV aging resistance is better, and the adhesive strength after the aging of the adhesive layer is improved greatly.
The substrate layer of embodiment 1, 2 is single membrane layer, and the joining of liquid butyl rubber in embodiment 2 has certain promotion to a certain extent compared with embodiment 1's bonding strength, and steam barrier property has reinforcing effect, and UV resistant ageing behavior also has certain promotion.
The use of butyl rubber as the base rubber in example 7 or liquid butyl rubber as the liquid rubber in example 8 significantly improves the overall bond strength.
The rubber oil of example 9, which was an aromatic oil, was poor in aging resistance, although it was improved to some extent in adhesive strength.
