Background
During the last decade of the 21 st century, energy shortages and environmental worsening are increasingly prominent. Development of renewable energy sources instead of traditional energy sources is the only way to solve the above problems. Solar energy has recently become the most attractive renewable energy source because of its advantages of large reserves, clean use, wide distribution, etc. The photovoltaic industry is one of the key points of research in the major countries of the world, and the respective plans are successively put forward.
BIPV technology is a technology that integrates solar power generation (photovoltaic) products into a building. In modern society, people are increasingly pursuing comfortable building environments, resulting in increasing energy consumption for building heating and air conditioning. In developed countries, the energy consumption for construction accounts for 30% -40% of the total energy consumption of the whole country, and a certain restriction effect is formed on economic development. The combination of the photovoltaic and the building is a new blue sea with huge potential, can effectively reduce the energy consumption of the building, greatly develop low-carbon and zero-carbon buildings, and has important practical significance for energy conservation, emission reduction and environmental protection. About 40 hundred million square meters of building area is built every year in China, 5% of building information is replaced by BIPV, and 1000 hundred million markets and blue sea exist.

The structural adhesive and the profiling metal plate need to achieve good bonding effect, firstly, the structural adhesive can well wet the surface of the profiling metal plate, and secondly, the structural adhesive can form a certain number of chemical bonds with the profiling metal plate. However, this system has the following problems in use:
(1) In order to enhance the corrosion resistance of the commonly used profiled metal sheets, the number of surface active groups is generally reduced, because the more the surface active groups are, the more easily corrosive medium in the air is adsorbed, the corrosion of the profiled metal sheets is accelerated, the fewer the number of active groups, the fewer the number of chemical bonds formed between the profiled metal sheets and the structural adhesive, and the reliable adhesion cannot be formed.
(2) In the use process of the profiling metal plate, water in the air can carry corrosive medium to penetrate through the fingerprint-resistant layer and enter the profiling metal plate to enable the profiling metal plate to be corroded, and adhesion between the structural adhesive and the profiling metal plate is affected.
(3) The used structural adhesive needs to absorb moisture of air to participate in the curing reaction in the curing process, but for some low-temperature and low-humidity environments, the lack of moisture for curing in the environment can lead to weakening of the curing reaction of the structural adhesive and influencing of the bonding performance of the system.
