10 parts, 10-20 parts of cosolvent.The invention passes through the selection of light-cured resin and initiator, is made by way of ultraviolet irradiation
The rapid film-forming of coating, while the addition of fluorine resin is so that coating has good chemical proof and excellent resistance to old
Change performance, the coating and backboard substrate, weathering layer that the repair liquid is formed have good adhesive force, and with excellent weather-proof
Property, it can be improved production efficiency, reduce the cost of the new backboard of integral replacing.But the solar cell backboard of the invention is repaired
Preparing for liquid has used light-cured resin and initiator in raw material, need 30-40 DEG C of heating treatment, and curing time is longer, because
This applies that man-haur efficiency is to be improved, block-water performance, yellowing resistance and the ultraviolet light resistant performance of repair liquid obtained also need into
One step improves.
Currently, suitable method for repairing and mending is not found also for solar cell backboard damaged part, it can only be to damaged group
Part carries out whole replacements, and this method can only carry out the replacement of a small amount of component, and cost is high if high-volume is replaced, and old component returns
It is difficult to receive, and also easily causes environmental pollution；Given this background develops a kind of photovoltaic component back plate patching material, with excellent resistance to
Hou Xing, heat-resisting quantity and anti-yellowing property have bonds well power with backboard, can construct at the scene, environmental protection is without waste, cost
It is cheap, make damaged component that can run well within quality guarantee period, is of great significance.
