Description

Primer, preparation method thereof and BIPV product
Technical Field
The application relates to the technical field of solar cells, in particular to a primer, a preparation method thereof and a BIPV product.
Background
In the decades of the 21 st century, energy shortage and environmental deterioration have been increasingly prominent. The 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 due to its advantages such as huge reserves, clean use, wide distribution, etc. The photovoltaic industry is considered as one of the major research points in each major country of the world and respective plans are successively introduced.
BIPV technology is a technology that integrates solar power (photovoltaic) products into buildings. In modern society, people are pursuing more and more comfortable building environments, and energy consumption of building heating and air conditioning is increasing day by day. In developed countries, building energy accounts for 30% -40% of total national energy consumption, and a certain restriction effect is formed on economic development. The combination of photovoltaic and buildings is a new blue sea with huge potential, can effectively reduce building energy consumption, vigorously develops low-carbon and zero-carbon buildings, and has important practical significance for energy conservation, emission reduction and environmental protection. The area of a finished house in China is about 40 hundred million square meters every year, 5 percent of the finished house is replaced by BIPV, and 1000 hundred million markets and blue sea exist.
BIPV has many different forms of installation, such as photovoltaic roofing, photovoltaic curtain walls, and photovoltaic ceilings. As an important application scenario of the BIPV, the photovoltaic roof has been widely paid attention from the photovoltaic industry, and more distributed photovoltaic investors, engineering parties and developers aim at the plant roof, including the renovation and the reconstruction of an old roof and the new construction of a factory roof. The roofing of industry factory building generally is die mould metal sheet structure, and assembled BIPV product combines roofing die mould metal sheet and photovoltaic module together and makes it become the roofing system that can generate electricity, and in this system, photovoltaic module and die mould metal sheet's connection is through the bonding of structural adhesive, and the structural adhesive that uses mainly is the silicone structural adhesive. The laminated metal sheet for roof usually has a structure of an outermost fingerprint-resistant layer, an intermediate coating layer and an intermediate substrate layer, and when the laminated metal sheet is bonded with a structural adhesive, the outermost fingerprint-resistant layer of the laminated metal sheet has the greatest influence on bonding, and the chemical components and the surface physical properties of the fingerprint-resistant layer influence the bonding of the structural adhesive. The good bonding effect between the structural adhesive and the profiled metal sheet needs to be realized by firstly wetting the surface of the profiled metal sheet by the structural adhesive and secondly forming a certain number of chemical bonds between the structural adhesive and the profiled metal sheet. However, the system has the following problems in the use process:
(1) the number of surface active groups of the profiled metal sheet used generally is reduced in order to enhance the corrosion resistance of the profiled metal sheet, because the more surface active groups, the easier the surface active groups adsorb corrosive media in the air, and the corrosion of the profiled metal sheet is accelerated, and the reduced number of active groups can cause the number of chemical bonds formed by bonding the profiled metal sheet and the structural adhesive to be small, so that reliable bonding cannot be formed.
(2) When the profiled metal sheet is used, water in the air can carry a corrosive medium to penetrate through the fingerprint-resistant layer and enter the profiled metal sheet to corrode the profiled metal sheet, so that the bonding between the structural adhesive and the profiled metal sheet is affected.
(3) The structural adhesive used needs to absorb moisture of air to participate in the curing reaction in the curing process, but for some environments with low temperature and low humidity, the moisture for curing is lacked in the environment, so that the curing reaction of the structural adhesive is weakened to influence the bonding performance of the system.

When the BIPV roof is subjected to structural adhesive bonding construction, a photovoltaic module needs to be bonded to the surface of a profiled metal plate of the roof through structural adhesive, different profiled metal plates have larger difference in bonding performance with the structural adhesive due to difference in material, and in the actual construction process, some profiled metal plates which are difficult to bond with the structural adhesive are often encountered. The profiled metal sheet lies in that the structure glues after the bonding when being on active service in the open air, and corrosive medium such as Cl ion in the air, S ion etc. can adsorb in the hydrone, enters into the inside of profiled metal sheet along with the hydrone to cause the corruption of profiled metal sheet, and the profiled metal sheet corruption time can make the bonding stability variation between structure glue and the profiled metal sheet, thereby influence the safety in utilization of BIPV product. In addition, after the construction of the structural adhesive is completed, about one month of curing time is needed, water molecules in the air are needed to participate in the curing reaction of the structural adhesive in the curing process of the structural adhesive, and if the humidity in the air is low, the curing of the structural adhesive is slowed down, so that the normal operation of the BIPV product is influenced.
