Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the description and claims of the present invention and the above-described drawings, are intended to cover a non-exclusive inclusion, such that a process, method, apparatus, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The raw material manufacturers used in the invention are as follows:
acrylic resin PD-9200: anderson, USA
Ethylene-methacrylic acid copolymer: shanghai accurate biotechnology
Curing agent DDDA: japanese ministry of Japan
Leveling agent PL 200A: estron, USA

TABLE 1
The preparation method of the powder coating for the photovoltaic cell panel comprises the following steps:
(1) preparation of modified acrylic resin: the acrylic resin and the ethylene-methacrylic acid copolymer are mixed in proportion, and are subjected to melt extrusion by a double-screw extruder at the temperature of 100 ℃, tabletting and crushing to prepare the modified acrylic resin.

Examples of the experiments
TABLE 2
As can be seen from the data in table 2, the three-layer structure of examples 1-2 has significantly better adhesion than comparative examples 1-5.
