Description
Technical field
The present invention relates to technical field of solar batteries, be specifically related to a kind of solar cell backboard weathering layer repair liquid.
Background technology
As the green replacement scheme of traditional production method of electric energy, photovoltaic cell component is used to utilize solar energy to produce electric energy.Photovoltaic cell component is formed by various semiconductor element system assembles, thus must be protected to reduce environmental activity as moisture, oxygen and ultraviolet impact and destruction.Photovoltaic cell component generally adopts glass, cell silicon chip, EVA, back veneer material hot pressing forms; therefore, the backboard with excellent electric insulating quality, bond strength between layers, weather resisteant, ultraviolet-resistent property and moisture barrier property plays important protective effect in photovoltaic cell component.
Usually, backboard is coated with by the fluorinated polymer material (weathering layer) with weatherability or is compounded in substrate surface and is formed.If weathering layer occurs to scratch or disrepair phenomenon; the EVA layer of its solar components inside protected directly can be subject to the corrosion of environment; aging or disengaging rapidly, then corrosion cell sheet part, along with the expansion of corrosion scope causes solar module short-circuit failure.
In existing solar components production and use procedure, the scuffing of backboard weathering layer happens occasionally.Once there is this situation, existing solution is module frame of directly dismantling, the backboard more renewed lamination again, the method complicated operation, constructs loaded down with trivial details and with high costs.Existing photocureable coating, owing to not reaching the long-term practical time limit of backboard with solar energy backboard weathering layer and the bad and weatherability of substrate bonding power thereof, is generally not used in the weathering layer repairing aspect of solar energy backboard.Therefore develop a repair liquid being exclusively used in solar energy backboard weathering layer and there is very high practical value.
Summary of the invention
Problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of solar cell backboard repair liquid, described repair liquid using method is simple, solidification rate is fast, there is good adhesive force with backboard base material, weathering layer, and have excellent ageing-resistant performance.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of solar cell backboard repair liquid, the component of described repair liquid and parts by weight thereof are:
Epoxy acrylic resin 20-30 parts,
Polyurethane acrylic resin 20-30 parts,
