The copolymer resin material and the manufacturing method thereof according to the preferred embodiment of the present invention are suitable for use in the field of packaging process technology of various electronic components (for example, packaging process of solar cell panels or semiconductor components), and the technical field of adhesive fixing processes of various products (for example, : Adhesive process in traditional industries], various technical fields of building sealing engineering (for example, door and window leak-proof filling engineering) or other process technology fields, but it is not intended to limit the scope of application of the present invention.

In general, a polymer resin material has the following characteristics: light weight, low cost, and good softness and adhesion properties. Therefore, polymer resin materials are widely used in the field of packaging technology of various electronic components.

The stress generated by the difference between different thermal expansions. Based on the consideration of the service life, environment, electrical properties, output power, etc. of the solar cell, the solar cell packaging material should have the following characteristics: low interfacial conductivity, high-strength bonding between the encapsulating material and the substrate, low hygroscopicity and thermal conductivity. Sex. Currently available solar module packaging materials include: thermoplastic polyurethane [TPU], thermoplastic polyolefin (TPO), ethylene-ethylene acetate Ester copolymer [EVA], polyvinyl butyral [PVB], polydimethyl siloxane (PDMS) or other materials.

At present, the two main solar panel encapsulating film materials are EVA and PVB, among which EVA materials are relatively cheap, and PVB materials are twice the price of EVA materials. Although EVA materials are widely used in solar cell packaging materials, they have poor stability and yellowing of materials under long-term ultraviolet (UV) irradiation. After the EVA material is irradiated by ultraviolet light, since the ultraviolet light energy is higher than the ESA material breaking energy, the acetic acid molecule can be decomposed, thereby corroding the metal wire of the twin crystal battery, and destroying the total output power of the solar cell. In addition, under the dual action of high temperature and oxygen, the EVA material forms a chromophore group of a long conjugated segment of the ketene structure during aging, thereby causing yellowing of the material or remaining in the solar panel packaging and pressing process. The bridging agent and additives also produce a slow reaction, which causes yellowing and embrittlement of the material, and further reduces the transparency of the material, and reduces the adhesion of internal components, thereby reducing the service life of the solar cell.
